OrthoStreamers… sharing the UK Joint Registry 2003-2019 with you


The interactive portion of the NJR’s 17th Annual Report can be found online via the registry’s dedicated NJR Reports website at: reports.njrcentre.org.uk.

Here we present data on clinical activity during the 2019 calendar year. This includes information on the volumes and surgical techniques in relation to procedures submitted to the NJR, with the most recent data being for the period 1 January 2019 to 31 December 2019. To be included in these tables and graphs, all procedures must have been entered into the NJR by 29 February 2020.

The double page infographic spread at the end of this report offers a visual summary of key facts relating to the analysis of clinical activity during the 2019 calendar year. This can also be downloaded as a waiting room poster via reports.njrcentre.org.uk/downloads.
