Hip and knee arthroplasties are effective surgical procedures that improve patients’ quality of life, increase their functional capacity and reduce pain. Nevertheless, the technological change under way and the lack of long-term information about many prosthetic models available may lead to the market entry of models with disappointing results.
Most existing registries were created by scientific companies, although they are generally funded by the public. Although the aims of each of the existing registries have been described differently, all could be summarised as dealing with the evaluation and dissemination of results for the purpose of helping to improve the quality of care. Swedish hip and knee registries were the first to be implemented during the 1970s and registries have been developed in other countries ever since.
The Catalan Arthroplasty Register (RACat) came about through an initiative of the Catalan Society of Orthopaedic Surgery and Traumatology (SCCOT), which is attached to the Catalan Health Service (CatSalut) and the Agency for Health Quality and Assessment of Catalonia (AQuAS). The project is managed by AQuAS.
