Although the Western Ontario and McMaster Universities (WOMAC) osteoarthritis index was originally developed for the assessment of non-operative treatment, it is commonly used to evaluate patients undergoing either total hip (THR) or total knee replacement (TKR). We assessed the importance of the 17 WOMAC function items from the perspective of 1198 patients who underwent either THR (n = 704) or TKR (n = 494) in order to develop joint-specific short forms. After these patients were administered the WOMAC pre-operatively and at three, six, 12 and 24 months' follow-up, they were asked to nominate an item of the function scale that was most important to them. The items chosen were significantly different between patients undergoing THR and those undergoing TKR (p < 0.001), and there was a shift in the priorities after surgery in both groups. Setting a threshold for prioritised items of ≥ 5% across all follow-up, eight items were selected for THR and seven for TKR, of which six items were common to both. The items comprising specific WOMAC-THR and TKR function short forms were found to be equally responsive compared with the original WOMAC function form.
尽管西安大略大学和麦克马斯特大学（WOMAC）骨关节炎指数最初是为非手术治疗的评估而开发的，但它通常用于评估接受全髋关节置换术（THR）或全膝关节置换术（TKR）的患者。我们从 1198 名接受 THR（n=704）或 TKR（n=494）的患者的角度评估了 WOMAC 功能 17 项的重要性，以便开发特定于关节的简短形式。在这些患者接受术前以及术后 3、6、12 和 24 个月的随访后，我们要求他们提名对他们最重要的功能量表中的一项。接受 THR 和 TKR 治疗的患者选择的项目明显不同（p<0.001），并且两组患者在手术后的优先级都发生了变化。在所有随访中，将优先项目的阈值设定为≥5%，选择了 8 项用于 THR，7 项用于 TKR，其中 6 项适用于两者。与原始 WOMAC 功能表相比，发现包含特定 WOMAC-THR 和 TKR 功能简短形式的项目同样具有响应性。
