Osteoarthritis research society international (OARSI) guidelines for the non-surgical management of knee, hip, and polyarticular osteoarthritis in 2019 contained some recommendations in treating patients with osteoarthritis (OA) who are considering non-surgical treatment. Compared with domestic consensus on diagnosis and treatment for OA, this clinical practice guideline (CPG) prepared by OARSI had some advantages in terms of methodology selection and recommendation. Therefore, it is necessary to interpret this CPG to accelerate the understanding and dissemination of the CPG. The ultimate aims were: to strengthen the normative and understanding of non-surgical treatment of OA; to enhance the understanding of clinicians for this CPG in treating OA; to accelerate the development of guideline development methodologies in China; to provide methodological guidance for the development of CPG based on the current situation in China.
