Arthrofibrosis (from Greek: arthro- joint, fibr- fibrous and -osis abnormality) is an inflammatory condition that leads to the production of an excessive scar tissue in or around major joints. Arthrofibrosis can be caused by the initial injury to the joint or from surgical complications. Infections and bleeding into the joint are believed to be major causes or contributing factors involved in the disease. Arthrofibrosis is one of the major complications of ACL surgery and is one of the most difficult to treat. Whatever the cause, the excess scar tissue limits range of motion (“ROM”) and functionality. The condition can be quite painful and debilitating. The treatment of Arthrofibrosis requires very specialized care and only a handful of orthopedic surgeons in the world have a significant amount of experience treating this condition.
