Subchondral bone as a novel target for regenerative therapy of osteochondritis dissecans: A case report

Figure 1 Sequential coronal and sagittal T2-weighted magnetic resonance imaging images at baseline and 4 mo. The focal subchondral bone and cartilage defect (orange circle) improved progressively over time, and the whole-organ magnetic resonance imaging score improved from 25 at baseline to 14 at 4 mo. Initial integration was observed between regenerative and native subchondral bone and cartilage. The loose body still existed.
