Objective:To evaluate the effects of peroneal osteotomy combined with arthroscopic knee debridement on perioperative indexes, X-ray indexes, Japanese Orthopaedic Association Assessment score (JOA score), American Hospital for Special Surgery knee score (HSS score) and complication rate of patients with knee osteoarthritis.Methods:A prospective research method was adopted. A total of 110 patients with knee osteoarthritis who were admitted to Chengde Central Hospital from April 2016 to April 2021 were selected as the research objects and divided into the control group (55 cases), the combined group (55 cases) by random number table method. The control group underwent arthroscopic debridement of the knee joint. On the basis of the control group, the combined group was combined with fibula osteotomy. The control group and the combined group were followed up for 6 months after operation. The perioperative indicators, score of JOA before and after 1 month of treatment, X-ray indicators, score of HSS before and after 6 months of treatment, and the incidence of complications during the follow-up period were compared between the control group and the combined group.Results:The operation time of the combined group was longer than that of the control group: (84.36 ± 14.64) min vs. (75.88 ± 12.86) min; compared with before operation, 1 month after operation, the scores of swelling, pain while up and down stairs, walking pain, joint range of motion were increased in the control group and the combined group, and the combined group was higher than the control group: (8.35 ± 0.73) points vs. (6.74 ± 0.67) points, (15.05 ± 1.74) points vs. (13.96±1.66) points, (21.75 ± 2.07) points vs. (18.58 ± 1.73) points, (27.59 ± 3.25) points vs. (25.74 ± 2.83) points; the femoral tibial angle and the range of motion of the knee joint in the control group and the combined group were increased, and the combined group was greater than the control group: (1.94 ± 0.60)° vs. (3.02 ± 0.67)°; the scores of stability, flexion deformity, muscle strength, range of motion, function, and pain in the control group and the combined group increased, and the combined group was higher than the control group: (8.62 ± 0.86) points vs. (6.89 ± 0.78) points, (7.86 ± 0.96) points vs. (6.27 ± 0.68) points, (7.79 ± 0.62) points vs. (6.95 ± 0.57) points, (14.95 ± 2.60) points vs. (12.48 ± 2.33) points, (17.46 ± 2.21) points vs. (14.59 ± 1.76) points, (24.83 ± 3.25) points vs. (18.59 ± 2.57) points, the difference was statistically significant ( P<0.05). During the following up period, there were no significant differences in the incidences of osteofascial compartment syndrome, neurovascular injury, intraarticular adhesion and incision infection between the two groups ( P>0.05). Conclusions:The operation time of fibular osteotomy combined with arthroscopic debridement of knee joint in patients with knee osteoarthritis was longer, but fibular osteotomy combined with arthroscopic debridement of the knee joint can reduce the valgus of the patient and improve the range of motion of the joint. It could effectively reduce the degree of pain and improve the function of knee joint, and the safety was good, with good therapeutic effect.

Arthroscopic fixation of chronic bicruciate tibial avulsion fractures: A case report / 中华创伤杂志(英文版)

A cruciate ligament avulsion is a much less common form of injury than a cruciate ligament tear. Simultaneous tibial avulsion fractures of both cruciate ligaments occur even more rarely. Over the last decades, many studies have described arthroscopic fixation of acute cruciate tibial avulsion fractures, but arthroscopic treatment in a late presenting patient has not been reported in the literature. This case report presents a 32-year-old female with a chronic tibial avulsion fracture of both anterior cruciate ligament and posterior cruciate ligament. Simultaneous fixation of both fractures was performed arthroscopically at week four post-injury. At one year of follow-up, the patient had demonstrated full knee range of motion and stable knee with no complaints, and achieved excellent clinical outcomes. Radiographs showed union of both fractures, and the patient had resumed high-impact exercises.

