Abstract
The present disclosure discloses a tibial plateau prosthesis with trabeculae containing zirconium-niobium alloy on oxidation layer and a preparation method thereof. The preparation method uses zirconium niobium alloy powder as raw material, conducting a 3D printing for one-piece molding to obtain an intermediate product of the tibial plateau, performing hot isostatic pressing and cryogenic oxidation to obtain the tibial plateau prosthesis comprising a proximal trabecular layer and a distal trabecular layer; the pore size and porosity of the proximal trabecular layer are evenly arranged, and the distal trabecular layer are partitioned; the topological structure of the trabeculae of the tibial plateau prosthesis is gradiently distributed from three dimensions; the micro-strain in the 64%-72% region of the finite element model of the tibial plateau bone tissue is between the minimum effective strain threshold and the supraphysiological strain threshold, which increases the mechanical adaptation of the prosthesis.
