Calculation of the estimated AP axis of the tibia and APP transverse axis (f). We calculated the estimated angle between the AP axis of the tibia (d) and the perpendicular line to APP (g) from KRA (#) and APP-CEA (□) with the formula; (AP axis of the tibia relative to APP transverse axis ) = (APP-CEA □) minus (KRA #). The solid lines represent the contour of the projected femoral condyle onto the femoral horizontal plane. The dotted lines represent the contour of the projected tibial condyle onto the femoral horizontal plane. AP: anteroposterior, APP: anterior pelvic plane, CEA: clinical epicondylar axis (c), KRA: knee rotation angle
