Grafts were fixated in formalin (4% formaldehyde), decalcified, and processed into standard 8\u2010\u03bcm\u2010thick hematoxylin and eosin\u2013and Toluidine Blue\u2013stained sections. These were assessed for cartilage thickness, shape of articular surface, and 13 histologic parameters of the International Cartilage Repair Society II.
