A method of manufacturing a joint implant for a joint of a specific patient includes obtaining a three-dimensional image of a bone of the joint of the specific patient from medical imaging scans of the bone of the patient and determining on the three-dimensional image a resection plane for contacting a corresponding planar surface of the joint implant for the specific patient. Each SASMAS is confined in its own guide with respect to an associated SPSTB. In one embodiment, the registers in the plurality of registers are in series or substantially in series.
