Abstract
To validate and assess the cross-sectional adaptation of the modified Cincinnati knee rating system (MCRKS) Persian translation. To assess test-pretest reliability, 102 participants were asked to fill out the MCRKS (Per) scale after anterior cruciate ligament (ACL) reconstruction surgery. Internal consistency (Cronbach's <i>α</i>), reliability (intraclass correlation coefficients), construct validity (Pearson's <i>r</i>) and sensitivity (floor/ceiling effect) were determined. In addition, patients completed other relevant measures as the ACL return to sports after injury (ACL-RSI) survey, hospital for special surgery ACL satisfaction survey (HSS ACL-SS), visual analogue scale (VAS) of pain and patient's satisfaction, Tegner activity score (TAS), single assessment numeric evaluation, and Lysholm score. Using MCRKS (Per), the internal consistency (Cronbach's <i>α</i>) was 0.9 (if item deleted: 0.81-0.86); the construct validity (Pearson's <i>r</i>) varied between -0.50 (for VAS pain scale) and 0.79 (for Lysholm score); the reliability (ICC value) varied between 0.82 and 0.97; furthermore, no ceiling or floor effect was present. The MCRKS (Per) has adequate measurement properties and is considered a valid, reliable and sensitive instrument which can identify clinical outcomes after ACLR surgery. Level IV.
