Patient-specific instruments (PSIs) have the potential to mitigate the technical drawbacks associated with SMO that are performed free-hand, but their accuracy has not been investigated. Therefore, we aimed to perform a pre- vs post-operative comparison to assess the accuracy of PSI in the setting of SMO correction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Eighteen patients (mean age\u2009=\u200947\u2009\u00b1\u200913.5\u2009years) who underwent SMO with a PSI were prospectively recruited in a pre-post comparative study design. Inclusion criteria were correction of supramalleolar ankle varus or valgus deformity by a closing wedge SMO. Exclusion criteria consisted of biplanar SMO that required associated free-hand osteotomies. Clinical outcomes were collected by the American Orthopaedic Foot &amp; Ankle Society (AOFAS), European Foot and Ankle Society (EFAS), and visual analogue scale (VAS) scores. Apart from the standard weightbearing radiographs, a weightbearing CT was performed to generate corresponding 3-dimensional (3D) bone models and measure the lateral distal tibia angle (LDTA) as main radiographic parameter.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The pre-operative radiographic parameters of the tibia joint alignment in patients with ankle varus (n\u2009=\u200912) deformity (LDTA\n                      <jats:sub>var<\/jats:sub>\n                      \u2009=\u200996.5\u00b0\u2009\u00b1\u20094.5\u00b0) and valgus (n\u2009=\u20096) deformity (LDTA\n                      <jats:sub>valg<\/jats:sub>\n                      \u2009=\u200982.4\u00b0\u2009\u00b1\u20092.5\u00b0) improved significantly relative to their post-operative equivalents (LDTA\n                      <jats:sub>var<\/jats:sub>\n                      \u2009=\u200990.2\u00b0\u2009\u00b1\u20093.2\u00b0); LDTA\n                      <jats:sub>valg<\/jats:sub>\n                      \u2009=\u200990.9\u00b0\u2009\u00b1\u20090.8\u00b0;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009&lt;\u2009.05).
