We previously reported the ten to fourteen-year results for 311 Porous Coated Anatomic total hip replacements that had been inserted by two surgeons in 279 patients. The purpose of the present report is to update that study and to report the outcome beyond twenty years. The patients were followed prospectively with clinical assessment with use of the Harris hip score and radiographic analysis, and the results were collected in a database. Two hundred and sixty-eight hips were functioning at the time of death or at the time of the latest follow-up. A total of forty-three hips (14%) underwent major revision for all causes, and an additional four hips underwent minor revision. At a mean of twenty-three years of follow-up, Kaplan-Meier analysis revealed a survival rate of 83% with revision for any reason as the end point. The survival rate was 95% for the femoral component and 88% for the acetabular component with revision for any reason as the end point. The rate of survival of the acetabular component was significantly higher in hips with a 26-mm femoral head than in those with a 32-mm femoral head (91% compared with 80%; p = 0.026).
我们之前报道了两位医生为 279 名患者中的 311 名使用多孔涂层解剖型全髋关节置换患者进行手术的 10 至 14 年的结果。本报告的目的是更新该研究，并报告 20 年以上的结果。通过使用 Harris 髋关节评分和放射学分析对患者进行前瞻性随访，并将结果收集在数据库中。在死亡或最近一次随访时，268 个髋关节仍在使用中。共有 43 个髋关节（14%）因各种原因接受了主要翻修，另外 4 个髋关节接受了次要翻修。在平均 23 年的随访中，Kaplan-Meier 分析显示，以任何原因进行翻修为终点时的生存率为 83%。以任何原因进行翻修为终点时，股骨部件的生存率为 95%，髋臼部件的生存率为 88%。髋臼部件的生存率在使用 26mm 股骨头的髋关节中明显高于使用 32mm 股骨头的髋关节（91%比 80%；p=0.026）。
