Abstract
An orthopedic implant includes a first portion including at least one feature modified to be patient-specific and match the anatomy of a specific patient from a three-dimensional digital image of a patient's joint using computer modeling. The orthopedic implant includes a non-custom inner bone-engaging surface including a plurality of planar surfaces configured for engagement with non-custom bone cuts.
Claims20
An orthopedic implant comprising:
- a first portion including at least one feature modified to be patient-specific and to match the anatomy of a specific patient based on a three-dimensional digital image of a patient's joint using computer modeling;
- and
- a non-custom inner bone-engaging surface including a plurality of planar surfaces configured for engagement with non-custom bone cuts.
An orthopedic implant comprising:
- a non-custom inner bone-engaging surface including a plurality of planar surfaces configured for engagement with standard size femoral bone cuts prepared for a non-custom femoral implant;
- and
- a first portion configured during a preoperative plan to have a patient-specific feature and to closely match a corresponding portion of a femur of a specific patient based on a three-dimensional digital image of a patient's joint using computer modeling, wherein the patient-specific feature is obtained by modifying a digital image of the non-custom femoral implant without modifying the plurality of planar surface of the inner bone-engaging surface.
An orthopedic implant comprising:
- a tibial bearing including a non-custom portion;
- and
- a tibial tray including a non-custom locking mechanism configured to be coupled with the non-custom portion of the tibial bearing, wherein the tibial tray has a patient-specific profile configured during a preoperative plan to closely match a corresponding profile of a tibia of a specific patient based on a three-dimensional digital image of a patient's joint using computer modeling, wherein the patient-specific profile of the tibial tray is obtained by modifying a digital image of a non-custom tibial implant without modifying the non-custom locking mechanism.
