Abstract:
1. A tibial base component for a tibial implant comprising: a lateral compartment, a medial compartment spaced from the lateral compartment defining an open central section therebetween and a connecting portion connecting the medial and lateral compartments at an anterior end of the base component to be located adjacent an anterior tibia, wherein the open central section of the base component intermediate the spaced medial and lateral compartments is open to a posterior end of the base component, wherein the connecting portion and, the medial and lateral compartments have a bone contacting surface and a superiorly facing surface, the connecting portion having a convexly curved anteriorly facing surface, the convexly curved anteriorly facing surface curved convexly in an anterior direction along an arc lying in a sagittal plane bisecting the open central section of the tibial base component along a proximal to distal extent of the tibial component, and has a first inferiorly facing planar angled surface extending at a first angle from adjacent the anterior end of the base component at a bone contacting surface of the connecting portion proximally and posteriorly to a posterior end of the connecting element, the first planar angled surface defining an anterior end of the open central section at the sagittal plane bisecting the open central section of the tibial base component.
