Translation and validation of the simplified Chinese version of the anterior cruciate ligament-return to sport after injury (ACL-RSI).
Knee Surgery, Sports Traumatology, Arthroscopy 2018 October
PURPOSE: The aim of this study is to obtain a translation and adaptation of the anterior cruciate ligament-return to sport after injury (ACL-RSI) into simplified Chinese and validate the simplified Chinese version.
METHODS: Translation and adaptation were performed according to the guidelines of the American Academy of Orthopaedic Surgeons Outcome Committee. A total of 122 patients who were diagnosed with an ACL injury and underwent primary arthroscopic anterior cruciate ligament reconstruction (ACLR) between 2015 and 2016 were included in this study. The simplified Chinese version of the ACL-RSI (SC-ACL-RSI), Knee injury and Osteoarthritis Outcome Score (KOOS), Lysholm score and International Knee Documentation Committee (IKDC) subjective knee form were completed. Psychometric evaluations included score distribution, internal consistency, test-retest reliability, and construct and discriminant validity.
RESULTS: SC-ACL-RSI scores exhibited a normal distribution without ceiling and floor effects. Internal consistency was high (Cronbach's alpha = 0.94). The intraclass correlation coefficient was 0.98, indicating excellent test-retest reliability. SC-ACL-RSI scores were correlated with all KOOS subscales (r = 0.30 to 0.69, p < 0.001), the IKDC subjective knee form (r = 0.46, p < 0.001) and the Lysholm score (r = 0.56, p < 0.001). The mean scores between patients who returned to the same preinjury level of sport (65.1 ± 14.3) and those who could not return to the same level (51.0 ± 15.0) were significantly different (p < 0.001).
CONCLUSIONS: The SC-ACL-RSI is a reliable and valid instrument to evaluate the psychological impact of a patient returning to sport after ACLR. It is important to evaluate patients' ability to return to sport after an ACL injury. The information provided by the SC-ACL-RSI will affect decisions regarding treatment and rehabilitation plans, which are more likely to influence clinical outcomes.
LEVEL OF EVIDENCE: II.
