UNLABELLED
This study reports the responsiveness to change and minimal clinically important difference (MCID) of three patient reported outcome measures following total hip arthroplasty (THA) and total knee arthroplasty (TKA). Patient-reported outcome measures were collected preoperatively and 3 months postoperatively for 391 patients enrolled in the California Joint Replacement Registry. Effect size, standardized response means, and MCID were calculated for each measure. The WOMAC and the SF12v2 physical component summary (PCS) score were the most responsive to perioperative changes. The MCID was 4.97 for the SF12v2 PCS and 10.21 for the WOMAC. THA patients were more likely to exhibit improvements above the MCID than TKA patients. The WOMAC and SF12v2 PCS are useful to measure health status changes in TJA patients.
LEVEL OF EVIDENCE
Prognostic Level II.

本研究报告了全髋关节置换术（THA）和全膝关节置换术（TKA）后三种患者报告结局指标对变化的反应性及最小临床重要差异（MCID）。对加利福尼亚关节置换登记处登记的391例患者在术前和术后3个月收集患者报告结局指标。计算每种指标的效应量、标准化反应均值和MCID。WOMAC和SF12v2身体成分总结（PCS）评分对围手术期变化反应最为敏感。SF12v2 PCS的MCID为4.97，WOMAC的MCID为10.21。THA患者比TKA患者更有可能表现出高于MCID的改善。WOMAC和SF12v2 PCS有助于测量TJA患者的健康状况变化。
