It's beginning to seem like a week doesn't go by without a new story about metal-on-metal hip implants. And this week was no exception. British experts at the world's largest artificial joint registry recommended this week that doctors cease use of metal-on-metal (MoM) hip implants. Basing their recommendation on a recent study, the experts found that after five years, approximately 6% of MoM hip implant patients required revision surgery compared with 1.7 to 2.3% of patients with ceramic or plastic implants. On this heels of this news, Smith & Nephew announced that a study of its MoM implants yielded positive results. Read about these and more top stories of the week in the roundup below.
