Abstract

A method for forming a prosthesis comprising a bone-like portion and a cartilage-like portion can comprise additively manufacturing a first positive mold in accordance with a portion of a first three-dimensional model of a portion of a bone. A first negative mold can be formed from the first positive mold. The bone-like portion can be created within the first negative mold. A second positive mold of the bone and a cartilage can be additively manufactured from a second three-dimensional model. A portion of the second three-dimensional model can correspond to a portion of the first three-dimensional model. A second negative mold can be formed from the second positive mold. The bone-like portion can be positioned in the second negative mold so that the second negative mold and the bone-like portion can define a cartilage space that can be filled with a material to form the cartilage-like portion of the prosthesis.
