The knee comprises of four major ligaments that connect the thigh bone (femur) to shin bone (tibia).
- Anterior Cruciate Ligament (ACL): Located in the center of the knee and controls the rotation and forward movement of the shin bone
- Posterior Cruciate Ligament (PCL): Located in the center of the knee and controls backward movement of the shin bone
- Medial Collateral Ligament (MCL): Gives stability to the inner part of the knee
- Lateral Collateral Ligament (LCL): Gives stability to the outer part of the knee
