No studies have compared sports participation between total hip arthroplasty (THA) and periacetabular osteotomy (PAO) in matched Asian cohorts. We investigated sports participation and activity levels in Asian THA cohort, and compared them between THA and PAO cohorts.
Multivariate analyses were applied to determine which factors were associated with postoperative sports participation and University of California-Los Angeles (UCLA) activity score in (1) 524 THA patients and (2) 487 acetabular dysplasia patients (295 THA patients and 192 PAO patients). In addition, postoperative sports participation and UCLA score were compared between 62 THA and 62 PAO patients after adjusting for baseline characteristics with propensity score matching.
Sports participation and UCLA score significantly increased after THA (P < .001 in both analyses). Preoperative sports participation was the factor most associated with both postoperative sports participation and UCLA score in both 524 THA patients and 487 acetabular dysplasia patients (P < .001 in all analyses). Multivariate analysis in 487 acetabular dysplasia patients demonstrated that THA, compared with PAO, was negatively associated with postoperative sports participation (P < .001), but not postoperative UCLA score (P = .22). THA patients showed significantly lower rate of postoperative sports participation (32.3% and 51.6%, respectively, P = .046), but not postoperative UCLA score (5.0 ± 1.6 and 5.2 ± 1.9, respectively, P = .47) compared with matched PAO patients.
THA significantly increased both sports participation and activity levels. Both multivariate and propensity score-matched analyses showed that postoperative activity levels were comparable between THA and PAO cohorts.
在匹配的亚洲队列中，尚无研究比较全髋关节置换术（THA）和髋臼周围截骨术（PAO）之间的运动参与情况。我们调查了亚洲 THA 队列的运动参与情况和活动水平，并比较了 THA 和 PAO 队列之间的情况。
应用多变量分析确定哪些因素与（1）524 例 THA 患者和（2）487 例髋臼发育不良患者（295 例 THA 患者和 192 例 PAO 患者）术后运动参与和加州大学洛杉矶分校（UCLA）活动评分相关。此外，在通过倾向评分匹配调整基线特征后，比较了 62 例 THA 和 62 例 PAO 患者的术后运动参与和 UCLA 评分。
THA 后运动参与度和 UCLA 评分显著增加（两种分析均 P <.001）。在 524 例 THA 患者和 487 例髋臼发育不良患者中，术前运动参与度是与术后运动参与度和 UCLA 评分均最相关的因素（两种分析均 P <.001）。487 例髋臼发育不良患者的多变量分析表明，与 PAO 相比，THA 与术后运动参与呈负相关（P <.001），但与术后 UCLA 评分无关（P =.22）。THA 患者术后运动参与率明显较低（分别为 32.3%和 51.6%，P =.046），但术后 UCLA 评分无差异（分别为 5.0 ± 1.6 和 5.2 ± 1.9，P =.47），与匹配的 PAO 患者相比。
THA 显著增加了运动参与度和活动水平。多变量和倾向评分匹配分析均表明，THA 和 PAO 队列之间的术后活动水平相当。
