Fixation potential of two techniques, autologous fibrin glue (top) and PCL osteal anchor (bottom), 14 days after implantation. Reinforced chondral constructs appeared still in place in two of three cases; however, the scaffolds looked as if they were starting to slip out proximally (A). micro-CT of AFG fixation showed some bone resorption (B), confirmed by the HE staining (C), which showed loss of architecture directly underneath the defect with significant infiltration of neutrophil granulocytes and fibroblasts. Constructs fixated with the PCL anchor were all still in place (D), and micro-CT imaging showed a conserved trabecular architecture surrounding the construct (E). The chondral portion of the defect appears filled with repair tissue with a predominance of fibroblasts (F) (Black bar = 1mm). Color images available online at www.liebertpub.com/tec
