Formation of intralesional osteophytes at 6 month after surgery using μMRI at 9.4 T. Intralesional osteophytes (arrow) that arise from the subchondral bone plate into the cartilaginous repair tissue were observed in four osteochondral samples after marrow stimulation. Asterisks (*) indicate the extent of the cartilage defect. Subsequent coronal planes (a, b). SGE sequence, isotropic voxel size 120 μm3. Scale bar = 4 mm.
