3-D printing could one day help fix damaged cartilage in knees, noses and ears

Athletes, the elderly and others who suffer from injuries and arthritis can lose cartilage and experience a lot of pain. Researchers are now reporting, however, that they have found a way to produce cartilage tissue by 3-D bioprinting an ink containing human cells, and they have successfully tested it in an in vivo mouse model.
