Effects of Modified Sanhuang Powder （加味三黄散） Combined with Cold Compression on Swelling and Pain after Knee Arthroscopy： A Retrospective Cohort Study / 中医杂志

ObjectiveTo compare the effects of topical application of Modified Sanhuang Powder （加味三黄散， MSP） combined with cold compression versus cold compression alone on swelling and pain after knee arthroscopy through a retrospective cohort study. MethodsMedical records of 134 patients with knee arthroscopy-induced knee swelling and pain were divided into non-exposure group （51 cases） and exposure group （83 cases） based on whether they used MSP for external application after surgery. The non-exposure group received simple cold compression therapy in addition to functional exercise and routine treatment after surgery， while the exposure group received topical MSP on the basis of what were given in the non-exposure group. The Visual Analog Scale （VAS） scores were compared between the two groups before and 7 days after treatment， and knee swelling measurements were taken before and 3， 5， and 7 days after treatment. The clinical effective rate was compared between the two groups. ResultsThe VAS scores in both groups were lower after treatment （P＜0.05）， and the exposure group had lower scores than the non-exposure group （P＜0.05）. On the 3rd， 5th， and 7th days of treatment， the scores on swelling at 2 cm above the superior pole of the patella， at the midline of the patella， and 5 cm below the inferior pole of the patella significantly decreased after treatment in both groups （P＜0.05）， and the exposure group had lower scores than the non-exposure group （P＜0.05）. The total clinical effective rate in the exposure group was 91.56% （76/83）， which was higher than 78.43% （40/51） in the non-exposure group （P＜0.05）. ConclusionTopical application of MSP combined with cold compression is effective in relieving postoperative swelling and pain after knee arthroscopy and is superior to cold compress alone.

Knee subchondroplasty for management of subchondral bone cysts: a novel treatment method

Knee subchondroplasty (SCP) is one of the most novel minimally invasive methods for treating bone marrow lesions. The literature suggests that it is safe, with few complications and good outcomes. However, no studies have documented its usage for managing large subchondral bone cysts. This article outlines a case report and details the pearls and pitfalls of SCP in treating large subchondral bone cysts. Our patient underwent arthroscopic debridement with medial femoral condyle SCP. Mild posterior extravasation of synthetic bone substitute was observed on Postoperative Day 1, which was immediately rectified on revision arthroscopy. Gradual escalation of weight bearing and good pain relief were subsequently achieved, and the patient has remained complication-free after two years. No further extravasation were observed on repeat radiography. SCP is a feasible temporising measure that may help to delay the need for bone allograft or immediate knee arthroplasty in younger patients while retaining function and delaying loss of productivity.

Clinical application of enhanced recovery after surgery in the perioperative period of anterior cruciate ligament reconstruction / 中国组织工程研究

BACKGROUND: Anterior cruciate ligament injury, with an increasing incidence in recent years, will seriously impact the motor function of the knee joint. Rehabilitation exercise after anterior cruciate ligament reconstruction is directly related to whether the patient can obtain ideal joint function. It is of important clinical significance to introduce the concept of enhanced recovery after surgery (ERAS) into the perioperative management of arthroscopic anterior cruciate ligament reconstruction. OBJECTIVE: To explore the clinical effect of ERAS in the perioperative period of anterior cruciate ligament reconstruction. METHODS: Sixty patients with anterior cruciate ligament injury, who were treated in the Department of Orthopedics, Renmin Hospital of Wuhan University from July 2016 to July 2018, were randomly divided into ERAS group (n=30) and traditional treatment group (n=30). Postoperative Visual Analogue Scale score, recovery time of knee range of motion, Lysholm knee scoring scale score, hospitalization duration, patients’ satisfaction rating were compared between the two groups. The implementation of the study complied with the Declaration of Helsinki and the relevant ethical requirements of Wuhan University Renmin Hospital, and all the enrolled patients were fully informed of the trial process. RESULTS AND CONCLUSION: The Visual Analogue Scale scores in the ERAS group were significantly lower than those in the traditional treatment group at 1, 24 hours, 2, 3, and 7 days after surgery (P < 0.05). The time that the range of motion returned to 30°, 60°, 90° and 120° after surgery in the ERAS group was significantly less than that in the traditional treatment group (P < 0.05). The Lysholm knee scoring scale scores in 3 months and 6 months after surgery in the ERAS group were significantly higher than those in the traditional treatment group (P < 0.05). The length of hospitalization in the ERAS group was significantly lower than that in the traditional treatment group (P < 0.05). The patients’ satisfaction rating in the ERAS group was significantly higher than that in the traditional treatment group (P < 0.05). To conclude, the introduction of ERAS concept into the perioperative management of anterior cruciate ligament reconstruction has obvious merits in reducing anxiety, relieving postoperative pain, reducing postoperative complications, promoting early recovery of patients and accelerating the recovery of knee joint function.

