Five- to 10-year follow-up was obtained on a series of total articular replacement arthroplasties performed at a single university-affiliated teaching hospital. Eighty arthroplasties were performed on 64 patients. Twelve patients (accounting for 14 hip arthroplasties) died. Follow-up was obtained on 62 of the 66 remaining hips (94%). Thirty-five hips had been revised (56%), 32 for acetabular loosening and 3 for femoral loosening, 1 of which led to femoral stem fracture. The average time to revision was 72 months (22 to 132 months). The revision procedures were extensive in terms of operative time, blood loss, and necessity of acetabular bone grafting. Follow-up of the 27 that had not been revised averaged 84 months and revealed 1 hip excellent, 5 good, 1 fair, and 20 poor results. The overall clinical failure rate (revisions plus clinically poor results) was 89% (55/62 hips). These results are far inferior to conventional total hip replacement, and the extent of the revision procedures indicates that this is not a conservative alternative to conventional total hip replacement.
对一所大学附属医院进行的一系列全关节置换成形术患者进行了5至10年的随访。对64例患者实施了80例关节成形术。12例患者（占14例髋关节置换术）死亡。对其余66个髋关节中的62个（94%）进行了随访。35个髋关节进行了翻修（56%），其中32个是因为髋臼松动，3个是因为股骨松动，其中1例导致股骨干骨折。翻修的平均时间为72个月（22至132个月）。翻修手术在手术时间、失血量和髋臼植骨必要性方面都较为复杂。未进行翻修的27个髋关节平均随访84个月，结果显示1个髋关节为优，5个为良，1个为中，20个为差。总体临床失败率（翻修加上临床效果差）为89%（55/62个髋关节）。这些结果远低于传统全髋关节置换术，而且翻修手术的复杂程度表明这并非传统全髋关节置换术的保守替代方案。
