Another metal-on-metal hip replacement is being withdrawn from the market. While this is not a formal recall, the manufacturer, was apparently concerned about the use of this implant, and decided to pull it from the market.
Metal-on-metal hip replacements have been questioned over recent months. A highly publicized recall of an implant manufactured by the DePuy division of Johnson & Johnson has caused significant anxiety for hip replacement patients and caused concern about they way medical implants are approved for use.
The concern about metal-on-metal hip replacements is that while they were designed to last longer than metal and plastic implants, the data often shows they don't last as long, and may cause more problems. Surgeons are becoming increasingly way of implant metal-on-metal hips.
