The aim of our study was to assess the repair tissue
structure after a matrix associated autologous
chondrocyte transplantation technique using biochemical
MRI. Fourteen knees of 14 patients were assessed in that
cross-sectional study at a mean follow up of 2.0 0.9
years. The results demonstrated a zonal variation not
only in T2-maps, but also in dGEMRIC images. This
suggests a gradual increase in proteoglycan content of
repair tissue from the superficial to the deep layer.
