Beta Titanium is the only known material that matches the modulus of elasticity of bone that is perfect for application in hip, shoulder and knee replacement. However, the only problem is that no one is currently manufacturing replacement joints that are made of beta titanium. The most commonly used today is metal joints. Using metal joints is risky as their mechanical properties do not match the modulus of elasticity of bone. As a result, the bones will likely break or waste away, often leading to amputation. Most orthopaedic surgeons are well aware of these issues and are seeking for substitutes of metal joints.
