Ankle instability

Abstract

Ankle injuries are among the most commonly treated musculoskeletal injuries. In the United States, there are 23,000 ankle injuries each day, and the United Kingdom sees nearly 5,000.1,2 Within orthopedics, estimates place the incidence of ankle sprains between 10% and 25% of all musculoskeletal injuries.3,4 Of these, nearly 85% involve the lateral ankle complex.5 The sequelae of these injuries can be variable. Conservative management with functional rehabilitation can lead to good-to-excellent results in 70-85% of these injuries,6 but 20-40% will have persistent pain and instability.7,8
