Comparison of blood loss in total knee replacement surgery with and without tranexamic acid: a prospective, time framed and observational analytical study

Background: Total knee replacement is one of the common orthopaedic procedures performed worldwide. Blood transfusion is one of the major requirements in TKR procedure due to the amount of blood loss during and after the procedure. We carried out a prospective study to determine the efficacy of tranexamic acid in controlling blood loss during TKR procedure. Methods: Study was conducted at a tertiary care centre, involving cases operated by a single surgeon. Study included 140 patients undergoing primary TKR for advance degenerative disease of knee and were divided into two groups of 70 each, one group that received tranexamic acid before surgery and another group that did not receive tranexamic acid before surgery. Patient with allergy to the drug, hepato/renal dysfunction, DVT, abnormal PT and INR were not included. Tranexamic acid was given intravenously as well as intra-articular. Results: Pre-operative haemoglobin ranged from 10.2 gm% to 14.4 gm% in the group getting tranexamic acid and from 10% to 14 % in the group not getting tranexamic acid. Post operatively haemoglobin varied from 8.4 gm% to 12.8 gm% in Group 1 and from 7.8 gm% to 12 gm% in Group 2. Difference of mean post-operative Hb (p=0.0045) and PCV (p=0.0024) in two groups was statistically significant. Conclusions: We concluded that administration of tranexamic acid reduces the blood loss as well as need of blood transfusion in a patient undergoing total knee replacement.

Tendencias en la cirugía de artroplastía total de rodilla en Chile. ¿Cómo las estamos operando? / Trends in total knee replacement surgery in Chile. How are we operating them?

INTRODUCCION La artroplastía total de rodilla (ATR), que ha tenido un aumento importante en la población en las últimas décadas, presenta una gran variación en su estudio y técnica entre los distintos países. En la actualidad no hay datos nacionales registrados que evalúen la forma de su implementación. Objetivo Registrar las tendencias respecto de la ATR en distintos aspectos en Chile y compararlas con los registros de otros países. MATERIALES y METODOS Se realizó una encuesta vía email a cirujanos de rodilla en Chile considerando cuatro aspectos: generalidades, estudio preoperatorio, técnica quirúrgica y técnica de cementación. Se excluyeron las encuestas que no rellenadas por completo. Se analizaron los datos generales y separados según años de experiencia (ADE). Se compararon los datos con los obtenidos en estudios internacionales. RESULTADOS Se obtuvieron 87 encuestas completas. La mayoría de los encuestados realizaba entre 25 y 50 ATR en 1 año (44%), y el 16%, más de 75. Sólo un 20% utilizaba la modalidad ambulatoria, y un 43% creía que siempre deben ser hospitalizadas (mayor frecuencia en los cirujanos con más de 10 ADE). Un 18% utilizaba algún sistema robótico, con mayor frecuencia en cirujanos con más de 10 ADE; los sistemas más usados fueron ROSA y CORI. El 90% creía que la ATR debería ser parte del programa de Garantías Explícitas de Salud (GES), sin diferencias según ADE. El 81% usaba sistema estabilizado posterior (posterior-estabilized, PS, en inglés), 96% realizaba un abordaje parapatelar medial, 82% usaba guía extramedular tibial, 41% tendía a recambiar la patela, y un 35% no usaba torniquete (ninguna de las variables mostró diferencias según ADE). Sólo un 31% utilizaba cementación al vacío (mayor frecuencia en el grupo con menos de 10 ADE), 95% colocaba el cemento en componentes y en hueso, 75% colocaba en la quilla, y 56% utilizaba el dedo para colocarlo (sólo 22% con pistola). La secuencia más frecuente de cementación fue tibia-fémur-patela. En la mayoría de los aspectos evaluados, se observaron diferencias importantes con estudios de otros países. CONCLUSION Existe una gran variabilidad en la realización de ATR en Chile, con tendencias distintas a las de otros países. En general, en relación con los distintos ADE, no hay grandes diferencias en la técnica quirúrgica, sí habiendo diferencias en la técnica de cementación y en el uso de sistemas robóticos

INTRODUCTION Total knee replacement (TKR) significantly increased among the population in recent decades, and it shows great variation in its study and technique in different countries. There is no registered Chilean data to assess TKR implementation. Objective To record the trends in TKR in different aspects within Chile and compare them with records from other countries. MATERIALS AND METHODS We conducted an email survey among knee surgeons in Chile considering four aspects: general features, preoperative study, surgical technique, and cementation technique. We excluded surveys not completed in full. The analyses included overall data and data per years of experience (YOEs), and we compared the results with those of international studies. RESULTS We obtained 87 complete surveys. Most respondents performed 25 to 50 TKRs each year (44%), with only 16% performing over 75 TKRs. Only 20% used the ambulatory modality, while 43% believed patients always require hospitalization (especially surgeons with more than 10 YOEs). Robotic systems were used by 18% of the surgeons, especially those with more than 10 YOEs; the most used systems were ROSA and CORI. In total 90% of the respondents believed TKR should be part of the Explicit Health Guarantees (Garantías Explícitas de Salud, GES, in Spanish) program, with no differences in terms of YOEs. A total of 81% used the posterior-stabilized (PS) system, 96% performed a medial parapatellar approach, 82% used an extramedullary tibial guide, 41% tended to replace the patella, and 35% did not use a tourniquet (none of the variables showed differences according to YOEs). Only 31% used vacuum cementation (with a higher frequency in the group with fewer than 10 YOEs), 95% placed cement on components and bone, 75% placed it in the keel, and 56% used finger packing (only 22% with a gun). The most common cementation sequence was tibia femur-patella. In most aspects evaluated, we observed important differences compared with studies from other countries. CONCLUSION There is a high variability in the performance of TKR in Chile, with different trends compared with those of other countries. Overall, there are no major differences in the surgical technique concerning YOEs, although there is variation in the cementation technique and the use of robotic systems

Establishment and assessment of a postoperative delirium risk scale for elderly patients undergoing hip and knee replacement / 临床麻醉学杂志

