a Tibial component slope is determined by the angle between the line perpendicular to posterior tibial cortex and the tibial component sagittal axis; b Femoral component sagittal alignment is determined by the angle between the line perpendicular to the component part placed on distal femur cut and the posterior cortical line of femur; c Interprosthetic divergence is the angle between the line perpendicular to the tibial component coronal axis and the long axis of femoral component
