Figure 1From: Enzymatic digestion of articular cartilage results in viscoelasticity changes that are consistent with polymer dynamics mechanismsExperimental Protocol. Middle-zone patellofemoral bovine calf cartilage explants were harvested and cultured overnight. Samples were subjected to baseline mechanical testing and randomly assigned to an enzyme- treatment or control group. Mechanical testing was performed again after 1 and 2 days of exposure to the treatment.Back to article page
