Abstract
A unicondylar femoral component for use in a partial knee arthroplasty. A femoral component of the present invention comprises a post and a flange having a predetermined angle there between whereby a clamping force is placed on a patient's distal femur to hold the implant in place. The implant further comprises a porous layer on its bone contacting surface. In an alternative embodiment the femoral component is attached to the distal femur at least two threaded fasteners.
Claims10
A femoral component of a unicondylar endoprosthetic knee, wherein said femoral component is attached to a distal femur during a partial knee arthroplasty, the component comprising:
- a convex arcuated articulating surface having a desired shape;
- a bone contacting surface disposed opposite the articulating surface, wherein the bone contacting surface comprises a post extending from the bone contacting surface;
- a flange disposed at the anterior end of the femoral component such that an angle of between about 1 degree and about 15 degrees is formed between the flange and the post.
A femoral component for a unicondylar endoprosthetic knee implant comprising:
- a convex articulating surface having a desired shape;
- and
- a bone contacting surface disposed opposite the articulating surface, wherein the bone contacting surface comprises a posterior post extending from the bone contacting surface and an anterior post extending from the bone contacting surface such that an angle of between about 1 degree and about 15 degrees is formed between the anterior post and the posterior post.
