NJR Annual Reports analyse the data submitted to the NJR, and highlight the aims and achievements of the National Joint Registry, its Steering Committee and its sub-committees and are released in September each year.
The key analyses of the NJR's 12th, and latest, Annual Report – covering 2014/15 data – were presented as part of the official programme at the British Orthopaedic Association Annual Congress in Liverpool, September 2015.

Data from nearly 2 million procedures are now registered on the NJR with considerable growth expected now that elbow and shoulder replacement data collection is underway (since April 2012) and both Northern Ireland and the Isle of Man have joined the NJR (from February 2013 and July 2015 respectively).
2015 report highlights: Equal focus on revision surgery required if patients are to continue to benefit
While first-time hip and knee replacement operations continue to be hugely successful, when joint replacements require further work (revision or ‘re-do’ surgery) the outlook is not as comparable, the NJR’s 12th Annual Report found.
Now publishing more than a decade of results, the latest report emphasises that for first-time surgery:
- overall life of implants meet national standards, with 95%+ lasting ten or more years
- hip and knee brands offer comparable results and are demonstrating a low risk of revision
- patient factors have a significant bearing on how long the implant will last, with younger patients reporting higher revision rates than their older counterparts
NJR Medical Director Mr Martyn Porter said: “We encourage all those in orthopaedics to pay heed to the results. It is heartening and very encouraging that hip and knee implants are lasting ten years or more, with risk of revision lower than 5%. Joint replacement surgery offers significant benefits – getting patients back to their chosen lifestyle sooner, free from pain and with improved mobility.”
New for this year however, the analysis includes very early results on the relative success of revision surgery. The data confirms that the outcome for the patient is poorer than the first-time surgery – the risk of the implant failing within ten years is much higher than when a first-time implant is replaced.
Today’s study reports that between 2003 (when the NJR was established) and 2014, overall, primary hips and primary knees have at least a 95% chance of survival in ten years after surgery. However, once revised, those figures could drop to around 85%.
