Abstract
The disclosure relates to a tissue and debris barrier for use in association with implanted joint replacement devices. The barrier comprises a biocompatible membrane that is impermeable to debris. The membrane defines an aperture which is positioned about a component of the joint replacement prosthesis. The periphery of the membrane may be mechanically attached by suturing to adjacent tissue or may be provided with areas of selected porosity to promote tissue adherence. The barrier permits full motion of the replacement joint while preventing or impeding tissue and debris from migrating to and from bone implant interfaces.
