Ligaments are bands of tough, elastic connective tissue that surround a joint to give support and limit the joint’s movement.

When ligaments are damaged, the knee joint may become unstable. Ligament damage often happens from a sports injury. A torn ligament severely limits knee movement. This results in the inability to pivot, turn, or twist the leg. Surgery is a choice to repair a torn ligament if other medical treatment is not effective.

The knee has 4 major ligaments. The 4 knee ligaments connect the thigh bone (femur) to the shin bone (tibia). They are:

Anterior cruciate ligament (ACL). This ligament is in the center of the knee. It controls rotation and forward movement of the shin bone.
Posterior cruciate ligament (PCL). This ligament is in the back of the knee. It controls backward movement of the shin bone.
Medial collateral ligament (MCL). This ligament gives stability to the inner knee.
Lateral collateral ligament (LCL). This ligament gives stability to the outer knee.

Symptoms of Knee Ligament Injury

Cruciate ...
... injury
A cruciate ligament injury often causes pain. Often you may hear a popping sound when the injury happens. Then your buckles when you try to stand on it. The knee also swells. You also are not able to move your knee as you normally would. You may also pain along the joint and pain when walking. The symptoms of a cruciate ligament injury may seem like other health conditions. Always see your healthcare provider for a diagnosis.

Collateral ligament injury
An injury to the collateral ligament also causes the knee to pop and buckle. It also causes pain and swelling. Often you will have pain at the sides of the knee and swelling over the injury site. If it is an MCL injury, the pain is on the inside of the knee. An LCL injury may cause pain on the outside of the knee. The knee will also feel unstable, like it is going to give way.
