• The ACORN is a multicentre registry that aims to improve the quality and effectiveness of joint replacement surgery by monitoring and evaluating patient reported clinical outcomes after surgery.
  • The registry will enable improvements in care by:
  • * Identifying characteristics and co-morbidities that place people at risk of poor outcome after joint replacement
  • * Monitoring rates of key complications, such as VTE and infection, that require management, reoperation or hospital readmission
  • * Providing a better understanding of the relationship between co-morbidities and other potential risk factors, and outcomes
  • * Identify high performing sites and investigate reasons for superior outcomes
  • * Identify and investigate variation in patient-reported outcomes to improve understanding of differences
  • * Use data to improve the quality of arthroplasty surgery
