National Joint Registry


The National Joint Registry (NJR) was established in 2002 by the Department of Health and Welsh Government. It collates data on all of the joint replacement operations carried out in England, Wales, Northern Ireland and the Isle of Man. These operations include hip, knee, ankle, elbow and shoulder replacements.

The data is used to assess the outcome of these procedures and determine the effectiveness of different operations and even different types of prostheses. The system assigns a unique number to each patient, which means subsequent operations can be investigated, to see if they are the result of a complication. Ultimately the NJR will help to improve patient care and ensure that high standards are met by participating surgeons.

The NJR is also a useful resource for patients and provides details on the number of hip and knee operations carried out by your surgeon, as well as the national averages. For example, the below chart shows that Mr Nirav Shah performed 227 hip replacements between the 1 April 2017 and 31 March 2018, which is more than four times the national average.
