A multi-ligament knee injury (MLKI) is one of the most severe and complex injuries the knee can sustain. It is defined as a tear of two or more of the four major ligaments that stabilize the knee joint: the Anterior Cruciate Ligament (ACL), Posterior Cruciate Ligament (PCL), Medial Collateral Ligament (MCL), and Lateral Collateral Ligament (LCL). https://shashikanthorthohospital.com/multi-ligament-injuries/
