Osteochondritis are lesions that can cause pain and stiffness of the ankle joint. It is caused by a twisting-type injury to the ankle, and unfortunately it can affect any age group. Symptoms include swelling and ankle pain.

In most and mild cases, restricting foot and ankle movement will resolve the problem. In more serious cases, surgery may be recommended. During the surgery, loose fragments of cartilage and bone are removed from the ankle joint and, in some cases, small drill holes are made in the defect to stimulate new blood vessels and to help form scar tissue that will fill the defect.
