Abstract
Methods and apparatuses for attaching soft tissue and bone to orthopaedic implants. The orthopaedic implants are provided with a woven ingrowth material to facilitate attachment of soft tissue and bone thereto. In one embodiment, the woven ingrowth material is formed as a patch or region of woven material attached to the implant. In another embodiment, a sleeve formed of woven ingrowth material encompasses the majority of the implant.
Claims23
An orthopaedic implant assembly for positioning in a bone adjacent a tissue structure, comprising:
- an orthopaedic implant suitable for replacing at least a portion of the bone;
- a woven material having a first, body portion that is fixedly secured to said orthopaedic implant to prevent relative movement between said body portion of said woven material and said orthopedic implant, and a second, extension portion that extends freely away from said orthopaedic implant;
- and
- a fastener sized for securement into said woven material to operably secure the tissue structure to said orthopaedic implant;
- whereby when said orthopaedic implant is positioned adjacent the tissue structure, said woven material is accessible outside the bone and the tissue structure is securable to said orthopaedic implant via attachment of said fastener into said woven material.
An orthopaedic implant assembly for positioning in a tibia adjacent a tissue structure, comprising:
- a tibial implant suitable for replacing at least a portion of the tibia, said tibial implant comprising:
- a body having a proximal end, a distal end opposite said proximal end, an anterior surface, a posterior surface opposite said anterior surface, a medial surface, and a lateral surface opposite said medial surface;
- and
- a tray coupled to said proximal end of said body;
- a woven material having a first, body portion that is fixedly secured to said tibial implant to prevent relative movement between said body portion of said woven material and said tibial implant, and a second, extension portion that extends freely away from said tibial implant;
- and
- a fastener sized for securement into said woven material to operably secure the tissue structure to said tibial implant;
- whereby when said tibial implant is positioned adjacent the tissue structure, said woven material is accessible outside the tibia and the tissue structure is securable to said tibial implant via attachment of said fastener into said woven material.
A method for attaching a tissue structure to an orthopaedic implant, the orthopaedic implant implantable in a bone, the method comprising the steps of:
- providing an orthopaedic implant with a woven material secured thereto, said woven material having a first, body portion that is fixedly secured to said orthopaedic implant to prevent relative movement between said body portion of said woven material and said orthopedic implant, and a second, extension portion that extends freely away from said orthopaedic implant;
- positioning said orthopaedic implant in the bone such that said woven material is accessible outside the bone;
- and
- securing the tissue structure to said woven material by connecting a fastener directly into said woven material.
