Treating and Preventing MCL Injuries

The medial collateral ligament (MCL) is one of the four ligaments that stabilize the knee. It is located on the inner side of the knee. It functions to prevent the knee from collapsing or buckling inward.

MCL Injuries

A ligament is a tissue that connects two bones together and provides structural support. A sprain is when a ligament is stretched or torn.

MCL sprains are very common, especially in sports that have a lot of quick side-to-side and rotational movements such as football, soccer, lacrosse, and skiing. The severity of injury can range from a mild stretch to complete tear of the ligament.

Causes and Risk Factors of MCL Injuries

MCL injuries are typically caused by either a twisting motion on a bent knee, or contact with the outside of the knee, that causes the knee to collapse inward.

Many cases of this injury to the knee ligament are the consequence of a direct collision with another athlete while playing a sport. Contact sports and sports requiring a lot of pivoting, shifting, and quick directional changes have a greater risk for MCL injury.

Recognizing an MCL Sprain

Common symptoms include:

  • Hearing or feeling a pop or tearing sensation on the inner side of the knee
  • Pain, swelling, or bruising on the inner part of the knee
  • A sense of instability or that the knee is going to give out

A diagnosis is made by finding out how the knee was injured, examination of the knee and the ligaments by gently touching and moving the knee in several directions. Your doctor will often order an x-ray or MRI imaging.

Treating the Injury

Many people who injure their MCL find that nonsurgical methods provide effective treatment.

Doctors usually recommend the R.I.C.E. technique — rest, ice, compression and elevation — as an initial treatment. Doctors typically suggest patients also use non-steroidal anti-inflammatory drugs (NSAIDs) such as naproxen or ibuprofen. Hinged knee bracing is often recommended after the injury.

You may return to your sport once pain is controlled, motion is full, and when strength, balance, and power are all equal to the uninjured knee. Time needed for recovery varies with the severity of the ligament injury, but it is commonly about 4 weeks.

Preventing Injuries to the MCL

While not all MCL injuries are preventable, you can take proactive steps to reduce the risks of ligament stretches, sprains and tears.

Balance, strength and power exercises may decrease the risk of MCL sprains. Focus on the thigh and hip muscles. Bracing as a preventative approach is controversial.
