The aim of this study was to translate to Spanish the patellofemoral pain and osteoarthritis subscale of the knee injury and osteoarthritis outcome score (KOOS-PF) and validate this Spanish version of a disease-specific patient-reported outcome measure (PROM) for patellofemoral pain.
The KOOS-PF was translated to Spanish and sixty patients with patellofemoral pain and/or osteoarthritis accepted to complete the questionnaire. 1-week later 58 patients answered the questions again for the test-retest reliability validation and finally 55 patients completed 1-month later for the responsiveness assessment. The Spanish version showed very good internal consistency (Cronbach's alpha: 0.93) and test-retest reliability (intraclass correlation coefficient: 0.82). Responsiveness was confirmed, showing a strong correlation with the global rating of change (GROC) score (r 0.64). The minimal detectable change was 11.1 points, the minimal important change was 17.2 points, and there were no floor or ceiling effects for the score.
本研究旨在将膝关节损伤和骨关节炎结局评分（KOOS-PF）中的髌股疼痛和骨关节炎亚量表翻译为西班牙语，并验证该髌股疼痛专用患者报告结局测量量表（PROM）的西班牙语版本。
KOOS-PF 被翻译为西班牙语，共有 60 名髌股疼痛和/或骨关节炎患者接受了问卷调查。1 周后，58 名患者再次回答了这些问题，以验证重测信度，最后有 55 名患者在 1 个月后完成了问卷，以评估反应度。该西班牙语版本显示出非常好的内部一致性（Cronbach's alpha：0.93）和重测信度（组内相关系数：0.82）。反应度得到了确认，与整体变化评分（GROC）呈强相关（r=0.64）。最小可检测变化为 11.1 分，最小有意义变化为 17.2 分，且该评分无地板或天花板效应。
