Characteristics and Outcomes of Surgical Treatment for Anterolateral Ankle Impingement Due to the Distal Fascicle of the Anterior Inferior Tibiofibular Ligament

ALAI due to DF-AITFL should be considered a possible cause of anterolateral ankle pain after an ankle sprain. The diagnosis can be reliably made with a thorough clinical examination and imaging studies. Half of the patients in this series also had lateral ankle instability. Surgical resection of the DF-AITFL and ligament reconstruction, if necessary, resulted in significant symptom improvement.