Objective To construct a risk assessment scale for postoperative delirium(POD)in elderly patients undergoing hip and knee joint replacement and evaluate the effect.Methods A total of 474 elderly patients undergoing hip and knee arthroplasty from March 2021 to May 2022 were collected as the training set,and a total of 153 the homogeneous patients from January 2022 to May 2022 were collected as the validation set.The patients were divided into two groups based on whether or not POD occurred:non-POD group and POD group.Risk factors of POD in the training set were analyzed by univariate analysis and multifactorial logistic regression.The consistency of the model was evaluated by Homser-Lemeshow goodness of fit test.The postoperative delirium risk assessment scale was established after the selected variables as-signed value according to OR value,and the predictive efficacy of the scale was evaluated by receiver oper-ating characteristic(ROC)curve.The patients in the training set and the validation set were divided into two groups according to the cut-off value:high-risk and low-risk.The incidence rate of POD with different risk stratification was calculated and the applicability of the risk assessment scale was evaluated.Results Fifty-eight patients(12.2%)with POD in the training set,and nineteen patients(12.4%)with POD in the validation set.Multifactor logistic regression showed that age≥85 years,ASA physical status Ⅲ or Ⅳ,the mini-mental state examination(MMSE)score≤24 points,preoperative sleep disorder,comorbid neu-rological disorders,use of general anesthesia,and non-use of dexmedetomidine were independent risk factors of POD.The POD risk assessment scale was then published based the seven risk factors.The ROC curve showed that the area under the curve(AUC)for this scale to predict the risk of POD was 0.956(95%CI 0.937-0.975),and the risk stratification was performed with a cut-off value of 44.5 points,which divided the patients into low-risk and high-risk.Compared with low-risk,the incidence rate of POD in high-risk patients group was significantly increased(P＜0.001).Conclusion A risk assessment scale based on the seven risk factors:age≥85 years,ASA physical status Ⅲ or Ⅳ,MMSE score≤24 points,preoperative sleep disorder,combined neurological disease,use of general anesthetic modality,and non-use of dexmedetomidine,can effectively identify elderly patients undergoing hip and knee replacement who are at high risk of developing POD.

Does total knee arthroplasty affect pelvic movements? A prospective comparative study

SUMMARY OBJECTIVE: Pathology in any segment of the spine-pelvis-lower extremity may impair the global postural balance, leading to compensatory alterations in other parts. The aim of this study was to compare the pelvic movements of patients suffering from knee osteoarthritis with patients who underwent total knee arthroplasty and healthy controls. METHODS: This study was performed at the Department of Orthopedics and Traumatology Clinic of a Cankiri State Hospital between April 2021 and February 2022. This study included 84 participants. Of them, 31 patients who underwent total knee arthroplasty between 2018 and 2020 years were selected as the total knee arthroplasty group, while 28 patients with knee osteoarthritis were selected as the knee osteoarthritis group. In the control group, there were 25 healthy individuals. Exclusion criteria from the study included any kind of neurological disease, an inability to walk a distance of 100 m unassisted, or a history of surgery to the lower limb. Pelvic movements (i.e., tilt, rotation, and obliquity) and gait parameters (i.e., "gait velocity," "cadence," and "stride length") were assessed using a wireless tri-axial accelerometer. RESULTS: Total knee arthroplasty and control groups had decreased minimum anterior tilt of the pelvis, decreased maximum anterior tilt, and decreased oblique range of the pelvis compared with the knee osteoarthritis group. In comparison with the control group, gait velocity and length of stride during gait were remarkably lower in both knee osteoarthritis and total knee arthroplasty groups. CONCLUSION: In this study, total knee arthroplasty was found to affect pelvic movements. It was thought that total knee arthroplasty changed these variables, probably owing to the frontal and sagittal plane alignment correction through surgery.

Functional evolution in total knee arthroplasty: first and second-generation patient-specific instrumentation compared with conventional instrumentation

Background: This study compares the functional evolution between the first- and second-generation patient-specific instrumentation and conventional instrumentation pre-surgery and the third month post-surgery after TKA. We analyzed the functional outcomes achieved and the absolute gains of each study variable. In addition, we aimed to elucidate the results of the three surgical techniques regarding the surgery length of time, length of hospital stay, percentage drop in hemoglobin (Hg) at 24 h, and hip-knee-ankle angle post-surgery. Methods: We reported our experience in TKA using PSI Visionaire System® and CI technique in 688 procedures. The patients were divided into first (N=272) and second-generation (N=151) PSI designs. The control group (N=265) underwent TKA with the CI. The instruments for assessing the functioning were: visual analog scale, goniometry, 6-minute walk test (6MWT), and domains of the WOMAC Index. Results: The functioning achieved three months after surgery was lower in the CI than the first-generation PSI. The respective differences at absolute gains were found in the 6MWT and pain and function WOMAC scores (p=0.023, p=0.049, and p=0.018, respectively). The mean surgical time was higher in the CI compared to PSI designs (both p<0.001), and the mean hospital length of stay was higher in the CI compared to second-generation PSI (p=0.002). The percentual drop in Hg was higher in the first-generation PSI than with the CI (p=0.006). Conclusions: Three months after TKA, the functioning achieved with the first-generation PSI was greater than the CI. However, the functional results between second-generation PSI and CI were similar.

Abstract: Introduction: revision total knee arthroplasty (TKA) is a challenging procedure that requires proper alignment, restoration of bone loss, and prevention of instability. Modern revision systems offer progressive implant constriction with multiple options for offset, augmentation, and fixation stems. Objective: to evaluate the clinical outcomes of a modular implant with hybrid fixation in revision TKA with a minimum follow-up of two years. Material and methods: we retrospectively included all revision TKA surgeries performed between September 2018 and September 2019, using the same implant. Patient demographics, comorbidities, and data on bone defects were recorded. Clinical outcomes were assessed using subjective roles and Maudsley scores and the Knee Society Score (KSS). Complications during follow-up were also documented. Results: a total of 23 patients were analyzed, comprising 65% females and 35% males, with a median age of 71.1 years. Bone defects following implant removal were classified as F2.T2 in 39.13% of cases, F1.T2 in 8.69%, and F1.T1 in the remaining 52.17%. There were significant improvements in the KSS score (preoperative: 53 points, postoperative: 79 points; p < 0.001). Three (13%) complications were reported, two of which were directly related to the surgery, and two patients required subsequent revision surgery. The 2-year survival rate was 91.3%. Conclusion: the use of a modular implant with hybrid fixation in revision TKA demonstrated a high 2-year survival rate, significant improvements in clinical scores, and a low incidence of short-term complications. These findings support the efficacy and safety of this approach, providing favorable clinical outcomes and high patient satisfaction.

