what is a torn mcl

The medial collateral ligament (MCL) is a broad, thick band that runs down the inner part of the knee, from the femur (thighbone) to a point 1.5 to 2 inches from the top of the tibia (shinbone) . A torn MCL occurs when the ligament is stretched or torn due to a strong force hitting the outside of the knee. The tear can be partial or complete, and the severity of the injury is categorized based on the extent of the tear. Symptoms of a torn MCL include pain, stiffness, swelling, tenderness along the inside of the knee, and knee instability. A popping sensation in the knee may also be felt at the time of injury. Treatment for a torn MCL depends on the severity of the injury and can range from rest and physical therapy to surgery. Recovery time can vary from a few weeks to several months. People who play high-impact sports such as football or martial arts, or sports that involve lots of jumping, sprinting, and quickly changing directions are at a higher risk of a torn MCL.
