An orthopedic guide for preparing a particular patients bone to receive a prosthesis using a milling tool with a rotating burr comprises a platform having a top surface and a bottom surface adapted to face the patients bone. The platform defines an elongate milling track that extends through the platform from the top surface to the bottom surface of the platform, the milling track being sized and shaped so as to be adapted to guide the milling tool across the patients bone with the burr of the milling tool rotating beneath the bottom surface of the platform to be adapted to remove a first bone portion from the patients bone. A plurality of legs are coupled to the platform and each comprise a referencing end that is contour-matching fabricated as a function of the patients bone data to be adapted to abut the patients bone, the referencing ends of the plurality of legs adapted to cooperate to locate the orthopedic guide at a single predetermined location of the patients bone.