Radiografía al acceso en artroplastia de rodilla entre los beneficiarios del Fondo Nacional de Salud entre 2004 y 2021 / Access to knee arthroplasty among National Health Fund beneficiaries in Chile between 2004 and 2021

INTRODUCCIÓN: La artrosis de rodilla es una patología que afecta la calidad de vida, siendo la artroplastía de rodilla un tratamiento costo-efectivo para la etapa severa de esta enfermedad. El acceso a artroplastia de rodilla es un indicador de salud de la Organización de Cooperación y Desarrollo Económico. Los objetivos de este estudio son determinar la incidencia de artroplastia de rodilla entre 2004 y 2021 en los beneficiarios del Fondo Nacional de Salud en Chile, la proporción que se operaron en el sistema privado y estimar el gasto del bolsillo del paciente para operarse. MÉTODO: Estudio transversal. Se utilizó la base de datos del Departamento de Estadística e Información de Salud. Se pesquisaron pacientes que egresaron de un centro de salud chileno que fueron intervenidos por artroplastia rodilla entre 2004 y 2021. Se analizó la proporción de pacientes por tramo del Fondo Nacional de Salud y si se realizó su cirugía en establecimiento de la red pública o privada. RESULTADOS: De las 31 526 intervenciones de artroplastia de rodilla, 21 248 (67,38%) fueron realizadas en pacientes del Fondo Nacional de Salud y 16 238 en instituciones públicas (51,49%). Los pacientes de dicho fondo presentan un alza sistemática en el volumen de artroplastías de rodilla hasta 2019, pero disminuyeron en 2020 y 2021 un 68% y un 51%. Del total de pacientes del sistema público operados de artroplastia de rodilla, 856 (9%) pertenecían al tramo A1, al tramo B 12 806 (60%), al tramo C 2044 (10%) y al tramo D 4421 (21%). Se estimó que el gasto incurrido por estos pacientes varía entre el 24,4 y 27,2%. Las proporciones históricas de acceso en instituciones privadas a esta cirugía son en el tramo A 7%, tramo B 13%, tramo C 24% y tramo D 52%. CONCLUSIÓN: El 50% de las cirugías de artroplastía de rodilla se realizan en instituciones públicas y dos tercios se realizan en pacientes del Fondo Nacional de Salud. El 46% de los tramos C y D se operaron en el sistema privado. La pandemia ha aumentado la brecha de acceso, lo que ha provocado un alza significativa en la proporción de pacientes del Fondo Nacional de Salud de los tramos B, C y D que han migrado al sistema privado para acceder a esta cirugía.

INTRODUCTION: Knee osteoarthritis affects the quality of life, with knee arthroplasty being a cost-effective treatment for the severe stage of this disease. Access to knee arthroplasty is a health indicator of the Organisation for Economic Co-operation and Development. The objectives of this study are to determine the incidence of knee arthroplasty between 2004 and 2021 in beneficiaries of the National Health Fund in Chile, the proportion of patients who underwent surgery in the private system, and to estimate the patient's out-of-pocket expenditure for surgery. METHODS: Cross-sectional study. We used the Department of Statistics and Health Information database. Patients discharged from a Chilean health center who underwent knee arthroplasty surgery between 2004 and 2021 were investigated. We analyzed the proportion of patients by their National Health Fund category and whether their surgery was performed in public or private network facilities. RESULTS: Of the 31 526 knee arthroplasty procedures, 21 248 (67.38%) were performed on National Health Fund patients and 16 238 in public institutions (51.49%). Patients from the National Health Fund showed a systematic increase in knee arthroplasty volume until 2019 but decreased in 2020 and 2021 by 68% and 51%. Of the total number of patients in the public system operated on for knee arthroplasty, 856 (9%) belonged to group A1, 12 806 (60%) to group B, 2044 (10%) to group C, and 4421 (21%) to group D. The expenditure incurred by these patients was estimated to vary between 24.4% and 27.2%. The historical proportions of access to this surgery in private institutions are 7% in group A, 13% in group B, 24% in group C, and 52% in group D. CONCLUSION: Fifty percent of knee arthroplasty surgeries are performed in public institutions, and two-thirds are performed on patients of the National Health Fund. Forty-six percent of the C and D groups were operated in the private system. The pandemic has increased the access gap, leading to a substantial increase in the proportion of patients from the National Health Fund of the B, C, and D groups who have migrated to the private system to access this surgery.

Inkk Trial - Intraoperative ketamine for perioperative pain management following total knee endoprosthetic replacement in oncology: a double-blinded randomized trial

Abstract Background There has been a growing interest in the use of ketamine following orthopedic surgeries. We hypothesized that low dose intravenous ketamine during surgery would help in mobilization following total knee replacement (TKR) in oncology patients as assessed by the timed to up and go (TUG) test at 72 hours post-surgery. Our secondary objectives were to compare the opioid requirement at the end of 72 hours, pain scores, satisfaction with pain management, adverse effects, range of joint movement achieved in the post-operative period and the functional recovery at the end of 1 month. Methods After the ethics commitee approval, registration of the trial with the Clinical Trial Registry - India (CTRI), and informed consent, this double-blinded trial was conducted. Using computer generated randomization chart, an independent team randomized the patients into ketamine group which received at induction, a ketamine bolus dose of 0.5 mg.kg-1 before the incision followed by 10 µg.kg-1min-1 infusion which was maintained intraoperatively till skin closure and the saline group received an equivalent volume of saline. Postoperatively, patient controlled morphine pumps were attached and the pain score with morphine usage were recorded for 72 hours. The TUG tests and range of motion were assessed by the physiotherapists until 72 hours. Results Fifty-two patients were enrolled in the trial. Demographics were comparable. No significant intraoperative hemodynamic changes and post-operative adverse events were noted between the groups. A decrease in the TUG test, along with decreased opioid usage with a better range of movements was noted in the ketamine group, but this was not statistically significant. Day of discharge, patient satisfaction score, and functional recovery assessed by Oxford Knee Score (OKS) were comparable between the groups. Conclusion In conclusion, low dose intraoperative ketamine infusion does not provide clinical benefit in perioperative pain management and postoperative rehabilitation following total knee endoprosthetic replacement in oncology.

