Magnetic resonance imaging (MRI) four years after implantation of BioSeed^®-C. (a) Out of 17 patients, 11 patients, including this one, showed complete filling of the defect four years after implantation of BioSeed^®-C. (b) Five patients, including this one, showed more than 50% defect filling but not complete defect filling. (c) One patient showed less than 50% defect filling (black arrowhead). The repair tissue gives a slightly altered MRI signal, and transosseous drill holes are still evident (white arrowheads).
