Zusammenfassung:	A prosthesis may have an articulating component formed via casting and a 3D printed bone anchoring component with a joint-facing side and a bone-facing side. The bone-facing side may have a bone engagement surface with a porous structure with pores selected to facilitate in-growth of the bone into the pores. The bone facing side may further have a surface layer of Titanium Dioxide nanotubes. The joint-facing side may be secured to the articulating component by melting Titanium nanoparticles at a temperature below the melting temperatures of the major constituents of the articulating component and/or the bone anchoring component, such as Cobalt, Chromium, and/or Titanium, so as to avoid significantly modifying the crystalline structures of the articulating component and/or the bone anchoring component. The melting temperature of the Titanium nanoparticles may be about 500° C.
