Implant with patient-specific porous structure
First Claim
1. An orthopedic implant manufactured for a specific patient comprising:
- a femoral knee implant core having an interior multiplanar surface including a plurality of planar surfaces configured to correspond to a plurality of corresponding resection planes of a distal femoral bone of the specific patient; and
a patient-specific porous construct including a plurality of layers attached to corresponding planar surfaces of the femoral knee implant, each layer constructed to replicate a three-dimensional porous structure of a bone layer along a corresponding resection plane of femoral bone, the porous structure determined from medical imaging scans of the un-resected femoral bone;
wherein the patient-specific porous construct three-dimensionally varies throughout each layer in a patient-specific manner according to the three-dimensional porous structure of the bone layer.

Abstract
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.

11. An orthopedic implant manufactured for a specific patient comprising:
-
an implant core comprising; an outer joint-facing surface; and an inner bone engagement surface having at least one planar surface constructed to correspond to a corresponding resection plane of a bone of the specific patient; and a patient-specific porous construct including a layer attached to the planar surface of the orthopedic implant, the patient-specific porous construct mirroring a porous structure of a bone layer at the resection plane such that the layer of the patient-specific porous construct is an inverse of the porous structure of the bone layer of the bone at the resection plane. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
