The goals of the Registry are to: (a) 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 assessments; and (b) promote the use of performance information regarding hip and knee replacements to guide physician and patient decisions and support programs for provider recognition and reward, and thereby encourage quality and cost improvements through marketplace mechanisms. Specifically the registry is designed to:

  • Compile reports assessing the outcomes associated with different devices and surgical techniques.
  • Create confidential benchmarking reports for physicians and hospitals that detail each provider's performance data and compare it to statewide averages.
  • Transmit safety alerts on devices with short-term results that provoke concern.
  • Shape a measurement and reporting system for orthopedic procedures.
  • Provide patients with useful information about outcomes after surgery to help them make decisions about their care.