Effects of intraarticular tramadol, magnesium and ketamine on postoperative pain in arthroscopic meniscectomy / Efeitos de tramadol, magnésio e cetamina por via intra-articular sobre a dor pós-operatória em meniscectomia artroscópica

Abstract Objective: Postoperative pain control is important in terms of early recovery and rehabilitation in arthroscopic meniscectomy. For this purpose, we aimed to compare the effects of intraarticular tramadol, magnesium, and ketamine with combinations of pericapsular bupivacaine on postoperative pain and recovery in arthroscopic meniscectomy. Methods: Ninety patients who underwent arthroscopic meniscectomy were enrolled in the study. Group T was given tramadol, Group K was given ketamine, and Group M was given magnesium reconstituted intraarticularly, and all groups received periarticular bupivacaine. Comparisons were made in terms of the patients' postoperative Visual Analogue Scale scores with and without movement, need for additional analgesics, first analgesic time, mobilization times, adverse effects, and satisfaction with the analgesics. Results: The Visual Analogue Scale scores were lowest in Group T at 0 minutes, and were higher in the 15th and 30th minutes and 1st, 2nd, and 6th hours. Visual Analogue Scale values with movement were found to be high in Group M at 0 and 15 minutes, but they were found to be higher in group T in the 30th minute, 1st, 2nd and 6th hour. The groups were similar in terms of postoperative additional analgesic use, number of analgesic use, and satisfaction with analgesics; however, the first analgesic time was earlier in Group M, and the first mobilization time was earlier in Group K. Conclusion: Intraarticular ketamine enables early mobilization and less need for additional analgesics, it also provides a better analgesic effect in comparison with intraarticular tramadol and magnesium.

Resumo Objetivo: O controle da dor pós-operatória é importante para recuperação e reabilitação precoces em meniscectomia artroscópica. Portanto, nosso objetivo foi comparar os efeitos de tramadol, magnésio e cetamina administrados por via intra-articular em associação com bupivacaína pericapsular sobre a dor e a recuperação após meniscectomia artroscópica. Métodos: Noventa pacientes submetidos à meniscectomia artroscópica foram incluídos no estudo. O Grupo T recebeu tramadol, o Grupo K recebeu cetamina e o Grupo M recebeu magnésio em doses reconstituídas por via intra-articular e todos os grupos receberam bupivacaína por via periarticular. As avaliações foram feitas mediante comparação dos escores em escala visual analógica no pós-operatório dos pacientes em movimento e em repouso, necessidade de analgésicos adicionais, tempo até a primeira necessidade de analgésico, tempo de mobilização, efeitos adversos e satisfação com os analgésicos. Resultados: Os escores da escala visual analógica foram menores no minuto zero e maiores nos minutos 15 e 30 e nas horas 1, 2 e 6 no Grupo T. Os escores da escala visual analógica em movimento foram maiores nos minutos zero e 15 no Grupo M e maiores no minuto 30 e nas horas 1, 2 e 6 no Grupo T. Os escores dos grupos foram semelhantes em relação à necessidade de analgésico adicional no pós-operatório, ao consumo de analgésico e à satisfação com os analgésicos, mas os tempos até a primeira necessidade de analgesia e até a primeira mobilização foram mais curtos nos grupos M e K, respectivamente. Conclusão: A administração intra-articular de cetamina permite mobilização precoce e diminui a necessidade de analgésicos adicionais, além de proporcionar um melhor efeito analgésico em comparação com tramadol e magnésio por via intra-articular.

Objective To observe the minimum effective local anesthetic dose of intra-articular ropivacaine with dexmedetomidine for analgesia after knee arthroscopy in patients.Methods Seventy-two patients (35 males,37 females,aged 60-75 years,ASA grade Ⅰ or Ⅱ)undergoing knee arthro-scopy under total intravenous anesthesia were randomly divided into two groups (n =36 each):ropiv-acaine group (group R)and ropivacaine with dexmedetomidine group (group DR);Ropivacaine was injected intra-articularly in group C,and dexmedetomidine 1 μg/kg with ropivacaine was injected intra-articularly in group DR.ED50 of ropivacaine was determined by the sequence method.VAS score3 two hours after operation was rated as effective.The initial dose was 3 mg and according to the effective or ineffective results in previous patient,a dose of ropivacaine was decreased or increased 1.1 times to the previous patient.BP,HR,VAS Score,and OAA/S score were recorded five minutes preoperatively(T0 ),1 h (T1 ),2 h (T2 ),3 h (T3 ),6 h (T4 ),12 h (T5 ),24 h (T6 ),and 48 h (T7 ) after operation in two groups.Results There was no significant difference between the two groups with regard to the BP,HR,VAS Score,and OAA/S score.ED50 of ropivacaine for analgesia after knee arthroscopy was 0.31% (95%CI 0.30%-0.32%),and ED50 of ropivacaine with dexmedetomi-dine for analgesia after knee arthroscopy was 0.14% (95% CI 0.14%-0.1 5%). Conclusion Intra-articular administration of ropivacaine with dexmedetomidine could provide superior postoperative analgesia.The dose of ropivacaine for analgesia after knee arthroscopy should be reduced when combined with dexmedetomidine in patients.