Progress in arthroscopic surgery for injury of superior labrum anterior posterior of shoulder joint / 中国骨伤

Superior labrum anterior posterior (SLAP) injury is a major challenge for orthopedic surgeons, due to the poor healing ability of the injured labrum. Although arthroscopic surgery is the gold standard for the treatment of SLAP injury, there are still disputes about the adaptation of different surgical techniques, the choice of anchors during operation, knotted or knotless anchors, and fixation methods. The authors believe that arthroscopic repair of SLAP lesions is effective for young patients with intact glenoid labrum(<35 years old) or with extensive activity, where single and knotless anchor is preferred. For the older patients(≥35 years old) with degeneration and wear of glenoid labrum, biceps tenodesis is more preferable, and interference screw fixation technique is recommended. As for patients with failed SLAP repair, biceps tenodesis can achieve a high success rate as a revision surgery. By review of the relevant literature in recent years, this paper summarizes the adaptation of different surgical methods of arthroscopic treatment of SLAP injury, intraoperative anchoring techniques, fixation methods and other improved surgical techniques.

AMR Sign - An Arthroscopic S-shaped Fold Signifying Adequate Medial Meniscus Repair

@#Introduction: The preferred management of medial meniscus tears has notably moved from meniscectomies towards repair. With a higher volume of meniscal repairs being done all across the world with every passing day, the lack of an objective and definitive sign suggesting the adequacy of its repair is daunting. The purpose of our study was to introduce a unique and novel arthroscopic sign formed after adequate repair of the medial meniscus, the AMR (Adequacy of Medial meniscus Repair) sign. We hypothesised that it is not only the objective end point for repair, but can also form the indicator for excellent clinical, functional, and radiological outcome even in the long term. Materials and methods: This was a multicentric, prospective study initiated by the corresponding author, and the findings validated subsequently by the other authors. Overall, it included 804 patients of isolated medial meniscus tear operated with arthroscopic all-inside technique between January 2014 and December 2017. Patients were segregated into three groups based on whether an S-shaped curve in the free, inner edge of the medial meniscus sign was formed post-repair, lost after further tightening, or not formed upon subjective completion of repair. All the patients were followed-up and evaluated based of medial joint line tenderness, McMurray’s test for medial meniscus, IKDC score, WOMET score, and radiologically using an MRI at the terminal follow-up. Results: The mean terminal follow-up was 42.34±4.54 months. There was significant (p<0.01) improvement in all patients at the terminal follow-up post-surgery, irrespective of the group. The group in which AMR sign was formed and maintained showed a significantly better functional outcome on terminal follow-up as well as lower failure rates compared to the other two groups. Conclusion: AMR sign is an S-shaped fold at the inner, free edge of medial meniscus, formed after an adequate repair of isolated medial meniscus tear, as viewed on arthroscopy. It is an objective sign denoting regained integrity of the collagen architecture of the medial meniscus following repair. It is also a reliable indicator of excellent long term functional, clinical, and radiological outcome and also lower failure rates in patients after arthroscopic medial meniscus repair.

Efficacy and safety of ropivacaine combined with alfentanil for analgesia after knee arthroscopic surgery / 中国药房

OBJECTIVE To explore the efficacy and safety of intra-articular injection of ropivacaine combined with alfentanil for postoperative analgesia in patients who underwent knee arthroscopic surgery. METHODS A total of 60 patients who underwent knee arthroscopic surgery were collected from the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture from March to September in 2022， and then divided into trial group and control group with random number table method， with 30 cases in each group. The control group received intra-articular injection of 0.25% ropivacaine 50 mg， and the trial group received intra-articular injection of 0.25% ropivacaine 50 mg+alfentanil 0.15 μg/kg.The first postoperative remedial analgesia time， the total amount of postoperative remedial drugs， numerical rating scale at rest （NRS-R） scores， numerical rating scale at movement （NRS-M） scores， heart rate， mean arterial blood pressure， and pulse oxygen saturation during exercise at different monitoring time points after surgery， the incidence of adverse drug reactions such as hypotension， respiratory depression， nausea， and vomiting after surgery were compared between 2 groups. RESULTS Compared with the control group， the first postoperative remedial analgesia time was significantly longer in the trial group， and the total amount of postoperative remedial drugs was significantly reduced （P＜0.001）. The trial group had lower NRS-R and NRS-M scores at each monitoring time point， with statistically significant differences （P＜0.001）， and there was an interactive effect between time and groups （P＜0.001）. The changes in heart rate， mean arterial blood pressure， and pulse oxygen saturation of patients in the trial group were relatively small， with no statistically significant differences （P＞0.05）， and there was no interactive effect between time and groups （P＞0.05）. There was no statistical significance in the incidence of adverse drug reactions between 2 groups， such as postoperative hypotension， respiratory depression， nausea， vomiting （P＞0.05）. CONCLUSIONS The intra- articular injection of ropivacaine combined with alfentanil shows good efficacy and safety for post-knee arthroscopic analgesia， and significantly prolongs the analgesic duration of ropivacaine.

