摘要
作者应用临床回顾与前瞻性调查的方法，对３４例骨关节病单室胫股关节假体植入失败的病例进行了分析。结果显示造成假体失败的主要原因为：（１）术侧膝关节非植入假体侧胫股关节骨性关节病病变加剧１５例，占４４．１％；（２）膝关节不稳定与假体异常磨损９例，占２６．５％；（３）假体松动７例，占２０．６％；（４）术后深部感染３例，占８．８％。作者认为，这种膝关节假体在形态结构及其固定与稳定方式方面的特性所决定，与绞链式或半绞链式全膝关节假体相比，对患者选择及手术技术要求更为严格。如上述前两类并发症共占本组患者总数的７０％，而导致其发生的主要因素为手术操作不当及适应证欠佳。因此，作者强调在临床应用过程中应对其特别予以重视，以期获得更加满意的疗效。
AbstractWe studied retrospectively and prospectively 34cases of failed knee arthroplasty. The failure wasmostly due to contralateral progressive arthrosis in thetibiofemoral joint(15 cases,44.1%).Instabilization ofthe knee joint and abnormal ranked prothesis second(9cases,26.5%),and loossening third( 7 cases,20.6%). Infections were noted onlv in 3 cases(8.8%). This prothesis demands meticulous surgicaltechniques and strict indications because of its geomet-ric characteristics and stabilization. Contralateral pro-gressive arthrosis and abonormal prothesis accountedfor 70.0%in all, and were resuIted from poor sugicaltechnique and improper indications.
