The ACL is extremely important for the stability of the knee joint. It is often sprained or torn in a knee hyperextension injury, and often also involves a tear of the meniscus as well. Not only can we, at Goodell Physical Therapy, help diagnose and rehabilitate an ACL tear pre and post-surgery, but we can also help patients prevent ACL tears through education in proper movement patterns and stability exercises in both the athlete and the general population.
