Abstract

This study focuses on understanding the consequences of Anterior Cruciate Ligament (ACL) injuries and their rehabilitation effectiveness by comparing muscle forces in planned and unplanned movements between healthy and reconstructed ACL limbs. 3D motion and ground reaction force data were collected from high-performance athletes who underwent reconstructive surgery and performed a sidestep cut. Results showed lower limbs with a reconstructed ACL had lower contributions of the vasti to anterior accelerations. Furthermore, athletes performing unanticipated manoeuvres had a greater gastrocnemii contribution to posterior accelerations, indicating a higher mechanical ACL load. These findings highlight the importance of optimizing ACL rehabilitation, as muscle function may not be fully restored, potentially contributing to the recurrence of ACL injuries
