Abstract
Purpose: To determine whether the use of suture tape augmentation (ST) would lead to improved clinical outcomes, increased stability, shorter postoperative immobilization, and earlier return to activity and sports compared with Broström repair (BR) in surgical treatment of chronic lateral ankle instability (CLAI). Methods: A systematic literature search was performed using Pubmed and Embase according to PRISMA guidelines. The following search terms were used: ankle instability, suture tape, fiber tape, and internal brace. Full‐text articles in English that directly compared BR and ST cohorts were included, with a minimum cohort size of 40 patients. Exclusion criteria were former systematic reviews, biomechanical studies, and case reports. Results: Ultimately, 7 clinical trials were included in this systematic review. Regarding the clinical and radiologic outcomes and complication rates, no major differences were detected between groups. Recurrence of instability and revision surgeries tended to occur more often after BR, whereas irritation of the peroneal nerve and tendons seemed to occur more frequently after ST. Postoperative rehabilitation protocols were either the same for both groups or more aggressive in the ST groups. When both techniques were performed with arthroscopic assistance, return to sports was significantly faster in the ST groups. Conclusions: In conclusion, suture tape augmentation showed excellent results and is a safe technique comparable to traditional Broström repair. No major differences regarding clinical and radiologic outcomes or complications were found. Level of Evidence: III, systematic review of level I, II, and III studies.
