Joint replacement surgery: the National Joint Registry

Programme overview

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 in England and Wales on joint replacement operations and to monitor the performance of implants, hospitals and surgeons. Northern Ireland joined in February 2013, the Isle of Man in July 2015 and Guernsey in 2019.

The NJR started collecting data in April 2003 and submission for NHS organisations has been mandatory since April 2011 with the independent sector adhering to mandatory requirements since 2003. Hip and knee replacements have been collected since 2003, ankle joint replacements since 2010 and elbow and shoulder joint replacements since April 2012.

Described as a global exemplar of an implantable medical device registry, the NJR continues to be the largest orthopaedic registry in the world, with an international reputation and now with around 3.7 million procedure records submitted.
