Preoperative MRI Signal Intensity of the Anterior Talofibular Ligament Is Not Associated With Mid- to Long-term Outcomes After Modified Broström Procedure in Adolescents With Chronic Lateral Ankle Instability: A Propensity-Matched Cohort Analysis

Preoperative ATFL signal-to-noise ratio (SNR) on MRI was not associated with mid- to long-term outcomes after modified Broström repair in adolescents with chronic lateral ankle instability. These estimates should be interpreted with caution given the relatively small sample, potential residual confounding, and SNR variability. Within this cohort, favorable long-term outcomes were achieved across the range of preoperative SNR values.
