After an ACL injury it is very important to start exercising as soon as possible. This is helps retain your muscle strength around the ACL, range of motion and control swelling. These functions are vital to prepare an injured athlete for ACL surgery. These exercises can begin immediately after an ACL injury.

After prehabilitation, the knee will feel and look normal. However, IT IS NOT! DO NOT run, cut, jump, land, return to ANY sports that will involve any changing of direction. If one does, the knee will go out and will likely sustain further serious injury.

Reduce Swelling

Ice (as much as possible)

(15-20 minutes, 2-3 times per day) acutely 20 minute Icing every 2 hours for first 48 hours after injury

Cover the knee with light clothing to protect the skin. Then place ice bags on top and over sides of knees. It is often helpful to use an ace bandage to keep the ice in place around the knee (It also allows one to walk around)


ICE is a great way to help with circulation and keep the swelling out of the knee.
