The National Joint Registry (NJR) collects information about hip, knee, ankle, elbow and shoulder joint replacement operations from all participating hospitals in England, Wales, Northern Ireland, the Isle of Man and Guernsey. The registry records patient information and provides data, analysis and reporting on the performance and longevity of replacement joint implants; the surgical outcomes for the hospitals where these operations are carried out, and on the performance outcomes of the surgeons who conduct the procedures.
