The mean patient age was 44.6 \u00b1 9.2 years at the time of osteotomy, which was planned with mediCAD II software (Hectec, Niederviehbach, Germany). The Hospital for Special Surgery score, Lysholm\u2010Gillquist score, Tegner activity level, and International Knee Documentation Committee subjective score were used for clinical assessment. We evaluated radiographs obtained preoperatively and at 2, 6, and 12 months postoperatively using full\u2013weight\u2010bearing anteroposterior whole\u2010leg views and anteroposterior and lateral views of the knee. For statistical analyses, JMP 8.0.1 (SAS, Cary, NC) was used.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We observed an overall complication rate of 34% and a plate\u2010related complication rate of 23%. Plate\u2010related complications included loss of correction, fracture of the tibial plateau, screw failure, malunion, and fracture of the lateral cortical bone. A significant difference in the mechanical tibiofemoral angle of \u22121.3\u00b0 \u00b1 1.4\u00b0 (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001) was found between the follow\u2010up at 2 and 6 months.