Value of personalized osteotomy in primary total knee arthroplasty for severe varus knee osteoarthritis / 中国骨伤

OBJECTIVE@#To explore application value and efficacy of personalized osteotomy in primary total knee arthroplasty (TKA) for severe varus knee osteoarthritis.@*METHODS@#From June 2018 to January 2020, 36 patients (49 knees) with severe varus knee osteoarthritis were treated, including 15 males (21 knees) and 21 females (28 knees), aged from 59 to 82 years old with an average of (67.6 ± 6.5) years old;the course of disease ranged from 9.5 to 20.5 years with an average of (15.0 ± 5.0) years;11 patients (15 knees) with Kellgren-Lawrence grade Ⅲ and 25 patients (34 knees) with grade Ⅳ according to Kellgren-Lawrence grading. According to AORI clsssification of tibial bone defects, 8 patients (15 knees) were typeⅠTa and 16 patients (18 knees) were typeⅡ T2a. All patients' femor-tibial angle (FTA) was above 15°, and received primary TKA with personalized osteotomy. Thirty-three patients (45 knees) were treated with posterior-stabilized (PS) prostheses, 13 patients (15 knees) with PS prostheses combined with a metal pad and extension rod on the tibial side, and 3 patients (4 knees) with legacy constrained condylar knee (LCCK) prostheses. FTA, posterior condylar angle (PCA), medial proximal tibial angle (MPTA) and lateral distal femoral angle (LDFA) before and after operation at 1 month were measured and compared by using picture archiving and communication systems (PACS). Recovery of lower limbs before and after operation at 12 months was evaluated by American Knee Society Score(KSS), and complications were observed and recorded.@*RESULTS@#All 36 patients (49 knees) were followed up from 15 to 40 months with an average of (23.46±7.65) months. FTA, MPTA were corrected from preoperative (18.65±4.28)° and (83.75±3.65)° to postoperative (2.35±1.46)° and (88.85±2.25)° at 1 month, respectively (P<0.001). PCA was decreased from (2.42±2.16)° before operation to (1.65±1.35)° at 1 month after operation, LDFA improved from (89.56 ± 3.55)° before operation to (91.63±3.38)° at 1 month after operation (P<0.05). KSS increased from (67.58±24.16) before opertion to(171.31±15.24) at 12 months after operation, 14 patients (19 knees) got excellent result, 19 (26 knees) good, and 3 (4 knees) fair.@*CONCLUSION@#Personalized osteotomy is helpful for recovery of axial alignment of lower limbs and correct placement of prosthesis, could effectively relieve pain of knee joint, recover knee joint function.

Analgesia effect of dexamethasone combined with dexmedetomidine on femoral nerve block with ropivacaine after total knee replacement in elderly patients / 药学实践与服务

Objective To observe the analgesia effect of dexamethasone combined with dexmedetomidine on femoral nerve block with ropivacaine after total knee replacement in elderly patients. Methods 96 elderly patients undergoing total knee replacement with femoral nerve block analgesia from January 2019 to December 2020 in the hospital were enrolled in the study. Patients were divided into control group (C), dexamethasone group (E1), dexmedetomidine group (E2) and dexamethasone combined with dexmedetomidine group (E3) according to nerve block drug formulation. The general data and operation condition were collected, the VAS score at 6 h, 12 h, 24 h, 48 h and the Ramsay sedation score at 6 h after surgery were compared, the postoperative morphine consumption and duration of analgesia were analyzed, and the incidence of adverse reactions after operation was observed. Results Patients in four groups showed no significant differences in general data and operation time. The VAS score and Ramsay score at 6 h postoperatively in E2 and E3 were significantly lower than that in C, while there were no significant differences in VAS score at 24 h and 48 h postoperatively among four groups. Postoperative morphine consumption in E2 and E3 was significantly lower, and the duration of analgesia in E1, E2 and E3 was significantly longer than that in C. There was no statistical difference in the incidence of respiratory depression, nausea, vomiting, dizziness and other adverse reactions after operation among four groups. Conclusion Dexamethasone combined with dexmedetomidine could enhance the analgesic effect of femoral nerve block with ropivacaine in elderly patients after total knee replacement without increasing the adverse reactions, which would be both safe and effective.

Influence of patelloplasty combined with cartilage surface resection on early function and anterior knee pain during total knee arthroplasty / 国际外科学杂志

