The ALR-RSI score can be used to evaluate psychological readiness to return to sport after acute Achilles tendon tear

Abstract

Purpose: The return to sport is one of the main goals following Achilles tendon tear repair. Several psychological factors influence the return to sport after a sports injury. The traditional tools to assess the return to sport do not take into account psychological factors. The ankle ligament reconstruction-return to sport injury (ALR-RSI), validated for ankle instability, is a score to evaluate psychological readiness to return to sport. The goal of this study was to validate the ALR-RSI score for the assessment of the readiness to return to sport after Achilles tendon repair. Methods: The ALR-RSI score, adapted from the anterior cruciate ligament-return to sport injury (ACL-RSI) score used following knee ligament reconstruction, was validated according to the international COSMIN methodology. Patients operated for Achilles tendon repair responded to the questionnaire during the rehabilitation period. The EFAS, FAAM and VISA-A scores were used as reference questionnaires. Results: A total of 50 patients were included. The ALR-RSI score was strongly (r > 0.5) correlated to the EFAS score: r = 0.68 [0.50–0.80] the FAMM sport score: r = 0.7 [0.52–0.84] the FAAM AVQ score (r = 0.6 [0.35–0.78]), and the VISA-A score (r = 0.54 [0.26–0.76]). The discriminant validity was good with the ALR-RSI, which was significantly lower in the patients that did not return to sport: 60.7 (40–81.4) compared to those that did: 83.2 (64.3–100) p = 0.001. Reproducibility was excellent with an intra-class correlation coefficient ρ of 0.99 [097–1.00]. The internal consistency was excellent (alpha coefficient = 0.95). Conclusion: The ALR-RSI score provides a valid, reproducible assessment of the psychological readiness to return to sport in patients who undergo surgical Achilles tendon suture repair. Level of evidence: III.
