To assess the reliability, validity and responsiveness of the Hindi version of the Knee Injury and Osteoarthritis Outcome Score (H-KOOS) in osteoarthritic knee.
Two hundred and fourteen patients of osteoarthritis knee (OA) between 40 and 80 years of age were evaluated with H-KOOS, Short form health survey (SF12v2) and the WHOQOL-BREF questionnaire. The H-KOOS was re-evaluated after 48 h in 125 patients to assess the test-retest reliability. For responsiveness, 40 patients were treated with the intra-articular hyaluronic acid injection, and the effect was assessed after 6 weeks.
Most of the domains in H-KOOS did not show a ceiling effect. The floor values were observed in 3.75% of patients in sports/recreation function and 2.75% of patients in Quality of life (QoL). The test-retest reliability was excellent with the Intraclass-Correlation-Coefficient (ICC) ranging from 0.89 to 0.94. Internal consistency as assessed using Cronbach's alpha coefficient was acceptable for pain, activities of daily living (ADL) and sport/recreation function (range 0.86-0.93); however, symptoms and QoL had weak internal consistency. There were moderate to strong correlations (r = 0.35 to 0.6) between domains measuring similar constructs in H-KOOS, SF12v2 and WHOQOL-BREF indicating good convergent construct validity. The responsiveness as measured by the effect size (ES) and standardized response mean (SRM) was large for pain (ES 0.9, SRM 0.8), moderate for Sport/Rec (ES 0.66, SRM 0.2) and small for ADL, QoL and Symptoms subscales.
The Hindi version KOOS is a valid, reliable and responsive measure to evaluate osteoarthritis knee with minimal ceiling and floor effects.
Prospective cohort study, level II.
评估印地语版膝关节损伤和骨关节炎结局评分（H-KOOS）在膝关节骨关节炎中的可靠性、有效性和反应度。
对 214 名 40-80 岁膝关节骨关节炎患者进行 H-KOOS、简明健康调查量表（SF12v2）和世界卫生组织生活质量量表简表（WHOQOL-BREF）评估。125 名患者在 48 小时后再次评估 H-KOOS，以评估测试-重测信度。为了评估反应度，40 名患者接受关节内透明质酸注射治疗，6 周后评估疗效。
H-KOOS 的大多数领域没有表现出天花板效应。在运动/娱乐功能和生活质量（QoL）方面，分别有 3.75%和 2.75%的患者出现地板值。采用组内相关系数（ICC）评估，测试-重测信度极好，范围为 0.89-0.94。采用 Cronbach's alpha 系数评估内部一致性，疼痛、日常生活活动（ADL）和运动/娱乐功能的信度可接受（范围为 0.86-0.93）；然而，症状和 QoL 的内部一致性较弱。H-KOOS 中测量相似结构的各领域之间存在中度至高度相关性（r=0.35-0.6），表明良好的收敛结构效度。疼痛的效应量（ES）和标准化反应均值（SRM）为 0.9 和 0.8，运动/娱乐功能为 0.66 和 0.2，ADL、QoL 和症状子量表为 0.2 和 0.2，表明反应度较大。
印地语版 KOOS 是一种有效的、可靠的、敏感的膝关节骨关节炎评估工具，具有最小的天花板和地板效应。
