Cost-effectiveness analysis of implants used in total hip replacements

Editor's Note

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 (less than 36 mm in diameter) cemented metal-on-polyethylene implants were the most cost-effective for adults older than 65 years.
• 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.
