A joint replacement registry is a system of collecting information of arthroplasty outcomes at a population (often national) level, in order to provide an evidence-base for safe and effective treatment options.
Given the amount of information stored, the data from many of the registries is used as the basis of scientific papers, for example on the metal-on-metal hip controversy.[2]
Worldwide registries
There are currently 31 national members of the International Society of Arthroplasty Registers (ISAR).[3] In addition, in the United States, there are 10 regional or private registries collecting data.
