| Description
| - The properties and behaviour of articular cartilage (AC) have been studied from numerous aspects. A number of biomechanical models of the properties and behaviour of AC are available today. The traditional model presents cartilage as homogeneous, isotropic and biphase material. There also exist models of transversally isotropic biphase cartilage material, non-linear poroelastic cartilage material, models of poroviscoelastic and hyperelastic cartilage material, models of triphase cartilage material, and other models. The published models differ, more or less, by the angle of their authors' view of the properties and behaviour of articular cartilage during its loading. The system behaviour of AC very depend on nonlinear properties of synovial fluid (SF). Certain volumes of SF are moveable components during the mechanical loading in the peripheral zone of AC. Biomechanical properties of peripheral zone of AC are significantly influenced by change of SF viscosity due to mechanical loading. Our research has been focused on analyses of residual strains arising in AC at cyclic loading and on the viscous properties of SF. Residual strains in articular cartilage contribute the preaccumulation of articular surfaces by synovial fluid. SF reacts very sensitively to the magnitude of shear stress and to the velocity of the rotation of the femoral and tibial part of the knee joint round their relative centre of rotation when the limb shifts from flexion to extension and vice versa. Shear stresses decrease aggregations of macromolecules of hyaluronic acid in SF.
