Knee Joint Ligaments

A ligament is a tough band of elastic connective tissue that helps support a joint and limit movement that is unwanted. There are four major ligaments in the knee that connect the femur and the tibia:
• The Medial Collateral Ligament (MCL) gives stability to the inner part of the knee.

• The last major ligament in the knee is the Posterior Cruciate Ligament (PCL) located in the center of the knee that controls backward movement of the tibia.

Knee Ligaments are crucial to the stability and support of the knee due to the anatomy of it not having any boney protection. Because the knee relies heavily on the support of these ligaments they are easily injured whether it be from contact or a quick force of muscle contraction like a change in direction.
