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 contactin
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. The method includes determining a three-dimensional image of a porous structure of a bone layer along the resection plane from the medical imaging scans of the patient. The joint implant is manufactured with a layer of a patient-specific porous construct attached to the planar surface of the joint implant. The layer of the patient-specific porous construct substantially replicates the porous structure of the bone layer of the specific patient.
