Evaluación funcional de la rodilla en reconstrucción del ligamento cruzado anterior al retorno al deporte: validación de la escala ACL-RSI modificada

Introduction

Reconstruction of the anterior cruciate ligament (ACL) can allow the athlete to return to the level prior to the injury, despite the success of the procedure, a high percentage does not achieve it due to physical and psychological factors. One of the most used methods for the subjective evaluation of knee functionality after resumption of physical activity is the ACL-RSI scale (Anterior Cruciate Ligament – Return to Sport injury).

Objective

To evaluate the functionality of the knee in the return to sport in patients with RLCA and to validate the modified ACL-RSI scale in athletes with recreational activity.

Materials and methods

Translation and re-translation of the modified ACL-RSI scale was performed, selected words on the scale were culturally adapted, and it was applied to 44 recreational athletes in the 9-month postoperative ACL with return to physical activity. performed descriptive analysis of the results, exploratory factorial analysis of the scale and application of Cronbach's alpha to assess the reliability of the scale.

Results

The mean age was 33.7 years. Cronbach's alpha obtained for the modified ACL-RSI scale was 0.928. The means of the answers show functional results between 4 and 6 on a scale of 10 in terms of physical and psychological factors related to RLCA, the worst result was related to jumping during sports activity (mean 4.1).

Conclusions

The modified, culturally adapted ACL-RSI scale is valid and applicable to assess knee function in RLCA on return to sport. The functional results of the RCLA show means less than 6 for all items, both physical and psychological.
