Background:

For active patients undergoing periacetabular osteotomy (PAO), returning to and maintaining a high level of activity postoperatively is a priority.

Purpose:

To evaluate the maintenance of activity levels at midterm follow-up in active patients treated with PAO for symptomatic acetabular dysplasia.

Study Design:

Case series; Level of evidence, 4.

Methods:

Patients who underwent PAO for symptomatic acetabular dysplasia between June 2006 and August 2013 were identified by a retrospective review of our prospective longitudinal institutional Hip Preservation Database. All patients with a preoperative University of California, Los Angeles (UCLA) score of ≥7 and a potential minimum 5 years of follow-up were included in the study. Functional outcome measures were the UCLA score, modified Harris Hip Score (mHHS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The maintenance of high activity levels was defined as a UCLA score of ≥7 at final follow-up. Radiographic parameters were measured. Statistical significance was defined as a P value <.05.

Results:

A total of 66 hips (58 patients) were included. The mean age was 25.3 years (range, 14-47 years), the mean body mass index was 23.9 kg/m² (range, 19-32 kg/m²), and 72% were female. The mean follow-up was 6.8 years (range, 5-11 years). There were 67% of patients who maintained a UCLA score of ≥7. Patient-reported outcomes improved postoperatively from preoperatively for the mHHS (88 ± 14 vs 67 ± 17, respectively; P < .001) and WOMAC (89 ± 15 vs 73 ± 20, respectively; P < .001). The lateral center-edge angle, anterior center-edge angle, and acetabular inclination were significantly improved at final follow-up (P < .001). Only 4 patients (7%) cited postoperative activity limitations as being caused by hip pain. There were no conversions to total hip arthroplasty.

Conclusion:

The majority (67%) of active patients returned to preoperative or higher activity levels after PAO at midterm follow-up.

接受髋臼周围截骨术的活跃患者中期随访时的活动水平维持。

背景：

对于接受髋臼周围截骨术（PAO）的活跃患者，术后恢复并保持高水平的活动是重中之重。

目的：

为了评估在有症状的髋臼发育不良的PAO治疗的活跃患者的中期随访中维持活动水平。

学习规划：

案例系列；证据水平4。

方法：

通过回顾性研究我们的前瞻性纵向机构髋关节保存数据库，可以确定在2006年6月至2013年8月期间接受过PAO症状性髋臼异型增生的患者。该研究纳入了术前加利福尼亚大学洛杉矶分校（UCLA）得分≥7且可能至少随访5年的所有患者。功能性结局指标包括UCLA评分，改良的Harris髋关节评分（mHHS）以及西安大略省和麦克马斯特大学骨关节炎指数（WOMAC）。维持高活动水平的定义为最终随访时UCLA评分≥7。测量射线照相参数。统计显着性定义为P值<.05。

结果：

总共包括66个髋关节（58例患者）。平均年龄为25.3岁（范围为14-47岁），平均体重指数为23.9 kg / m ²（范围为19-32 kg / m ²），女性为72％。平均随访时间为6.8年（范围5-11年）。有67％的患者的UCLA得分保持≥7。患者报告的mHHS手术后结局较术前有所改善（分别为88±14 vs 67±17；P <.001）和WOMAC（分别为89±15 vs 73±20；P <.001）。在最终随访中，侧向中心边缘角，前中心边缘角和髋臼倾斜度得到了显着改善（P<.001）。只有4例患者（7％）认为术后活动受限是由髋部疼痛引起的。没有转换为全髋关节置换术。

结论：

活动期患者中的大多数（67％）在中期随访中接受PAO后恢复到术前或更高的活动水平。