Objective:To investigate the effects of patelloplasty combined with cartilage surface resection on early function and anterior knee pain during total knee arthroplasty(TKA).Methods:This is a prospective controlled study, 100 patients with knee osteoarthritis(KOA) who received TKA treatment in Zoucheng People′s Hospital of Shandong Province from February 2021 to April 2022 were selected and divided into the combined group and the control group using the random number table method, 50 cases in each group. The combined group received patelloplasty combined with cartilage surface resection during TKA, while the control group only received patelloplasty. Preoperative osteoarthritis Kellgren-Lawrance (K-L) grade, joint motion (ROM), the operation time and the decrease of hemoglobin in two groups were recorded.Knee function was evaluated by Hospital for Special Surgery(HSS) knee score at 1, 3, 6, and 12 months after surgery. Anterior knee pain during stair climbing was evaluated by visual analogue scale(VAS), and recovery of patellofemoral joint was evaluated by Feller score system. The measurement data were represented as mean±standard deviation( ± s), and the comparison between groups was conducted using the t-test; the comparison of count data between groups was conducted by Chi-square test. Results:There was no significant difference in preoperative K-L grading and ROM between the two groups ( P> 0.05). The operation time of the combined group was longer than that of the control group[(71.49±9.34) min vs (66.27±8.22) min], the difference was statistically significant ( P <0.05), and there was no statistical significance in the decrease of hemoglobin between the two groups ( P>0.05). At 3, 6 and 12 months after treatment, the HSS scores of the combined group were higher than those of the control group [3 months: (76.93±8.26) vs (71.74±7.84), 6 months: (85.72±6.27) vs (81.47±6.19), 12 months: (88.64±5.27) vs (85.72±4.85)], the difference were statistically significant ( P <0.05). At 1, 3, 6 and 12 months after treatment, the VAS scores of anterior knee pain in combined group were lower than those in control group [1 months: (2.54±0.48) vs (2.77±0.63), 3 months: (2.02±0.53) vs (2.58±0.45), 6 months: (1.32±0.35) vs (1.97±0.38), 12 months: (1.14±0.33) vs (1.75±0.35)], the difference were statistically significant ( P <0.05). The incidence of anterior knee pain at 3, 6 and 12 months after operation in combined group was lower than that in control group [3 months: 20.0% vs 38.0%, 6 months: 14.0% vs 32.0%, 12 months: 10.0% vs 28.0%], the difference were statistically significant ( P <0.05). At 3, 6 and 12 months after treatment, the patellar Feller score in the combined group was higher than that in the control group[3 months: (18.63±3.52) vs (15.36±3.28), 6 months: (22.27±3.18) vs (19.63±3.48), 12 months: (25.82±3.27) vs (22.47±3.47)], the difference were statistically significant ( P <0.05). Conclusion:Patelloplasty combined with cartilage surface resection during TKA can effectively prevent the occurrence of postoperative anterior knee pain and improve the therapeutic effect.

Objective:To evaluate the influence of wearable devices on rehabilitation effect of patients after knee arthroplasty by using Meta-analysis method.Methods:Computer retrieval was performed on China National Knowledge internet(CNKI),Wanfang database,China science and technology journal database(VIP),PubMed and Cochrane Library databases to search the randomized controlled trials(RCTs)of applying wearable devices in the rehabilitation management of patients after knee arthroplasty during the period between March 2010 and July 2022.Two researchers independently screened literatures,evaluated quality and extracted documents according to the inclusion and exclusion criteria in this research.The Stata12.2 software was used to conduct Meta-analysis on the qualified literature.The Hospital for Special Surgery(HSS)knee function score,knee range of motion(ROM),Western Ontario and McMaster Universities Arthritis Index(WOMAC)score,Timed Up and Go Test(TUGT)assessment,postoperative steps and Visual Analogue Scale(VAS)score were selected as outcome indicators.Results:A total of 8 literatures were included finally in the meta-analysis.The 8 studies of 8 literatures involved 718 patients who underwent knee arthroplasty,of which included 359 cases who adopted wearable devices to conduct rehabilitation intervention after surgery in the observation group and 359 cases who adopted routine discharge rehabilitation guidance in the control group.Compared with the control group,the postoperative rehabilitation intervention with wearable device of observation group could improve ROM score(SMD=0.64,95%CI:0.13～1.15,P<0.05),TUGT score(SMD=-0.39,95%CI:-0.75～-0.03,P<0.05),WOMAC score(SMD=1.37,95%CI:0.92-1.82,P<0.05)and postoperative steps(SMD=0.56,95%CI:0.13～0.98,P<0.05).However,the differences of HSS score(SMD=0.22,95%CI:-0.64～1.07,P>0.05)and VAS score(SMD=0.18,95%CI:-1.10～0.75,P>0.05)between two groups were not significant.Conclusion:The application of wearable devices in rehabilitation of postoperative patients who undergo knee arthroplasty can significantly improve the ROM,TUGT assessment,WOMAC score and the postoperative steps of patients,and can improve the knee joint function of patients,and can promote the rehabilitation of knee function of patients after knee arthroplasty.

Prevalencia de portación nasal de Staphylococcus aureus sensible y resistente a la meticilina en candidatos a artroplastia total de cadera o rodilla / Prevalence of nasal carriage of methicillin-sensitive and methicillin-resistant Staphylococcus aureus in candidates for total hip or knee arthroplasty

INTRODUCIÓN Las infecciones perioperatorias en cirugía de reemplazo articular son fuente importante de morbimortalidad, así como de altos costos económicos y sociales, tanto para el paciente como para su entorno. La colonización preoperatoria por Staphylococcus aureus ha sido reconocida como un factor de riesgo importante para desarrollar una infección de sitio quirúrgico.El objetivo de este estudio es conocer la prevalencia de portación nasal de S. aureus, tanto sensible a la meticilina (SASM) como resistente a la meticilina (SARM), en pacientes candidatos a cirugía de reemplazo articular de cadera o rodilla. MATERIALES Y MÉTODOS Se realizó un estudio observacional de una cohorte retrospectiva de pacientes con indicación de artroplastia total de cadera (ATC) y rodilla (ATR) electiva por artrosis severa en un hospital público de Chile. Los pacientes fueron sometidos a tamizaje preoperatorio de portación, cultivándose muestras obtenidas mediante hisopado de ambas fosas nasales. Los datos del laboratorio fueron recopilados y presentados como porcentaje de portación de S. aureus. RESULTADOS Se estudiaron 303 pacientes consecutivos de ATC y 343 de ATR. En total, 483 de los 646 pacientes (74,7%) tuvieron estudio preoperatorio de portación nasal. Se identificaron 123 pacientes (25,4%) portadores de S. aureus, de los cuales sólo 2 (0,41%) casos correspondieron a SARM. CONCLUSIÓN La prevalencia de portación nasal de S. aureus obtenida fue de 25%, similar a lo reportado en otras series. La prevalencia de SARM (0.41%), sin embargo, estuvo bajo lo descrito en la literatura internacional (0,6­6%). Sería de utilidad, dada la alta prevalencia de portación descrita en nuestro trabajo y de acuerdo a evidencia publicada recientemente, realizar protocolos de descolonización universales, sin necesidad de realizar tamizaje preoperatorio.

