- aSuperficial zone of cartilage is from 0 to 8 μm; bmid zone is from 8 to 53 μm; cdeep zone is from 53 to 100 μm; the zone thicknesses were determined by polarized light microscopy; dsignificance was calculated using the two-tailed, paired Student t test (α = 0.05). PG, proteoglycan; SD, standard deviation.
