From: Single cut distal femoral osteotomy for correction of femoral torsion and valgus malformity in patellofemoral malalignment - proof of application of new trigonometrical calculations and 3D-printed cutting guides

Fig. 3

Elementary mathematical approach: a Increased antetorsion, decreased mLDFA; b If cutting plane is perpendicular, derotation leads to normal antetorsion and slight increased mLDFA; c If the cutting plane is oblique from a sagittal view, derotation leads to normal antetorsion and significant increased mLDFA
