A process of forming a prosthetic implant component, such as the femoral component of a knee replacement prosthesis. The process comprises the steps of: (i) forming a prosthetic component having a shape at least approximating the desired final shape of the component from a metal alloy； (ii) subjecting the component to a relatively elevated temperature and pressure followed by a cooling regime； (iii) machining the surface of the component； (iv) polishing the surface of the component.
