Two types of experience were assessed: (1) general surgical experience, defined as self-reported years in practice as an orthopaedic trauma surgeon, and (2) prior use of patient-specific guides (PSGs). Secondary aim was to evaluate whether accuracy varies by anatomical location.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>24 orthopaedic-trauma surgeons performed 75 corrective osteotomies on cadaveric long-bones (43 single-cut, 32 double-cut; 107 cuts in total). Each osteotomy was preoperatively planned on CT-derived 3D-reconstructions, and PSGs were manufactured to guide the cuts. Postoperative CT-scans were used to compare planned and executed osteotomy planes. Surgeons completed a questionnaire reporting years of practice and annual PSG usage. A Spearman\u2019s rank-order correlation was used to test differences in accuracy versus experience, a Kruskal-Wallis test was performed to explore differences across anatomical locations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      General surgical experience ranged from 0 to 25 years (median 9), and PSG-usage from 0 to 20 cases annually (median 2). No association was found between general surgical experience and osteotomy accuracy (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.406 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.548). In contrast, PSG-experience correlated with improved accuracy for angular and translational deviation of the osteotomy plane (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.027 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.029).
