Cobalt poisoning in knee replacements - Caring Medical
The results clearly show that the metal-on-metal hinge knee replacement carries a high risk of increased levels of systemic metal ions and also local adverse patient reactions to metal debris, leading to complicated knee revisions. We, therefore, discourage the use of metal-on-metal hinge knee replacements. 1. And if you are sensitive to cobalt ...
