Abstract: A method of using an orthopedic implant includes providing a main body, as well as a porous augment having a bone ingrowth surface. The main body is removably attached with another surface of the porous augment to form an orthopedic implant.

Abstract: The present invention provides an orthopaedic implant including a base device having a device surface and a fixation material attached to at least one portion of the device surface. The fixation material is configured to provide a minimally sufficient adhesive force to resist natural pull out caused by forces acting on the base device after implantation and bone growth. Also provided is a method of manufacturing an orthopaedic implant. A base device with a device surface is provided and a minimally sufficient adhesive force, that can resist natural pull out caused by forces acting on the base device after implantation and bone growth, is determined. A proper amount of fixation material sufficient to provide an adhesive force equal to the minimally sufficient adhesive force is determined and fixation material is applied to the device. When the proper amount of fixation material is applied to the device surface, application is stopped.