Fluid preloading before beach chair positioning for arthroscopic shoulder procedures: a randomized controlled trial

Abstract Background and objectives The Beach Chair Position (BCP) has many advantages such as less neurovascular injury and better intra-articular visualization, but it has also negative consequences, including hemodynamic instability. Although maintaining normal Mean Arterial Pressure (MAP) is important, fluid management is also a crucial concept for hemodynamic stability. The main objective of this study is whether preloading before positioning would be effective for less hemodynamic instability. Methods This randomized, controlled study was conducted in a single center in the Istanbul University, Istanbul Faculty of Medicine. Forty-nine patients undergoing elective arthroscopic surgery in the BCP were recruited. In the study group, crystalloid fluid at 10 mL.kg-1 of ideal body weight was administered intravenously 30 min before the BCP for preloading. The primary outcome measures were differences of hemodynamic variables as MAP, Stroke Volume (SV), Heart Rate (HR), and Cardiac Output (CO). The secondary outcome measures were Postoperative Nausea and Vomiting (PONV) rates in postoperative first day, surgical satisfaction scale, total ephedrine dose used during surgery, and total amount of fluid. Results The MAP, CO, and SV measurements of the study group were higher than those of the control group in the 5th minute after the BCP (respectively, p= 0.001, p= 0.016, p= 0.01). The total amount of crystalloid and surgical satisfaction scales were higher in the study group (respectively, p= 0.016, p= 0.001). Total amount of colloid and ephedrine dose used in the intraoperative period, and PONV rates were lower in the study group (p= 0.003, p= 0.018, p= 0.019, respectively). Conclusion Consequently, preloading can be favorable approach to preserve hemodynamic stability.

Comparative Study of Arthroscopic Anterior Cruciate Ligament Reconstruction by Quadrupled Semitendinosus-Gracilis and Tripled Semitendinosus Auto Graft

Background: The anterior cruciate ligament (ACL) is the most frequently disrupted ligament of the knee. Arthroscopic ACL reconstruction is one of the most common orthopaedic procedures now-a-days and has become the gold standard method of treatment in complete ACL tear. Though the choice of graft for ACL reconstruction and the methods of its fixation are matters of debate, hamstring tendon is considered as the favorable graft. Common options for the choice of graft are quadrupled semitendinosus-gracilis and tripled semitendinosus auto graft. Aim of our study is to compare the outcome of arthroscopic ACL reconstruction by quadrupled semitendinosus-gracilis and tripled semitendinosus auto graft.Material & Methods:In this prospective interventional study purposive sampling was done. Sixty patients with complete ACL tear were included in this study from May 2017 to August 2019 at NITOR, strictly considering the inclusion and exclusion criteria. Thirty of them treated with quadrupled semitendinosus-gracilis (group 1) and thirty with tripled semitendinosus (group 2) auto graft. Evaluation by Lysholm knee score was done before and after surgery. Final outcome was evaluated at 24th week post-operatively.Results:Preoperative Lysholm Knee Score was almost similar in group 1 (63.2�1) and in group 2 (63.1�5). This difference was not statistically significant (p=0.582). Postoperative Lysholm Knee Score at 24th week was slightly higher in group 1 (95.0�0) in comparison to group 2 (94.4�2). This difference was also not statistically significant (p=0.361). But excellent functional outcome was more in group 1 (80.0%) in comparison to group 2 (73.3%) whereas no poor or fair outcome was reported in group 1 but fair outcome was reported in 6.7% of patients in group 2. Overall complication rate was 6.67% with no significant intergroup difference.Conclusions:Quadrupled semitendinosus-gracilis auto graft has yielded more excellent results than tripled semitendinosus graft. But as this difference was not significant, it can be said that, both the procedure can be performed for arthroscopic reconstruction of ACL.

