What is Medial Collateral Ligament (MCL) Injury?

The medial collateral ligament (MCL) is located on the medial (inner) side of your knee and it connects the top of your tibia (shinbone) to the bottom of your femur (thighbone). It is one of the four major ligaments in your knee that provide stability to your knee joint. Its main function is to resist the movement of tibia or foot outwards in relation to the knee, also known as knee valgus. When this ligament is injured, it is often called an MCL sprain and it could either be an overstretched or torn MCL.

Causes of MCL Knee Injury

The MCL is very susceptible to damage when a great force is applied directly on the outer side of the knee, which stretches or tears the MCL. This can occur when making a sharp change in direction, twisting the knee whilst the foot is fixed, landing wrong from a jump or the most common, a blunt force hit to the knee, such as in rugby tackle. In most cases, incidents needs to happen at high speed to injure the MCL.

MCL Knee Injury Severity and Symptoms

The symptoms and severity of the MCL injury depends on the degree of stretching or tearing of the MCL. It can be graded in 3 levels: Grade 1 (Mild), Grade 2(Moderate) and Grade 3 (Severe).

  • Grade 1 MCL injury – The least severe MCL injury. Usually indicate slight stretch of the MCL but there is no actual tear. You may not feel too much pain or swelling in your knee joint but this can increase the risk of a repeat injury.
  • Grade 2 MCL injury – A moderate type of MCL injury where your ligament has been partially torn. This might cause instability in your knee joint and some common symptoms such as knee swelling, bruising and pain while moving the knee.
  • Grade 3 MCL Injury – The most severe type of MCL injury where the ligament tears completely, resulting in swelling or bleeding under the skin. This will also cause the knee joint to be unstable and you might find it hard to bear any weight. Usually, you might experience some severe pain that subsides quickly or no pain at all as all the pain nerve fibres are torn together with the ligament.

How is an Medial Collateral Knee Injury Diagnosed?

On an examination with a physical therapist such as a chiropractor, they will look for signs of ligament injury. The chiropractor might perform some stress test to determine the severity of the injury. A MRI may also be used to diagnose the knee injury and check the surrounding structures for combination injuries.

Treatments for MCL Injury

Dr Linda Schiller examines kneeThere are numerous treatment options for MCL injury and the type of treatment also depends on the severity of the injury. However, Grade 1 MCL injury might heal on their own after a few weeks or rest.

Immediate Treatment

Immediate treatment’s main goal is to ease the pain and help stabilising your knee. Immediate treatment options include:

  • Applying ice to reduce swelling
  • Elevating your knee above your heart to help with swelling
  • Taking nonsteroidal anti-inflammatory drugs (NSAIDs) to ease pain and swelling
  • Compressing your knee using an elastic bandage or brace
  • Resting

  • Physical therapy such as chiropractic to strengthen muscles and improve your knee’s range of motion
  • Low level laser therapy can speed up healing
  • Interferential therapy to increase blood flow and reduce inflammation
  • wearing a protective knee brace during physical activity
  • limiting activities that can cause further injury, such as contact sports

Surgery

In rare cases, an injury to MCL will require surgery. Surgery is needed when the ligament is torn in such way that it can’t repair itself. If the tear is in the middle of the ligament, your surgeon will stitch the ligament together. However, if your ligament is torn where it attaches to either your shinbone of your thighbone, your surgeon will often reattach your MCL using the following methods:

  • Large stitches
  • Bone staples
  • A metal screw
  • A device called suture anchor

Overall, the recommended management for MCL injury is to first applying some immediate treatment to ease the pain or reduce instability in the joint, then, consult a physical therapist like a chiropractor where you will be given exercise and stretching programmes to help strengthening your knee joint.
