The assessment of patients following prosthetic knee replacement suffers from a lack of objective criteria. An automated method of laboratory assessment that permits the objective evaluation of knee joint function is described. Nine biomechanical parameters were statistically selected, weighted, and combined to develop a Performance Index (Ip). One hundred ninety-two patients (274 diseased knees) were studied prior to total knee replacement surgery, with 107 patients (138 knees) returning for a 1-year postoperative study. Preoperative rheumatoid knees were found to have significantly poorer function than those involved with degenerative disease. Overall, the patients experienced a marked improvement 1 year post-total knee replacement (TKR), with their functional scores approaching the lower limits of normal. Prostheses were assessed according to generic classes as well as specific design types. The newer generation devices were found to produce better functional results. In the patients receiving Anametric and Total Condylar total knee devices, a patellar resurfacing component was found to produce improved knee function in comparison with patients receiving the same prosthesis but without patellar resurfacing.
人工膝关节置换术后患者的评估缺乏客观标准。本文描述了一种实验室自动化评估方法，可对膝关节功能进行客观评价。从统计学角度选取、加权并组合九个生物力学参数，以建立一个性能指数（Ip）。在全膝关节置换手术前对192例患者（274个患病膝关节）进行了研究，其中107例患者（138个膝关节）术后1年返回进行复查。结果发现，术前类风湿性膝关节的功能明显比退行性疾病相关膝关节的功能差。总体而言，患者在全膝关节置换（TKR）术后1年有显著改善，其功能评分接近正常下限。根据通用类别以及特定设计类型对假体进行了评估。结果发现，新一代装置产生了更好的功能效果。在接受Anametric和全髁型全膝关节装置的患者中，与接受相同假体但未进行髌骨表面置换的患者相比，发现髌骨表面置换组件可改善膝关节功能。
