Fig. 1

a Long-leg radiograph demonstrating the mechanical axis relative to the anatomical axis of the lower extremity. b Mechanical alignment of the knee places components at 90° with the mechanical axis of each bone. c Anatomical alignment aims for a lateral distal femoral angle (LDFA) of 3° valgus to the femoral mechanical axis (also commonly described as 9° valgus to the femoral anatomical axis). The tibial components are placed with a medial proximal tibial (MPTA) of 3° varus. d Individualized alignment techniques.
