Summary

The simplified Chinese ACL-RSI (ACL-RSI-Cn) was a validated, reliable, and convenient tool in evaluating psychological factors related to returning to sport after ACL reconstruction.

Abstract

Purpose

To translate and cross-culturally adapt the anterior cruciate ligament-return to sport after injury (ACL-RSI) into simplified Chinese [ACL-RSI (Cn)].

Method

The translation, cross-culturally adaptation, and validation of the ACL-RSI was performed according to international guidelines. A total of 112 patients of ACL reconstruction participated in this study. All were capable of competitive sports before injury and completed the Knee Injury and Osteoarthritis Outcome (KOOS), the International Knee Documentation Committee (IKDC), the Tampa Scale of Kinesiophobia (TSK), and the Tegner activity score. Forty eight patients completed the ACL-RSI (Cn) twice within two weeks. The validity was tested using seven premade hypotheses. Internal consistency, reliability, and measurement error was assessed.

Result:
At meanly 15.6 months postoperative, 81 (72.3%) patients returned to sport, with 57 (50.9%) to competitive sport and 24 (21.4%) to recreational sport. Thirty one (27.7%) patients didn't return to any sport, with 19 (17.0%) still had plan to return and 12 (10.7%) gave up sport. The ACL-RSI (Cn) demonstrated excellent validity with all hypotheses confirmed. The outcome of ACL-RSI (Cn) was strongly correlated the KOOS subscale quality of life (r=0.66, p<0.001), the TSK (r=-0.678, p<0.001), the Tegner score (r=0.695, p<0.001). There was statistic difference between cases returned (68.6 ± 10.1) and didn't return to sport (41.3 ± 17.7), p<0.001; between cases returned to competitive (71.1 ± 8.9) and recreational sport (62.9 ± 10.5), (P=0.002); between cases who planned to return (50.7 ± 14.1) and gave up sport (26.5 ± 11.7), (P<0.001). The internal consistency (Cronbach's a=0.96) and test-retest reliability [intra-class correlation coefficient (ICC) =0.90] was excellent. The measurement error, floor and ceiling effect was satisfactory. Administration time was 3.2 minutes, and no item was missed.

Conclusions

The ACL-RSI (Cn) scale was confirmed as a valid, reliable, and feasible tool in evaluating psychological factors influencing return to sport.
