Biomechanical Analysis After Anterior Cruciate Ligament Reconstruction at the Return-to-Sport Time Point

Alterations in kinematics and kinetics in the sagittal plane of the ACLR knee observed during running may predispose participants to joint-related issues, such as patellofemoral pain. Similarly, increased knee adduction moments in the affected limb may indicate unresolved biomechanical deficits. These findings suggest that the elite population may not be fully prepared to resume high-level activity within the 6-month time frame outlined in current rehabilitation protocols. A longer recovery period may be necessary to restore joint kinematics and kinetics to levels more consistent with a safe return to sport.
