The purpose of the present study was to evaluate the long-term outcome of the unrevised part in one-component total hip arthroplasty revision (index operation). Forty-four patients (46 hips) with a mean age of 58years at the time of the index operation were included. At the final follow-up, 4 of the 19 (21%) unrevised acetabular components and 6 of the 27 (22%) unrevised femoral components were subsequently revised at a mean time of 14 and 11years from the index operation, and 22 and 24years from the primary operation, respectively. We concluded that revision of a stable component is not justifiable on the basis of its long duration in use or non-ideal position or possible loosening on radiographs.
本研究旨在评估单组件全髋关节翻修（索引手术）中未修正部分的长期结果。共纳入 44 名患者（46 髋），索引手术时的平均年龄为 58 岁。在最终随访时，19 个未修正髋臼组件中有 4 个（21%）和 27 个未修正股骨组件中有 6 个（22%）在索引手术后平均 14 年和 11 年时进行了翻修，分别在原发手术后 22 年和 24 年。我们的结论是，基于其长期使用、不理想位置或影像学上可能松动，对稳定的组件进行翻修是不合理的。
