An optimized press-fit between a resected bone and an articular implant may, for instance, reduce undesirable qualities, including excess micromotion, stress transmission, and/or strain. By taking into account heterogeneous bone properties, the parameters of a bone resection can be determined as to optimize the press-fit between a resected bone and an articular implant. An optimized press-fit is obtained by determining ideal engagement characteristics corresponding to the fit between the fixation features of an articular implant and a bone. Then, taking into account a bone's heterogeneous properties, the parameters of a bone resection that would substantially achieve the determined ideal engagement characteristics are determined.
