The medial collateral ligament (MCL) is a ligament located on the inner aspect of the knee that helps stabilize the knee joint. An MCL injury occurs when this ligament is stretched or torn during fall or sports activities

Treatment for an MCL injury typically depends on the severity of the injury, but may include the following:

1. I.C.E.: Rest, Ice, Compression, and Elevation can help reduce pain and swelling.
2. Physical therapy and rehabilitation: Exercises to improve strength, flexibility, and stability in the knee can aid in the recovery process.
3. Bracing: A knee brace can help provide support and stability to the injured knee.
4. Medications: Pain medications and anti-inflammatory drugs can be used to manage pain and swelling.

In severe cases, surgery may be necessary to repair a torn MCL. It is important to consult a healthcare provider to determine the best course of treatment for an MCL injury.