INTRODUCTION Surgical-site infections in joint replacement surgery are an important source of morbidity and mortality that entail high economic and social burden both for the patient and their environment. Preoperative colonization by Staphylococcus aureus has been recognized as an important risk factor for the development of surgical-site infection. The aim of the present study is to determine the prevalence of nasal colonization by S. aureus, both methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) in patients who are candidates for total replacement of the hip or knee joints. MATERIALS AND METHODS A retrospective observational study of a cohort of 646 patients with an indication to undergo total hip arthroplasty (THA) or total knee arthroplasty (TKA) due to severe osteoarthritis was performed in a Public Hospital in Chile. The patients were submitted to a preoperative screening for S. aureus carriage, and the culture samples were obtained by swabbing both nostrils. The laboratory data was collected and presented as a percentage of carriage. RESULTS We consecutively examined 303 THA and 343 TKA patients. A total of 483 of the 646 patients (74.7%) underwent a preoperative study of nasal carriage. We identified 123 (25.4%) S. aureus carriers, and only found 2 (0.41%) cases corresponding to MRSA. CONCLUSION We found a prevalence of nasal carriage of S. aureus of 25.4%, a rate similar to that reported in other series. The prevalence of MRSA (0.41%), however, was lower than that reported in the international literature (0.6­6%). Given the high prevalence of carriage described in our work and according to recently published data, it would be worthwhile to carry out universal decolonization protocols, without the need for preoperative screening.

Effectiveness of continuous passive motion after total knee replacement: A randomized controlled trial from North India

Background: Continuous passive motion (CPM) is a common strategy for early post-operative rehabilitation of patients who have undergone knee surgery. During an early recovery time following primary total knee replacement (TKR), the efficiency of the CPM approach was evaluated in this study. Aim and Objective: To determine the effectiveness of using a CPM device for individuals with poor ROM after a TKR as compared with non CPM device users. Materials and Methods: Fifty-four TKR patients were distributed into two groups. CPM and exercises were given to the study group, while exercises were given to the control group only. All individuals were assessed for mean active range of motion (AROM), mean Knee Society Score (KSS), and the Western Ontario and MacMaster Universities Osteoarthritis Index before and after surgery (WOMAC). Results: The study group’s mean AROM was 81.7 ± 15.1, while the control group’s was 75.4 ± 21.8. The Study group had a mean KSS score of 135.7 ± 19.7 points, while the control group had a score of 134.2 ± 15.7. Between the two groups, there were no statistical differences. The Study group’s KSS functional score was 64.6 ± 8.4, compared to 61.1 ± 7.5 for the control group, yet there was a statistically significant difference between the groups at hospital discharge (P = 0.008). A statistically significant difference in pain level, joint stiffness, and function was also found between the two groups (37.1 ± 12.3 points for the CPM group and 23 ± 14.1 points for the control). Conclusions: From these findings it suggests that CPM has no effect on improving clinical measures. The subjective assessment of pain level, joint stiffness, and functional ability, on the other hand, showed a substantial positive effect.

Fuerza isométrica máxima de cuádriceps e isquiotibiales y funcionalidad luego de la artroplastia total de rodilla / Maximum isometric force of the quadriceps and hamstrings and functionality after total knee arthroplasty

Resumen La gonartrosis es una enfermedad de alta prevalencia en adultos mayores. El objetivo de esta investigación fue identificar los cambios en la fuerza muscular del cuádriceps y su efecto en la funcionalidad de los pacientes operados de artroplastia total de rodilla (ATR) sometidos a kinesiterapia en el Hospital El Carmen de Maipú (HEC). A todos los operados de ATR se les midió, pre y post intervención, fuerza isométrica máxima (FIM), Time Up and Go, test de pararse y sentarse, apoyo unipodal y la escala WOMAC. La FIM de la rodilla operada y la no operada, es mayor en flexión y extensión al comparar ambos géneros (p < 0.0001; p < 0.0001, respectivamente). En el up and go y la prueba pararse y sentarse el rendimiento fue significativamente superior para el género masculino en relación al femenino (p = 0.001; p = 0.007, respectivamente). En el WO MAC, existieron diferencias significativas pre y post intervención en hombres y mujeres (p < 0.0001; p < 0.0001, respectivamente). Los pacientes con un índice de masa corporal (IMC) > 30 kg/m2 tienen 3 veces menos posi bilidades [OR = -3.498; IC (0.062-1.067)] de permanecer en tratamiento en un plazo menor a 50 días. Por otra parte, las lesiones en la rodilla no dominante (izquierda) tiene 4 veces más posibilidades de tratamiento inferior a 50 días [(OR = 2.71; IC (1.000-16.252)]. Existió un aumento de la FIM de la rodilla tratada post intervención, en ambos géneros. La funcionalidad aumentó en hombres y mujeres, posterior a la intervención.

Abstract Gonarthrosis is a highly prevalent disease in older adults. The objective of this re search was to identify changes in quadriceps muscle strength and their impact on the functionality of total knee replacement (TKA) operated patients undergoing kinesitherapy at Hospital El Carmen de Maipú (HEC). All TKA operated patients were measured, pre and post intervention, maximum isometric strength (MIF), Time Up and Go, Standing and sitting test, Unipodal support and the WOMAC scale. The operated and contralateral MIF is higher in flexion and extension when comparing both genders (p < 0.0001; p < 0.0001, respectively). In the up and go and the standing and sitting test, performance was significantly higher for males than for females (p = 0.001; p = 0.007, respectively). In the WOMAC, there were significant differences before and after the intervention in men and women (p < 0.0001; p < 0.0001, respectively). Patients with a body mass index (BMI) > 30 kg/m2 are 3 times less likely [OR = -3.498; CI (0.062-1.067)] to receive treatment in a period of less than 50 days. On the other hand, injuries to the non-dominant (left) knee have a 4 times greater chance of stay in treatment in less than 50 days [(OR = 2.71; CI (1.000-16.252)]. There was an increase in MIF of the knee treated post-intervention, in both genders. Functionality increased in men and women, after the intervention.