Anestesia raquidea versus anestesia intrarticular en cirugia artroscopica de rodilla / Spinal anesthesia versus intra-articular anesthesia in arthroscopic surgery of the knee

Introducción: La artroscopia de rodilla es el procedimiento quirúrgico más común para tratar pacientes con lesiones meniscales o condrales. El objetivo de este trabajo fue comparar la eficacia de la anestesia raquídea versus la intrarticular en artroscopias simples de rodilla, evaluar la calidad de la anestesia, describir la incidencia de los efectos adversos y determinar las complicaciones en ambos casos. Materiales y Métodos: Estudio prospectivo, aleatorizado para comparar dos procedimientos anestésicos mediante la evaluación de la edad, el tiempo de cirugía, la duración de la anestesia, el tiempo de internación, el dolor, la conformidad con el procedimiento y los costos. Se utilizó el test t de Student para las estadísticas y probabilidades. Nivel de significación: p <0,05. Resultados: Se incluyó a 70 pacientes, 35 fueron operados con anestesia intrarticular y 35, con anestesia raquídea. El tiempo de internación fue mayor en el grupo de anestesia raquídea (7.34 h; rango 4-11) que en el grupo de anestesia intrarticular (3.43 h; rango 2-5), p <0,0001. En la variable costo, hubo una diferencia significativa a favor de la anestesia intrarticular con respecto a la anestesia raquídea (p <0,0001). Conclusión: Las ventajas encontradas a favor de la anestesia intrarticular fueron: estadías hospitalarias acortadas, se evitaron efectos indeseables de la anestesia raquídea (bloqueo motor, náuseas, vómitos, hipotensión, pérdida transitoria de esfínter urinario y retención urinaria [globo vesical]); disminución de los costos y mayor aceptación de los pacientes.

Introduction: Knee arthroscopy is the most common surgical procedure to treat patients with meniscal and/or chondral injuries. The aim of this study was to compare the efficacy of spinal vs. intra-articular anesthesia in knee arthroscopy, to assess the quality of anesthesia, to describe the incidence of adverse effects and to determine the complications in both cases. Methods: Prospective, randomized study to compare two anesthetic procedures evaluating age, duration of surgery, duration of anesthesia, length of hospitalization, pain, patient satisfaction and costs. Student t test was used for statistics and probabilities. Level of significance: p <0.05. Results: Seventy patients were included, 35 were operated on under intra-articular anesthesia and 35 received spinal anesthesia. Hospital stay was longer in the spinal anesthesia group (7.34 hours; range 4-11) than in the other group (3.43 hours; range 2-5, [p <0.0001]). The cost variable showed a significant difference in favour of intra-articular anesthesia compared to spinal anesthesia (p <0.0001). Conclusion: The advantages found in favour of intra-articular anesthesia were: shortened hospital stays, avoidance of the undesirable effects of spinal anesthesia (motor block, nausea, vomiting, hypotension, transient loss of urinary sphincter and urinary retention [distended bladder]), reduced costs and increased patient acceptance.

Operative cooperation of arthroscopic reconstruction of anterior cruciate ligament and posterior ligament with autologous tendons / 现代临床护理

Objective To summarize the operative effect and nursing experience of arthroscopic reconstruction of anterior cruciate ligament (ACL) and posterior ligament (PCL) with autologous tendons. Methods Eleven patients with both ACL and PCL were treated with surgical operation by arthroscopic reconstruction of anterior cruciate ligament and posterior ligament with autologous tendons. Before operation, supplies of surgical articles, mastery of the instrument's properties, procedures, connection mode and precautions were well performed. During the operation, the nursing measure covered also accurate, skilled and agile cooperation. Results The operation was successfully completed, with the average time of (2.7 ± 0.2)h, bleed volume of (32.0 ± 9.8)mL. No infections occurred after surgery. The Lysholm score after operation was higher than that before operation (92.6 ± 3.2 vs. 65.5 ± 3.1;P<0.01). Conclusion Arthroscopic reconstruction of anterior cruciate ligament and posterior ligament with autologous tendons has good clinical therapeutic effect. Preoperative well preparation and expertly operative cooperation are critical for the success of surgery.

