<P>PROBLEM TO BE SOLVED: To provide a biomimetic biomaterial for an artificial cartilage which promotes connecting and fixing power to an animate bone such as a centrum or the like and prevents fine powder to occur by friction. <P>SOLUTION: The biomaterial 10 for the artificial cartilage is made of layers of plates 2 with many penetration holes 2a and 2b perforated in a direction of the thickness and the plate 2 is made of a polymer with in-vivo decomposition absorbability which includes bioceramic powder with bioactivity at one side or both sides of a core material 1 which comprises an organic fiber composition structure of a multi-axis three dimensional woven composition or knitted composition with three or more axes or complex composition of the above. Since the core material 1 made of the organic fiber composition structure has almost same mechanical strength and flexibility of the cartilage, the biomaterial shows biomimetic deformation to function as the artificial cartilage sufficiently. The decomposition rate of the plate 2 which comprises the polymer with in-vivo decomposition absorbability is substantially balanced with the the growth rate of the bone tissue so that the plate is replaced by the bone tissue to connect firmly to the animate bone. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
