A patient specific system for joint replacement surgery that includes a custom cutting guide having an inner surface shaped to match the anatomy of a surface of a patient's joint to be resected. The custom cutting guide is designed for use with a corresponding prosthesis. A slot and guide holes are formed in the custom cutting guide corresponding to features protruding outwardly from a positive physical bone model. The slot guides a tool during resection of the femur to produce a first resected surface on the femur for mounting the prosthesis. The guide is formed from the positive physical model by applying a polymeric composition to the outer surface of the positive physical model including the features corresponding to the slot and guide holes of the custom cutting guide. |
