The most common mechanism is an inversion stress that injures, in order, the anterior talofibular, calcaneofibular, and posterior talofibular ligaments. The medial deltoid is the strongest ligament; therefore, isolated injuries are rare, and medial ankle sprains are often associated with lateral malleolar or syndesmotic injuries.
