Polyethylene particles of a ‘critical size’ are necessary for the induction of cytokines by macrophages in vitro

Particulate wear debris from total hip prosthetic components can stimulate macrophages to produce mediators of osteolysis which may cause aseptic implant loosening. This study evaluated the in vitro response of murine peritoneal macrophages to polyethylene particles of difinitive size distributions...
