What Is the Anatomy of Knee Ligaments?

There are four ligaments in the knee: the medial collateral, or MCL, the lateral collateral, or LCL, the posterior cruciate, or PCL, and the anterior cruciate, or ACL, explains Healthline. The collateral ligaments provide stability from side to side, and the cruciate ligaments provide front-to-back stability, as WebMD explains.

Ligaments connect a bone to another bone, and in the case of the knee, the bones involved include the femur, the tibia and the fibula. The MCL connects the tibia to the femur, the LCL connects the femur to the fibula, and the PCL and ACL connect the femur to the tibia, according to WebMD.
