A Clinical Practicum

Over a million metal-on-metal hip prostheses have been implanted since 1996, according to the Hip Society [1]. Controversy arose with reports of adverse tissue reactions and increased rates of revision associated with some of the implant designs during the 2000s. Today (2013), while many orthopaedists have discontinued using metal-on-metal implants, others continue to implant prostheses with this hard-on- hard bearing.
