Welcome

to the National Joint Registry (NJR) website

Hip and knee joint replacements have become common and highly successful operations that bring many patients improved mobility and relief from pain. Thousands of hip and knee 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 Assembly Government to collect information on all hip and knee replacement operations and to monitor the performance of replacement hip and knee joints (implants).
