背景和目的：国际膝关节文献委员会制定了膝关节主观量表，用于测量因各种膝关节疾病接受治疗的患者的症状、功能和体育活动的变化。虽然以前的研究已经证明了信度和效度的形式，它的反应没有得到评估。本研究的目的是确定国际膝关节文献委员会膝关节主观量表的反应性。证据等级：1.方法：参与国际膝关节文献委员会膝关节主观量表原始确认研究的患者完成了该表格，并进行了7-平均1.6年（范围，0.5-2.3年）后，变化量表的总体等级从非常差到非常好。分析包括计算标准化反应平均值和国际膝关节文献委员会膝关节主观形式评分的平均变化，并与患者对整体变化量表评分变化的感知进行比较。此外，受试者操作特征曲线绘制，以确定最好的区分患者谁从那些谁没有改善的分数的变化。结果：整体标准化反应平均值为0.94，这被认为是大的。除了轻微恶化或无变化的患者外，国际膝关节文献委员会主观膝关节形式评分的平均变化与患者感知的总体变化评级相比符合预期（严重恶化，-15.1;稍差，-8.4;稍差，20.6;无变化，10.7;稍好，5.9;稍好，18.1;大大好，38.7）。受试者工作特征曲线分析显示，11.5分的变化评分具有最高的敏感性，和20.5分的变化评分具有最高的特异性，以区分那些谁是或没有改善.Conclusion：国际膝关节文献委员会的主观膝关节形式是一个反应措施的症状，功能和运动活动的患者与各种膝关节的条件。
Background and Purpose: The International Knee Documentation Committee Subjective Knee Form was developed to measure change in symptoms, function, and sports activity in patients treated for a variety of knee conditions. Although previous research has demonstrated reliability and validity of the form, its responsiveness has not been evaluated. The purpose of this study was to determine responsiveness of the International Knee Documentation Committee Subjective Knee Form.Study Design: Cohort study (diagnosis); Level of evidence, 1.Methods: Patients who participated in the original validation study for the International Knee Documentation Committee Subjective Knee Form completed the form and a 7-level global rating of change scale that ranged from greatly worse to greatly better after a mean of 1.6 years (range, 0.5-2.3 years). Analyses included calculation of the standardized response mean and mean change in International Knee Documentation Committee Subjective Knee Form score compared to the patient's perception of change on the global rating of change scale. In addition, a receiver operating characteristic curve was plotted to determine the change in score that best distinguished patients who improved from those who did not.Results: The overall standardized response mean was 0.94, which is considered large. With the exception of those who were slightly worse or unchanged, the mean change in the International Knee Documentation Committee Subjective Knee Form score compared to the patients' perceived global ratings of change was as expected (greatly worse, -15.1; somewhat worse, -8.4; slightly worse, 20.6; no change, 10.7; slightly better, 5.9; somewhat better, 18.1; greatly better, 38.7). The receiver operating characteristic curve analysis revealed that a change score of 11.5 points had the highest sensitivity, and a change score of 20.5 points had the highest specificity to distinguish between those who were or were not improved.Conclusion: The International Knee Documentation Committee Subjective Knee Form is a responsive measure of symptoms, function, and sports activity for patients with a variety of knee conditions.
