[Recommendations on the diagnosis and treatment of osteoarthritis in China].

Osteoarthritis (OA) is the most common form of arthritis and the leading cause of old age disability, affecting an estimated 302 million people worldwide. OA is seriously overlooked in the world. The awareness of OA and the popularization of standardized diagnosis and treatment are all lacking. Knees, hips, and hands are the most commonly affected joints in OA. Based on the experience of diagnosis and treatment, consensus and guidelines, we formulated this diagnosis and treatment standard in order to standardize the diagnosis and treatment of OA. We hope that our standard can reduce misdiagnosis and mistreatment and improve the prognosis of OA.
