Table 3 Number and frequency the demographically calculated and digitally templated sizes differed from the sizes implanted. Calc FemAP represents the demographically calculated size from the femur in the anterior-posterior dimension, while Calc TibAP represents that for the tibia. Calc FemML represents the demographically calculated size from the tibia in the medial-lateral dimension, while Calc TibML represents that for the tibia

From: Demographic data is more predictive of component size than digital radiographic templating in total knee arthroplasty
