Various surgical approaches have been used including the central Achilles tendon splitting approach. This study aimed to report the 2-year clinical and radiologic outcomes after surgical treatment of IAT with a central tendon-splitting approach.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Seventy-five cases of IAT treated surgically via the open central tendon-splitting approach were analyzed. Clinical outcomes\u2009included the American Orthopaedic Foot &amp; Ankle Society (AOFAS) hindfoot score, visual analog scale (VAS), 36-Item Short Form Health Survey (SF-36) physical (PCS) and mental (MCS) component summary scores, all measured at baseline and 6 and 24\u2009months postoperatively. Radiologic parameters measured included the Fowler-Philip angle (FPA) and parallel pitch lines (PPL).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Three patients had clinically significant wound issues but healed completely by 3\u2009weeks. Mean AOFAS score improved from 45.63 preoperatively to 94.71 at 24\u2009months. Mean VAS score improved from 6.73 preoperatively to 0.55, mean SF-36 PCS from 35.98 to 48.74, and mean SF-36 MCS from 53.04 to 55.43 at 24\u2009months. Satisfaction at 2\u2009years was 94.3%. Mean FPA decreased from 62.0 degrees preoperatively to 34.0 degrees postoperatively. PPL was positive in 82.7% (62 of 75) of cases preoperatively, decreasing to 1.3% (1 of 75) postoperatively. Increasing age and higher preoperative VAS and SF-36 MCS scores were significantly associated with improvements in postoperative AOFAS, SF-36 PCS, and MCS scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Surgical treatment of IAT via the central tendon-splitting approach achieved substantial improvements in all patient-reported outcome measures measured.
