This supplementary report provides information on the use of cement in primary total hip and primary total knee replacement. The trends in use over time and the revision rates for antibiotic cement and plain cement are provided. The use of antibiotic cement has increased over time. In 2023, 99.6% of cemented total conventional hip replacements and 99.6% of cemented total knee replacements used antibiotic cement. In primary total conventional hip replacement, antibiotic cement has a higher rate of revision in the first 6 months and a lower rate after this time compared to plain cement. When revision for infection is analysed, antibiotic cement has a higher rate of revision in the first 3 months and a lower rate of revision for infection after this time compared to plain cement. In primary total knee replacement, antibiotic cement has a lower rate of revision compared to plain cement. However, this may be confounded by multiple factors and there is no difference in the rate of revision for infection. This 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.
