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

<table>Collagen-II immunohistochemical staining of repaired cartilage. Collagen-II staining in 16, 24, and 52 weeks was intensively expressed, which is comparable to sham control group, while tissue sections at 16 weeks showed limited expression, bar = 100 <i>μ</i>m.</table>
