Objective: To translate and evaluate the test-retest reliability, internal consistency and construct validity of the Persian version of the IKDC questionnaire in Iranian patients after ACL and meniscal operations.

Materials & Methods: After translation based on the Quality Of Life Assessment protocol, the IKDC, KOOS and SF-36 Health Survey were administered to a sample of 101 patients underwent for ACL and meniscal operations. The test-retest reliability was tested by use of an Intra-class Correlation Coefficient, the internal consistency by a Crohnbach’s alpha and the construct validity were tested by correlating the IKDC scores with KOOS subscales including pain, symptoms, ADL, recreations and sport activity, Quality Of Life and the physical and mental component summaries and the SF-36 Health Survey. In addition, the construct validity was measured by Pearson and Spearman correlation coefficient parameters.

Results: A high test-retest reliability score was found with an ICC of 0. 99. The Internal consistency was as 0. 90. A moderate to good correlation was obtained between the IKDC total score and KOOS subscales, including pain (r=0.66, P<0.001), symptoms (r=0.55), ADL (r=0.68), sport and recreation activities (r=0.60) and Quality Of Life (r=0.50). A good correlation was found between the total scores of the IKDC and physical component summary (r=0.70) along with another fair association between the mental component summaries of the SF-36 Health Survey (r=0.44).

Conclusion: Persian version of the IKDC is a reliable and valid instrument for designing any assessment or rehabilitation program in Iranian patients after ACL and meniscal Surgery.
