Figure 2. Standing anterior-posterior radiograph with a varus malalignment. Mechanical axis as hip-knee-ankle (HKA) and component alignment angles are represented. The HKA angle is the angle formed between the mechanical femoral and tibial axes. The femoral component (FC) angle is the angle medially between the distal surfaces of the femoral component and the femoral mechanical axis. The tibial component (TC) angle is the medial angle between the tibial component plateau and the tibial mechanical axis.
