Mäkelä K. Acta Orthop. 2014 Original Article Available by Clicking Here The use of metal-on-metal total hip arthroplasty implants was not linked to a higher risk of cancer in patients compared to the use of non-metal-on-metal devices… …Using information from the Finnish Arthroplasty Register, the researchers compared 10,728 patients with metal-on-metal (MoM) hip implants to 18,235 patients who received non-MoM hip implants during procedures performed between 2001 and 2010… …The researchers found the cancer risk was not higher in the MoM patients compared to non-MoM patients; however, the risk of soft-tissue sarcoma and basalioma was higher in the metal-on-metal cohort. Overall, the risk of death was lower in MoM group compared to the non-MoM group.