The outcomes of posterior cruciate ligament tibial avulsion fixation with a screw using a dual posteromedial portal technique / Desfechos da técnica de portal póstero-medial duplo para fixações de fratura em avulsão tibial do ligamento cruzado posterior

ABSTRACT Objectives Our purpose was to evaluate the clinical results of PCL tibial avulsion fracture fixation performed with 4 mm cancellous screws using a dual posteromedial (PM) portal technique. Methods In a prospective study, we followed 12 patients submitted to PCL tibial insertion avulsion arthroscopic fixation using dual PM portals with cancellous screws from March 2014 to Jan 2020. The proximal higher PM portal served as an instrument portal and provided an optimal trajectory for arthroscopic screw fixation of larger PCL avulsion fractures. The lower PM portal was used as a viewing portal. Results Significant improvements were found between the preoperative and postoperative mean Lysholm scores at six months. The preoperative IKDC score mean of 10.13 increased to 89.3 at the end of six months. Minor adverse results with this technique were: grade I on posterior sag in five knees (41.6%), temporary stiffness in two cases (16.7 %), delayed union in one patient (8.3 %), and difficulty squatting at the end of six months in one patient (8.3%). Temporary extension lag was present in two individuals (16.7%), and fixed subtle flexion deficit of 3-5 degrees occurred in one individual (8.3 %). Conclusion The outcomes obtained with the proposed technique were similar to those obtained with open techniques, although mild flexion deficits and discreet posterior sag may be present in a significant number of cases. Level of Evidence II; Prospective Cohort Study.

Efficacy of mild moxibustion combined with surgery for meniscal injury and its effect on TGF-β1 and PDGF levels in the fluid of knee joint / 针灸推拿医学（英文版）

Objective: To observe the efficacy of mild moxibustion combined with arthroscopic meniscal repair in the treatment of meniscal injury and to explore its action mechanism. Methods: Ninety-eight patients with meniscal injury were divided into a surgery group and a moxibustion plus surgery group by the random number table method, with 49 cases in each group. Both groups received arthroscopic meniscal repair, and the moxibustion plus surgery group was treated with add-on mild moxibustion. The Lysholm score, visual analog scale (VAS) score, and mobility of the affected knee were measured before and after treatment, and transforming growth factor (TGF)-β1 and platelet-derived growth factor (PDGF) levels were measured in the fluid of the affected knee joint. The healing of the meniscus was recorded at a follow-up visit 3 months after the surgery. Results: After treatment, the Lysholm score increased, the VAS score decreased in both groups, and the intra-group differences in both groups were statistically significant (P<0.05). The Lysholm score was higher in the moxibustion plus surgery group than in the surgery group, and the VAS score was lower in the moxibustion plus surgery group than in the surgery group. The differences between groups in both scores were statistically significant (P<0.05). The mobility of the affected knee joint increased in both groups (P<0.05), and it was greater in the moxibustion plus surgery group than in the surgery group (P<0.05). When compared with pretreatment, the levels of TGF-β1 and PDGF in the fluid of the knee joint increased in both groups (P<0.05), and the levels of TGF-β1 and PDGF in the fluid of the affected knee joint were higher in the moxibustion plus surgery group than in the surgery group (P<0.05). The healing of the meniscus in the moxibustion plus surgery group was significantly better than that in the surgery group at the follow-up visit 3 months after the surgery (P<0.05). Conclusion: The effect of mild moxibustion combined with arthroscopic meniscal repair is better than the surgery alone in improving knee function, relieving pain, increasing mobility of the affected knee, and promoting meniscal healing, which may be related to the up-regulation of TGF-β1 and PDGF levels in the fluid of knee joint.

