Radiographic parameters including hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured at baseline, 6 weeks, and final follow-up. Patient-reported outcome measures were assessed using the Manchester-Oxford Foot Questionnaire (MOXFQ), visual analog scale (VAS) for pain, and EuroQol 5 dimension\u20135 level questionnaire. Recurrence was defined as a final HVA exceeding 20\u00b0. Complication rates and passive correctability were also analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Baseline characteristics were similar between groups, except for significantly higher initial IMA in the PECA group (17.8\u00b0 vs 15.8\u00b0,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009=\u2009.001). Both techniques achieved significant deformity correction.
