© 2017 Elsevier Ltd One of the greatest technological advances in the history of medicine is the total joint replacement. Hip, knee, and shoulder replacements are routine throughout the world. They reduce pain in a cost-effective way and improve quality of life for millions of patients with end stage arthritis. Total hip replacement (THR) is considered a landmark surgery in modern medical history. The THR has developed with research and experimentation over the last 40–50 years with progressive improvement in materials used, fixation techniques, and peri-operative care. With improving life expectancy and increasing demand at a younger age, clinicians and scientists are always trying to find better performing implants to reduce the revision burden. This paper provides an up-to-date account of the relevant history of metal-on-metal (MoM) hips, problems associated with their use, current status, and guidance about how to continue surveillance of patients with MoM hip replacements.
