Abstract
A reconstructive structure for a cartilaginous element having a plurality of superimposed layers of a small intestine submucosa compressed and secured together and shaped to provide the multi-layered reconstructive element of the anatomical shape of the cartilaginous element to be constructed. The method of forming the reconstructive structure includes superimposing the planar layers of the small intestine compressing, securing and cutting to the desired shape. The superimposing is performed so as to maintain the layers substantially planar prior to compressing and securing. The method of reconstructing a cartilaginous element includes removing at least a portion, if not substantially all of the cartilaginous element, but leaving a seed portion, sculpturing the reconstructive structure to the anatomical shape of the cartilaginous element to be reconstructed; positioning the receptive element adjacent to the seed portion and securing it thereto. To reconstruct a joint having two bones separated by a cartilaginous material, the method includes removing any remaining portions of the cartilaginous material down to a bleeding bone site and positioning and securing the reconstructive ele…
