Background and Objectives: This study aimed to evaluate the effects of subtalar joint axis-based balance exercises on the anterior talofibular ligament (ATFL) thickness, ankle strength, and ankle stability after an arthroscopic modified Broström operation (AMBO) for chronic ankle instability (CAI).
Materials and Methods: The study included 47 patients diagnosed with CAI who underwent AMBO and were randomly divided into three groups: control (
n = 11), general balance exercise (
n = 17), and subtalar joint axis balance exercise (
n = 19), regardless of the affected area. Participants in the exercise rehabilitation group performed exercises for 60 min twice a week for six weeks, starting six weeks after AMBO. ATFL thickness, ankle strength, and ankle dynamic stability were measured using musculoskeletal ultrasonography, Biodex, and Y-balance test, respectively, before and after treatment.
Results: Compared with the remaining groups, the subtalar joint axis balance exercise group had reduced ATFL thickness (
p = 0.000), improved ankle strength for eversion (
p = 0.000) and inversion (
p = 0.000), and enhanced ankle stability (
p = 0.000).
Conclusions: The study results suggest that subtalar joint axis-based balance exercises may contribute to the early recovery of the ankle joint after AMBO.