Cohorte histórica de artroplastia unicompartimental de rodilla en un hospital universitario chileno / Historical cohort of unicompartmental knee arthroplasty in a Chilean university hospital

OBJETIVO Describir el resultado funcional informado por el paciente de una cohorte de pacientes sometidos a artroplastia unicompartimental de rodilla (AUR) en un hospital universitario chileno. MÉTODOS Se diseñó un estudio de cohorte histórica. Se incluyeron todos los pacientes que se sometieron a AUR de platillo fijo entre 2003 y 2019. Un evaluador independiente se puso en contacto con los pacientes en junio de 2020. Se utilizó el índice de artritis de las universidades de Western Ontario y McMaster (WOMAC) para comparar los procedimientos de AUR (medial o lateral), la edad (mayor o menor de 70 años), y el seguimiento (más o menos de 5 años). RESULTADOS Se incluyeron 78 pacientes, en un total de 94 AURs. La mediana de edad fue de 64 años (rango: 43 a 85 años). Hubo 72 (76,6%) casos de AUR medial. Un paciente necesitó revisión para artroplastia total de rodilla (ATR). Un total de 60 pacientes (76,9%), correspondientes a 72 AURs (76,7%), fueron contactados con éxito por teléfono para el seguimiento final. La mediana del puntaje en los dominios del WOMAC fue: dolor ­ 1 (rango: 0 a 12); rigidez ­ 0 (rango: 0 a 4); y función física ­ 2 (rango: 0 a 29). La mediana del puntaje total en el WOMAC fue de 4 (rango: 0 a 44). Los pacientes sometidos a AUR lateral lograron mejores puntuaciones funcionales (p » 0,0432), y el puntaje total en el WOMAC fue similar en pacientes mayores o menores de 70 años (p » 0,3706). CONCLUSIONES La AUR es un tratamiento eficaz y reproducible para pacientes con artrosis de rodilla unicompartimental. La edad parece no afectar los resultados funcionales, y la AUR es un tratamiento eficaz en pacientes mayores de 70 años. Estos resultados deberían animar a los cirujanos de rodilla a aprender esta técnica y a los responsables de las políticas de salud pública a considerar la AUR para la osteoartritis de rodilla.

PURPOSE To describe the patient-reported functional outcome of a cohort of patients undergoing unicompartmental knee arthroplasty (UKA) in a Chilean university hospital. METHODS A historical cohort study was designed. All patients who underwent fixedbearing UKA between 2003 and 2019 were included. An independent evaluator contacted the patients in June 2020. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) was used to compare UKA procedures (medial or lateral), age (over or under 70 years), and follow up (longer or shorter than 5 years). RESULTS A total of 78 patients, corresponding to 94 UKAs, were included. The median age was 64 years (range: 43 to 85 years). There were 72 (76.6%) cases of medial UKA. One patient needed revision to total knee arthoplasty (TKA). A total of 60 patients (76.9%), corresponding to 72 UKAs, were successfully contacted by phone for the final follow-up. The median scores on the WOMAC domains were: pain ­ 1 (range: 0 to 12); stiffness ­0 (range: 0 to 4); and physical function ­ 2 (range: 0 to 29). The median total score on the WOMAC was 4 (range: 0 to 44). Patients submitted to lateral UKA had better functional scores (p » 0.0432), and the total WOMAC score was similar among patients older or younger than 70 years of age (p » 0.3706). CONCLUSIONS For patients with unicompartmental knee osteoarthritis, UKA is an effective and reproducible treatment. Age does not seem to affect the functional results, and UKA is an effective treatment in patients over 70 years old. These results should encourage knee surgeons to learn this technique and those responsible for public health policies to consider UKA for knee osteoarthritis

Control del dolor con infiltración local transquirúrgica en postoperados de reemplazo total de rodilla / Pain control with local infiltration transsurgical in postoperative total knee replacement

Resumen: Introducción: De 15-20% de los pacientes sometidos a una artroplastía total de rodilla no quedaron satisfechos y las causas más comunes fueron dolor residual y función limitada. De manera tradicional se ha utilizado analgesia epidural o bloqueos nerviosos periféricos como analgesia. Objetivo: Evaluar la eficacia de la infiltración con solución de epinefrina, ketorolaco, morfina y ropivacaína en pacientes postoperados de reemplazo total de rodilla. Material y métodos: Estudio de cohorte observacional, transversal, retrospectivo y analítico. Se incluyeron pacientes con gonartrosis de 18 a 100 años de edad programados para cirugía de reemplazo total de rodilla de Mayo de 2018 a Agosto de 2021, con documentación de sus datos clínicos, demográficos, basales, prequirúrgicos y dolor postoperatorio a las 24 horas. Se compararon pacientes infiltrados con los que recibieron analgesia intravenosa. Resultados: Se incluyeron un total de 66 pacientes con una media de edad de 69.1; 65.2% fueron mujeres. Cuarenta y tres punto nueve por ciento tuvieron afectación del lado izquierdo, 50% tuvieron una clasificación de Kellgren-Lawrence III y 31.8% tuvieron un grado IV. Treinta y seis pacientes (54.5%) formaron el grupo control, mientras que 30 (45.5%) recibieron la intervención con el cóctel analgésico. Con respecto al dolor, se encontró una menor mediana del dolor por escala visual análoga en pacientes con la intervención (2 vs 8 puntos, p < 0.001); la mayoría con el cóctel se encontraron sin dolor (66.7%) o dolor leve (23.3%) y ningún paciente del grupo control lo alcanzó (p < 0.001). Todos los pacientes del grupo control requirieron analgesia de rescate, mientras que sólo en 30% del grupo de intervención se utilizó (p < 0.001). Conclusión: El uso de infiltración local transquirúrgica disminuye el dolor postoperatorio y el requerimiento de analgésicos y analgesia de rescate durante las primeras 24 horas.

