Background to and outline of the OARSI treatment guidelines

Kawaguchi: This roundtable discussion is on the Osteoarthritis Research Society International (OARSI) treatment guidelines, of which part 1 has just been published this year and part 2 on consensus recommendations will be published early in 2008. First of all, please could you give a brief outline of the OARSI treatment guidelines, especially in comparison with the former osteoarthritis (OA) guidelines issued by the European League Against Rheumatism (EULAR) and American College of Rheumatology (ACR)?
