Abstract

A method for optimizing the fixation of a monoblock tibial implant for press-fit into the dense cancellous bone of the proximial tibia, and to characterize initial stability for both the Medical-Lateral (ML) and Anterior-Posterior (AP) directions, was presented. The length and cross-section size of the two hexagonal pegs were based on the anatomy of the proximial tibia with pegs 16 mm long, 12.7 mm corner-to-corner, and 10.2mm flat-to-flat, in dimensions. It was observed that the monoblock design's flexibility and the location of its fixation pegs inline with the condylar bearing loads allowed better resist moments. It was found that the porous tantalum monoblock tibia had higher flexibility, similar AP stability and greater ML stability.
