Abstract
An orthopaedic device for repairing and regenerating cartilage includes a plug configured to be positioned in a hole formed in the cartilage and an anchor configured to support the plug. One or both of the plug and the anchor may be formed from naturally occurring extracellular matrix such as small intestine submucosa. A method for repairing and regenerating cartilage is also disclosed.
Claims23
A device for repairing a diseased or damaged portion of articular cartilage on a bone of a joint, the cartilage having been prepared by forming an opening therein to remove the diseased or damaged portion, the device comprising:
- a plug configured to be positioned in the opening formed in the cartilage, the plug defining a body of unseeded naturally occurring extracellular matrix, and
- an anchor configured to position and hold the plug in the opening.
A device for repairing a diseased or damaged portion of articular cartilage on a bone of a joint, the cartilage having been prepared by forming an opening therein to remove the diseased or damaged portion, the device comprising:
- a plug configured to be positioned in the opening formed in the cartilage, the plug defining a body of naturally occurring extracellular matrix seeded with at least one of the following:
- a bioactive agent, a biologically derived substance, cells, a biological lubricant, a biocompatible polymer and a biocompatible inorganic material, and
- an anchor configured to position and hold the plug in the opening.
A device for repairing a diseased or damaged portion of articular cartilage on a bone of a joint, the cartilage having been prepared by forming an opening therein to remove the diseased or damaged portion, the device comprising:
- a plug configured to be positioned in the opening formed in the cartilage, wherein (i) the plug comprises naturally occurring extracellular matrix, and (ii) the plug has an outer articular surface and one or more side surfaces extending therefrom,
- an anchor configured to position and hold the plug in the opening, and
- a cover disposed over at least part of the articular surface of the plug, wherein the cover comprises one or more sheets of naturally occurring extracellular matrix.
