About

The anterior cruciate ligament (ACL) injury is common in athletes aged 18 to 35. ACL reconstruction (ACLR) aims to restore knee stability in the process of returning to sports. Post-surgical rehabilitation focuses on optimizing biomechanical parameters, with neuromuscular and functional tests assessing muscle strength, proprioception, and dynamic stability. Isokinetic allows the measurement of muscle strength symmetry and proprioception, while the single-leg hop and landing tasks assess functional stability and are predictive of sports resumption and injury prevention. Despite progress, concerns remain about neuromuscular factors impacting knee stability, especially during landings, which can increase the risk of secondary ACL injuries.

This study proposes examining knee strength and proprioception using isokinetic dynamometry, alongside biomechanical assessments from functional tests, to explore their relationship to biomechanical features during landings, at 6-to-12 months post-ACL reconstruction. The hypothesis is that better muscle strength and proprioception correlate with improved knee control during landing tasks.
