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.
