The study will investigate alterations in post-surgical gait patterns among patients who have undergone all arthroscopic repair surgery for the anterior talofibular ligament (ATFL) due to ankle instability. The gait biomechanics of patients scheduled for surgery will be assessed preoperatively using pedobarographic analysis. Subsequent changes in walking biomechanics will be evaluated and interpreted at the 3rd and 6th postoperative months. Consequently, the impact of the all arthroscopic anatomical ATFL repair method on walking will be documented.
