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.

Retain Muscle Size and Strength

Quad Sets with Straight Leg Lifts

(3 sets of 10 reps, 1-2 times per day)

Sit down on the floor or table. Pull your toes back towards the knee (stretching the calf). Push the back of the knee down so it touches the floor. Tighten the quad (thigh muscle) and make it as hard as possible. Then lift your heal off the floor keeping the leg straight. Hold it off the ground approximately 6 inches. Hold it for 10 seconds then return it to the floor.
