Table 2: Magnetic resonance Observation of Cartilage Repair Tissue (MOCART) 2.0 evaluation. Figure 4: MRI evaluation at 9 years’ follow-up of a medial femoral condyle lesion treated with matrix-assisted autologous chondrocyte transplantation in a 39-year-old woman. Sagittal 3D “Cube” PD (**a**) and coronal PD FAT SAT (**b**) demonstrate a good filling of the defect (arrows) and integration into adjacent cartilage, a homogeneous structure and a normal signal intensity of the repair tissue. Moreover, no significant bony defect, bony overgrowth, or major subchondral changes were detected.
