Design of the femoral prosthesis. A) Prosthesis parameters. B) CAD model of the femoral prosthesis. C) Template to trim the allogeneic bone to match the surfaces in the distal end of the femoral prosthesis. D) The trimmed allogeneic bone was set in the outer surface of the individualized metal prosthesis to form an individualized femoral prosthesis. E) Stepped contact in the junction zone. F) Allogeneic bone covering the junction at the distal end of the remaining femur and fixed with a band. G) Final 3D model of distal femur reconstruction.
