No questionnaire is currently available for use in patients with anterior cruciate ligament (ACL) injuries in an Indonesian population. The most-used questionnaire in clinical research for these patients is the International Knee Documentation Committee (IKDC) Subjective Knee Form, as its psychometric properties are considered to be excellent.
To translate the IKDC into Indonesian and assess its validity for use in Indonesian-speaking patients with ACL injuries.
Cohort study (diagnosis); Level of evidence, 2.
After a forward-and-backward translation procedure and cross-cultural adaptation, the validity and reliability of the questionnaire were investigated. The responses of ACL injury patients on 3 questionnaires, the Indonesian-IKDC (I-IKDC), 36-Item Short Form Health Survey, and Kujala Anterior Knee Pain Scale, were compared. Following consensus-based standards for the selection of health measurement instruments guidelines, construct validity, test-retest reliability, internal consistency, floor and ceiling effects, and measurement error were determined. The Bland-Altman method was used to explore absolute agreement.
Of 253 ACL injury patients, 106 (42%) responded to the invitation. Construct validity was considered good, as all predefined hypotheses on correlations between the I-IKDC and other scores were confirmed. Reliability proved excellent, with a high test-retest correlation (intraclass correlation coefficient = 0.99). Bland-Altman analyses showed no systematic bias between test and retest. Internal consistency was good (Cronbach α = .90). There were no floor or ceiling effects. Standard error of measurement was 2.1, and the minimal detectable change was 5.8 at the individual level and 0.7 at the group level.
The I-IKDC, as developed, appeared to be a good evaluation instrument for Indonesian patients with ACL injuries.
目前尚无适用于印度尼西亚人群中前交叉韧带（ACL）损伤患者的问卷。临床研究中针对这些患者最常用的问卷是国际膝关节文献委员会（IKDC）主观膝关节表，因为其心理测量特性被认为非常出色。
将IKDC翻译成印尼语，并评估其在说印尼语的ACL损伤患者中使用的有效性。
队列研究（诊断）；证据等级，2级。
经过正向和反向翻译程序以及跨文化改编后，对问卷的有效性和可靠性进行了调查。比较了ACL损伤患者对3种问卷的回答，即印尼语IKDC（I-IKDC）、36项简短健康调查和库亚拉前膝痛量表。根据基于共识的健康测量工具选择标准指南，确定了结构效度、重测信度、内部一致性、地板效应和天花板效应以及测量误差。采用布兰德-奥特曼方法探讨绝对一致性。
在253例ACL损伤患者中，106例（42%）回应了邀请。结构效度被认为良好，因为关于I-IKDC与其他评分之间相关性的所有预定义假设均得到证实。信度证明非常出色，重测相关性很高（组内相关系数 = 0.99）。布兰德-奥特曼分析显示测试和重测之间没有系统偏差。内部一致性良好（Cronbach α = 0.90）。没有地板效应或天花板效应。测量的标准误差为2.1，个体水平的最小可检测变化为5.8，组水平为0.7。
所开发的I-IKDC似乎是评估印度尼西亚ACL损伤患者的良好工具。
