MEMBER FOR REGENERATING JOINT CARTILAGE AND PROCESS FOR PRODUCING THE SAME, METHOD OF REGENERATING JOINT CARTILAGE AND ARITFICIAL CARTILAGE FOR TRANSPLANTATION

摘要

It is intended to provide a member for regenerating a joint cartilage which can be integrated with the existing surrounding cartilage joints in a favorable state under natural conditions as much as possible so that a joint cartilage having the original thickness can be quickly regenerated, and a process for producing the same. It is also intended to provide a method of regenerating a joint cartilage either in vivo or in vitro, a method of culturing the same, and an artificial joint cartilage for transplantation obtained by these methods. A joint cartilage is regenerated/cultured using a member for regenerating a joint cartilage made of a porous hydroxyapatite material wherein pores are three-dimensionally connected to each other via openings, the porosity ranges from 50% to 90% and the average pore size ranges from 100 μm to 600 μm.