Comparison of interscalene brachial plexus block and superior trunk block with ropivacaine in shoulder arthroscopic surgery / 药学实践杂志

Objective To compare the clinical effects of interscalene brachial plexus block and superior trunk block in arthroscopic shoulder surgery with 0.25% ropivacaine. Methods 46 patients undergoing shoulder arthroscopy surgery were included and randomly divided into group ISB (n=23) and group ST (n=23). Patients in group ISB received 10 ml 0.25% ropivacaine on the lateral side of C5 and C6. Patients in group ST were treated with 5 ml 0.25% ropivacaine on both sides of the superior trunk of brachial plexus. The diaphragmatic excursion, Numerical Rating Scale(NRS), duration of the block, handgrip strength were recorded at different time. Results No statistical difference was detected between the two groups in the reduction of diaphragmatic excursion within 30 min after block (P>0.05). Compared with ISB patients, ST patients had significantly less diaphragmatic excursion at 3 h after block（P<0.05). 30 minutes after block, 8.7% patients in ISB group reached complete HDP and 52.2% patients reached partial HDP. At the same time, no complete HDP and 26.1% partial HDP were detected in ST group. 3 hours after block, patients in ST group had lower complete HDP rate (0.0% vs 17.4%) and lower partial HDP rate (39.1% vs 65.2%) than patients in ISB group. At 30 minutes and 3 h after block, the reduction of grip strength in ST group was significantly lower than that in ISB group (P<0.001). ST group had lower NRS than ISB group (P<0.05). The average block time in ISB group (8.3±1.97 )h was significantly lower than that in ST group (10.9±1.26)h (P<0.01). Conclusion Superior trunk block with 10 ml 0.25% ropivacaine is superior compared to interscalene brachial plexus block in occurrence of HDP, decrease of grip strength, postoperative pain and block duration.

Latarjet procedure for failed arthroscopic Bankart repair: a case report

Arthroscopic Bankart Repair (ABR) provides acceptable results for recurrent anterior shoulder dislocation. However, recent studies have shown recurrent rates of 4-19% or even up to 35-40% in patients aged <25 years, and the results tend to get worse after long-term follow-up. The Latarjet procedure can improve anterior stability by multiple mechanisms, not only can the Bankart lesion be repaired and provide stability, but the transfer of the coracoid process extends the bony articular arc of the glenoid, and the addition of the conjoint tendon may provide dynamic stability as well. The Latarjet procedure for correcting recurrent anterior shoulder dislocation led to good and excellent results in 82.7% of the cases. The Latarjet procedure had the lowest re-dislocation rate, which was significantly lower than the arthroscopic Bankart repair. Latarjet procedure is effective in terms of restoring anteroinferior glenohumeral stability and good option for failed arthroscopic Bankart repair. Recurrence rates of instability are acceptable and re-operation rates were low.

Effectiveness of Intra-Articular Ropivacaine for Post-Operative Analgesia in Arthroscopic Knee Surgeries.

