PURPOSE
Unicompartmental Knee Arthroplasty (UKA) recorded an increased incidence of around 30% per year in the United States. Patient's experience and satisfaction after surgery were traditionally assessed by pre, and post-surgical scores and Patient-Reported Outcome Measures (PROMs) scales. Traditional scales as Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Oxford Knee Score (OKS) reported high ceiling effect. Patients treated by UKA usually perform well; therefore, it is necessary to have a PROMs' scale with a low ceiling effect as the Forgotten Joint Score-12 (FJS-12). PROMs have to be validated in the local language to be used. This study aims to perform a psychometric validation of the Italian version of FJS-12 for UKA for the first time.
METHODS
Between January 2019 and October 2019, 44 patients were included. Each patient completed both the FJS-12 Italian version and the WOMAC Italian version in preoperative follow-up, after 2-week and 1-month, 3-month, and 6-month postoperative follow-up. Cronbach's α, intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable change (MDC) were calculated to evaluate the reliability. The Pearson coefficient was used to assess validity. The Effect Size (ES) was used to test the responsiveness.
RESULTS
A range of Cronbach's α between 0.90 and 0.95 indicated good internal consistency for the FJS-12. The test-retest reliability was acceptable (i.e., the ICC was higher than 0.7) at each follow-up. The Pearson correlation coefficient between the FJS-12 and WOMAC was - 0.11 (n.s.) at preoperative follow-up, r = 0.47 (P = 0.001) at 1 month, r = 0.57 (P < 0.001) at 3 months, and r = 0.57 (P < 0.001) at 6 months. Therefore, except for the preoperative period, the validity of the FJS-12 score was assessed.
CONCLUSION
The FJS-12 represents a valid and reliable tool with a low ceiling effect to assess the outcomes improvement in UKA patients. Therefore, validating and translating this score in different languages could help perform more accurate studies on outcomes after UKA.

Level III, diagnostic study.
目的
在美国，单髁膝关节置换术（UKA）的发病率每年增长约30%。传统上，手术前后的评分以及患者报告结局测量（PROMs）量表用于评估患者术后的体验和满意度。像西安大略和麦克马斯特大学骨关节炎指数（WOMAC）以及牛津膝关节评分（OKS）等传统量表显示出较高的天花板效应。接受UKA治疗的患者通常表现良好；因此，有必要使用一种天花板效应较低的PROMs量表，如遗忘关节评分-12（FJS-12）。PROMs必须经过本地语言验证才能使用。本研究旨在首次对意大利语版的UKA-FJS-12进行心理测量学验证。
方法
2019年1月至2019年10月期间，纳入44例患者。每位患者在术前随访、术后2周、1个月、3个月和6个月随访时均完成了意大利语版的FJS-12和WOMAC。计算Cronbach's α、组内相关系数（ICC）、测量标准误差（SEM）和最小可检测变化（MDC）以评估可靠性。使用Pearson系数评估效度。使用效应量（ES）测试反应性。
结果
FJS-12的Cronbach's α范围在0.90至0.95之间，表明其内部一致性良好。每次随访时的重测信度均可接受（即ICC高于0.7）。术前随访时，FJS-12与WOMAC之间的Pearson相关系数为-0.11（无统计学意义），1个月时r = 0.47（P = 0.001），3个月时r = 0.57（P < 0.001），6个月时r = 0.57（P < 0.001）。因此，除术前阶段外，对FJS-12评分的效度进行了评估。
结论
FJS-12是一种有效且可靠的工具，具有较低的天花板效应，可用于评估UKA患者的结局改善情况。因此，对该评分进行不同语言的验证和翻译有助于对UKA术后结局进行更准确的研究。
