Ligament Injuries

By Justin Delicato, PTA

Ligament Injuries

A ligament is an elastic tissue around a joint that connects bone to bone and provides the bone with stability and support. Ligaments are strong, but they can be stretched or even torn. Ligaments are located in your shoulder, elbow, knee, and ankle, as well as other parts of the body. When a ligament tear happens, it causes instability within the joint, and the ligament is torn. The most common ligament injuries occur in the knee, ankle, and elbow. Sporting activities typically cause these injuries. Below we will discuss the most common ligament injury for the knee, ankle, and elbow.

What are the 4 Major Knee Ligaments?

Anatomy of the knee

  • ACL (anterior cruciate ligament)- controls forward movement and rotational movement of shinbone
  • PCL (posterior cruciate ligament)- control backward movement
  • MCL (medial cruciate ligament)- provides the inside of your knee with stability
  • LCL (lateral cruciate ligament)- provides the outside of your knee with stability

The most common knee ligament injury is of the ACL. ACL injuries occur when your feet plant in one direction and your knee is twisted in another. The most common sport in this injury occurs in football. If you would like to learn about ACL Reconstruction Surgery, this VIDEO may help.

What Are The Main Ankle Ligaments?

  • Anterior talofibular ligament- most common ligament injured in the ankle.
  • Posterior talofibular ligament- limits dorsiflexion
  • Calcaneofibular ligament- resists adduction.

The Anterior Talofibular ligament is the weakest and most commonly injured ligament in the ankle. This ligament absorbs most of the impact when the foot is planted unnaturally or when the ankle twists awkwardly.

A lateral ankle sprain is an injury to the ligaments in the outside of the ankle. It is a common ligament injury

Shoulder Ligament Injuries

When the ligaments holding the shoulder together tear, they can no longer hold the joint together. Also known as a dislocated shoulder. Falling on the shoulder or a violent twisting can cause the shoulder to dislocate. Athletes are especially susceptible to shoulder problems. Depending on the severity of the injury, it may take two to three weeks to adequately heal. In severe cases, the shoulder may need surgery. To help with pain, you should apply ice right after your injury. You should limit the movement of the shoulder by keeping it in a sling.

 

Elbow Ligaments Injuries

Ligament injuries can occur from overuse

  • Ulnar collateral ligament (UCL)
  • Radial collateral ligament

The most common ligament injury in the elbow is the UCL or the ulnar collateral ligament. This ligament injury typically occurs in baseball players due to the overuse of the elbow. A commonly known surgery for the repair of this ligament is Tommy John Surgery. An injury such as falling on an outstretched arm could also cause damage to this ligament as well.
