Artificial Hips: Newer Might Not Be Better

  Traditional hip implants might be safer and last longer than some new ones, an FDA-funded study finds.

It’s among the first studies to compare outcomes in people who got different kinds of artificial hip implants with different materials.

When researchers evaluated total hip-replacement data from studies and national registries, they found no advantage for the newer metal-on-metal or ceramic-on-ceramic devices, compared with traditional metal-on-polyethylene or ceramic-on-polyethylene ones.

The available evidence suggests that traditional hip replacement devices work as well as newer, costlier implants and might last longer than at least some newer artificial hips.

The researchers conclude that manufacturers of the newer implants cannot claim that their devices are better than traditional ones.

But others feel that more research is needed to draw any strong conclusions.

Hip Replacement Devices are All the Same, Study Says | ThirdAge

  Hip replacement implants all work the same regardless of the material used, according to a new study.

The newer, metal-on-metal implants appear to be no more effective than older implants and may sometimes even be more problematic, the researchers said, according to HealthDay News.

“Metal-on-metal and ceramic-on-ceramic hip implants might not be associated with any advantage, compared with traditional bearings such as metal-on-polyethylene or ceramic-on-polyethylene,” lead researcher Dr. Art Sedrakyan, director of the Patient-Centered Comparative Effectiveness Program at Weill Cornell Medical College in New York City, told HealthDay.

While there is some evidence from three large national registries that higher rates of replacement surgery are associated with metal-on-metal implants, compared with metal-on-polyethylene implants, there is simply not enough information about these implants to determine if one type is better or safer than the other, Sedrakyan continued. Even for newer implants such as metal-on-metal or ceramic-on-ceramic bearings, their advantage over traditional implants is not clear, he told HealthDay.
