Commonly used patient-reported outcome measurement (PROM) tools for knee joint have a ceiling effect and may not be able to differentiate between patients achieving outcomes better than the upper limit of the score. Forgotten joint score-12 (FJS-12) is said to be free of this limitation. FJS-12 has been translated and validated in different languages. This study aims to translate and validate FJS-12 in Hindi (Hindi FJS-12).
Hindi FJS-12 was tested for comprehensibility in a pilot study in 20 patients. This was followed by a prospective cohort study including 140 patients of bilateral total knee arthroplasty, with a minimum follow-up of 12 months. The mean age of the patients was 62.0 ± 14.5 years. There were 77 (55.2%) males and remaining were females. All patients were asked to fill up questionnaires of Hindi FJS-12, WOMAC, KSS and OKS. Hindi FJS-12 was tested for validity, reliability, responsiveness, floor effect and ceiling effect. Construct validity was expressed as the Pearson correlation coefficient. Internal consistency was expressed as Cronbach's alpha and test-retest reliability as the intra-class correlation coefficient (ICC).
In the pilot study, it was seen that all the questions were well answered by most of the participants. The main study showed good construct validity with Hindi FJS-12 showing moderate correlation with WOMAC, KSS and OKS (Pearson coefficients 0.45, 0.32, 0.37, respectively). Hindi FJS-12 had excellent internal consistency with Cronbach's alpha of 0.93 (95% CI 0.90, 0.97). ICC was 0.95 (95% CI 0.90, 0.99). No floor or ceiling effect was observed.
Hindi FJS-12 has high validity, reliability and reproducibility for knee function after TKA. It is devoid of floor or ceiling effect. Thus, it can be successfully used for studying knee function in the Indian population.
Prospective cohort study, Level II.
常用于膝关节的患者报告结局测量（PROM）工具存在天花板效应，可能无法区分患者的结局是否优于评分上限。据说遗忘关节评分-12（FJS-12）不存在此限制。FJS-12 已被翻译成多种语言并经过验证。本研究旨在将 FJS-12 翻译成印地语（印地语 FJS-12）并对其进行验证。
在一项 20 例患者的试点研究中，对印地语 FJS-12 的理解能力进行了测试。随后，对 140 例双侧全膝关节置换术患者进行前瞻性队列研究，随访时间至少为 12 个月。患者的平均年龄为 62.0±14.5 岁。其中 77 例（55.2%）为男性，其余为女性。所有患者均填写印地语 FJS-12、WOMAC、KSS 和 OKS 问卷。测试了印地语 FJS-12 的有效性、可靠性、反应性、地板效应和天花板效应。结构效度用 Pearson 相关系数表示。内部一致性用 Cronbach 的 alpha 表示，测试-重测信度用组内相关系数（ICC）表示。
在试点研究中，发现大多数参与者都能很好地回答所有问题。主要研究显示，印地语 FJS-12 具有良好的结构效度，与 WOMAC、KSS 和 OKS 呈中度相关（Pearson 系数分别为 0.45、0.32、0.37）。印地语 FJS-12 具有极好的内部一致性，Cronbach 的 alpha 为 0.93（95%CI 0.90，0.97）。ICC 为 0.95（95%CI 0.90，0.99）。未观察到地板或天花板效应。
印地语 FJS-12 具有较高的有效性、可靠性和可重复性，可用于研究 TKA 后膝关节功能。它没有地板或天花板效应。因此，它可以成功地用于研究印度人群的膝关节功能。
前瞻性队列研究，II 级。
