A group of medical researchers and scientists have determined that the potential risks from metal-on-metal hip implants may outweigh any health benefits provided by these devices.
This is because of higher revision rates are linked to the newer hip replacement designs and the mounting and growing concerns about metal ion blood poisoning, known as metallosis.
The California Technology Assessment Forum (CTAF) has released an assessment of the benefits and effectiveness of using metal on metal hip replacements as an alternative to total hip arthroplasty, and they concluded that the relatively new metal hip implants may not be worth the risk.
