The International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form (IKDC Knee Form) is a valid, reliable, and responsive measure of knee-related symptoms, function, and sports activities in adults. Despite the incidence of knee injuries in younger individuals, the measurement characteristics of the IKDC Knee Form have not been established. Hypothesis/
The purpose of this study was to investigate the validity and internal consistency of the IKDC Knee Form in pediatric, adolescent, and young adult patients with a variety of knee conditions. The authors hypothesized that the IKDC Knee Form would be a valid and consistent measure of knee function in these age groups.
Cohort study (diagnosis); Level of evidence, 2.
The IKDC Knee Form and Pediatric Quality of Life Inventory 4.0 Generic Core Scales (PedsQL) physical functioning component were administered to 673 individuals between 6 and 18 years of age. The internal consistency and validity of the IKDC Knee Form were determined for the entire cohort and for age group cohorts (pediatric, 6-12 years; adolescent, 13-15 years; young adult, 16-18 years) using the PedsQL physical functioning component for comparison.
The results were similar across all age groups. In the original format, internal consistency was high and factor analysis showed a single, dominant component underlying the item responses for each age group. Items 2, 3, and 6 may contribute to measurement error in young individuals. Correlation between the IKDC Knee Form and PedsQL physical functioning component score was moderately high for the entire cohort (r = .83) and for all age groups (pediatric, r = .84; adolescent, r = .84; young adult, r = .79).
In its current form, the IKDC Knee Form is a valid and consistent knee-specific measure of symptoms, function, and sports activity in individuals between the ages of 6 and 18 years with a variety of knee problems. Further work is needed to establish the reliability and responsiveness of the IKDC Knee Form for this age group.
国际膝关节文献委员会（IKDC）主观膝关节评估表（IKDC 膝关节表）是一种有效、可靠且能反映成人膝关节相关症状、功能和运动活动的工具。尽管年轻人中也存在膝关节损伤，但 IKDC 膝关节表的测量特征尚未确定。
假设/目的：本研究旨在探讨 IKDC 膝关节表在各种膝关节疾病的儿科、青少年和年轻成年患者中的有效性和内部一致性。作者假设 IKDC 膝关节表在这些年龄组中是一种有效的、一致的膝关节功能测量工具。
队列研究（诊断）；证据水平，2 级。
673 名 6 至 18 岁的个体接受了 IKDC 膝关节表和儿科生活质量量表 4.0 通用核心量表（PedsQL）身体功能成分的评估。通过与 PedsQL 身体功能成分进行比较，确定 IKDC 膝关节表在整个队列以及年龄组队列（儿科，6-12 岁；青少年，13-15 岁；年轻成人，16-18 岁）中的内部一致性和有效性。
所有年龄组的结果相似。在原始格式中，内部一致性较高，因子分析显示，每个年龄组的项目反应都有一个单一的主导成分。对于年轻人，项目 2、3 和 6 可能会导致测量误差。整个队列（r =.83）和所有年龄组（儿科，r =.84；青少年，r =.84；年轻成人，r =.79）中，IKDC 膝关节表与 PedsQL 身体功能成分得分之间的相关性均较高。
在目前的形式下，IKDC 膝关节表是一种有效的、一致的膝关节特异性工具，可用于评估 6 至 18 岁有各种膝关节问题的个体的症状、功能和运动活动。需要进一步研究以确定 IKDC 膝关节表在该年龄组的可靠性和反应性。
