Abstract

A prosthetic mold for forming a prosthesis is disclosed. The prosthesis can include a bone mating surface, an articulating surface, and an intermedullary post. The prosthetic mold can include a first portion, a second portion engageable with the first portion, and an injection portion. The first portion can be configured to form the articulating surface. The second portion can be configured to form the bone mating surface and define an intermedullary post cavity. Engagement between the first and second portions can define a mold cavity. The injection port can be axially aligned, and in communication, with the intermedullary post cavity. The injection port can engage an injection assembly. In one embodiment, the prosthetic mold is configured to form a tibial prosthesis. In another embodiment, the prosthetic mold is configured to form a femoral prosthesis.
