Orthopaedic tibial prosthesis having tibial augments

摘要

A tibial orthopaedic prosthesis assembly for use during performance of a knee replacement procedure includes one or more tibial augments configured to be coupled to a tibial tray. Each tibial augment includes an exterior side surface of varying angulation relative to a top surface of the tibial augment.

主权项

1. A tibial augment configured to be secured to an implantable prosthetic tibial tray, the tibial augment comprising:
a top proximal surface that abuts a bottom surface of the tibial tray when the tibial augment is secured to the tibial tray; a bottom distal surface opposite the top proximal surface; an exterior side surface that extends from the top proximal surface to the bottom distal surface, the exterior side surface including a side surface section extending from an anterior-most point of the exterior side surface to a posterior-most point of the exterior surface, wherein the side surface section defines (i) a first interior angle relative to the top proximal surface at the anterior-most point of the exterior side surface and (ii) a second interior angle relative to the top proximal surface at the posterior-most point of the exterior side surface that is different from the first interior angle; an interior side surface positioned opposite the exterior side surface, wherein the interior side surface defines a third interior angle with the top proximal surface that is a right angle; and a medial end surface extending from the top proximal surface to the bottom distal surface and from the exterior side surface to the interior side surface of the tibial augment at the anterior-most point of the exterior surface.
