Abstract

An augment element for tibial applications in a knee prosthesis. The augment element comprises a metal body of a substantially truncated conical shape configured to be inserted into a bone extremity and having an outer surface comprising a metal trabecular surface The the metal body is hollow with an axial through-cavity defining a plurality of substantially annular transversal sections. The metal body is inclined in a direction of inclination, so as to define at least one eccentricity between a first transversal section at a first end of the axial through-cavity and a second transversal section at a second end of the axial through-cavity The first transversal section at the first end is larger in size than the second transversal section at the second end. The metal body comprises lateral walls having respective curved and concave shapes with respect to the outside of the metal body, to replicate a medial/side and rear bone anatomy.
