Figure 6From: Improved cartilage integration and interfacial strength after enzymatic treatment in a cartilage transplantation modelAverage force-displacement curves of push-out tests with standard error bars for untreated (n = 5) and enzyme-treated (n = 6) curves, respectively. Failure strength in the enzyme-treated group was significantly higher (+58%). The failure of the curve to return to zero can be explained by friction between pushed-out core and sample holder.Back to article page
