area of the in situ bioprinting group was continuous and bone. For the blank group, the signal of the cartilage was
uniform, and the fusion with the surrounding cartilage discontinuous. According to the MRI results, a more
tissue was proper. With regard to the direct implantation satisfactory regeneration result was seen in the in situ
group, an abnormal signal was detected in the subchondral bioprinting group than in other groups. As shown in Figure
