Periacetabular osteotomy (PAO) is a surgery for persons with symptomatic acetabular dysplasia (AD) that increases acetabular coverage of the femoral head for reducing hip pain and improving function. Patient-reported outcomes (PROs) are significantly improved following PAO, yet little is known regarding mobility-related outcomes. This narrative review provides a synthesis of evidence regarding PROs and mobility-related outcomes in persons with AD following PAO. We further identified important future research directions, chiefly the need for measurement of real-world outcomes. We searched PubMed using comprehensive predefined search terms. We included studies that (i) enrolled persons with AD undergoing PAO, (ii) included PROs and/or mobility-related outcomes and (iii) were written in English. We synthesized and summarized study characteristics and findings. Twenty-three studies were included in this review. Commonly evaluated PROs included pain (n = 14), hip function (n = 19) and quality of life (n = 9). Mobility-related outcomes included self-reported physical activity (PA; n = 11), walking speed and cadence (n = 4), device-measured PA (n = 2), and sit-to-stand, four-square-step and timed stair ascent tests (n = 1). Persons with AD had significant improvements in PROs following PAO, yet mobility-related outcomes (e.g. walking speed and device-measured PA levels) did not change over 1 year following PAO. Few studies have evaluated mobility-related outcomes following PAO, and these studies were of a low methodological quality. Future research might include experience sampling data collection approaches and body-worn devices as free-living, technology-driven methodologies to evaluate mobility and other outcomes in persons with AD undergoing PAO.

髋臼发育不良患者髋臼周围截骨术的活动性相关结果：为实际结果的测量奠定基础

髋臼周围截骨术 (PAO) 是一种针对有症状的髋臼发育不良 (AD) 患者的手术，可增加股骨头的髋臼覆盖范围，以减轻髋部疼痛并改善功能。PAO 后患者报告的结果 (PROs) 显着改善，但关于移动相关的结果知之甚少。该叙述性综述提供了关于 PAO 后 AD 患者的 PROs 和移动相关结果的证据综合。我们进一步确定了重要的未来研究方向，主要是衡量现实世界结果的需要。我们使用全面的预定义搜索词搜索 PubMed。我们纳入了以下研究：(i) 纳入接受 PAO 的 AD 患者，(ii) 包括 PRO 和/或与移动相关的结果，以及 (iii) 用英语编写。我们综合和总结了研究特征和发现。本综述纳入了 23 项研究。通常评估的 PRO 包括疼痛 (n = 14)、髋关节功能 (n = 19) 和生活质量 (n = 9)。与移动性相关的结果包括自我报告的身体活动（PA；n = 11）、步行速度和节奏（n = 4）、设备测量的 PA（n = 2）和坐立式四方步和定时楼梯上升测试（n = 1）。AD 患者在 PAO 后的 PROs 有显着改善，但与移动性相关的结果（例如步行速度和设备测量的 PA 水平）在 PAO 后 1 年内没有变化。很少有研究评估 PAO 后与移动相关的结果，而且这些研究的方法学质量较低。
