Claims22
A method of repairing a chondral or osteochondral defect using a demineralized bone fiber (DBF) implant composition having a contiguous shape comprising a peg portion and a sheet portion, the method comprising:
- creating a cavity in a bone area of a cartilage defect;
- and
- placing the peg portion into the bone cavity, thereby placing the connected sheet portion in contact with the chondral defect.
An implant composition for repairing a chondral defect proximal to a bone or an osteochondral defect in a bone, the composition comprising:
- a plurality of fibers cut from demineralized bone, the plurality of fibers forming a contiguous shape comprising a peg portion and a sheet portion.
A method of cartilage repair using a demineralized bone fiber (DBF) implant composition having a cylinder shape, the method comprising:
- optionally preparing a bleeding bone bed on the base of the chondral defect using a microfracture technique;
- creating a cavity:
- i) in a bone area facing a chondral defect;
- or ii) in an osteochondral defect area of a bone;
- and
- placing the implant composition into the bone cavity thereby placing the connected sheet portion in contact with the chondral defect or the osteochondral defect.
