Costs and Outcomes After Primary and Revision Hip Replacements by Implant Bearing Materials: Analysis of 550 760 linked Patient Records from English Routinely Collected Databases

Revision surgery costs double than that of an elective primary with drastically lower quality of life.

Although observational data may be affected by unmeasured confounding, our findings could help guide procurement decisions given changing trends in implant choice.
