title: Translation and cross-cultural adaptation of the anterior cruciate ligament-return to sport after injury (ACL-RSI) scale into Turkish.
abstract: OBJECTIVE
  To translate and culturally adapt the anterior cruciate ligament-return to sport after injury (ACL-RSI) scale into Turkish (ACL-RSI-Tr) and examine and evaluate the psychometric properties of the Turkish version in individuals who have undergone anterior cruciate ligament (ACL) reconstruction.
  
  
  METHODS
  The ACL-RSI was forward- and back-translated, culturally adapted and validated on ninety-three Turkish individuals who had undergone ACL reconstruction (5 females, 88 males; age 28.7 ± 8.6 years; body mass 80.1 ± 13.9 kg; height 178.8 ± 6.9 cm; body mass index 25.0 ± 3.7 kg/m2). All patients completed the translated ACL-RSI, Tampa Scale of Kinesiophobia (TSK), Knee injury and Osteoarthritis Outcome Score (KOOS) and International Knee Documentary Committee (IKDC) and Lysholm questionnaires. We then analysed the internal consistency, reliability and validity of the newly formed ACL-RSI-Tr scale.
  
  
  RESULTS
  The ACL-RSI-Tr showed good internal consistency (Cronbach's alpha 0.86) and test-retest reliability (ICC 0.92) and was significantly correlated with the KOOS 'quality of life' (r = 0.58, p < 0.002), 'symptoms and stiffness' (r = 0.35, p = 0.001), 'pain' (r = 0.49, p < 0.001), 'sports' (r = 0.44, p < 0.001) and 'daily life' (r = 0.42, p < 0.001) subscales. The ACL-RSI-Tr also correlated significantly with the TSK (r = - 0.45, p < 0.001), Lysholm (r = 0.45, p < 0.001) and IKDC (r = 0.44, p < 0.001) scores.
  
  
  CONCLUSIONS
  The Turkish version of the ACL-RSI scale was valid, discriminant, consistent and reliable in patients who had undergone ACL reconstruction. This score could be useful to evaluate the effect of psychological factors on return to sport following ACL surgery.
