The 2023 Hip, Knee and Shoulder Arthroplasty Report is based on the analysis of 1,982,200 (850,603 hip, 1,046,247 knee and 85,350 shoulder) primary and revision procedures recorded by the Registry, with a procedure date up to and including 31 December 2022. As with last year’s Annual Report, to ensure that the relevance and currency of AOANJRR data are maintained, almost all analyses (unless specifically stated) have been confined to hip, knee and shoulder prostheses that were still being used in 2022. Again, historic data are still available in previous Annual Reports on the AOANJRR website. This year, the Registry is again providing an update on the impact of COVID-19 on joint replacement in Australia during 2022 and comparisons to 2020 and 2021, and to the pre-COVID year 2019. In addition to the main report, the Registry continues to publish Supplementary Reports. They include a Lay Summary of the main report and 15 additional reports on arthroplasty topics. The report introduces a special chapter addressing the challenge of infection in joint replacement surgeries, highlighting the steady increase in revision procedures due to infection since data collection began. Each year, the AOANJRR identifies prostheses with higher than anticipated rates of revision. This year, 4 total conventional hip, 3 total knee prostheses and 2 total stemmed reverse shoulder prostheses have been newly identified.
