Metal-on-metal (MOM) hip implants have had a rough go lately. In the last few years, this market has been largely decimated due to a number of complaints of implant failure and complications. Now, in January 2013, the industry was dealt another blow as the FDA requested that all manufacturers selling MOM hip implants go through a lengthy, expensive, PMA process?even those already selling these products. The FDA also made some recommendations regarding the ideal patient type?with the conclusion being that these implants are best in young males with large femoral heads?and suggested follow-up monitoring every 6 months if a patient is symptomatic. Additionally, J&J has been facing some negative press because it recently came to light that the company has been aware of the high failure rate of its recalled ASR MOM hip implants since 2011.
