Abstract
One embodiment of the present invention is directed to compositions and methods for enhancing attachment of soft tissues to a metal prosthetic device. In one embodiment a construct is provided comprising a metal implant having a porous metal region, wherein said porous region exhibits a nano-textured surface, and a biocompatible polymer matrix coating the nano-textured surface. The polymer matrix coating comprises a naturally occurring extracellular matrix with biocompatible inorganic materials distributed within the matrix, or a biocompatible polymer and an osteoinductive agent.
