An improvised anthroplastic prosthetic implant having, in some embodiments, secondary screws with threaded shafts for forming pilot holes into the resected cancellous bone surface, such as the tibia, and primary screws with tapered heads for replacing the secondary screws and forming a Morse friction fit with the implant and seating the implant in close apposition to, and at less than 150 um in, resected bone thereby facilitating implant stability, wherein the heads of the primary screws are recessed into a counterbore in the baseplate to improve axial postoperative stability of the implant.
