The most common ankle sprain involves tearing of the main ligament, the anterior talofibular ligament, located at the front and outside of the ankle joint. Usually, the ankle twists inside and the patient develops pain and swelling at the ankle joint. If treated immediately with soft tissue massage, bracing, and careful range of motion exercises, most ankle sprains and tears go on to heal normally without developing ankle instability. If however, the torn ligament does not heal properly, the ankle can go on to develop instability and often the patient will complain of the ankle giving way or not feeling stable. The physical exam often reveals a talar shuck or instability of the ankle joint.
