What Is Medial Collateral Ligament?

Medial Collateral Ligament

Several tissues run along your legs. One of the thick band of tissue (about four to six inches) that runs down your inner knee is known as the medial collateral ligament. Also referred to as MCL, the wide tissue runs from the femur (your thighbone) to the tibia (shinbone). So, the MCL is located on the side of your knee (close to your other knee). It is one of the four most significant ligaments you can find in your knee joint. MCL is an important part of the leg that keeps your knee stable. It facilitates the easy rotation of the knee and prevents your leg to extend inwards too far.

What Is MCL Tear Or Injury?

The medial collateral ligament holds your bones along the joint together. It provides strength and stability to the joint. The MCL tear refers to the injury caused due to sprain. The injuries to the medial collateral ligament either tear it or stretch to the maximum. Therefore, the MCL tear can cause high-level of pain and discomfort. In most cases, you can suffer from it due to a direct blow to the knee. So, the injury is quite common in contact sports.

Main Causes Of MCL Tear

As discussed above, medial collateral ligament tear occurs in contact sports. It happens when your knee gets hit directly on the outer side. Your ligaments have restricted stretching ability to function properly. But, an MCL tear can stretch the ligaments present on the inside region of the knee too far. So, the result is pain and swelling. In many cases, it is observed that MCL tear accompanies with the anterior cruciate ligament tear (ACL).

Repeated stress is another cause associated with the medial collateral ligament tear. When your MCL suffers too much stress, it is more prone to injuries and sprains.

So, you may experience more pain and swelling compared to the grade 1 MCL injury. It requires several weeks of rest and physical therapy to regain mobility.

Grade 3
