Abstract

An osteochondral scaffold has a chondrogenic spiral scaffold in one end of an outer shell made of sintered microspheres, and an osteogenic spiral scaffold in the other end of the outer shell. Each spiral scaffold has nanofibers of a composition selected to promote attachment and proliferation of the desired types of cells. The nanofibers for the chondrogenic spiral scaffold have a different composition than the nanofibers for the osteogenic spiral scaffold. The nanofibers of each spiral scaffold are aligned to orient the attached cells so as to recreate the structure of the native tissue.
