This study aimed to compare the AFTL\u2013PTFL angle before versus after ankle lateral stabilization surgery, and to evaluate whether the ATFL\u2013PTFL angle correlates with the ligament injury severity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This retrospective study included 48 patients with mechanical ankle instability treated between 2016 and 2018. After arthroscopic evaluation, all patients underwent ankle lateral stabilization surgery comprising ligament repair (<jats:italic>n<\/jats:italic>\u2009=\u200928) or reconstruction (<jats:italic>n<\/jats:italic>\u2009=\u200920). The ATFL\u2013PTFL angle was measured in the axial plane on pre\u2010 and postoperative MRI. Comparisons were made of the pre\u2010 versus postoperative ATFL\u2013PTFL angles, and the ATFL\u2013PTFL angle of the repair versus reconstruction groups. Receiver operating characteristic (ROC) curve analysis was used to assess the diagnostic performance of the ATFL\u2013PTFL angle in selecting the surgical technique.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The postoperative ATFL\u2013PTFL angle was significantly decreased compared with preoperatively. The ATFL\u2013PTFL angle was significantly smaller in the repair group than the reconstruction group preoperatively and postoperatively. The area under the ROC curve was 0.741 (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01). The optimal cutoff point for the selection of ligament reconstruction was an ATFL\u2013PTFL angle of 89.4\u00b0 (sensitivity 0.85, specificity 0.61).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The ATFL\u2013PTFL angle decreases after ankle lateral stabilization surgery.
