Total Joint Replacement

Three decades of research have consistently demonstrated that patients who have their high-risk surgery performed at a hospital and by a surgeon that have more experience with the procedure have better outcomes, including lower mortality rates, lower complication rates, and a shorter length of stay, than patients who have their surgery done at a hospital or by a surgeon with less experience.

Based on the research by Dartmouth-Hitchcock Medical Center, Michigan Medicine, and Johns Hopkins Medicine, as well as guidance from Leapfrog’s national expert panel, Leapfrog has identified two total joint replacement procedures for which there is a strong volume-outcome relationship.

The procedures with their corresponding minimum hospital volumes and minimum annual surgeon volumes for privileging are shown in the table below.

Procedure Minimum hospital volume standard Minimum annual surgeon volume standard
Total knee replacement surgery 50 25
Total hip replacement surgery 50 25
