Critical analysis of compensatory movement strategies following acl reconstruction

This study identified compensation strategies in ACLR athletes that persisted across 3 unilateral landing tasks. The injured limbs showed lower internal knee extension moments and increased hamstring activations. These compensations are typically seen as protective as they unload the knee joint and reduce anterior tibial translation. However, marker based Principal Component Analysis (PCA) also revealed increased whole body lateral lean. This has been associated with increased knee injury risk, suggesting that rehabilitation should not only focus on the knee but also address compensatory whole-body postural strategy disruptions.
