Abstract

Methods and apparatuses for attaching soft tissue and/or bone to orthopaedic implants. In one exemplary embodiment, the methods and apparatuses are used to attach soft tissue and/or bone to a proximal tibial implant. In another exemplary embodiment, the methods and apparatuses are used to attach soft tissue and/or bone to a proximal femoral implant.

Claims

1. A segmental tibial orthopaedic implant, comprising:

a body; and

a porous surface attached to at least a portion of said body to facilitate attachment of soft tissue structures and/or bone to said body.

2. The segmental tibial orthopaedic implant of claim 1, further comprising at least one washer connected to said body, said washer to facilitate moving the soft tissue structures into contact with said porous surface.

3. A segmental femoral orthopaedic implant, comprising:

a body; and

a porous surface attached to at least a portion of said body to facilitate attachment of soft tissue structures and/or bone to said body.

4. The segmental femoral orthopaedic implant of claim 3, further comprising at least one washer connected to said body, said washer to facilitate moving the soft tissue structures into contact with said porous surface.
