After total hip arthroplasty (THA), patients today (who tend to be younger and more active than those who previously underwent this surgical procedure) have high expectations regarding functional outcome. Therefore, patients need to be well informed about recovery of physical functioning after THA.
The purpose of this study was to review publications on recovery of physical functioning after THA and examine the degree of recovery with regard to 3 aspects of functioning (ie, perceived physical functioning, functional capacity to perform activities, and actual daily activity in the home situation).
Data were obtained from the MEDLINE and EMBASE databases from inception to July 2009, and references in identified articles were tracked.
Prospective studies with a before-after design were included. Patients included in the analysis had to have primary THA for osteoarthritis.
Two reviewers independently checked the inclusion criteria, conducted the risk of bias assessment, and extracted the results. Data were pooled in a meta-analysis using a random-effects model.
A total of 31 studies were included. For perceived physical functioning, patients recovered from less than 50% preoperatively to about 80% of that of controls (individuals who were healthy) 6 to 8 months postsurgery. On functional capacity, patients recovered from 70% preoperatively to about 80% of that of controls 6 to 8 months postsurgery. For actual daily activity, patients recovered from 80% preoperatively to 84% of that of controls at 6 months postsurgery.
Only a few studies were retrieved that investigated the recovery of physical functioning longer than 8 months after surgery.
Compared with the preoperative situation, the 3 aspects of physical functioning showed varying degrees of recovery after surgery. At 6 to 8 months postoperatively, physical functioning had generally recovered to about 80% of that of controls.
在全髋关节置换术（THA）后，现今的患者（他们往往比以前接受过这种手术的患者更年轻、更活跃）对功能结果的期望很高。因此，患者需要对 THA 后身体功能的恢复有充分的了解。
本研究旨在回顾关于 THA 后身体功能恢复的文献，并检查在 3 个功能方面的恢复程度（即感知身体功能、执行活动的功能能力和实际日常活动在家中的情况）。
数据来自 MEDLINE 和 EMBASE 数据库，从建立到 2009 年 7 月，同时跟踪确定文章中的参考文献。
包括前瞻性研究，设计为前后对照。分析中纳入的患者必须进行原发性 THA 治疗骨关节炎。
两名审查员独立检查纳入标准、进行偏倚风险评估，并提取结果。使用随机效应模型进行荟萃分析对数据进行汇总。
共纳入 31 项研究。对于感知身体功能，患者从术前的不到 50%恢复到术后 6 至 8 个月时约为对照组（健康个体）的 80%。在功能能力方面，患者从术前的 70%恢复到术后 6 至 8 个月时约为对照组的 80%。对于实际日常活动，患者从术前的 80%恢复到术后 6 个月时约为对照组的 84%。
检索到的只有少数研究调查了手术后超过 8 个月的身体功能恢复情况。
与术前情况相比，术后身体功能的 3 个方面都有不同程度的恢复。术后 6 至 8 个月，身体功能已基本恢复到对照组的约 80%。
