What is the likelihood of tearing the same ACL twice?

National Athletic Trainers' Association

According to a study performed by Russell et al. and published in the British Journal of Sports Medicine, if an individual undergoes a proper rehabilitation protocol and consistently implements the use of a stabilizing brace, he or she has approximately a 6% chance of reinjuring the same anterior cruciate ligament (ACL), as well as a 6% chance of injuring the opposite ACL. Not adhering to a proper rehabilitation protocol carried out by a certified athletic trainer or physical therapist will increase the risk significantly.

Muscle & Connective Tissue Injuries

Muscle and connective tissue injuries include sprains and strains, which are the most common injuries for people engaged in physical sports. A sprain is an injury of a ligament, which connects our bones to each other. A strain is an injury that can occur to a muscle or a tendon, which connects our bones to our muscles. If you have a muscle or connective tissue injury, you will likely experience pain, swelling, and limited movement of that body part. Sometimes these injuries are evident as soon as they occur, while others take time to develop. Usually rest helps to heal the area, and ice can reduce swelling. If these remedies dont help you, physical therapy or surgery may be necessary for a full recovery.
