Research progress on wear particles and periprosthetic osteolysis after artificial joint replacement

Abstract

It is an important influencing factor that the generated wear particles lead to periprosthetic osteolysis after artificial joint replacement. Current research suggests that the primary cause of wear particles results in periprosthetic osteolysis is relate to the prosthetic materials and the stimulations because of these materials generated wear particles to relevant cells such as macrophage, osteoblast, osteoclast. Induced a variety of inflammatory cytokines, activating and openning the cell signal and channels, producing the long term chronic inflammation leads to periprosthetic osteolysis. Therefor, the paper mainly studies the different types of wear particles influence on periprosthetic osteolysis, and the wear particles around the periprosthetic osteolysis mechanism in the process of progress, moreover, to explore how to reduce the occurrence of wear particles and blocking its role in the periprosthetic osteolysis, in order to achieve the purpose of prevention and treatment of periprosthetic osteolysis.
