A review of the results of 192 kinematic total knee replacements five to nine years after the operation showed that the results were still satisfactory. At the time of the review, the ages of the patients ranged from twenty-two to eighty-seven years. About half of the patients had rheumatoid arthritis and the other half, osteoarthrosis. About 90 per cent of the results were rated good or excellent, and the average range of flexion was 109 degrees. Radiolucency was present around 40 per cent of the tibial components, 30 per cent of the femoral components, and 60 per cent of the patellar components, but the lines were thin and not progressive. The complications included loosening of the patellar components in five knees, one fracture of the tibial tray with loosening of the patellar component, one fracture of the patellar component, and one dislocation of the patellar component.
一项对192例全膝关节置换术患者术后五至九年结果的回顾显示，结果仍令人满意。在进行回顾时，患者年龄在22岁至87岁之间。约一半患者患有类风湿性关节炎，另一半患有骨关节炎。约90%的结果被评为良好或优秀，平均屈曲范围为109度。约40%的胫骨假体、30%的股骨假体和60%的髌骨假体周围出现透光线，但这些线很细且无进展。并发症包括5例膝关节髌骨假体松动、1例胫骨托骨折伴髌骨假体松动、1例髌骨假体骨折和1例髌骨假体脱位。
