Abstract
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 ultrafiltration by cartilage as a possible mechanism in synovial lubrication.
