From a series of 135 patients (146 prostheses) who had had primary hip replacement in 1975 and 1976 we reported the outcome at ten years in 83 surviving patients in 1988 and that at 15 years in 44 surviving patients in 1994. Now, 22 years after the operation, we have reviewed the 21 patients who are still alive. Nineteen (20 hips) of these 21 patients (22 hips) with a mean age of 85.7 years still had their original prosthesis. Most patients were satisfied with the result, although the level of activity in many was reduced because of increasing age and other medical problems. The stem was stable in all 20 hips. Only one cup was definitely loose. Wear was observed in 40% of the cups but this was not a clinical problem. At the 22-year follow-up the cumulative survival rate of the prosthesis was 85%, of the stem 91% and of the cup 88%. Since 1975, 11 (7.5%) of the original 146 prostheses have been revised.
我们对1975年和1976年接受初次髋关节置换的135例患者（146个假体）进行了研究，于1988年报告了83例存活患者的10年随访结果，并于1994年报告了44例存活患者的15年随访结果。如今，手术22年后，我们对仍存活的21例患者进行了复查。这21例患者（22个髋关节）平均年龄85.7岁，其中19例（20个髋关节）仍保留最初植入的假体。尽管多数患者因年龄增长和其他健康问题活动水平有所下降，但他们对结果大多感到满意。所有20个髋关节的股骨柄均稳定。仅有一个髋臼杯明显松动。40%的髋臼杯出现磨损，但这未构成临床问题。在22年随访时，假体的累积生存率为85%，股骨柄为91%，髋臼杯为88%。自1975年以来，最初的146个假体中有11个（7.5%）进行了翻修。
