我们使用了术后三年 862 例全膝关节置换术和 716 例全髋关节置换术的前瞻性数据，以得出并验证简化的西安大略省和麦克马斯特大学骨关节炎指数 (WOMAC) 功能量表。缩小的比例是根据临床专家的建议以及数据分析得出的。该量表进行了有效性、可靠性和反应性测试。保留的项目包括：爬楼梯、从坐起身、在平地上行走、进出汽车、穿袜子、从床上起身和坐。缩小量表和满量表与其他功能测量具有可比的、中等的相关性，证实了收敛效度。 Cronbach 的 alpha 较高（alpha > 0.85），缩小的量表证实了可靠性。缩小量表的反应性更大（完整 = 1.4，缩小 = 1.6）。这种缩小版本的 WOMAC 功能量表为全关节置换后使用的全功能量表提供了实用、有效、可靠和反应灵敏的替代方案。需要进一步的工作来证明其更广泛的适用性。
We used prospective data from 862 total knee and 716 total hip replacements three years after surgery in order to derive and validate a reduced Western Ontario and McMasters University Osteoarthritis Index (WOMAC) function scale. The reduced scale was derived using the advice of clinical experts as well as analysis of data. The scale was tested for validity, reliability and responsiveness.Items which were retained included: ascending stairs, rising from sitting, walking on the flat, getting in or out of a car, putting on socks, rising from bed, and sitting.The reduced and full scales had comparable, moderate correlations with other measures of function, confirming convergent validity. Cronbach's alpha was high (alpha > 0.85) with the reduced scale confirming reliability. Responsiveness was greater for the reduced scale (full = 1.4, reduced = 1.6).This reduced version of the WOMAC function scale provides a practical, valid, reliable and responsive alternative to the full function scale for use after total joint replacement. Further work is needed to demonstrate its wider applicability.
