Comparative Prosthesis Performance: 2024 Supplementary Report

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. This contrasts with the Annual Report Chapter “Ten, Fifteen, and Twenty Year Prosthesis Outcomes” which exclusively analyses modern prostheses only (i.e. prostheses that are still available and still used in 2023). 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 supplementary report provides a historical perspective of prosthesis performance. 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 2023. Individual hip and knee prosthesis combinations with >350 procedures are reported. The Registry is also 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 2023 are identified with an asterisk in each of the tables. The Comparative Prostheses Performance Supplementary Report is one of 14 supplementary reports to complete the AOANJRR Annual Report for 2024. Information on the background, purpose, aims, benefits and governance of the Registry can be found in the Introductory chapter of the 2024 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 2024 Hip, Knee and Shoulder Arthroplasty Annual Report: https://aoanjrr.sahmri.com/annual-reports-2024.
