ABSTRACT:
A method for modifying the surface properties of tissue in vivo is described The method comprises forming a liquid crystalline matrix on the tissue surface wherein the matrix comprises a tissue surface component In one embodiment there is provided a method for improving the bonding of surgical glues and cements to cartilage and other synovial fluid wetted tissue surfaces. Such surfaces are contacted with a composition comprising a poly(hydroxy substituted amino acid) to form a liquid crystalline matrix on the tissue surface The matrix is readily removed to provide a tissue surface that exhibits improved bonding with surgical glues.
