The National Joint Registry (NJR) collects information on a combination of hip replacements, knee replacements (both total and unicompartmental), shoulder replacements, ankle replacements and elbow replacements.

The NJR Minimum Data Set (MDS) defines the data collected for each surgical procedure recorded in the registry.

Data from surgical procedures should be entered directly into the NJR data entry system. Where this is not feasible, data collection forms can be used by hospital staff to record data, prior to later electronic submission.
