title: [Characterization of the biological process of aseptic loosening of joint implants in orthopedics].
abstract: The purpose of orthopedic joint implants is to improve joint movement. Within the past 30 years, biomechanical improvements affecting the life-span of the implants has brought a new type of problem: the biological response to debris from the implant material contributes greatly to aseptic loosening of the prosthesis. The process is mediated by osteotropic factors, cytokines released from mononuclear cells, and osteoblasts and osteoclasts in the bone-cement interface or bone-implant interface.
