Claims14
A patient-specific bicompartmental knee implant for implantation into a patient's knee joint, the implant comprising:
- a body having a condylar portion and a trochlear portion,
- wherein the condylar portion has a shape generally resembling a surface of a condyle of the patient's knee joint and the trochlear portion having a shape generally resembling the surface of a trochlea of the patient's knee joint, wherein the trochlear portion includes a patellofemoral (PF) region having a standard coronal curvature selected from a family of standard curvatures and a patient-specific sagittal curvature;
- the condylar portion further having an articular surface, wherein at least a portion of the articular surface is configured to have a three-dimensional shape that includes articular shape information of a corresponding portion of the condyle of the patient's knee joint;
- and
- the condylar portion further having a bone-facing surface opposite the articular surface, wherein at least a first portion of the bone-facing surface is planar and at least a second portion of the bone-facing surface substantially matches a corresponding portion of an articular surface of the patient's knee joint.
