Patient-modified implant

摘要

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.

主权项

1. 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.
