Elasticity of Articular Cartilage: Effect of Ions and Viscous Solutions

The deformability of articular cartilage is increased by cations, more so by polyvalent than monovalent ones. Trivalent cations also depress elastic recovery. Failure of viscous solutions to alter the elastic behavior suggests ultra-filtration by cartilage as a possible mechanism in synovial lubrication.
