Abstract
An orthopaedic device designed to replace an articulating surface in a joint is provided. The device has a relatively low stiffness factor and is capable of applying normal physiological load onto the underlying bone. A low stiffness factor is achieved by a relatively thin device made from materials that have a low bulk modulus of elasticity. The device is provided with curvature to minimize bending stress in the device so that the device has sufficient mechanical strength to prevent stress induced failure. A tibial component made in accordance with this invention is also provided.
