Abstract
The invention disclosed is a method for repairing focal arthritic defects in a mammalian joint, especially in a human knee. The method involves the steps of forming a roughened, bleeding surface of cancellous bone within the defect; forming a plug of osteocartilaginous tissue from an undamaged site within the joint or from another joint; removing the plug from the undamaged site; and inserting the plug into the defect, positioning the plug against the roughened bleeding surface, and holding the plug in place for a time sufficient to allow a blood clot to form between the plug and the roughened bleeding surface, whereby the plug is secured by adhesive properties of the clot.
