Fig. 4From: Dynamic viscoelastic characterisation of human osteochondral tissue: understanding the effect of the cartilage-bone interfaceStorage (a) and loss (b) stiffness for the cartilage-bone-system, isolated cartilage, and isolated bone specimens plotted against frequency from 1 to 90 Hz (mean ± 95% confidence intervals, (N = 5) with natural logarithmic regression trendlines). In total, 19 cartilage-bone cores, 19 cartilage, and 18 bone specimens from five femoral heads were tested. Results are displayed on a linear scaleBack to article page
