Figure 2From: Viscoelastic properties of bovine knee joint articular cartilage: dependency on thickness and loading frequency Thickness dependent loss stiffness of knee joint cartilage at 1 Hz. A second order polynomial curve (see equation 2) was fitted to the experimental data (R 2 = 69%; p < 0.05) as shown (solid line). The 95% confidence intervals are also included (dashed line).Back to article page
