Abstract:
A prosthetic ankle including a talar component and a tibial component. At least a portion of top surface of the talar component has a convex curvature, relative to a location above the top surface, in the anterior to posterior direction as viewed in a sagittal plane cross-section, and a concave curvature relative to a location above the top surface, in the medial to lateral direction. An axis of cone projected based on medial and lateral circles located in medial and lateral sagittal plane cross-sections which approximate the average radius of curvature of the top surface of the talar component as viewed in medial and lateral sagittal plane cross-sections, has a total offset angle from the lateral direction in the range of 0° to 45°. In another aspect, the present invention further comprises a bearing component adapted for location between the tibial component and the talar component.

Claim (Index 12):
The prosthetic ankle of  claim 1 , wherein the tibial component has a bottom surface configured to substantially match the top surface of the talar component such that the talar and tibial components can move relative to one another and frictionally engage one another on the top surface of talar component and the top surface of the tibial component defines one or more structures selected from the group consisting of protrusions and ridges.
