The International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form is a knee-specific measure developed for adults. Its usefulness in children is not established. This study describes how children interpret IKDC items, identifies sources of response errors, and provides suggestions for modification. Cognitive interviews were conducted in 30 children with a primary knee injury, purposefully sampled based on age and gender. Most children could not recall their injury date or symptoms 4 weeks after injury. All reported problems interpreting directions; half noted item timeframes were unclear and did not realize all questions pertained to their injured knee. Seventy percent read only the first half of a question, missing subtle differences between items. Children had difficulty comprehending the following concepts: strenuous/moderate activity, pivoting, locking, giving way, significant pain/swelling, and knee catching. Examples to describe activity levels either did not apply (e.g. housework) or were ranked differently by children. Younger children had difficulty using five-point responses. The two most difficult items were assessment of current and prior function. Children found the IKDC Subjective Knee Evaluation Form difficult to comprehend and to answer. Modifications to directions, item formatting, and definitions are needed to ensure comprehensibility and validity.
国际膝关节文献委员会（IKDC）主观膝关节评估表是一种专为成年人开发的膝关节特定测量工具，其在儿童中的有效性尚未确定。本研究描述了儿童如何解释 IKDC 项目，确定了回答错误的来源，并提供了修改建议。在 30 名患有原发性膝关节损伤的儿童中进行了认知访谈，根据年龄和性别进行了有针对性的抽样。大多数儿童在受伤后 4 周无法回忆起受伤日期或症状。所有报告都表示在解释说明时存在问题，一半的人认为项目的时间范围不清楚，并且没有意识到所有问题都与他们受伤的膝盖有关。70%的儿童只阅读了问题的前半部分，忽略了项目之间的细微差异。儿童难以理解以下概念：剧烈/适度活动、旋转、锁定、失稳、明显疼痛/肿胀和膝盖卡顿。用来描述活动水平的例子要么不适用（例如家务），要么被儿童以不同的方式进行排名。年幼的儿童难以使用五分制的回答。两个最困难的项目是对当前和以前功能的评估。儿童发现 IKDC 主观膝关节评估表难以理解和回答。需要对说明、项目格式和定义进行修改，以确保理解和有效性。
