Abstract

See full text

A revision knee system has a unique polymeric tibial bearing monobloc defining both a superior condylar articular bearing surface and an inferior tibial bearing face. The inferior tibial bearing face bears directly on tibial cut surface so as to withstand compressive loading force applied to the superior condylar articular bearing surface thereof. The bearing component comprises a polymeric keel extending from the inferior bearing face which engages a higher strength metallic stem inferiorly with respect to the inferior bearing face and which may be configured to engage the stem in a structurally resilient manner despite the lower material strength of polymer as compared to metal.
