Abstrakt: | The modified International Knee Documentation Committee Subjective Knee Form (Pedi- IKDC) is a widely used patient-reported tool ranging on a scale from 0 to 100. We aimed to translate Pedi- IKDC into Danish and assess its reproducibility and responsiveness in children with knee disorders. The translation complied with the international guidelines. Reproducibility was assessed in 53 children (15 years) responding Pedi- IKDC at baseline and after 3-14 days. For analysis of responsiveness, 94 children (15 years) responded Pedi- IKDC again after 3 months. Test-retest reliability was excellent. Intraclass correlation coefficient was 0.9, standard error of measurement was 4.1 points, and smallest detectable change ( SDC) was 11.3 points. Evaluating responsiveness as a large effect was found in children reporting improvement compared with children reporting deterioration. The change score was correlated to the external anchor Global Rating Scale consisting of 15 answers from −7 'A very great deal worse' to +7 'A very great deal better,' with a Spearmen's rho of 0.45 ( P > 0.001). The minimal clinically important changes was 12.0. In conclusion, excellent test-retest reproducibility was found at group level, but at individual level the SDC was high. The Pedi- IKDC showed adequate responsiveness and is suitable for assessing improvement or deterioration in children with knee disorders. [ABSTRACT FROM AUTHOR] |
