1. A method of associating a plurality of landmarks with a patient tissue, each landmark being associated with the patient tissue in a predetermined marking location and/or a predetermined marking trajectory, the patient tissue including a primary patient tissue area adapted to directly receive an implant and an anatomically differentiated bordering secondary patient tissue area, the method comprising:
obtaining a landmark guide having a base at least partially customized responsive to preoperative imaging of the patient tissue, the base having an upper base surface and a lower base surface opposite the upper base surface, the lower base surface contoured to mate with the primary patient tissue area, the portion of the lower base surface and the primary patient tissue area matching to achieve a preselected relative orientation;
mating the base of the landmark guide with the primary patient tissue area in a preselected relative orientation;
fixing a first landmark to the primary patient tissue area in the predetermined marking location and/or the predetermined marking trajectory while the base of the landmark guide is mated to the primary patient tissue area;
fixing a guidewire pin to the secondary patient tissue area in the predetermined marking location and/or the predetermined marking trajectory while the base of the landmark guide is mated to the primary patient tissue area; and
removing the landmark guide from mating engagement with the primary patient tissue area while the first landmark and guidewire pin remain fixed in the patient tissue.
