The National Joint Registry (NJR) collects information about hip, knee, ankle, elbow and shoulder joint replacement operations (arthroplasty) from all participating hospitals in England, Wales, Northern Ireland, the Isle of Man and the States of Guernsey. As the largest data collection of its kind in the world, the NJR has been described in UK Parliament as a global exemplar of an implantable medical devices registry.
