11.  I have a metal allergy, can I have a hip resurfacing
Dr. Bose:
Allergy after artificial joints is an interesting issue. One must keep in mind that the co-cr-mo alloy has been in clinical use for 45 yrs and is present in 99% of all hip and knee replacement surgery. Even if a component is titanium the articulating part would be always co-cr-mo. Therefore metal sensitivity is not exclusive to metal on metal joints. It is a factor in every joint replacement surgery and therefore has been used in millions of patients. Skin allergy is quite different from deep tissue allergy which is mediated by different mechanisms of immune response by the body. Thus skin testing is of no value when trying to gauge deep tissue hypersensitivity. There have been reports of hundreds of patients who had skin sensitivity but went on to have very successful resurfacing. Only one thing can be said about deep tissue sensitivity at this point in time—it is very very rare.
