In this study, we attempt to explore the differences between anatomical and non-anatomical tibial baseplates in terms of rotation and coverage. To achieve this, we divided 80 dry bones into groups, and examined them using anatomical and non-anatomical baseplates. The results of the study showed that anatomical baseplates provided better coverage and also yielded better results according to the rotational assessment. Surgeons make rotational mistakes by non-anatomic base plates, when trying to achieve best coverage. Anatomic base plates warrant better coverage according to non-anatomic base plates when both are placed at the same rotational axis. It is more possible to adjust size and rotation correctly with the anatomic tibial components.
