Figure 4From: Viscoelastic properties of bovine knee joint articular cartilage: dependency on thickness and loading frequency Thickness dependency of A (see equation 1 ) for knee joint cartilage. A second order polynomial curve (see equation 4) was fitted to the experimental data (R 2 = 51%; p < 0.05) as shown (solid line). The 95% confidence intervals are also included (dashed line).Back to article page
