Yogendra Pratap Singh from IIT Guwahati explains how the biphasic scaffold fabricated using silk is superior to the existing ones. Since the entire scaffold is made of silk, the junction between the half that is spongy and mimics the cartilage while the other half is less porous and mimics the bone is seamless. In rabbits, the fibre-reinforced scaffold allowed more bone formation, while the cartilage was regenerated and completely repaired.
