The mechanical superiority of suture tape augmentation associated with the Broström-Gould procedure for treating lateral ankle instability has been reported. This study aimed to describe functional results using the visual analog scale (VAS), American Orthopedic Foot & Ankle Society (AOFAS) scale, and Short Form of Quality of Life Survey (SF-36) in patients with ankle lateral instability who underwent the modified Broström-Gould repair and suture tape augmentation and to determine the recurrence of injury and the impact on the perception of its stability. This retrospective cohort study included patients with lateral ankle instability treated using the modified Broström-Gould procedure and suture tape augmentation from December 2015 to July 2018 with a 6- to 36-month follow-up. Clinical and functional results were evaluated using the 3 aforementioned scales. p ≤ 0.05 was considered statistically significant. Twenty-eight patients were included, 18 (64%) males and 10 (36%) females (mean ± standard deviation age of 33.25 ± 12.73). The mean pre- and postoperative VAS scores were 6 ± 1.18 and 0.53 ± 0.92, respectively. The average pre- and postoperative AOFAS scores were 65.89 ± 15.08 and 94.60 ± 6.88, respectively; results were excellent (91 to 100) in 18 (64%) patients and good (81 to 90) in 10 (36%). Three patients experienced recurrence of injury treated with physical therapy, and their progress was satisfactory; stability perception was maintained. Excellent clinical and functional results were demonstrated in our study using suture tape augmentation in the modified Broström-Gould procedure, which probably protects against the recurrence of lateral ankle instability.
