Abstract

An orthopaedic augment includes a porous material, which is removably attached to a medical implant. The porous material has a bone ingrowth surface for interfacing with an existing bone material and another surface for interfacing with the medical implant.

Claims (19)

1. An orthopaedic augment, comprising a porous material removably attachable to an interface surface of a medical implant, said porous material having a bone ingrowth surface for interfacing with an existing bone material and another surface for interfacing with said medical implant, said medical implant including a post extending from said interface surface past said bone ingrowth surface of said porous material, said post having a solid exposed surface.

2. The orthopaedic augment according to claim 1 , wherein said porous material is removably attached to said medical implant with at least one fastener.

3. The orthopaedic augment according to claim 2 , wherein said fastener is formed from polyether ether ketone (PEEK).

4. The orthopaedic augment according to claim 2 , said at least one fastener being configured to thread into an opening on said medical implant.

5. The orthopaedic augment according to claim 1 , wherein said porous material is one of a polymer scaffold, allograft bone, autograft bone, and cuttable metal scaffold.

6. The orthopaedic augment according to claim 5 , wherein said porous material is a polymer scaffold, said polymer scaffold being formed from polyether ether ketone (PEEK).

7. An orthopaedic implant, comprising:

a main body having an interface surface;

a porous augment removably attached to said interface surface of said main body, said porous augment having a bone ingrowth surface for interfacing with a bone material and another surface coupled with said main body; and

a post extending from said interface surface of said main body past said bone ingrowth surface of said porous augment, said post having a solid exposed surface.

8. The orthopaedic implant according to claim 7 , wherein said porous material is removably attached to said main body with at least one fastener.

9. The orthopaedic implant according to claim 8 , wherein said at least one fastener is formed from polyether ether ketone (PEEK).

10. The orthopaedic implant according to claim 7 , said porous augment being formed from one of a polymer scaffold, allograft bone, autograft bone, and cuttable metal scaffold.

11. The orthopaedic implant according to claim 10 , wherein said porous augment is a polymer scaffold, said polymer scaffold being formed from polyether ether ketone (PEEK).

12. The orthopaedic implant according to claim 7 , wherein said main body includes a porous layer of material to which said other surface of said porous augment is coupled.

13. The orthopaedic implant according to claim 7 , wherein said main body is one of a tibial tray and a femoral implant.

14. The orthopaedic implant according to claim 13 , wherein said main body is a femoral implant and said porous augment is removably attached with said femoral implant using a post.

15. The orthopaedic implant according to claim 7 , wherein said porous augment has at least two thicknesses.

16. The orthopaedic implant according to claim 15 , wherein said porous augment has a first portion having a first thickness and a second portion adjacent said solid post, said second portion having a second thickness which is less than said first thickness of said first portion.
