Some Metal Hip Implants More Likely to Require Early Revision


Patients with large-diameter modular metal-on-metal hip replacements are 1.6 times more likely to require revision surgery within five years than patients with metal-on-plastic implants, according to a new study conducted by the Canadian Institute for Health Information (CIHI). The study was based on nearly 60,000 total hip replacements in Canada reported between 2003 and 2011 and observed the effect of several factors on the risk of patients needing to have their implants replaced within five years of the initial replacement surgery. The study results found patients whose hips were replaced with a metal-on-metal hip were most likely to be males younger than age 55.
