Approximately 500 000 total knee artroplasty (TKA) procedures are performed in the US annually. Using large, population-based databases, these authors demonstrated that TKA was associated with a modest increase in lifetime costs but with a large increase in quality-adjusted life years, making it a highly cost-effective procedure. TKA performed in high-volume hospital centers conferred even greater value per dollar spent.
