The International Knee Documentation Committee (IKDC) and Anterior Cruciate Ligament - Quality of Life Questionnaire (ACL-QOL) are frequently used patient-reported instruments designed for individuals with anterior cruciate ligament reconstruction (ACL-R). To evaluate responsiveness and determine minimal important change (MIC) for the Persian-version of IKDC and ACL-QOL in athletes with ACL-R following physiotherapy intervention. One hundred athletes with ACL-R, undergoing 16-week physiotherapy completed IKDC and ACL-QOL at weeks 4 and 20 post ACL-R. Participants also rated their overall changes on a 7-point global rating of change at follow-up. Responsiveness was evaluated using the receiver operating characteristics (ROC) curve and correlation analysis. In addition, the minimal important change (MIC) was determined on the ROC curve. Acceptable responsiveness was reached by the IKDC and most of the subscales of ACL-QOL (area under the ROC curve (AUC) of 0.72-0.79). Also, the subscale of Lifestyle issues of ACL-QOL (AUC of 0.81 (95% CI = 0.72-0.89) and the overall of ACL-QOL (AUC of 0.87 (95% CI = 0.80-0.93) showed the good level of responsiveness. The MIC scores of IKDC and the Overall ACL-QOL were determined 25 and 26 points, respectively. The IKDC and ACL-QOL questionnaires have adequate responsiveness and are able to measure the change in athletes with ACL-R following a 16-week physiotherapy intervention.
