We evaluated the outcome of 41 consecutive Charnley low-friction arthroplasties (LFAs) performed by a single surgeon in 28 patients aged ≤ 35 years at operation between 23 and 36 years previously. There were 20 women and eight men with a mean age of 32 years (23 to 35) at surgery. Two patients (three hips) were lost to follow-up at 12 and 17 years post-operatively, respectively, and one patient (one hip) died at 13 years post-operatively. These patients were excluded from the final evaluation. The survival rate of the acetabular components was 92.7% (95% confidence interval (CI) 88.7 to 96.7) at ten years, 67.1% (95% CI 59.75 to 74.45) at 20 years and 53.2% (95% CI 45.3 to 61.1) at 25 years. For the femoral component the survival was 95.1% (95% CI 91.8 to 98.5) at ten years, 77.1% (95% CI 73.9 to 80.3) at 20 years and 68.2% (95% CI 60.7 to 75.8) at 25 years. The results indicate that the Charnley LFA remains a reasonable choice in the treatment of young patients and can serve for comparison with newer techniques and implants.
我们评估了一位外科医生在 23 至 36 年前对 28 名年龄均≤35 岁的患者进行的 41 例连续 Charnley 低摩擦关节置换术 (LFA) 的结果。其中有 20 名女性和 8 名男性，手术时的平均年龄为 32 岁（23 至 35 岁）。两名患者（三个髋关节）分别在术后 12 年和 17 年失访，一名患者（一个髋关节）在术后 13 年死亡。这些患者被排除在最终评估之外。髋臼部件的 10 年生存率为 92.7%（95%置信区间（CI）88.7 至 96.7），20 年生存率为 67.1%（95% CI 59.75 至 74.45），25 年生存率为 53.2%（95% CI 45.3 至 61.1）。股骨部件的生存率为 10 年时为 95.1%（95% CI 91.8 至 98.5），20 年时为 77.1%（95% CI 73.9 至 80.3），25 年时为 68.2%（95% CI 60.7 至 75.8）。结果表明，Charnley LFA 仍然是治疗年轻患者的合理选择，并可与新技术和植入物进行比较。
