Osteoarthritis Research Society International (OARSI)

The OARSI is the leading medical society for advancing the understanding, early detection, treatment and prevention of osteoarthritis (OA) through its exclusive dedication to research. OARSI’s area of focus is on OA. With more than 30 years of experience serving the OA community, OARSI provides the necessary framework, expert resources and support for its international constituents to address the challenges of OA so that the knowledge gained can ultimately be used to help improve patient care and patient outcomes.

There have been important advances in the understanding of the pathophysiology of osteoarthritis over the past decade, including OA of the hip. Since hip OA can affect up to 10% of the elderly population, there is a significant need to develop strong methodology for clinical trials of hip OA1. The Osteoarthritis Research Society International (OARSI) established a Task Force to address the issue of clinical trial guidelines for OA in 20122. The intent of the Task Force was to bring together the ideas of academic and clinical physicians, epidemiologists, researchers in the pharmaceutical industry and other interested experts on the conduct of clinical trials generated by the relevant active working groups, and to add sufficient detail to be of help to any party involved in the design of clinical trials.