Observation on analgesic effects of intra-arecular ropivacaine with fentanyl after knee arthroscopy / 中国基层医药

ObjectiveTo observe the difference in analgesia effects of ropivacaine with fentanyl used intraarticularly after the single knee arthroscopy procedure.Methods40 patients performed knee arthroscopy under combined spinal-epidural anaesthesia( CSEA),were randomly divided into 4 groups (n =10),at the end of operation 10mlof different drug at the group F,R,FR and N(fentanyl 10μg,0.5％ ropivacaine,fentanyl 10μg +0.5％ ropivacaine,normal saline)were injected intra-articularly.The antalgic effects of four groups based on standard of VAS were observed at the 2,4,8,12 and 24h after operation.ResultsThe 2h postoperative VAS scores were lower in four groups,the differences in four groups were not significant.The 4,8,12,24h postoperative VAS scores of F,R and FR group were much lower than that of N group ( all P ＜ 0.05 ).Moreover,VAS scores of FR group were much lower than that of F and R group( all P ＜ 0.05 ).No other adverse effects were observed.ConclusionIntra-articular administration of ropivacaine with fentanyl could provide superior postoperative analgesia without side effects.It was an excellent regimen for analgesia after knee arthroscopy.

Analgesia intraarticular posoperatoria en cirugía artroscópica de rodilla / Postoperative intraarticular analgesia in arthroscopic knee surgery

Se realizó un estudio descriptivo y transversal de 100 pacientes que acudieron a la consulta especializada de artroscopia de la rodilla del Hospital Clinicoquirúrgico Docente Dr Joaquín Castillo Duany de Santiago de Cuba (enero de 2007-diciembre del 2008), a fin de evaluar la efectividad de la inyección intraarticular de bupivacaína al 0,25 por ciento como método analgésico, antes de comenzar la cirugía o después de finalizarla. Los integrantes de la casuística se distribuyeron en 2 grupos de igual número; a los de un grupo se les administraron 30 mL de bupivacaína con epinefrina, 20 minutos previos a la operación, y a los del otro se les aplicó lo mismo, pero al concluir la intervención. Quedó demostrada la efectividad de la citada inyección después de la artroscopia, pues redujo la intensidad del dolor posoperatorio y el consumo de analgésicos con un mínimo de complicaciones; en cambio, su uso preventivo no fue efectivo

A cross-sectional and descriptive study was carried out in 100 patients attending the specialized outpatient department of knee arthroscopy at Dr Joaquín Castillo Duany Teaching Clinical Surgical Hospital of Santiago de Cuba (January 2007-December 2008) to evaluate the effectiveness of 0,25 per cent bupivacaine intraarticular injection as analgesic method before or after surgery. Patients of the case material were distributed in 2 equal groups; one group received 30 mL of bupivacaine with epinephrine 20 minutes before surgery, and the other received the same but after the intervention. The effectiveness of this injection was demonstrated after the arthroscopy as it reduced intensity of the postoperative pain and the use of analgesics with minimal complications; however their preventive use was not effective

Arthroscopic reconstruction of posterior cruciate ligament with quadriceps tendon fixed by a patellar block and an allograft bone plug / 中华创伤骨科杂志

Objective To discuss the design of arthroscopic reconstruction of posterior cruciate ligament (PCL) with quadriceps tendon fixed by a patellar block and an allograft bone plug, and its clinical outcome. Methods Thirteen patients suffering from PCL injury were treated by the technique mentioned above. The connection between quadriceps tendon and superior patellar pole was preserved in the harvest process of quadriceps tendon. The femoral tunnel was made like a bottle neck, which was clogged with the patellar bone block. The quadriceps tendon strip was fixed by an allograft bone plug pressed into the tibial tunnel. Their functional recovery was evaluated by Lysholm scoring and IKDC(International Knee Documentation Committee) criteria. Results In the average follow-up period of 19 months, there were not any severe nerve or blood vessel lesions, or failures of transplanted ligament None of the patient complained of knee instability after the operation. The pain was relieved in most patients, but three complained of pain after knee movement A little calcification was found in the quadriceps tendon at the superior patellar pole one year after the operation in the X-ray of a patient There was significant difference in Lysholm scale between pre-operation and post-operation (P
