Cartilage Repair and Subchondral Bone Migration Using 3D Printing Osteochondral Composites: A One-Year-Period Study in Rabbit Trochlea
Figure 4
Histology and Wayne score of repaired cartilage: pictures in Figure 4(a) were merged together from several individual photos in order to get a full view of panorama, bar = 500 μm; pictures in Figure 4(b) were magnification of the part in dotted boxes of Figure 4(a), bar = 200 μm; tidemark formation was presented in Figure 4(b), (as blank arrows showed); Figure 4(c) showed comparison of Wayne score in each group, (). Due to sample preparation process, CaP particles of ceramic were dissolved during the decalcification procedure with empty spots left; PEG hydrogel was also dissolved during dehydration process. The location of hydrogel part was marked with red dashed box in stained slices; decalcified ceramic was surrounded by repaired bone tissue.
