Methods and apparatus for performing arthoplasty utilizes a plurality of apertures created in a bone, each aperture having a cross section defined perpendicular to an axis of the aperture that intersects a plane of a resected surface to be created in the bone and also intersects a peripheral rim border that externally delineates the resected surface. A pin feature is inserted into each of the plurality of apertures and the resected surface is created by guiding a cutting tool along at least a line of contact of the pin features. An implant can then be attached to the resected surface.
