Abstract
A method of fitting orthopaedic prostheses is disclosed in which a semi-permeable microporous membrane is fitted over an implanted prosthesis so as to cover the junction between the prosthesis and the bone. In this way, particles generated by mechanical wear of the prosthesis are excluded. Such particles are believed to inhibit bone regeneration in the region of the prosthesis. In addition, by preventing the ingress of fibrous connective tissue cells, a secondary seal of new bone will form between the membrane and the original bone.
