What is the first treatment for an MCL injury?

The medial collateral ligament runs along the inner side of the knee and helps resist sideways stress. A brace can limit movements that strain the healing ligament while still allowing suitable motion. The severity of the injury, knee stability, pain, swelling, and any other damaged structures determine how much support you need. A clinician may also recommend temporary activity modification and a staged exercise plan.

Wear the knee brace as directed and avoid twisting, cutting, contact sport, or uneven-ground activity until your clinician says they are appropriate. Keep the knee moving gently within comfort so it does not become stiff. Physiotherapy can progress from swelling and range-of-motion work to strength, balance, and controlled loading. A return-to-sport programme can then test the movements and confidence needed for your activity instead of relying on pain alone.

Arrange prompt assessment if you cannot bear weight, the knee gives way repeatedly, swelling appears quickly, or the leg becomes numb, cold, or unusually pale. Seek urgent help after a major impact or when pain is severe and the knee looks deformed. Persistent locking or pain despite protection also deserves review because another knee structure may be involved.

How much time should I use the brace each day? Which exercises can I start safely? What strength, balance, and movement tests should I pass before returning to sport?
