UK – Are Smaller Hip Implants in Older Patients More Cost Effective?

University of Bristol Medical School Researchers led a study that shows cemented metal-on-plastic hip replacements less than 36 mm in diameter are the most cost-effective in patients older than 65.

A study by researchers at the University of Bristol Medical School has shown that small-head cemented metal-on-plastic hip replacements less than 36 mm in diameter are the most cost-effective in patients older than 65.

The research was led by the Hip Implant Prosthesis Study (HIPS) team and found no evidence that uncemented or hybrid hip replacements are cost-effective options, while large-head implant sizes more than 36 mm in diameters are also not cost-effective.

To reach their conclusion the researchers used data from two large national cohorts, the National Joint Registry for England, Wales, and Northern Ireland, along with the Swedish Hip Arthroplasty Register. More than one million patients with total hip placement were analyzed…
