FIG. 1.

(a) Macroscopic images of lesions at 6 weeks postoperatively; lesions of adjacent cartilage are visible in adult minipig specimens (*); scale bar = 4 mm. (b) Fluoroscopic image of an adult minipig stifle joint in tunnel and sagittal view; tibial and femoral growth plates are closed. (c) Fluoroscopic image of juvenile minipig stifle joint in tunnel and sagittal view; tibial and femoral physes are open, as indicated by arrow heads. (d) Macroscopic scoring at 6 weeks postoperatively according to Goebel et al., where higher scores represent a worse appearance (worst score = 20 points, best score = 0 points); full circles = adult minipigs; empty circles = juvenile minipigs.
