In The Bleeding Edge, Dr. Tower wonders if some elderly patients – the ones most likely to need a hip transplant – might have been wrongfully diagnosed with a form of dementia, when in fact they were showing signs of a reversible condition, instead. The biggest culprit for toxicity seems to be cobalt-chrome but there is no generally accepted threshold beyond which serum or blood concentrations of cobalt and chromium are known to be toxic8. Secondary diag-noses, such as Alzheimer’s disease, are rarely tracked in total joint replacement research because of the limited accessi-bility of outside patient records. The biggest culprit for toxicity seems to be cobalt-chrome but there is no generally accepted threshold beyond which serum or blood concentrations of cobalt and chromium are known to be toxic8. Over 600,000 people undergo knee replacement surgery every year in the United States. For the study, a team ran cognitive and brain-imaging tests before and after surgery on four dozen patients ages 60 and older undergoing a knee replacement.
