What are the MCL and LCL Ligaments?
The Medial Collateral Ligament (MCL) and the Lateral Collateral Ligament (PCL) are ligaments in the knee that work jointly to provide support and stability to the knee. The MCL and LCL ligaments are two of the four major ligaments in your knee. The other two ligaments are the ACL and PCL Ligaments (Anterior Cruciate Ligament & Posterior Cruciate Ligaments).
