Absence of ATFL remnant does not affect the clinical outcomes of the modified broström operation for chronic ankle instability

Purpose The modified Brostrom operation for chronic ankle instability has demonstrated good clinical results. Absence of ligamentous tissue is a risk factor for recurrence of ankle instability after surgery. This study evaluated the effect of quality of ligament tissue (anterior talofibular ligament, ATFL) on prognosis, in a cohort of patients with chronic ankle instability after the modified Brostrom operation.
