Periacetabular osteotomy (PAO) is an effective joint-preserving procedure for developmental dysplasia of the hip. However, some patients report dissatisfaction after PAO. Because patient satisfaction is increasingly used as a health care quality metric, it is important to gain a better understanding of factors associated with patient satisfaction after PAO. The goal of this study was to investigate patient satisfaction among a cohort of Asian patients undergoing PAO. This study included 227 Asian patients who had undergone PAO at our institution between 1998 and 2016. The study participants completed a questionnaire assessing patient satisfaction, reasons for dissatisfaction, and postoperative Oxford Hip Score (OHS) and University of California, Los Angeles (UCLA), activity scale score. Based on their satisfaction levels, the participants were divided into 4 subgroups, and their demographic characteristics and postoperative patient-reported outcomes were compared. Of the 227 patients, 190 expressed satisfaction that correlated with OHS-pain, OHD-activities of daily living, and UCLA activity scale scores. Primary reasons for dissatisfaction after PAO were persistent pain (24 of 49, 49%), functional limitations (14 of 49, 29%), stiffness around the hip (4 of 49, 8%), unmet expectations (4 of 49, 8%), conversion to total hip arthroplasty (2 of 49, 4%), and complications (1 of 49, 2%). Multivariate analysis showed that preoperative Kellgren-Lawrence grades 1 and 3 were the significant predictive factors for satisfaction and dissatisfaction, respectively. The potential for lower patient satisfaction associated with Kellgren-Lawrence grade 3 because of persistent pain and functional limitations postoperatively suggests that consideration of preoperative severity of osteoarthritis could enhance patient satisfaction after PAO.

髋臼周围截骨术（PAO）是一种有效的髋关节发育不良的关节保留手术。然而，一些患者报告 PAO 后不满意。由于患者满意度越来越多地用作医疗保健质量指标，因此更好地了解与 PAO 后患者满意度相关的因素非常重要。本研究的目的是调查一组接受 PAO 的亚洲患者的患者满意度。这项研究包括 1998 年至 2016 年间在我们机构接受过 PAO 的 227 名亚洲患者。研究参与者完成了一份问卷调查，评估患者满意度、不满意原因和术后牛津髋关节评分 (OHS) 和加州大学洛杉矶分校 (UCLA) ，活动量表得分。根据他们的满意度，参与者分为4个亚组，比较他们的人口统计学特征和术后患者报告的结果。在 227 名患者中，190 名表达了与 OHS 疼痛、OHD 日常生活活动和 UCLA 活动量表评分相关的满意度。PAO 后不满意的主要原因是持续性疼痛（49 人中的 24 人，49%）、功能受限（49 人中的 14 人，29%）、髋关节僵硬（49 人中的 4 人，8%）、未达到预期（49 人中的 4 人，8 %）、转换为全髋关节置换术（49 例中的 2 例，4%）和并发症（49 例中的 1 例，2%）。多变量分析显示，术前 Kellgren-Lawrence 1 级和 3 级分别是满意度和不满意度的重要预测因素。由于术后持续疼痛和功能限制，与 Kellgren-Lawrence 3 级相关的患者满意度降低的可能性表明，考虑术前骨关节炎的严重程度可以提高 PAO 后的患者满意度。[骨科。20XX;4X(X):xx–xx.]
