Description
Anterior cruciate ligament (ACL) tear was proven to cause kinematical anomalies during the execution of in vivo activities, and this suggests that knee ligaments’ biomechanics could be affected by ACL injury. The aim of the present study was to investigate the elongation pattern of the collateral ligaments and the posterior cruciate ligament (PCL) before and after ACL reconstruction in the execution of a single-leg squat. The medial collateral ligament was shown to significantly stretch between 0° and 30° in ACL deficient knees during the descendant phase of the squat. No differences were identified for the LCL and the PCL.