Abstract: Introduction: 15-20% of patients undergoing total knee arthroplasty were not satisfied and the most common causes were residual pain and limited function. Epidural analgesia or peripheral nerve blocks have traditionally been used as analgesia. Objective: To evaluate the efficacy of infiltration with epinephrine, ketorolac, morphine and ropivacaine solution in postoperative total knee replacement patients. Material and methods: Observational, cross-sectional, retrospective and analytical cohort study. We included patients with gonarthrosis aged 18 to 100 years scheduled for total knee replacement surgery from May 2018 to August 2021; with documentation of their clinical, demographic, baseline, pre-surgical and postoperative pain data at 24 hours. Infiltrated patients were compared with those receiving intravenous analgesia. Results: A total of 66 patients with a mean age of 69.1 were included;65.2% were women. Forty-three point nine percent had left-sided involvement, 50% had a classification of Kellgren-Lawrence III and 31.8% had a grade IV. Thirty-six patients (54.5%) formed the control group, while 30 (45.5%)received the intervention with the analgesic cocktail. With regard to pain,a lower median pain was found by visual analog scale in patients with the intervention (2 vs 8 points, p < 0.001); most with the cocktail they found no pain (66.7%) or mild pain (23.3%) and no patient in the control group reached it (p < 0.001). All patients of the control group required rescue analgesia, while only 30% of the intervention group used it (p < 0.001). Conclusion: The use of trans-surgical local infiltration decreases postoperative pain and the requirement of analgesics and rescue analgesia during the first 24 hours.

Objective:To explore the nursing effect of enhanced recovery after surgery in total knee arthroplasty under multidisciplinary cooperation.Methods:From January 2017 to May 2020, the clinical data of 102 patients with total knee arthroplasty in First Hospital of Zibo were selected for retrospective analysis. According to the different nursing methods, they were divided into observation group and control group with 51 cases in each group, observation group was given enhanced recovery after surgery under multidisciplinary collaboration, and the control group was given routine nursing care. The length of hospitalization, hospitalization costs, intraoperative blood loss, 24 h postoperative hemoglobin, Visual Analogue Scale (VAS), knee range of motion (ROM), New York Hospital for Special Surgery (HSS) Knee Joint Score and complications were compared between the two groups of patients.Results:In the observation group the length of hospitalization was (7.65 ± 1.21) d, the cost of hospitalization was (92 355.21 ± 352.52) yuan, intraoperative blood loss (224.12 ± 25.32) ml, and 24 h postoperative hemoglobin was (115.12 ± 12.05) g/L,while those were (9.68 ± 2.15) d, (105 423.45 ± 544.25) yuan, (362.12 ± 38.78) ml, (102.32 ± 7.52) g/L in the control group, the difference between the two groups was statistically significant ( t values were 5.88-143.92, all P<0.05). Repeated measures analysis of variance showed that time point, between groups, interactive comparisons of VAS scores, ROM, HSS scores were significantly different between the two groups ( P<0.05). And 12, 48, 72 h after the operation, the VAS scores of the observation group were 4.12 ± 0.35, 2.62 ± 0.21, 1.65 ± 0.12, and 5.62 ± 0.58, 3.85 ± 0.41, 2.85 ± 0.24 in the control group, the difference between the two groups was statistically significant ( t=15.81, 19.07, 31.94, all P<0.05). 1 and 3 months after the operation, the ROM of the observation group were (99.78 ± 12.14)° and (108.95 ± 15.25)°, and the ROM of the control group were (81.65 ± 10.02)° and (98.77 ± 11.08)°, respectively. The difference between the two groups was statistically significant ( t=9.00, 4.22, both P<0.05). Conclusions:To give fast track surgery under multidisciplinary cooperation is beneficial to reduce the amount of bleeding in patients undergoing total knee arthroplasty, shorten the length of hospital stay, and reduce the incidence of complications.

Objective:To understand the current status of perioperative physical prevention of venous thrombosis in patients undergoing total knee and hip replacement and to analyze the barriers to clinical transformation of evidence and improve measures.Methods:Based on the evidence-based continued quality improvement model, then building a team, systematically searching, evaluating and summarizing evidences, establishing review indicators and review methods according to FAME principles (feasibility, appropriately, meanfulness, effectiveness), selecting patients undergoing total knee and hip replacement, nurses, and doctors who underwent total knee and hip replacement surgery from April 30 to August 31, 2020 in Shanxi Provincial People's Hospital as the review objects, and conducting a baseline review according to the review indicators one by one, and analyzing the obstacle factors and improvement measures based on the review results.Results:This study included 29 best evidences, and 17 review indicators were formulated based on the best evidences. Among them, the clinical compliance rate of 5 review indicators were greater than 80%, and the clinical compliance rate of 12 review indicators were less than 80%. The main obstacles were due to the imperfect venous thromboembolism (VTE) risk assessment and management process at the system level, and the low level of knowledge of VTE prevention and management among medical staff at the individual level.Conclusions:This study was based on the best evidences, scientifically and systematically developed clinical review indicators, rigorously and comprehensively analyzed obstacles, and constructed targeted improvement measures, not only for the future physical prevention of perioperative venous thrombosis in patients with total knee and hip replacement surgery transformation provides the basis but also can further promote clinical practice changes and continuous quality improvement.

The Needs of Orthopaedic Patients in Discharge Planning

@#Introduction: Patients' transition from hospital to home could be challenging for patients and caregivers. This is of utmost importance for patients requiring special or long-term care such as post-orthopaedic surgery. Effective discharge planning is required to ensure that patients are prepared to and get continuous care after returning home to prevent complications. Patients' need assessment is essential to develop effective discharge planning to meet the patient's needs. Materials and methods: This mixed-method study aimed to determine the patient's needs to develop a discharge planning for total knee replacement surgery. The needs for 96 total knee replacement patients were assessed using the Needs Evaluation Questionnaire (NEQ). The in-depth interview primary focus was to explore the lived experience of the post-total knee replacement patients receiving care in the hospital. Results: A total of 96 participants (100%) completed the NEQ questionnaire. Most of the needs concerned by the participants were expressed by at least 70% of them except the financial need (59.4%). The semi-structured interview found two elements which were a support group and patients’ needs in terms of emotional, physical and spiritual preparation in developing effective discharge planning. Conclusion: This study clarified that the patient needs assessment in the patient care plan.
