AIMS Although periacetabular osteotomies are widely used for the treatment of symptomatic dysplastic hips, long-term surgical outcomes and patient-reported outcome measures (PROMs) are still unclear. Accordingly, we assessed hip survival and PROMs at 20 years after transpositional osteotomy of the acetabulum (TOA). METHODS A total of 172 hips in 159 patients who underwent TOA were followed up at a mean of 21.02 years (16.6 to 24.6) postoperatively. Kaplan-Meier analysis was used to assess survivorship with an endpoint of total hip arthroplasty (THA). PROMs included the visual analogue scale (VAS) Satisfaction, VAS Pain, Oxford Hip Score (OHS), and Forgotten Joint Score-12 (FJS-12). Thresholds for favourable outcomes for OHS (≥ 42) and FJS-12 (≥ 51) were obtained using the receiver operating characteristic curve with VAS Satisfaction ≥ 50 and VAS Pain < 20 as anchors. RESULTS THA was performed on 37 hips (21.5%) by the latest follow-up. Kaplan-Meier analysis indicated that the hip survival rate at 20 years was 79.7% (95% confidence interval (CI) 73.7 to 86.3). Multivariate analysis showed that preoperative Tönnis grade significantly influenced hip survival. Tönnis grades 0, 1, and 2 were associated with 20-year survival rates of 93.3% (95% CI 84.8 to 100), 86.7% (95% CI 79.8 to 94.3), and 54.8% (95% CI 41.5 to 72.3), respectively. More than 60% of the patients exhibited favourable PROMs. An advanced Tönnis grade at the latest follow-up and a higher BMI were both significantly associated with unfavourable OHS, but not with other PROMs. CONCLUSION This study demonstrated the durability of TOA for hips with Tönnis grades 0 to 1 at 20 years. While the presence of advanced osteoarthritis and higher BMI was associated with lower hip functions (OHS), it was not necessarily associated with worse patient satisfaction and joint awareness.

髋臼转位截骨术治疗发育不良髋关节后的 20 年髋关节存活率和患者报告的结果测量。

目的 尽管髋臼周围截骨术被广泛用于治疗有症状的髋关节发育不良，但长期手术结果和患者报告结果测量 (PROM) 仍不清楚。因此，我们评估了髋臼转位截骨术 (TOA) 后 20 年的髋关节存活率和 PROM。方法 159 例接受 TOA 的患者共 172 髋，术后平均随访 21.02 年（16.6 ～ 24.6）。Kaplan-Meier 分析用于评估以全髋关节置换术 (THA) 为终点的生存率。PROM 包括视觉模拟评分 (VAS) 满意度、VAS 疼痛、牛津髋关节评分 (OHS) 和被遗忘的关节评分 12 (FJS-12)。使用以 VAS 满意度 ≥ 50 和 VAS 疼痛 < 20 为锚点的受试者工作特征曲线获得 OHS（≥ 42）和 FJS-12（≥ 51）的良好结果的阈值。结果 通过最近的随访，对 37 髋 (21.5%) 进行了 THA。Kaplan-Meier 分析表明 20 年髋关节存活率为 79.7%（95% 置信区间 (CI) 73.7 至 86.3）。多变量分析显示术前 Tönnis 分级显着影响髋关节生存率。Tönnis 0、1 和 2 级与 93.3%（95% CI 84.8 至 100）、86.7%（95% CI 79.8 至 94.3）和 54.8%（95% CI 41.5 至 72.3）的 20 年生存率相关， 分别。超过 60% 的患者表现出良好的 PROM。最新随访中的高级 Tönnis 分级和较高的 BMI 均与不利的 OHS 显着相关，但不适用于其他 PROM。结论 本研究证明了 TOA 对 Tönnis 等级为 0 至 1 的髋关节在 20 年时的耐久性。虽然晚期骨关节炎和较高的 BMI 与较低的髋关节功能 (OHS) 相关，但并不一定与较差的患者满意度和关节意识相关。引用这篇文章：骨关节 J 2022;104-B(7):767-774。
