Joint registry report finds metal-on-metal hip replacements more prone to revision (OrthoSuperSite)
Metal-on-metal hip replacement device failure is still a cause for concern, particularly in women, according to the recently released 2011 National Joint Registry of England and Wales Annual Report.
According to the report, revision rates among hip devices are “by far the highest” in the two main categories of metal-on-metal (MoM) devices —resurfacing devices and those known simply as “metal-on-metal”. Devices in the revision subset carried revision rates of 11.81%, with those in the MoM subset displaying rates as high as 13.61%.
The registry found that non-MoM hip prosthesis types displayed revision rates ranging from 3.31% to 4.94%. According to the release, these figures reflect performance on the registry data at 1-year, 3-year and 5-year intervals up to December 2010.
