Preoperative identification of a bone-cement allergy in a patient undergoing total knee arthroplasty.

Allergy to polymethyl methacrylate bone-cement or its components is unusual. Because of the potential for an inflammatory response in an allergic patient and the possibility of pain and loosening if a cemented implant is used, it is imperative to identify patients with this allergy to modify their treatment. We report the case of an otherwise healthy 60-year-old woman who needed a total knee arthroplasty and who had an allergy to methyl methacrylate bone-cement identified preoperatively. The appropriate evaluation for a patient who is suspected to have an allergy to bone-cement or its components is reviewed.
