The purpose of this supplementary report is to ensure that the Registry provides updated 10, 15 and 20 year data on the comparative performance of all prostheses including those that are no longer used. Analyses presented in the main report are now limited to prostheses that were still used in 2022. Surgeons at the Annual Report Workshop highlighted that there was ongoing interest in the comparative performance of all devices reported to the Registry and recommended its inclusion as a supplementary report. This report presents comparative performance information on hip and knee prostheses used for the treatment of osteoarthritis for the three different time periods irrespective of their use in 2022. Individual hip and knee prosthesis combinations with >350 procedures are reported. For the first time, the Registry is reporting 10 year outcomes for primary total shoulder replacements. Individual humeral and glenoid prosthesis combinations are reported. A combination is included if >50 procedures have been reported to the Registry and the follow-up is ≥10 years. Those prostheses not used in 2022 are identified with an asterisk in each of the tables. To identify superiority and non-inferiority, the new benchmark standards described in the main report are used. These standards are based on the aggregate performance of devices in a class still being used in 2022. A prosthesis combination is identified as having a superiority benchmark if the upper confidence interval is less than, or equal to, the benchmark standard. These devices are highlighted in green in the relevant tables. A prosthesis combination is identified as having a non-inferiority benchmark if the upper confidence interval level is not more than 20% above the benchmark standard. These devices are highlighted in blue in the relevant tables. The Comparative Prostheses Performance Supplementary Report is one of 16 supplementary reports to complete the AOANJRR Annual Report for 2023. Information on the background, purpose, aims, benefits and governance of the Registry can be found in the Introductory chapter of the 2023 Hip, Knee and Shoulder Arthroplasty Annual Report. The Registry data quality processes including data collection, validation and outcomes assessment, are provided in detail in the Data Quality section of the introductory chapter of the 2023 Hip, Knee and Shoulder Arthroplasty Annual Report: https://aoanjrr.sahmri.com/annual-reports-2023.