Post-operative pain frequently hampers implementation of day care arthroscopic knee surgery in spite of so many analgesic, local anaesthetic drugs and routes of administration. The aim of this study was to evaluate the efficacy and safety of intraarticularly administered inj. ropivacaine 0.25% 20 ml, after arthroscopic knee surgery performed under spinal anaesthesia, for prolonging the duration of post-operative analgesia.METHODSThis is a prospective randomized study conducted among 80 patients of both sexes, of American Society of Anesthesiologists, physical status I and II, undergoing day care arthroscopic knee surgery who were randomly assigned into two groups (R, C). Group R received 20 ml of 0.25% ropivacaine, whereas group C received 20 ml of 0.9% inj. normal saline through intra-articular route at the end of the procedure. Pain was assessed using visual analog scale (VAS) and paracetamol given as rescue analgesic when VAS >4. Time of first analgesic request and total rescue analgesic were noted.RESULTSTime for the requirement of first post-operative rescue analgesia (255.15±26.35 vs. 92.40±12.54) min and total mean rescue analgesic requirement was (1.32±0.52 vs. 3.0±1.0) in group R and C respectively. Group C had higher mean VAS score throughout the study period. No side effects were found among the groups. These two results were clinically and statistically significant (p<0.05).CONCLUSIONSAdministration of intra-articular inj. ropivacaine 0.25%, 20ml, is effective & safe method of management of postoperative pain in patients undergoing arthroscopic knee surgeries, as it prolongs the duration of postoperative analgesia, provides better quality of analgesia with reduced requirement of rescue analgesia without significant side effects.

Indications and effectiveness of arthroscopic lavage and debridement in osteoarthritis knee

Background: Degenerative joint disease will afflict most of the people if they live long enough. The majority of patients with osteoarthritis present to orthopaedic surgeons seeking relief of pain and associated restoration of function. Various intraarticular and periarticular structures may be the cause of pain. Improvement in osteoarthritis by arthroscopic lavage and debridement is seen due to various mechanisms.Methods: In a prospective study from July 2016 to December 2018, 35 patients with primary osteoarthritis knee were assessed for effectiveness of arthroscopic lavage and debridement in relieving symptoms of osteoarthritis of knee and to determine the indications of arthroscopy in osteoarthritis of knee. Assessment was done using variables as age of the patient, body mass index, varus deformity, radiographic grading and arthroscopic grading.Results: A declining trend was seen on follow up over time; 91.4% excellent to good results seen at one month follow up, 76.1% at six months, 49.93% at twelve months, 37.5%, at eighteen months, 23.07% at twenty-four months and 28.5% at thirty months. Results at six month follow up when compared, were better for age less than 50 years (88.8% Vs 73.1% in >50 years age), normal weight patients with BMI 18.5 to 25(94.5% Vs 58.5% in overweight), varus angulation <100(93.1% Vs 0% in >100), radiological grade I and II (95-100% Vs 45-50% in grade III and IV) and arthroscopic grade I and II (94-100% Vs 0-77% in grade III and IV).Conclusions: Arthroscopic lavage and debridement is an effective method of treatment for osteoarthritis knee in patients with grade I and grade II osteoarthritis having symptoms of pain and locking due to loose bodies or degenerative meniscal tears.

Artroscopía de rodilla bajo bloqueos de nervios femoral y ciático en paciente COVID-19 con artritis séptica. Reporte de caso / Knee arthroscopy under femoral and sciatic nerve blocks in a COVID-19 patient with septic arthritis. A case report

Since the start of the COVID-19 pandemic, several anesthetic societies have generated clinical recommendations for the perioperative management of these patients, including the Chilean Society of Anesthesiology. Among these recommendations, the advantages of regional anesthesia have been highlighted. In this article, we report and discuss the case of a 59-year-old patient with diabetes mellitus II, Chronic Arterial Hypertension, Gout, and Stage IV Chronic Renal Failure admitted with a multifocal septic condition characterized by suppurative collections including a large subcutaneous lumbar abscess recently drained. The patient evolved with left knee septic arthritis and was scheduled for arthroscopic irrigation and debridement. As per protocol a SARS-COV2 PCR was tested and resulted positive. It was decided to proceed to surgery under anesthetic ultrasound-guided femoral and sciatic nerve blocks using an adrenalized (2.5 ug/mL) solution of 0.33% Levobupivacaine- 0.66% Lidocaine (15 mL each). Fifteen minutes later, the knee was mobilized passively without pain. Surgery started after 30 minutes. The surgical and anesthetic conditions were described as adequate by the surgeon and the patient, respectively. The postoperative evolution was satisfactory without presenting respiratory symptoms and the patient was discharged 17 days after under oral antibiotic treatment.

