Currently many artificial hips and knees have to be replaced because the patient's own bone 'resorbs' and disappears from around the implant. Now; a joint team of researchers from the University of Cambridge, UK, and the Massachusetts Institute of Technology (MIT) in Boston, USA, has started work on developing new and better artificial bone to replace damaged and worn-out human bones. The ultimate goal is to engineer materials that enable the body to regenerate damaged or diseased tissue, such as cartilage in arthritis patients or bone in patients with osteoporosis,' explains Professor Lorna Gibson, Material S Salapatas Professor of Materials Science and Engineering, who is leading the research project at MIT
