We present the extended follow-up (≥ 20 years) of a series of fully hydroxyapatite-coated femoral components used in 72 primary total hip replacements (THRs). Earlier results of this cohort have been previously published. All procedures were performed between 1986 and 1991. The series involved 45 women and 15 men with 12 bilateral procedures. Their mean age at the time of surgery was 60 years (46 to 80) and the mean duration of follow-up was 22.5 years (20 to 25). At final follow-up, the mean Merle d'Aubigné and Postel hip scores were 5.5 (4.5 to 6), 3.8 (3.5 to 5) and 3.3 (3.0 to 5.0) for pain, mobility and function, respectively. Of the patients 92% were very satisfied at the time of final follow-up. There were seven revisions: six of the acetabular component for aseptic loosening and one of both the stem and the acetabular component for loosening due to deep infection. The survival of this prosthesis at 22.5 years with revision for any reason as the endpoint was 91.7% (95% confidence interval (CI) 84 to 99). Survival with aseptic loosening of the stem as the endpoint was 100% (95% CI 90 to 100). This prosthesis provides pain relief in the long term. Survival of this component is comparable to the best results for primary THR with any means of fixation.
我们呈现了一组完全羟磷灰石涂层股骨假体在 72 例初次全髋关节置换术中的长期随访（≥20 年）。该队列的早期结果已先前发表。所有手术均在 1986 年至 1991 年期间进行。该系列包括 45 名女性和 15 名男性，其中 12 例为双侧手术。他们手术时的平均年龄为 60 岁（46 至 80 岁），平均随访时间为 22.5 年（20 至 25 年）。在最终随访时，Merle d'Aubigné 和 Postel 髋关节评分的平均值分别为 5.5（4.5 至 6）、3.8（3.5 至 5）和 3.3（3.0 至 5.0），分别用于疼痛、活动度和功能。在最终随访时，92%的患者非常满意。有 7 例翻修：6 例髋臼组件因无菌性松动，1 例股骨柄和髋臼组件因深部感染而松动。以任何原因翻修为终点，该假体在 22.5 年时的生存率为 91.7%（95%置信区间 84 至 99）。以股骨柄无菌性松动为终点的生存率为 100%（95%置信区间 90 至 100）。该假体可长期缓解疼痛。该假体的生存率与任何固定方式的初次全髋关节置换术的最佳结果相当。
