The purpose of this study was to evaluate the outcome improvements after total hip arthroplasty (THA) using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) in patients who underwent THA with a navigation system in our institutions. The subjects were 219 patients. All patients had adequate data to allow complete scoring of the WOMAC for a 1-year postoperative follow-up. CT-based navigation was used in all THAs. Postoperatively, no restrictions were imposed on patients' ADL. One year after surgery, the average WOMAC pain subscale score was 1.8 ± 2.9, the stiffness subscale score was 1.1 ± 1.6, and the physical function subscale score was 7.5 ± 11.6 points. The number of patients whose score for the WOMAC physical function score was 0 points was 61 (27.9%). A lower WOMAC score usually represents a better status. In some of the most difficult functions, such as ascending stairs, bending to the floor, putting on socks/stockings, and heavy domestic duties, the scores tended to be higher than the other scores postoperatively. These results show that THA using navigation can improve patients' postoperative QOL.
本研究的目的是使用西安大略和麦克马斯特大学骨关节炎指数（WOMAC）评估在我们机构接受导航系统全髋关节置换术（THA）的患者术后的疗效改善情况。研究对象为219例患者。所有患者均有足够的数据，以便在术后1年随访时对WOMAC进行完整评分。所有THA均采用基于CT的导航。术后，患者的日常生活活动（ADL）没有限制。术后1年，WOMAC疼痛分量表平均评分为1.8±2.9分，僵硬分量表评分为1.1±1.6分，身体功能分量表评分为7.5±11.6分。WOMAC身体功能评分为0分的患者有61例（27.9%）。较低的WOMAC评分通常代表较好的状态。在一些最困难的功能中，如上下楼梯、弯腰到地面、穿袜子/长袜以及繁重的家务劳动，术后这些功能的评分往往高于其他评分。这些结果表明，使用导航的THA可以改善患者术后的生活质量。
