Femurs were classified into three groups based on the degree of antecurvature using the distal diaphyseal angle (DDA). Virtual surgery was simulated at 7\u2009cm above the joint line using two osteotomy methods (shaft\u2010perpendicular and distal femur condylar line [DFC]\u2010parallel) and two derotation angles (10\u00b0 and 20\u00b0). Mechanical lateral distal femoral angle (mLDFA) was measured before and after simulation. Multivariable and stratified regression analyses were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Greater antecurvature led to larger mLDFA decrease, with more pronounced valgus shifts at higher derotation angles. Making DFC\u2010parallel osteotomy significantly reduced valgus change regardless of bowing (\n                      <jats:italic>\u03b2<\/jats:italic>\n                      \u2009=\u2009\u22120.331,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.005).

The combination of DFC\u2010parallel osteotomy with 10\u00b0 derotation provided the least valgus change (\n                      <jats:italic>R<\/jats:italic>\n                      \u00b2\u2009=\u20090.84).

Although the optimal target angle for derotation remains a surgical choice, understanding the relationship between sagittal bowing and coronal alignment can help tailor patient\u2010specific decisions. To minimise valgus shift after supracondylar FDO, aligning the osteotomy plane parallel to the distal femur condylar line can be effective. This method is simple and practical for standard surgical procedures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of
