The Foot and Ankle Outcome Score (FAOS), American Orthopaedic Foot &amp; Ankle Society (AOFAS) ankle-hindfoot scale, visual analog scale (VAS) for pain, and 36-Item Short Form Health Survey (SF-36) were used to compare the functional outcomes between the preoperative and final follow-up assessments.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The mean FAOS significantly improved in regard to all subscores ( P &lt; .001).
