Summary
The study showed that the HIP-RSI score, score that previously allowed to highlight the importance of psychological factors in the return to sport after arthroscopic treatment of acetabular conflict, is a reproductible and valid tool to assess the psychological readiness to return to sport in active patients who had surgical repair of a proximal hamstring avulsion, as the score had good discrimina

Abstract
Purpose
The HIP-Return to Sport after Injury (HIP-RSI) score highlights the importance of the psychological factor in the return to sport (RTS) following arthroscopic treatment of femoroacetabular impingement.
The goal of this study was to evaluate the reproducibility and validity of the HIP-RSI score for the assessment of the psychological readiness to RTS after surgical repair of a proximal hamstring avulsion in active patients, and the ability of the score to predict the return to the preinjury sport at postoperative 9 months.
Study Design:
Case Control Study
Method
Patients who underwent primary surgical repair of a proximal hamstring avulsion between June 2022 and November 2023 were included in this prospective cohort study. All patients completed the HIP-RSI score at postoperative 4 and 9 months. The HIP-RSI score was compared to the Parisian Hamstring Avulsion Score (PHAS) for validation using the Pearson’s correlation coefficient. The discriminant and predictive abilities of the HIP-RSI score were also estimated. A test-retest was used to assess the score’s reliability, and internal consistency was assessed using the Cronbach alpha coefficient.
Results
A total of 84 patients (38 women and 46 men, mean age 48.7 ± 12.7 years old at surgery) were included. The HIP-RSI score was moderately correlated to the PHAS score (r = 0.46 [0.27 – 0.6]). The Intraclass Correlation Coefficient (ICC) was 0.89 (95% IC: 0.75–0.96), indicating good reliability of the score over time. The discriminant ability of the HIP-RSI score was good as it was significantly higher in the RTS group than in patients who did not return to their preinjury sport. Furthermore, the predictive ability to identify patients who would return to their pre-injury sport at postoperative 9 months was good (AUC = 0.76). At an optimal cut-off value of 51.7, the HIP-RSI score at 4 months had a sensitivity of 69% and a specificity of 77% with a Youden index of 0.46. The internal consistency suggested redundancy among the score items (alpha coefficient = 0.97).
Conclusion
The HIP-RSI score is a valid, reproducible tool to assess the psychological readiness to RTS in active patients who undergo surgical repair of a proximal hamstring avulsion. This score, with a cut-off of 51.7 at postoperative 4 months, could help predict patients who will return to sport with a sensitivity of 69% and a specificity of 77%.
