The integrity of cartilage adjacent to repair tissue was
assessed with zonal T2-mapping. Twelve months after
MACT, the mean T2 values in cartilage surrounding the
repair tissue were significantly higher than in the
normal cartilage, and significantly lower than in the
repair tissue zone (both p<0.001). Two years after the
procedure, no significant differences between the
regional T2 values could be observed. The results
indicate that cartilage surrounding the transplant shows
early degenerative changes one year after MACT. If this
degeneration predates the MACT, cartilage
transplantation may have a positive influence on the
adjacent cartilage.
