Abstract
An orthopaedic implant includes a femoral component having a metallic zirconium and niobium coating disposed therein. A method of making the femoral component using direct energy deposition or co-molding is also disclosed.
Claims19
A knee prosthesis comprising:
- a femoral component configured to be coupled to a distal end of a patient's femur, the femoral component comprising
- (i) a substrate comprising a titanium alloy having (a) a condylar surface, and (b) a bone-facing surface opposite the condylar surface, and
- (ii) an articular layer disposed on the condylar surface, the articular layer comprising an alloy of zirconium and niobium,
- wherein a portion of the alloy of zirconium and niobium is oxidized zirconium, and
- wherein the oxidized zirconium forms an outer surface of the femoral component.
2 more elements
A method of forming a femoral component of a knee prosthesis, the method comprising the step of:
- utilizing direct energy deposition to apply an articular layer to a condylar surface of a femoral component.
A method of forming a femoral component of a knee prosthesis, comprising:
- injecting a first mixture comprising a zirconium alloy and a binder agent into a first mold to form an articular layer;
- and
- injecting a second mixture comprising a titanium alloy and a binder agent into a second mold to form a substrate,
- sintering the articular layer and substrate together, and oxidizing a portion of the articular layer.
1 more element
The method of 15, wherein the first mixture comprises at least about 93% by weight zirconium and up to about 7% by weight niobium.
