We examined samples of tissue and components that had been removed during
twenty revisions of total hip arthroplasties in which a titanium-alloy
femoral component had been used. Minute amounts of metallic debris were
detected in the tissues from two patients. The amounts of polyethylene and
methylmethacrylate debris and the histological reactions in the tissues
corresponded closely with those reported in earlier studies of total hip
prostheses made of stainless steel or cobalt-chromium alloy.
