ABSTRACT:
Use of a biological material containing: e) a three-dimensional matrix based on a hyaluronic acid derivative and optionally f) chondrocytes and/or mesenchymal cells partially or completely differentiated towards chondrocytes for the preparation of a graft to be surgically implanted into a joint cartilage damaged by or to be protected against a degenerative and/or inflammatory pathology.
