The Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) is an initiative of the Australian Orthopaedic Association (AOA). The AOANJRR was established in 1999 becoming fully national in mid 2002. The purpose of the AOANJRR is to improve and maintain the quality of care for individuals receiving joint replacement surgery. Information on hip, knee, shoulder, elbow, wrist, ankle and spinal disc replacement is collected from all hospitals in Australia undertaking joint replacement surgery.

The Commonwealth of Australia has declared the AOANJRR a Federal Quality Assurance Activity under part VC of the Health Insurance Act, 1973.

The AOANJRR is funded by the Commonwealth Department of Health.

2021 Annual and Supplementary Reports

It is a pleasure to present the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) Annual Report for 2021. This important document reflects the Australian Orthopaedic Association's (AOA) commitment to ongoing improvement in orthopaedic care. A critically important prerequisite to achieve this is the provision of quality data that can be used to inform beneficial change. Encouraged by the membership, the AOA established the AOANJRR over 20 years ago for this very purpose. This is the Registry's 22nd Annual Report.

The AOANJRR's core activity is the routine collection, analysis, and reporting of procedure data on the ever-increasing number of joint replacements undertaken each year in Australia. The Annual Report which currently has over 30,000 downloads per year provides an up-to-date overview of current practice and results. This information has changed practice and improved outcomes not only in Australia but also internationally.

Previously reported analyses on the outcome of primary hip, knee and shoulder replacement have been updated and extended. This year's report involved the analysis of 1,723,466 primary and revision procedures (743,899 hips, 911,953 knees and 67,614 shoulders). This is the total number of hip, knee and shoulder replacement operations recorded by the Registry with a procedure date up to and including 31 December 2020. Some of the prosthesis designs reported since the Registry first began collecting data in 1999 are now no longer used. Understandably, the performance of many of these older designs is not quite at the same standard as the currently used prostheses (described as ‘modern prostheses’). To ensure that the relevance and currency of AOANJRR data are maintained, almost all analyses (unless specifically stated) have been limited in this year's report to modern hip, knee and shoulder prostheses i.e. those prostheses that were still being used in 2020. As with previous annual reports, a number of new topics have been selected for more detailed analysis.

There are two new chapters in the report this year. The first reports the impact of COVID-19 on joint replacement surgery. The second chapter reports the outcomes of patient reported outcome measures (PROMs). This is the first time the Registry has reported this data.

As in previous years, in addition to the main report, the Registry is also publishing supplementary reports. They include a Lay Summary of the main report, 14 different reports on arthroplasty topics, as well as detailed analyses of all prostheses identified as having a higher than anticipated rate of revision.

It is important to acknowledge that this has not been an easy year. Health systems have been under strain and the capacity to provide routine health care has been stretched. During this difficult time, AOANJRR staff and staff at SAHMRI and UniSA have continued to work tirelessly to maintain Registry activities and develop and implement improvement strategies. Without the support of all involved, the work of the Registry would not be possible.
