This document reports the numbers of prostheses recorded and reported to the NJR between 1 January and 31 December 2020. The tables show volumes of components as they have been entered into the registry, regardless of construct.
The procedure counts in this document are presented without adjustment and may vary from counts found in the corresponding main NJR Annual Report analysis. If a procedure has been submitted with missing implant information this will also cause numbers to differ. Procedure counts below four have been suppressed.
Components are listed and described according to the current classifications used in the registry.
It must be noted that due to COVID-19, the ratio of revision to primary procedures increased in 2020 and this may affect the relative changes in the types and brands of implants used in comparison to previous years. As this document was not published for 2019 Annual Report data, comparison has been made with the 2018 Annual Report data.
