Influence of Anterior Talofibular Ligament Injury and Ankle Anterior Displacement on Symptoms in Individuals With Chronic Ankle Instability.

Context: Repeated ankle sprains can lead to injuries, including those of the anterior talofibular ligament (ATFL); however, the extent to which these ligament injuries are associated with symptoms of chronic ankle instability (CAI) remains unclear.

Objective: To examine the influence of ATFL injury and ankle anterior displacement on symptoms of CAI.

Design: Case-control study.
