Abstract: The rheological characteristics of an artificial synovia mainly consisting of hyaluronic acid prepared by editors was discussed. The influence of the additives, γ-globulin and Lα-DPPC Phosphatide on the rheological characteristics and lubrication behavior of the artificial synovia was analyzed. Then a discussion on the new lubrication mechanism combining the surface properties of tribology slier pairs with the rheological characteristics of the synovial fluid was further launched.
