Welcome to the National Joint Registry (NJR)
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 and the NJR collects and monitors information on these joint replacement operations to improve clinical standards and benefit patients, clinicians and the orthopaedic sector as a whole.
The NJR was set up by the Department of Health and Welsh Government in 2002 to provide an early warning of issues relating to patient safety, improve the quality of outcomes and ensure the quality and cost-effectiveness of joint replacement surgery. Northern Ireland joined in 2013, the Isle of Man in 2015 and the States of Guernsey in 2019.
We welcome applications for the position of Chair - National Joint Registry Steering Committee (NJRSC)
As Chair of the NJRSC, the successful appointee will lead and engage fully in collective consideration of NJR issues, taking account of the full range of relevant factors and stakeholder interests, help contribute to the advice given to NHSE/I and key stakeholders and participate in and monitor the work of the NJR sub-committees and other relevant committees as required.
Potential candidates will bring experience of leading an organisation at Board and/or national level, with the ability to motivate and empower a committee and with very well-developed communication and stakeholder engagement skills. This experience will most likely have been gained in an NHS or healthcare-related environment and with an understanding of the political environment in which the NJR operates.
Applications are open until Wednesday 19 January 2022

Improving the NJR’s data management processes
Now with over 3.2 million records, our data collection and analysis work provides evidence to drive the continuous development and implementation of measures to ensure implant safety is always top of the agenda. The purpose of this work is also to enhance patient outcomes and reduce revision rates year-on-year, to improve standards in quality of care and to address overall cost-effectiveness in joint replacement surgery. NJR collects data from NHS and independent sector hospitals across England, Wales, Northern Ireland, the Isle of Man and the States of Guernsey.
You can read more how we do this here where you will also find flow diagrams that explain how registry data flows and how data is cleaned for our annual report. We are currently undertaking further improvement work to streamline the way that we collect, analyse and report NJR data and further improve the accuracy, consistency and transparency of our work.
NJR Surgeon and Hospital Outcomes Publication 2020/21
The outcome results FY2020/21 will be published in on the NJR Surgeon and hospital website on 19th January 2022. All consultant orthopaedic surgeons in England, Wales, Northern Ireland, the Isle of Man and the States of Guernsey, who have carried out at least one hip/knee/ankle/elbow/shoulder joint replacement procedure as ‘Consultant in Charge’ in any hospital in the above regions during the most recent three financial years from 1st April 2018 to 31st March 2021, will be included for publication.

NJR 18th Annual Report launched at BOA Congress:
The NJR Annual Report 2021 was launched at the BOA Annual Congress this week and can be found here. You can download the PDF and also view all online parts on the report including an overview of this year’s work developments and activities as well as reports from all of our sub-committees and a special feature on COVID-19.
This, our 18th Annual Report, was launched during the NJR’s presentation session at Congress, where the authors of the report's special feature addressed the impact of COVID-19 on last year's surgical procedure volumes, alongside a moving presentation on the patient perspective of what it is like to be on a long waiting list especially when combined with the ongoing uncertainty of treatment timelines.
All our speaker presentations this year followed the Congress theme of ‘Tackling Infection’.
We also had a lot of interest in the NJR’s information stand at the event which delegates visited to download a QR code to give them direct access to the new annual report online and to see our featured research topic information. Visitors were also able to find out more about the developments to upgrade NJR clinical reporting services with a video demonstration of the functionality of our new portal NJR Connect - Data Services and to meet with our Compliance Officers on the stand, who were there to support surgeons’ visits to the new site.
All in all it was excellent to be back out at event like the BOA Congress at last - and to see so many familiar faces!

New NJR Implant Scanning Interface
The NJR has recently developed a mobile / tablet friendly responsive website interface which provides an ‘front end’ that enables details of component lists to be scanned with a bar code scanner, mobile phone or tablet, and the results or flag concerning the combination are returned directly to the user.
The advantage of this interface is that users are able to access the implant validation function without the need for development of other third-party IT systems. This independence from third-party systems is beneficial when a hospital does not have the Scan4Safety system, or access to IT system development resources. You can find further details here https://www.njrcentre.org.uk/njrcentre/Healthcare-providers/NJR-Implant-Scanning-Tool
This option is offered free of charge to all hospitals that undertake orthopaedic joint replacements in England, Wales, Northern Ireland, the Isle of Man and the States of Guernsey.
Please contact us at: email@example.com should you wish to make an enquiry regarding either interface.
Consultant Level Report (CLR) and Surgeon Level Report (SLR)
This year's CLRs and SLRs have been available to download at the new NJR Connect - Data Services platform since 20th July. There are many changes to the reports this year click here for more information on this. You can find information on how to access your reports here.
Understanding ODEP / NJR data in your report
ODEP and the NJR work closely together in order to collect and monitor joint replacement data in the UK and the data in the NJR Consultant Level Reports (CLRs) are courtesy of both organisations. There are some important points that you shouldn’t overlook, particularly as this year the data you are receiving are more comprehensive.

