Welcome from the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man


Hip, knee, ankle, elbow and shoulder joint replacements are common and highly successful operations that bring many patients relief from pain and improved mobility. Thousands of these joint replacement operations take place in the UK every year.

The National Joint Registry (NJR) was set up by the Department of Health and Welsh Government in 2002 to collect information on all hip, knee, ankle, elbow and shoulder replacement operations, to monitor the performance of joint replacement implants and the effectiveness of different types of surgery, improving clinical standards and benefiting patients, clinicians and the orthopaedic sector as a whole. Northern Ireland joined in 2013 and the Isle of Man in 2015.


Latest NJR News:


A joint statement from the NJR Implant Scrutiny Committee and the
Executive Council of the British Elbow and Shoulder Society (BESS) on the
definition of revision joint replacement.
The NJR have recently updated the MDS forms for primary and revision shoulder
and elbow replacements. This was after input and collaboration with BESS Council
and the BESS Arthroplasty Working Groups.
During that process it became clear that revision surgery means any further
operation on a patients joint replacement to remove, change or reduce any of the
components. It has been suggested by some stakeholders that some shoulder
arthroplasty procedures should be considered a ‘conversion’ rather than a
The failure of a replaced shoulder or elbow joint is usually multifactorial and can
be a complex interaction of patient, implant and surgical factors. Conversion
implies that the implant construct is blameless in any failure mechanism and this
can be misleading. Therefore in relation to shoulder and elbow replacement
surgery, BESS and the NJR Implant Scrutiny Group will continue to consider a
revision as any further operation to remove, change, add or reduce any of the
components, and such procedures will be recorded thus on the new MDS forms.
