The Global Orthopaedic Registry (GLORY) is an international registry of patients who underwent elective primary total hip arthroplasty (THA) or primary total knee arthroplasty (TKA) during the years 2000 through 2004. By providing a real-world view of practices and outcomes, its objectives are to com-pare practice with evidence-based standards, to identify where such standards do not exist but are needed, and ultimately to lead to hypotheses for improving research, education, and patient care that can be verified by con-trolled clinical trials.
