This page provides links to all the information about metal-on-metal hip implants for patients, healthcare professionals and the media.

The majority of patients implanted with metal-on-metal hip replacements have well functioning hips and are thought to be at a low risk of developing problems. Metal on metal resurfacing hip implants enable young patients to lead pain free, independent lives

However, a small number of patients with large metal on metal full hip replacements could develop complications.

That’s why on 28 February 2012 we issued updated patient management and monitoring advice to surgeons and doctors that they should monitor patients every year for the lifetime of their metal on metal total hip replacements sized 36 millimeters or more.

By monitoring patients every year, any complications will be picked up earlier and more complex surgery on the patient can be avoided.

The MHRA was the first regulatory agency in the world to issue advice to clinicians about metal on metal hip implants in April 2010. An expert advisory group that includes orthopaedic surgeons was set up in 2008 by the MHRA to look at the management of patients with soft tissue swelling associated with metal on metal hip implants. This group meets regularly to evaluate new scientific advice and observations from clinicians.
