The medial collateral ligament is a band of tissue on the inside of the knee. It connects the thigh bone to the bone of the lower leg. It keeps the knee from bending inward. You can sprain or tear the ligament during activity that involves bending, twisting, or a quick change of direction. The ligament is often injured in football or soccer when the outside of the knee is hit.
You can treat minor injuries with home care. Your doctor may suggest you wear a brace that helps support your knee. A severe tear may need surgery.

Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems.
