Supplementary Material

Wayne scoring system is modified cartilage assessment system of the Visual Histological Scale of the International Cartilage Repair Society(ICRS). The scale is composed of gross appearance and histology scores. For gross score evaluation, four items were involved including defect coverage, tissue color, defect margin, surface, with a total score of 16 points. Histology score is composed of matrix points, cell distribution points, smoothness points of the surface, Safranin O stain points, and Safranin O-stained area points, with a full histological score of 19 points.
