The
study assessed the long-term status of isolated cartilage lesions in the knee
after ACT using dGEMRIC. Scans were obtained from 31 patients (5 bilateral
lesions) total of 36 lesion sites, representing an f/u period of 9.5 to18.5
years post-implant. The dGEMRIC Index of the implant was greater than 90% of
the value of the dGEMRIC Index for surrounding native tissue in 70% of cases,
even more than 10 years after the implantation.
