Fig. 1From: Robot-assisted total knee arthroplasty improves mechanical alignment and accuracy of component positioning compared to the conventional techniquea The mechanical axis of the leg is the angle formed between the mechanical axis of the femur and tibia. b Radiologic measurement of femoral and tibial implants. α: coronal inclination of the femoral component with the mechanical axis of the femur, β: coronal inclination of the tibial component with the mechanical axis of the tibia, δ: sagittal inclination of the tibial component with the mechanical axis of the tibiaBack to article page
