Agility training following anterior cruciate ligament reconstruction.

The treatment program after anterior cruciate ligament (ACL) injury or reconstruction at the United States Military Academy embraces the four cornerstones of rehabilitation--strength, aerobic fitness, coordination, and confidence. It is divided into six phases--presurgery, to prepare the patient for postoperative rehabilitation; postoperative (or postinjury), to allow healing and to prevent thrombosis and muscle atrophy; early healing, to maintain muscle tone and joint motion in a protective device; late healing (water stage), to begin proprioceptive and agility training while regaining joint motion; healed (land stage), to gain greater agility and confidence in controlled situations; competition, to demonstrate if the rehabilitation program has been successful. This paper concentrates on the criteria for advancing from the water phase to the land phase and then to competition. The patient reverts to the preceding phase if pain or swelling is apparent. Full participation in competition is not permitted unless the patient masters all phases and can compete in athletics without fear of reinjury.
