The Medial Collateral Ligament also known as the MCL is the ligament within the knee joint that connect the thigh bone to the lower leg bone on the inside of the knee. It is one of the four major knee ligaments and its role is to resist valgus forces (forces pushing the knee inward). The other 3 major ligaments are the ACL, PCL, and ACL. Injury to the MCL is not the most common in the knee but can be very painful and limit future movement.

For this reason some athlete is high risk sports wear a MCL knee brace for prevention of injury. If an athlete does suffer from a MCL injury then wearing a MCL brace afterwards is highly recommended.

MCL Braces

There are two reasons to purchase a brace when considering your MCL: to protect it from injury or to help rehab it while returning to sport. MCL braces are not treated surgically so the best brace to use after an injury has occurred is a hinged knee brace. If the injury to the MCL is minor and you are looking for a brace that provides a lower level of support and is less expensive then you should be looking at the knee sleeves and braces with straps.


A hinged knee brace contains hinges designed to limit range of motion and prevent your knee from moving into a position that could injure the ligaments like hyperextension and bad alignment. These types of braces move with your body so they won’t limit your performance.

How does a MCL brace help?

Braces are built to do the work that an injured or weak ligament may not be able to do. A MCL brace will try and limit the amount of strain and force being placed on the MCL ligament. Some braces also contain a leverage system that takes stress off of the ligament. By taking the stress off a ligament and guiding the knee joint through a natural range of motion and limit movement that can be harmful.

Common Causes of a MCL Injury

MCL injuries are very common in contact sports and downhill skiing. Any sort of hit from the outside that forces the knee to move inward can damage the MCL. Activities that involve quick change of direction, twisting and bending can put the MCL at risk. Sports with a ton of stop and go movements, jumping and weaving are also dangerous. Common Sports for MCL Injury are:

  • Skiing
  • Football
  • Soccer

Symptoms of a MCL Injury

Immediately upon injury an athlete will feel a lot of pain on the inside of the knee that will be present with or without weight bearing. After that the knee will begin the swell mostly on the inside of the knee as well. The affected area will be tender to touch and range of motion can be limited.


There are three grades of MCL ligament injury. Grade 1 is classified by a small or minor tear of the ligament. In this case the ligament has been stretched but is still able to do its function within the knee, mild pain and swelling would be present. A grade 2 sprain occurs when the stretch and partial tearing of the ligament leads to the MCL ligament becoming loose. This will make the area painful to touch and more swelling will be present. A grade 3 sprain is referred to as a complete tear of the ligament. The MCL is no longer doing its job of holding the thigh bone and lower leg bone together. With a grade 3 sprain it is very painful, tender to touch, and painful to walk.
