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 Range of Motion

Leg Extensions

Prone Hangs (2)

(5-20 minutes, 1-2 times per day)

Lie face down on a bed or table. Scoot back to the edge of the table so that the edge of the table rests just above the knee caps. This will force the knee to reach full extension. Hold this position for 5 minutes or greater until the heights of the heals are equal.


It is optimal to have full range of motion prior to having your surgery.
