This article, published in the March 13, 2012 edition, recommends against using metal-on-metal implants in all situations. Furthermore, authors suggest patients who already have these implants should be monitored carefully, paying special attention to implants with large diameter heads in young women.
The study found that implants with larger heads fail earlier than those with smaller heads. The study found five-year revision rates for young women were 6.1 percent, compared with 1.6 percent when surgeons used metal-on-polyethylene implants.
Ceramic-on-ceramic articulations with larger heads were associated with improved survival rates.
