Anterior cruciate ligament (ACL) reconstruction in young male athletes is typically performed using various methods, including hamstring tendon autograft (HT), patellar tendon autograft (PT), or allograft (QT). However, there is no consensus on the optimal graft choice for ACL reconstruction. This study aimed to compare the lower limb biomechanics in young male athletes following ACL reconstruction using allograft, patellar tendon autograft, and hamstring tendon autograft.
Methodology: This study compared the biomechanics of directional changes in young athletes with unilateral ACL reconstruction using hamstring autograft (HT), patellar tendon autograft (PT), and allograft (QT). The participants were in the active rehabilitation phase and performed change-of-direction movements (CS, CR, and CF). Biomechanical assessments were conducted using a three-dimensional motion analysis system with eight cameras and two analog force plates. Data were analyzed using SPSS version 26, and multivariate analysis of covariance (MANOVA) was employed to evaluate intergroup differences at a significance level of 0.05.
Results: MANOVA revealed a significant difference in vertical ground reaction force (GRF) between the HT, PT, and QT groups (p=0.021), independent of movement direction (p=0.984). Other force variables, such as internal-external and anterior-posterior GRF, loading rate, and hip and knee flexion/extension torques, showed no significant differences between groups or group-direction interactions (p>0.05). However, adduction/abduction and internal/external rotation torques of the hip and knee demonstrated significant dependence on movement direction (p<0.001 and p=0.032). Additionally, hip and knee adduction/abduction and internal/external rotation angles exhibited significant intergroup and directional interactions (p=0.001 and p=0.002 for the hip and p=0.001 for the knee). In contrast, no significant differences were observed in other angles, such as knee flexion/extension and internal/external rotation, across groups or movement directions.
Conclusion: Overall, the findings indicate reduced knee and hip loading in adolescents following ACL reconstruction. Moreover, athletes with PT or QT grafts experienced greater deficits in knee and hip performance during rehabilitation compared to HT grafts. Therefore, graft choice in ACL reconstruction should be tailored to the individual conditions of athletes and planned to optimize movement biomechanics, minimize the risk of graft re-rupture, and reduce complications at the donor site.
