BACKGROUND AND PURPOSE The influence of postoperative limping on patient satisfaction and amount of limping reduction following THA are not well documented. We (1) assessed if postoperative limping is associated with satisfaction 5 years after THA performed via the lateral or anterior approach; (2) evaluated the influence of surgical approach on amount of limping reduction following THA. PATIENTS AND METHODS We conducted a prospective cohort study of primary elective THAs performed in 2002-2013. Limping was assessed before and 5 years after surgery using the Harris Hip limping sub-score. Satisfaction was assessed at 5 years on a 5-point Likert scale. We compared proportions of satisfied patients among groups of limping. Evolution of limping before and after surgery was noted. Analyses were performed overall and stratified by pain and surgical approach. We used univariate and multivariate logbinomial regression models. RESULTS 1,257 patients were included (mean age 70 years). 81% had surgery via a lateral and 19% via an anterior approach. Before THA, 60% had moderate to severe limping and all reported pain. After THA, limping and pain improved; 9% of patients were dissatisfied. In multivariate analysis stratified on pain level, limping was associated with higher dissatisfaction. Similar results were obtained after lateral vs. anterior approach. INTERPRETATION Postoperative limping impacts patient satisfaction after THA. The association varied by degree of limping and absence or presence of pain. It was independent of surgical approach. 5 years after THA occurrence of limping was largely reduced after both a lateral and an anterior approach, with low evidence of a greater reduction under an anterior approach.

初次全髋关节置换术后的跛行和患者满意度：一项基于注册的队列研究。

背景和目的 术后跛行对患者满意度和 THA 术后跛行减少量的影响没有得到很好的记录。我们（1）评估了术后跛行是否与通过外侧入路或前入路进行 THA 5 年后的满意度相关；(2) 评估了手术入路对 THA 术后跛行减少量的影响。患者和方法 我们对 2002-2013 年进行的初次择期 THA 进行了一项前瞻性队列研究。使用哈里斯髋关节跛行子评分在手术前和手术后 5 年评估跛行。满意度在 5 年时采用 5 分李克特量表进行评估。我们比较了跛行组中满意患者的比例。注意到手术前后跛行的演变。分析是整体进行的，并根据疼痛和手术方法进行分层。我们使用单变量和多变量对数回归模型。结果 包括 1,257 名患者（平均年龄 70 岁）。81% 的患者通过外侧入路进行手术，19% 的患者通过前方入路进行手术。在 THA 之前，60% 的患者有中度至重度跛行，并且都报告有疼痛。THA 后，跛行和疼痛得到改善；9%的患者不满意。在按疼痛程度分层的多变量分析中，跛行与更高的不满相关。横向与前路入路后获得了类似的结果。解释 术后跛行会影响 THA 后患者的满意度。这种关联因跛行程度和是否存在疼痛而异。它与手术方法无关。
