Claims51
A method of fitting an articular implant to a knee joint of a patient, the method comprising:
- deriving a model from anatomical image data including articular anatomy of the patient's knee joint;
- selecting an articular implant from a catalog of existing articular implants having a range of sizes, wherein the articular implant includes a planar surface for abutting a resected bone surface;
- adapting the shape of the selected articular implant to fit the articular implant to the articular anatomy of the patient's knee joint;
- and
- designing a surgical cutting or drilling tool having a surface that substantially conforms to a surface of the knee joint and having one or more guides defining a cutting or drilling path with a predetermined position relative to the surface of the knee joint, wherein the tool facilitates the placement of the implant in a preferred position.

A method for optimizing the fit of an implant for a knee joint of a patient, the method comprising:
- obtaining anatomical image data including articular anatomy of the patient's knee joint;
- deriving a model of at least a portion of the knee joint from the anatomical image data including articular anatomy of the patient's knee joint;
- selecting a implant of appropriate shape or size from a database of articular implants having a range of sizes, wherein the implant includes a planar surface for abutting a resected bone surface;
- adapting the size or shape of the selected implant by manipulating the size or shape of the implant to fit the implant to the articular anatomy of the patient's knee joint;
- and
- designing a surgical cutting or drilling tool having a surface that substantially conforms to a surface of the knee joint and having guides defining a cutting or drilling path with a predetermined position relative to the surface of the knee joint to facilitate the placement of the implant in a preferred position.
