California Joint Replacement Registry

About the CJRR

Level 3 RegistryThe California Joint Replacement Registry (CJRR) was created to meet the need for comprehensive, scientific assessment of devices, treatment protocols, surgical approaches, and patient factors influencing the results of hip and knee replacement surgeries.

The CJRR is a Level 3 registry, meaning it collects and incorporates clinical information and direct feedback from patients about the outcomes of their hip and knee replacement surgeries. It is one of only a small number of registries in the United States to do so.

The CJRR’s goals are to:

  • Collect and report scientifically valid data on the results of hip and knee replacements performed in California, including device safety and effectiveness, post-operative complication and revision rates, and patient-reported outcomes; and
  • Promote the use of this information to guide physician and patient decisions and improve the quality of care statewide.

The Value of Registries

Registries are a key tool to collect and provide information which can measure outcomes, support quality improvement initiatives, identify high performing providers, and control costs. Key examples of the uses of registry data are:

  • Providing comparative effectiveness data for and monitor safety of prosthetic devices
  • Reducing complications
  • Reducing revision rates

Joint replacement registries – in Europe, Australia and within U.S. health care organizations such as Kaiser Permanente – have shown that registry activities can improve surgical practices, delivery timely safety alerts and produce better outcomes for patients.

Registries can also save health care dollars. Sweden— a country that performs two-thirds as many hip replacements as California – has credited their Hip Registry with saving the national health system US $140 million in direct costs over a ten-year period. 

Dr. James Caillouette, founding surgeon in chief at the Hoag Orthopedic Institute, describes how the CJRR will improve care by identifying techniques and trends that result in better patient outcomes.

John Koos, a University of California, San Francisco Medical Center bilateral knee replacement patient, shares his motivation for joining the CJRR and the benefits of his participation.
