Abstract Background The arthroscopic Broström–Gould procedure (ABG) gained particular attention among clinicians and researchers due to its high rate of satisfactory results. There is a lack of evidence regarding the differences in clinical outcomes for the various suture techniques. The purpose of this study was to compare the differences in clinical effect in patients treated with one-anchor modified Mason–Allen suture or two-anchor horizontal mattress suture for chronic ankle instability (CAI). Methods This retrospective cohort study examined CAI patients who underwent either one-anchor modified Mason–Allen suture or two-anchor horizontal mattress suture ABG between January 2018 and January 2020. Patients were divided into two groups based on the suture knot type used and the associated number of anchors. The operative time, surgical cost, Visual Analog Scale (VAS), American Orthopedic Foot & Ankle Society (AOFAS) Score, Karlsson Ankle Functional Score (KAFS), the rate of return to sports, complications, and measured biomechanical strength using standardized equipment were compared between groups. Results Sixty-four CAI patients were included (one-anchor modified Mason–Allen suture group n = 30, two-anchor horizontal mattress suture group n = 34). Compared to the two-anchor horizontal mattress suture group, the one-anchor modified Mason–Allen suture group had significantly shorter operative time (p .05) between the one-anchor modified Mason–Allen suture and two-anchor horizontal mattress suture at 2 years after surgery. Conclusion ABG using a one-anchor modified Mason–Allen suture showed comparable clinical results to a two-anchor horizontal mattress suture in the treatment of CAI at intermediate-term follow-up time. However, one-anchor modified Mason–Allen suture may be a faster, simpler, cost-effective substitute technology. Level of evidence Level III, comparative study.
