Clinical outcomes were assessed using the visual analog scale (VAS) for pain, Karlsson-Peterson score, Tegner score, and Foot and Ankle Outcome Score (FAOS). A structured questionnaire evaluated the outcomes of sports participation, ankle recurrent sprains, subjective satisfaction, and surgical complications. Univariate and multivariate logistic regression analyses were conducted to identify factors influencing return to preinjury sports levels at final follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      There were 107 patients (111 ankles; 84.9% follow-up rate) included for analysis, with a mean age at the time of surgery of 15.2 \u00b1 2.0 years and a follow-up period of 5 to 10 years (mean, 86.4 \u00b1 17.7 months). Postoperative clinical scores showed significant improvements compared with preoperative scores, with VAS pain scores decreasing from 4.0 \u00b1 2.1 to 0.8 \u00b1 1.1, the Karlsson-Peterson score increasing from 55.8 \u00b1 20.8 to 91.4 \u00b1 7.9, the Tegner score increasing from 3.6 \u00b1 2.0 to 5.5 \u00b1 1.5, and the total FAOS score increasing from 64.4 \u00b1 18.7 to 93.0 \u00b1 6.2 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001 for all). All cases returned to daily activities and recreational sports levels at a mean time of 5.1 \u00b1 3.6 months after surgery. Among them, 55.0% were able to participate at their preinjury level of sports at final follow-up, while the other 45.0% were not, citing reasons such as ankle-related events (46.0%), health problems (10.0%), life-related events (18.0%), and personal preferences (24.0%).
