ACL Tear 

The anterior cruciate ligament (ACL) helps hold the knee joint together and provides stability. A torn ACL is a sports injury that may occur when landing the wrong way, changing direction or stopping quickly, or from a direct blow to the knee. Pain, swelling, and loss of range of motion are symptoms of a torn ACL. It may be difficult to walk. A torn ACL needs to be reconstructed surgically, usually using a graft from another ligament in the patient’s own body. Significant rehabilitation is necessary to restore the strength and function of the knee joint after surgery. Depending on the age, health status, and desired activity level of the patient, some may not elect to have surgery. In that case, braces and physical therapy will not cure the condition but may provide some relief.
