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.
骨关节炎（OA）是最常见的关节炎，是老年人致残的首要病因。膝关节、手关节、髋关节是OA最常累及的关节。据估计，全球有3.02亿人罹患OA，但OA在全球范围内被严重忽视，对OA的认识和规范化诊疗的普及严重欠缺。中华医学会风湿病学分会在借鉴国内外诊治经验和共识、指南的基础上，制定了本规范，旨在规范OA的诊断、治疗，以减少误诊和误治，改善患者预后。.