Desde el comienzo de la pandemia de COviD-19, varias sociedades de anestesia han generado recomendaciones clínicas para el tratamiento perioperatorio de estos pacientes, incluida la Sociedad Chilena de Anestesiología. Entre estas recomendaciones, se han destacado las ventajas de la anestesia regional. En este artículo, reportamos y discutimos el caso de un paciente de 59 años con diabetes mellitus tipo 2, hipertensión arterial, gota e insuficiencia renal crónica en etapa IV, admitido por una sepsis multifocal caracterizada por colecciones supurativas que incluyen un gran absceso lumbar subcutáneo drenado recientemente. El paciente evolucionó con artritis séptica de rodilla requiriendo de una exploración y aseo artroscópico. Por protocolo perioperatorio COviD-19, se solicitó PCR para SARS-COv2 con un resultado positivo. Se decidió proceder a la cirugía bajo bloqueos anestésicos guiados por ultrasonido de nervios femoral y ciático utilizando una solución adrenalizada (2,5 ug/mL) de levobupivacaína al 0,33% lidocaína al 0,66% (15 mL en cada uno). Quince minutos después, la rodilla se movilizó pasivamente sin dolor. La cirugía se inició tras media hora empleando una ligera sedación con propofol. Las condiciones quirúrgicas y anestésicas fueron descritas como adecuadas por el cirujano y el paciente. Este último evolucionó favorablemente, sin síntomas respiratorios y fue dado de alta 17 días después con tratamiento antibiótico oral.

Reparación transtibial de la raíz posterior del menisco lateral en lesiones agudas: técnica quirúrgica y seguimiento clínico a corto plazo / Transtibial repair of posterior root of the lateral meniscus in acute lesions: surgical technique and short-term clinical follow-up

Introducción Las lesiones de la raíz posterior del menisco lateral (RPML) afectan la transferencia de la carga axial de la rodilla, lo cual genera una sobrecarga con el posterior deterioro del cartílago articular. Se han descrito numerosas técnicas quirúrgicas en la literatura para su tratamiento, pero aún no se ha demostrado superioridad de alguna, por ende, existen controversias sobre cual técnica es la más indicada para estas lesiones. El objetivo del estudio es describir la técnica quirúrgica y la evolución clínica de pacientes intervenidos con fijación transtibial de la RPML en una clínica especializada, durante el periodo 2016-2017. Materiales & Métodos Se realizó una descripción de la técnica quirúrgica y una serie de casos retrospectiva. Se incluyeron pacientes con lesiones agudas en la RPML, los cuales fueron intervenidos quirúrgicamente utilizando una nueva variación a técnica transtibial. Para determinar la evolución cínica de los pacientes se realizaron las escalas Lysholm e IKDC, antes y después de la cirugía. Resultados Se intervinieron seis pacientes con lesión aguda de la RPML, cuatro de sexo masculino. El tiempo entre el trauma y la cirugía fue en promedio 2,5 meses. Todos los pacientes presentaron lesión concomitante de ligamento cruzado anterior. Al comparar el estado inicial de los pacientes y el postoperatorio mediante las escalas de Lysholm e IKDC, se encontraron diferencias estadísticamente significativas (p<0,05). Asimismo, no se realizaron reintervenciones durante el seguimiento. Discusión La reparación de la RPML con la nueva variación de la fijación transtibial proporciona una mejoría en la función, el dolor y el nivel de actividad de los pacientes, lo que puede ayudar a retrasar la progresión de la osteoartrosis en la rodilla. Igualmente, este procedimiento se puede realizar de forma segura aún en casos de lesiones ligamentarías concomitantes. Nivel de evidencia: IV

