Cartilage defects are common pathologies and surgical cartilage repair shows promising results. In its post-operative evaluation, the magnetic resonance observation of cartilage repair tissue (MOCART) score is widely used. Within the present study a newly developed 3D-MOCART score was presented. 100 Knee MRIs in 60 patients were included during a routine MR follow-up examination at 3.0 Tesla MRI using an high-resolution isotropic 3D-true fast-imaging with steady-state-precession (True-FISP) sequence for the new 3D-MOCART score in the post-operative evaluation of patients after matrix-associated autologous chondrocyte transplantation. Finally, the results were compared to the conventional 2D-MOCART score using standard MR sequences.
