Anterior cruciate ligament—Return to sport after injury scale brief version after ACL reconstruction: Persian translation, cross‐cultural adaptation and validation

Abstract

AbstractPurposeThe purpose of this study is to analyze the short anterior cruciate ligament return to sport after injury (ACL‐RSI) (Persian) version's cultural adaption and validity.MethodsTo assess test–retest reliability, 102 participants were filled out the short ACL‐RSI(Per) scale 6 months or more after ACLR surgery. Internal consistency (Cronbach's alpha), test–retest reliability (intraclass correlation coefficients), construct validity (Pearson's r) and sensitivity (floor/ceiling effect) were determined. In addition, patient completed other relevant measures such as Lysholm scores, the hospital for special surgery ACL satisfaction survey (HSS ACL‐SS), the visual analogue scale (VAS) of pain and patient's satisfaction, the Tegner activity score (TAS), the single assessment numeric evaluation (SANE) and the Cincinnati Knee Rating System (CKRS).ResultsThe short ACL‐RSI(Per) scale showed high internal consistency (Cronbach's alpha = 0.91) and test–retest reliability (ICC = 0.923). Significant correlations between short ACL‐RSI(Per) and other scales supported validity. There was a statistically significant connection between the short ACL‐RSI(Per) and the following outcomes: HSS ACL‐SS (r = 0.698, p < 0.001), VAS pain (r = 0.356, p < 0.001), CKRS (r = 0.644, p < 0.001), TAS (r = 0414, p < 0.001), Lysholm score (r = 0.467, p < 0.001) and SANE score (r = 0.536; p < 0.001). In addition to a satisfactory ceiling impact (15%), a sizeable floor effect (16.7%) was also seen.ConclusionThe short ACL‐RSI(Per) scale is a reliable and valid tool for assessing psychological readiness for return to sport after ACL reconstruction in Persian.Level of EvidenceIII.
