摘要：
The present invention provides a bone in-growth surface for implants which has a structure for delivering therapeutic agents to surrounding bone and tissue. The bone in-growth surface may comprise scaffolding and a controlled-permeability layer which contains the therapeutic agents in a variety of reservoirs. The porosity of the scaffolding may be controllable from zero porosity to essentially a fully porous material.
