Sex-Specific Differences Following Lateral Ankle Ligament Repair

Background: Chronic ankle instability is a common condition that can be treated with lateral ankle ligament repair. These procedures have a reported success rate greater than 85% in the literature, but little has been reported about the differences in postoperative outcomes between males and females...

Description
Summary:Background: Chronic ankle instability is a common condition that can be treated with lateral ankle ligament repair. These procedures have a reported success rate greater than 85% in the literature, but little has been reported about the differences in postoperative outcomes between males and females. The purpose of this study was to evaluate sex-specific outcomes following lateral ankle ligament repair. Methods: In this systematic review and meta-analysis, we used Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria to search for articles on electronic databases and included studies in which study participants underwent primary lateral ligament repair and sex-specific outcomes were evaluated. Functional postoperative outcomes for males and females were recorded and statistically analyzed. Results: Out of 2768 studies, 7 (0.25%) met inclusion criteria and were analyzed in this review. These studies included 618 patients (402 males [65%] and 216 females [35%]) who underwent primary lateral ligament repair for ankle instability. Karlsson score (P = .1582) and American Orthopaedic Foot & Ankle Society (AOFAS) score (P = .1586) analyses found no statistically significant difference between males and females. Postoperative success rate—defined as a “good” or “excellent” Karlsson score (>81)—was not found to be significantly different between males and females (P = .9374). Conclusion: There was no difference in postoperative mean Karlsson scores, AOFAS scores, or success rates between males and females who underwent primary lateral ankle ligament repair. Level of Evidence: Level IV, therapeutic.
