NJR Research publications and outputs

The NJR encourages the use of the registry dataset to answer research questions that add value to our knowledge about joint replacement practice, clinical performance, cost-effectiveness and patient safety.
Researchers effectively use the data to analyse questions about outcomes in relation to particular underlying disease and patient comorbidity, as well as address clinical and cost-effectiveness outcomes related to the implant prosthesis used.

On this page, we provide details of papers that have been recently published which illustrate the opportunities for external researchers to access the NJR dataset to ask questions not only about joint replacement outcomes, but also to test and validate novel analysis methodologies. Each of them demonstrates the value of the use of this collected data to the orthopaedic community to ultimately improve patient outcomes.
Further details of these and other research publications using NJR data can be found below and in Appendix 4 at reports.njrcentre.org.uk/downloads.