Data entry capture resumed for the National Joint Registry
Following NHSE wider notification to hospitals of the resumption of elective surgery and associated audit activity, in order to support NHS recovery as the COVID-19 pandemic lessens, the National Joint Registry advises data entry staff in all NHS and independent hospitals where joint surgery has resumed, that data entry capture should also resume as normal, in accordance with the volumes of procedures performed.
It is also important that the reduced volumes of arthroplasty procedures that have taken place over the COVID-19 height of the pandemic period are correctly recorded on the NJR. These are likely to be small numbers of urgent and emergency procedures, but it is essential that we are able to monitor the outcomes of these patients through the NJR’s usual monitoring procedures. We therefore ask that hospitals review their surgical caseload over this period to ensure that any missed cases are entered retrospectively onto the NJR.
For any advice and support on NJR data entry or training: please contact our Helpdesk on 0845 345 9991 or by email firstname.lastname@example.org
NJR Regional Events
The National Joint Registry is always pleased to invite all staff in both the NHS and independent sector to attend the NJR annual programme of free-to-attend regional events and our last event took place on 30th October. Due to the uncertainty of COVID-19 we have postponed the planning for any NJR events this year until we know more about the possibility of public gatherings.
By attending an NJR event, once these resume delegates will take away skills to demonstrate the highest possible standards of clinical governance that all hospitals strive to achieve. All staff involved with the NJR process in your hospitals are welcome including: data entry, pre-assessment, theatre, clinical governance staff, surgeons, managers and nurses.
The NJR is a national mandatory audit and so once the new programme dates have been released, time can be requested from your line-manager to support your attendance. This is part of ongoing continuing professional development training and we will be providing certificates for all delegates. The programme presents a unique networking opportunity for all those engaged with the NJR and those involved in assuring data quality and patient safety.

COVID-19 and the associated impact on Elective Surgery
Whilst the National Joint Registry is in alignment with the absolute necessity of surgery postponement in freeing up essential services for those who are in need of these due the spread and impact of COVID-19, we would like to express our empathy with those patients whom the delay will impact and also advise that the British Orthopaedic Association (BOA) has helpfully published some ‘Frequently Asked Questions’ for patients, which they will keep updated throughout the effects of the pandemic.
You can view these FAQs here: https://www.boa.ac.uk/resources/coronavirus-boa-faqs-for-patients.html
Restructure of NJR regional support service
The NJR Regional Coordinator role, originally made up of a team of six, has been replaced by a new role, the NJR Compliance Officer. The Compliance Officer team is now made up of four officers, each with a geographical region of NHS trusts and a group of independent hospitals within their specific remit. The Compliance Officer team will be primarily focussed on providing support to hospital units to achieve compliance with NJR's Key Performance Indicators. This is will be realised through liaison with hospitals, documenting any local challenges they are experiencing and recommending best practice solutions in order to counteract these.
If necessary the NJR Compliance Officers will also escalate any problems encountered through hospital management teams and the NJR's Regional Clinical Coordinators, to attain greater resolution. The NJR's Compliance Officer team also provides training, advice and guidance to all hospital-based NJR stakeholders wherever required.
Hospitals can continue to receive NJR support and request any training that they require by emailing the Service Desk at: email@example.com or by calling 0845 345 9991.
The National Joint Registry welcomes the States of Guernsey on Board
The National Joint Registry (NJR) was delighted to welcome the States of Guernsey onto the registry having extended its data collection, reporting and information services to Guernsey's Princess Elizabeth Hospital (PEH) from the beginning of November 2019.
Three Million Milestone Reached
We are delighted to announce that a patient who had a procedure at The Royal Orthopaedic Hospital has been the three millionth entry in the National Joint Registry!
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 updated the MDS forms for primary and revision shoulder and elbow replacements 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 ‘revision’. 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 NJR MDS forms.

NJR Statement regarding metal-on metal implants
The majority of patients with metal-on-metal hip replacements do very well but because of the negative side-effects that have been experienced by a small number of patients, careful follow-up for all has been important. In accordance with the patient-safety driven mission of the National Joint Registry (NJR), patients with any metal-on-metal implant who have consented to their data being registered, have been identified and recalled for monitoring. Without such a comprehensive registry, working in the interests of patients, hospitals would be unable to identify which patients had specific implants.
The NJR enables the mandatory collection of data on hip, knee, ankle, elbow and shoulder joint replacements and its organisational structure encompasses various specialist groups, such as the implant scrutiny committee, and surgeon performance committee, which closely monitor the performance of implants, hospitals and surgeons. Where there are performance issues, these can be quickly processed and addressed in line with NJR procedures and in the case of implants, referred for consideration by the Regulator [MHRA] and expert representatives, such as those on the Orthopaedic Expert Advisory Group, who proposed the alert and recommendations made regarding metal-on-metal hip implants by the MHRA in 2010.
NJR therefore advises any patients who have had metal-on-metal implants that should they be concerned about symptoms that they consider may be related to their implants, they should consult their Surgeon or GP, who can discuss these with them.
Measuring NJR Compliance:
NJR Compliance measures the proportion of cases reported to NJR, compared to cases reported to other sources of comparative data, such as HES. This provides a basis for NJR to report on the completeness of its data. NJR Compliance is also used as part of the Best Practice Tariff calculation for hip and knee surgery.
Where cases are outsourced to another provider, but reported through HES by the originally commissioned Trust, some procedures may be reported as ‘missing’ from the NJR. This is because the corresponding NJR record will have been submitted by the outsourced provider and the HES record does not accurately record the identity of that outsourced provider. To prevent such cases being reported as ‘missing’ from the NJR, it is essential to complete the ORGANISATION SITE IDENTIFIER OF TREATMENT code field in SUS with the NACS code (formerly the ODS code) of the organisation to which the procedure has been outsourced. Completion of this field enables NJR to exclude the record from the data it expects to be recorded for the Trust, whilst also enabling NJR to ensure that the corresponding record has been submitted by the outsourced provider.
Another important reason to complete the SITETREP field in SUS with the appropriate ORGANISATION SITE IDENTIFER OF TREATMENT code whenever you sub-contract qualifying arthroplasty procedures to other hospitals, is that it ensures that any subcontracting activity is not only picked up but also that the subscription cost for this particular procedure won’t be attributed the Trust. We are unable to track any movements in activity regarding this without this field being completed. It also ensures NJR compliance information is accurate in relation to achieving Best Practice Tariff.
