Claim One:
1. A device for use in joint replacement surgery, the device comprising: a patient-specific jig having a body having a shape corresponding to three dimensional data of first and second resected planar surfaces of a bone of a patient according to a preoperative plan, the first resected planar surface of the bone having a first size and shape, the second resected planar surface having a third size and shape; the body including first and second bone facing planar surfaces, the first bone facing planar surface configured with a second size and shape that matches the first size and shape of the first resected planar surface of the bone of the patient according to the three dimensional data and the second bone facing planar surface configured with a fourth size and shape that matches the third side and shape of the second resected planar surface of the bone of the patient according to the three dimensional data; an outermost perimeter of the body surrounding the first and second bone facing planar surfaces and sized and shaped to nestingly mate with a non-resected perimeter of the resected planar surface of the bone of the patient in a single position according to the three dimensional data; and a plurality of individual alignment members extending from the body outward from the outermost perimeter, the plurality of alignment members including a respective alignment surface configured to nestingly mate in a single position with a respective portion of non-resected bone adjacent the first resected planar surface according to the three dimensional data of the bone structure of the patient.
