Cartilage Repair and Subchondral Bone Migration Using 3D Printing Osteochondral Composites: A One-Year-Period Study in Rabbit Trochlea

<table>Collagen-I immunohistochemical staining of repaired cartilage. Collagen-I staining was faintly positive at 24 and 52 weeks, which was comparable with sham control group, while tissue sections at 16 weeks were positively stained with collagen I, bar = 100 <i>μ</i>m.</table>
