The Kujala score is a useful diagnostic tool to evaluate patellofemoral pain syndrome (PFPS). However, no validated Indonesian version of the Kujala score has been available.
To develop and validate an Indonesian version of the Kujala score.
Cohort study (diagnosis); Level of evidence, 3.
This was a cross-sectional study to develop an Indonesian version of the Kujala score by using a forward-backward translation protocol. The resulting questionnaire was given to 51 patients diagnosed with PFPS. The validity of the questionnaire was evaluated by correlating the final score with the Indonesian version of the 36-Item Short Form Health Survey (SF-36). Reliability was measured by evaluating the internal consistency (Cronbach alpha) and test-retest reliability (intraclass correlation coefficient [ICC]).
The Indonesian version of the Kujala score had a positive correlation with the physical components of the SF-36. The internal consistency was fairly high (α = .74), and the test-retest reliability was excellent (ICC, 0.996).
The Indonesian version of the Kujala score was proven to be a valid and reliable tool to diagnose PFPS. Future epidemiological studies could implement this score to find the prevalence of PFPS in Indonesia. Further, ensuing studies could explore the application of this scoring system in posttreatment and postoperative settings.
库贾拉评分是评估髌股疼痛综合征（PFPS）的一种有用的诊断工具。然而，目前尚无经过验证的印尼语版库贾拉评分。
开发并验证印尼语版的库贾拉评分。
队列研究（诊断）；证据等级，3级。
这是一项横断面研究，采用前后翻译协议来开发印尼语版的库贾拉评分。将生成的问卷发给51名被诊断为PFPS的患者。通过将最终得分与印尼语版36项简短健康调查（SF-36）进行关联来评估问卷的有效性。通过评估内部一致性（克朗巴赫α系数）和重测信度（组内相关系数[ICC]）来衡量信度。
印尼语版的库贾拉评分与SF-36的身体成分呈正相关。内部一致性相当高（α = 0.74），重测信度极佳（ICC，0.996）。
印尼语版的库贾拉评分被证明是诊断PFPS的有效且可靠的工具。未来的流行病学研究可以采用这个评分来找出印尼PFPS的患病率。此外，后续研究可以探索这个评分系统在治疗后和术后环境中的应用。
