We evaluated long-term magnetic resonance imaging (MRI) features of Knee Osteochondral Autologous Transplantation (OAT)-Mosaicplasty and correlated MRI findings and clinical outcome. Twenty-four patients (mean age 29.9 ± 8.7, 70.8% male) undergoing arthroscopic OAT between 1997 and 2000 were prospectively enrolled. The International Cartilage Repair Society (ICRS)/International Knee Documentation Committee (IKDC) scores and Tegner scores were employed for clinical evaluation. The magnetic resonance observation of cartilage repair tissue (MOCART) was utilized for description and assessment of the repair tissue. Median follow up was 113 months (interquartile range [IQR] 106-122). MRI showed good survival of grafted cartilage in 62.5% of patients. The integration of the graft was complete in 75% of cases, while the repaired tissue was intact in 62.5% and had an homogeneous structure in 70.8%. The MOCART score significantly correlated with objective and subjective scores (p = 0.003 and p = 0.002). Contrastingly, overall MOCART showed no correlation with the Tegner score. MRI revealed to be a powerful tool for non-invasive long-term assessment of OAT.
