Patient satisfaction is becoming increasingly important as a crucial outcome measure for total knee arthroplasty. We aimed to determine how well commonly used clinical outcome scales correlate with patient satisfaction after total knee arthroplasty. In particular, we sought to determine whether patient satisfaction correlates better with absolute postoperative scores or preoperative to 12-month postoperative changes. Patient satisfaction was evaluated using 4 grades (enthusiastic, satisfied, noncommittal, and disappointed) for 438 replaced knees that were followed for longer than 1 year. Outcomes scales used the American Knee Society, Western Ontario McMaster University Osteoarthritis Index scales, and Short Form-36 scores. Correlation analyses were performed to investigate the relation between patient satisfaction and the 2 different aspects of the outcome scales: postoperative scores evaluated at latest follow-ups and preoperative to postoperative changes. The Western Ontario McMaster University Osteoarthritis Index scales function score was most strongly correlated with satisfaction (correlation coefficient=0.45). Absolute postoperative scores were better correlated with satisfaction than the preoperative to postoperative changes for all scales.

患者满意度作为全膝关节置换术的一个重要结果衡量标准变得越来越重要。我们旨在确定常用的临床结果评估量表与全膝关节置换术后患者满意度的相关性。具体而言，我们试图确定患者满意度与术后绝对评分或术前至 12 个月术后变化的相关性更好。438 个接受了 1 年以上随访的置换膝关节采用 4 个等级（热情、满意、不置可否和失望）来评估患者满意度。使用美国膝关节协会、安大略西部麦克马斯特大学骨关节炎指数量表和健康调查简表 36 评分来评估结果量表。进行相关性分析以研究患者满意度与 2 种不同的结果量表方面之间的关系：在最新随访时评估的术后评分以及术前到术后的变化。安大略西部麦克马斯特大学骨关节炎指数量表的功能评分与满意度的相关性最强（相关系数=0.45）。对于所有量表，术后绝对评分与满意度的相关性均优于术前至术后的变化。
