The primary outcome was the Foot and Ankle Outcome Score at the final follow-up. The visual analog scale for pain, American Orthopedic Foot &amp; Ankle Society score, and Karlsson ankle function score were measured as subjective outcomes. Posturographic analysis, as an objective outcome, was performed with a Tetrax device. Radiologic outcome evaluations were performed preoperatively and 2 years postoperatively using stress radiographs and magnetic resonance imaging in axial view. Complications, including retears, neuralgia, and knot irritations, were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      No significant differences were found between groups in clinical, proprioceptive, or radiologic outcomes at the final follow-up. Three retears (5.1%) were identified on postoperative MRI (group W, 3.4% [1\/29]; group WO, 6.7% [2\/30];\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .580).
