Chronic ankle instability following ankle sprains causes pain and functional problems such as recurrent giving way. Within the 3 ligaments of the lateral ligament complex, 80% of patients tear the anterior talofibular ligament (ATFL), whereas the other 20% of patients tear the ATFL and calcaneofibular ligament (CFL). Rarely, the posterior talofibular ligament is involved. An incidence of 10% to 30% of patients will fail conservative treatment and result in chronic ankle instability that may require surgical treatment. To date, numerous open surgical procedures for anatomic repair or reconstruction of ATFL and/or CFL provide good clinical results.
