    摘要: An object of the present invention is to provide a biomaterial for an artificial cartilage that eliminates the risk of possible adverse effects due to scattering of fragments of the biodegradable and bioabsorbable polymers and is joined further solidly to vertebral bodies and the like with increased adhesiveness.
    The biomaterial for an artificial cartilage according to the present invention includes: an organized structure comprising organic fibers arranged in one of a multiaxial three-dimensional woven or knitted structure having three or more axes and a combined structure of the woven structure and the knitted structure; and a biodegradable and bioabsorbable pin provided inside the organized structure, two ends of the pin becoming projected from upper and lower surfaces of the organized structure upon compression on the organized structure from above and below, each of the upper and lower surfaces or either one of the surfaces of the organized structure having a superficial portion of a soft layer that is softer than the other portion of the organized structure, part or all of the organic fibers of the superficial portion being coated with a biodegradable and bioabsorbable polymer complex containing bioactive bioceramic powder. Adhesiveness with vertebral bodies and the like is increased by making the superficial portion(s) of the organized structure as a soft layer, the scattering of the polymers is prevented by coating the organic fibers of the superficial portion with the above complex, and the solid joint to vertebral bodies and the like is achieved.
