The establishment of national joint registers has improved knowledge and quality of data related to joint implantation. Comparing reports of different national registries is crucial to determine potential variations in practices among surgeons and arthroplasty centers and to identify topics for future analysis. In this report, data from these registries in addition to manufacturer reports were used to evaluate procedure volumes and implants utilization trends of primary and revision total hip and knee replacement around the world.
