The purpose of the current study was to update the results of a prospective, single-surgeon series of primary Charnley total hip arthroplasties performed with cement. This investigation is one of the first studies in which hips treated with total hip arthroplasty with cement were followed for a minimum of thirty years. Twenty-seven patients (thirty-four [10.3%] of the hips in the initial study group) were alive at a minimum of thirty years postoperatively. These patients served as the focus of the present study. Revision because of aseptic loosening of the acetabular component was performed in 7.3% (twenty-three) of the hips from the original study group (excluding those revised because of infection or dislocation) and 26% (eight) of the hips in the living cohort. Revision because of aseptic loosening of the femoral component was performed in 3.2% (ten) of the hips from the original study group (excluding those revised because of infection or dislocation) and 10% (three) of the hips in the living patients. Since the twenty-five-year review, three hips were revised (one because of acetabular loosening, one because of femoral loosening, and one because of instability). This end-result study demonstrated the remarkable durability of cemented Charnley total hip replacements over a span of three decades, with 88% of the original prostheses intact at the time of the final follow-up or at the patient's death.
本研究的目的是更新一组由同一位外科医生采用骨水泥进行的Charnley初次全髋关节置换术的前瞻性研究结果。本调查是首批对采用骨水泥全髋关节置换术治疗的髋关节进行至少30年随访的研究之一。27例患者（占初始研究组中髋关节的34个[10.3%]）术后至少存活30年。这些患者是本研究的重点。在原研究组中，7.3%（23个）的髋关节（不包括因感染或脱位而翻修的髋关节）以及在存活队列中的26%（8个）的髋关节因髋臼组件无菌性松动而进行了翻修。在原研究组中，3.2%（10个）的髋关节（不包括因感染或脱位而翻修的髋关节）以及在存活患者中的10%（3个）的髋关节因股骨组件无菌性松动而进行了翻修。自25年的回顾以来，有3个髋关节进行了翻修（1个因髋臼松动，1个因股骨松动，1个因不稳定）。这项最终结果研究表明，骨水泥型Charnley全髋关节置换术在三十年的时间跨度内具有显著的耐用性，在最后一次随访时或患者死亡时，88%的原始假体仍完好无损。
