1. A patient-specific resection guide locator comprising:
a body;
a first positioning member extending from the body, the first positioning member having a bone engaging surface disposed on a side of the first positioning member, the bone engaging surface being configured for complementary matching with a set of anatomical surface features of a selected region of the patient's natural bone;
a second positioning member extending from the body, the second positioning member being distally disposed from the first positioning member; and
an anteromedial flange extending from the body between the first positioning member and the second positioning member,
wherein the anteromedial flange is disposed at an offset angle relative to a reference sagittal plane of the body, the reference sagittal plane of the body being disposed coplanar with a height dimension and width dimension of the body at a location wherein a reference flange plane intersects the reference sagittal plane, the reference flange plane being coplanar with a flange length and a flange height of the anteromedial flange, and
wherein the anteromedial flange has areas defining a fixation pin through bore extending through the anteromedial flange at a pin angle, the pin angle being formed by the intersection of a through bore length dimension and the reference flange plane.