Background injuries of posterior lateral meniscus root (PLMR) affect the transfer of the axial load of the knee. Several surgical techniques have been described for it treatment, but still none has demonstrated superiority. Consequently, there are controversies about which technique is most indicated for these injuries. The aim is to describe the a surgical technique and the clinical follow up of patients operated with transtibial fixation of PLMR in a specialized clinic, during the 2016-2017. Methods Retrospective case series and description of the surgical technique. We included patients with acute injuries in the PLMR, who were operated using a new variation to the transtibial technique. For the clinical follow-up, the IKDC and Lysholm scores were performed before and after surgery. Results Six patients with acute lesion in the PLMR were intervened, four were male. The time between trauma and surgery was on average 2.5 months. All the patients presented a concomitant lesion of the anterior cruciate ligament. When comparing the initial state of the patients and the postoperative period, statistically significant differences were found (p <0.05). Likewise, reinterventions were not performed during follow-up. Discussion The repair of PLMR with the new variation of the transtibial fixation provides an improvement in the function, the pain and the level of activity of the patients, which can help to delay the progression of osteoarthrosis in the knee. Likewise, this technique can be performed safely even in cases of concomitant ligament injuries. Level of clinical evidence: Level IV

Arthroscopic technique with fiber tape circular fixation for treating avulsion fracture of tibial insertion of anterior cruciate ligament / 中国组织工程研究

BACKGROUND: The avulsion fracture of tibial Insertion of anterior cruciate ligament needs to be operated and fixed as early as possible. At present, the open reduction (absorbable screw, hollow screw, steel wire, and titanium cable) Is commonly used in the clinical treatment plan for internal fixation, which is more traumatic and has many postoperative complications. Arthroscopic reduction and elastic (suture) Internal fixation of anterior cruciate ligament fracture has the advantages of minimally invasive, clear surgical field, high fixation accuracy, few complications, good fracture reduction and healing, meeting the biomechanical requirements, and allowing rapid recovery of joint function, but also has the disadvantages of Insufficient strength, and osteotomy. OBJECTIVE: To compare the treatment efficacy of arthroscopic technique with Fiber Tape circular fixation and open reduction and fixation for the avulsion fracture of tibial Insertion of anterior cruciate ligament. METHODS: Thirty-two patients with tibial eminence fracture at Department of Orthopedics of Shanghai China Metallurgical Hospital from January 2017 to December 2018 were enrolled. All patients signed the informed consents and the study was approved by the Ethics Committee. The patients were divided into two groups based on surgical methods: Minimally Invasive group (n=17, arthroscopic reduction and Fiber Tape circular fixation) and open group (n=15, open reduction and hollow tension screw fixation). The operation time, blood loss, and postoperative complications were recorded. The range of motion of knee joint, Lysholm score, and International Knee Documenting Committee score before operation, 1 and 6 months after surgery were recorded. X-ray film was used to evaluate fracture healing. RESULTS AND CONCLUSION: (1) All patients were followed up for 6-13 months. (2) There were no significant differences in age composition, fracture type, cause of injury or preoperative score between two groups. (3) X-ray film showed satisfactory fracture reduction after operation. There were no neurological, vascular injury or fracture displacement after surgery. The fractures healed well after 6 months. (4) There was no significant difference In the operation time and postoperative complications between two groups. The blood loss showed significant difference between two groups (P=0.036). (5) The range of motion of knee joint at postoperative 1 month In both groups was significantly larger than that at baseline (P < 0.05). The range of motion of knee joint at postoperative 6 months was significantly larger than that at postoperative 1 month (P < 0.05). The range of motion of knee joint at postoperative 1 and 6 months in the minimally invasive group was significantly larger than that in the open group (P < 0.05). (6) The Lysholm and International Knee Documenting Committee scores at postoperative 1 month in both groups were significantly higher than those at baseline (P < 0.05). The scores at postoperative 6 months were significantly higher than those at postoperative 1 month (P < 0.05). The scores at postoperative 1 and 6 months in the minimally invasive group were significantly higher than those in the open group (P < 0.05). (7) These findings suggest that the patients in both groups after undergoing surgical methods had restored motion of range with time going. Compared with open fixation, arthroscopic reduction and Fiber Tape circular fixation for treating tibial eminence fracture has less blood loss, less trauma, shorter recovery time and higher functional recovery.
