For the study, researchers compared the incidence of new cancer diagnoses for more than 40,000 patients with metal-on-metal hip implants to patients with different bearing surfaces and the general population.
The analysis showed that cancer diagnoses were lower for patients with metal-on-metal hip replacements five years after surgery than patients with hip replacements using other bearing surfaces.
The research is telling in light of ongoing litigation regarding DePuy’s recalled hip implants. The device, which was made from a cobalt and chromium alloy, released metal debris into patients’ bodies and caused adverse outcomes such as tissue death and increased metal ions in the bloodstream.
