Figure 5

Histological stains. Histological stains of the biopsies of cartilage and underlying bone that were taken from the site of the chondral allograft implantation on the trochlea at nine months following the repair (repair tissue) and from the trochlea of a cadaver (healthy tissue, for comparison). Scale bars = 500 m.
