Return-to-sport (RTS) decisions following hamstring injuries and anterior cruciate ligament (ACL) reconstruction remain challenging due to high re-injury rates and suboptimal recovery outcomes. This study evaluates the predictive validity of functional performance tests and the influence of psychological factors on RTS outcomes. A mixed-methods approach was employed, combining quantitative assessments (Iso-Kinetic strength testing, single-leg hop tests, and sprint analysis) with qualitative insights from semi-structured interviews. Participants included elite athletes aged 18–35 years recovering from hamstring injuries or ACL reconstruction. Results demonstrated high predictive validity for functional tests, with Iso-Kinetic strength testing (AUC = 0.89) and single-leg hop tests (AUC = 0.91) significantly correlating with successful RTS. Psychological factors, including fear of re-injury (r = -0.62) and confidence (r = 0.71), were also critical determinants of RTS outcomes. Qualitative themes highlighted the role of motivation and support systems in RTS decisions. This study underscores the importance of integrating physical and psychological assessments in RTS protocols to optimize recovery and reduce re-injury rates.
