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.

A standard acetabular prosthesis blank is selected from a plurality of pre-manufactured blanks, and includes a cup portion and at least one flange. The method includes shaping the blank acetabular prosthesis using a custom deforming fixture such that the shaped acetabular prosthesis has a final shaped geometry and measurement parameters to substantially match the patient's pelvic anatomy relative to the patient's acetabulum.

Abstract: A method of preparing a knee joint for a prosthesis in a patient includes mating a patient-specific three-dimensional curved inner surface of a femoral alignment guide onto a corresponding three-dimensional femoral joint surface of the patient. The patient-specific three-dimensional curved inner surface is preoperatively configured from medical scans of the knee joint of the patient. First and second holes are drilled into an anterior portion of the femoral joint surface through corresponding first and second guiding apertures of the femoral alignment guide.

Abstract: A prosthesis for replacing a knee joint between a femur and a tibia can include a femoral component, a tibial component, a bearing and a yoke assembly. The yoke assembly can have a yoke disposed between the bearing and the femoral component and an axle having an axle axis. The axle can hingedly couple the yoke with the femoral component. Rotation of the femoral component about a rotation axis that is perpendicular to the axle axis causes concurrent rotation of the yoke about the rotation axis.

Abstract: A method of positioning a femoral cutting guide on a distal end of a femur establishes at least a first reference plane to perform a distal femoral planar cut. The method includes inserting a mounting member into an intramedullary canal of the femur and coupling a bridge member to the mounting member. The method also includes placing a cutting guide member over a medial anterior portion of the distal femur. The cutting guide member has a first channel that establishes the first reference plane. The bridge member has a bridge channel. A wall of the bridge channel is inserted into the first channel of the cutting guide member. A mounting mechanism generates resistance between the bridge member and the cutting guide member. The resistance is overcome by positioning the cutting guide member relative to the femur.

Abstract: A prosthetic device for an anatomical feature includes a prosthetic member able to be fixed to the anatomical feature. The device also includes a bearing including a bearing surface able to support an articulating surface for articulation thereon. Additionally, the device includes a bearing restraining member that limits movement of the bearing relative to the prosthetic member at a first time. The bearing restraining member also allows for increased movement of the bearing relative to the prosthetic member at a second time without surgical intervention.

Abstract: A patient-specific alignment guide includes a three-dimensional engagement surface customized in a pre-operating planning stage by computer imaging to closely mate and conform to a corresponding bone portion of a patient's elbow joint. The patient-specific alignment guide defines a first longitudinal guiding bore aligned with a reference axis associated with the elbow joint of patient when the alignment guide is mounted onto the corresponding bone portion.

Abstract: An orthopedic device includes a monolithic patient-specific guide. The patient-specific guide includes a three-dimensional contact surface preoperatively configured from medical scans of a specific patient as a negative surface of a medial portion of a proximal femoral bone of the patient according to a preoperative surgical plan for the patient. The guide also includes a proximal planar surface configured for guiding a resection of a femoral neck of the patient, and a scale formed on the planar surface. The scale is configured for indicating a preoperatively planned femoral version of a femoral stem implant and deviations therefrom.

Abstract: A method is disclosed for repairing a defect in an anatomical feature, the defect having a surface that defines a volume. The method includes receiving imaging data obtained using a medical imaging technique. The imaging data represents the anatomical feature. In one example, the method further includes creating a three-dimensional (3D) model of a mold for an implant based on the imaging data. The mold includes a cavity that replicates the volume of the defect. In another example, the method further includes creating a 3D model of an implant based on the imaging data. The implant is configured to fill the volume of the defect. In various implementations, the mold, the implant, and/or a replica of the implant are formed based on the 3D model of the mold or the 3D model of the implant. Guides and implants corresponding to the method are also disclosed.

Abstract: A glenoid guide has an upper surface and a lower surface, wherein the lower surface is a patient-specific surface configured as a negative surface of a glenoid face based on a three-dimensional image of a shoulder joint of a patient reconstructed preoperatively from image scans of the shoulder joint of the patient.
