Problems of biocompatibility from materials in knee arthroplasty

Abstract

In this study, research has been conducted on the formation processes and causes of problems that have arisen over the long term from materials used in knee or hip arthroplasty patients. A rare case has been viewed for a patient who had arthroplasty ten years previously. During a second knee joint revision surgery after implant failure, a biopsy of bone and soft tissue taken from around the implant relevant deterioration caused by the materials used in the initial implant. Using several different technological laboratory methods, analysis of the removed implants and the adhesive materials between bone and implant; besides, the diffusion that occurred between them were examined. In addition, similar problems and research are reviewed in the literature that has been published about the subject. Because problems related to the materials used in knee and hip arthroplasty have arisen, more research is necessary to find appropriate solutions.
