1. A guide for preparing an implant site to replace a defect in a tibial surface, comprising:
a jig having a body portion having a first passageway and a second passageway defined therein, wherein the first and second passageways are generally parallel to each other and wherein the first and second passageways each are generally cylindrical;
a first alignment pin and a second alignment pin configured to be advanced through the first passageway and the second passageway, respectively; the first and second alignment pins configured to be advanced into a tibia bone beneath the defect in a tibial surface; wherein the first and second alignment pins each include a depth feature configured to provide a visual indication of the depth of each respective one alignment pin into the tibia bone; and
a spoon member coupled to the jig, the spoon member having a generally convex base portion having a contour generally corresponding to a contour of the tibial surface; wherein positioning the spoon member on the tibial surface causes the first and second passageways and the first and second alignment pins to be positioned beneath the defect in the tibial surface.
