Research papers

The NJR encourages use of the registry dataset to answer research questions that add value to our knowledge about joint surgery practice, clinical performance, value for money and patient safety. Researchers use the data to analyse questions about outcomes in relation to particular underlying disease and patient comorbidity, as well as examine clinical outcomes related to the implant prosthesis used. Over the last 12 months, 15 papers have been published using NJR data, covering a broad range of topics across all of the joints.

The papers below which have all been published illustrate the broad range of topic opportunities for external researchers to access and analyse the NJR dataset.

Each of them demonstrates the value of the use of these collected data to the orthopaedic community to ultimately improve patient outcomes.
