TL;DR: It is concluded that optical and needle probe methods can be used interchangeably when determining shear modulus of articular cartilage with indentation tests, however, if high area-aspect ratios (indenter radius-to-cartilage thickness ratios) are used in the indentation measurements uncertainty in shearmodulus may be markedly increased due to possible errors in the measurement of cartilage thickness.

TL;DR: Today's quantitative microscopic methods in combination with the fibril-reinforced poroviscoelastic model are feasible methods to characterize the structure-function relationships of articular cartilage.

TL;DR: Results reveal that changes in the quantitative MRI parameters studied are indicative of structural and compositional alterations as well as the mechanical impairment of spontaneously degenerated articular cartilage.

TL;DR: Effects of immobilization with a splint for 11 weeks on the stiffness of the articular cartilage in the canine knee were investigated and influenced the quality and quantity of articular Cartilage.

TL;DR: Experimental evidence highlights the sensitivity of Gd‐DTPA‐enhanced T1 imaging of articular cartilage to reflect spatial changes in cartilage PG concentration in normal and degenerated tissue.
