Abstract
A modular knee prosthesis system comprises a distal femoral articulation component, a distal augment, a posterior augment and a first connector for securing at least one of the augments to the distal femoral articulation component through a bore in the augment and an opening in the distal femoral articulation component. The distal femoral articulation component has a distal bone-facing surface, a posterior bone-facing surface and an opening. The openings into the bores of the augments are in the medial or lateral side surface of the augment. Both augments can be mounted and removed from the distal femoral articulation component from either the medial or lateral side.
Claims26
A modular knee prosthesis system comprising:
- a distal femoral articulation component having a pair of curved distal condylar articulating surfaces, a pair of curved posterior condylar articulating surfaces, a distal bone-facing surface and a posterior bone-facing surface;
- an augment sized and shaped to be received on one of the bone-facing surfaces of the distal femoral articulation component, the augment including a first surface, a second surface spaced from and generally opposite to the first surface and side surfaces extending between and connecting the first surface and the second surface, a body between the first and second surface, at least one of the side surfaces having an opening into a bore extending from the side surface through the body and through another surface of the augment;
- and
- a first connector for securing the augment to the distal femoral articulation component;
- wherein the distal femoral articulation component has an opening to receive the connector to selectively mount the augment to the distal femoral articulation component.
