New research from the Hip Implant Prosthesis Study (HIPS) team at the University of Bristol Medical School that analyzed hip replacements in more than 1 million patients in the United Kingdom and Sweden found that:

  • Small-head cemented ceramic-on-polyethylene implants were the most cost-effective for adults younger than 65 years.

There was no evidence that uncemented, hybrid, or reverse hybrid implants were the most cost-effective, and large-head (more than 36 mm) implants were not cost-effective.

The findings can influence clinical practice and procurement decisions for payers worldwide, the researchers say.
