  1. Continuous data are presented as mean (standard deviation)
  2. In the scanograph, the minus number means the angle of varus deviation and the positive number means the angle of valgus deviation
  3. MA mechanical alignment, AA anatomical alignement, FBA femoral bowing angle in the full-length weight-bearing radiograph, CFA femoral component angle, CTA coronal tibia-component angle, SFA sagittal femoral component angle, STA sagittal tibial component angle
