人工全膝关节置换术治疗膝关节骨关节炎

目的]评价人工膝关节置换术治疗骨关节炎的临床疗效。方法]本院自1994年10月～2003年10月采用人工全膝关节置换术治疗膝关节骨关节炎81例（95膝），男10例，女71例；平均年龄65．5岁（50—82岁）；左膝35例，右膝26例，双侧同时置换17例；保留后交叉韧带假体18膝，后方稳定性假体62膝，活动衬垫15膝。结果]本组平均随访42个月（14—108个月），应用HSS膝关节评分系统进行分析，优：80膝（84．21％），良：10膝（10．53％），可：3膝（3．16％），差：2膝（2．10％）。优良率94．74％。结论]作者认为人工全膝关节置换术能有效的缓解膝关节骨关节炎的疼痛，改善膝关节功能。正确的选择假体、精细的手术操作和严格的术后康复是保证手术效果的关键。

Total knee replacement for osteoarthritis of knee joint

Objective]To estimate the results of the total knee replacement for osteoarthritis knee joint.Method]Eighty-one patients(95 knees)with osteoarthritis of knee joint were selected for total knee replacement.The average age of the patients was 65.5 years with a range of 50~82 years,which involved 10 males and 71 females.Left knee was in 35 cases and right knee was in 26 cases.Bilateral knee replacement one time was 17 cases.The posterior crnciate ligament retaining prosthesis was 18 knees,posterior stabilizing prosthesis was 62 knees and mobile bearing prosthesis was 15 knees.Result]All the patients were available at the follow-up,with a mean of 42 months(14~108 months).According to HSS system,80 knees(84.21%)had an excellent results;10 knees(10.53%),a good result;3 knees(2.86%),a fair result;and 2 knees(1.9%),poor result.The satisfactory rate was 95.23%.Conclusion]Total knee replacement can decrease knee pain and improve knee function.The prosthesis choice,surgical technique and postoperative rehabilitation are key factors to the operation results.
