2. Present conditions of artificial joint ( 2013 )
Basic conditions necessary to materials for artificial joint are as follows.
① Exellent suitabilities for living body
② Sufficient dynamical strength
③ Excellent abrasion-resistant properties ( durabilities against abrasion )
④ Which are chemically stable without deteriorations of materials
Though artificial joints to satisfy above respective conditions are desired, actual situations have been still insufficient for such requirements.
