定义
骨关节炎（OA）可被定义为一组不同但重叠的疾病，可能有不同病因，但有类似的生物学、形态学和临床结果，影响到关节软骨、软骨下骨、韧带、关节囊、滑膜和关节周围肌肉。OA是65岁及以上人群中最常见的关节疾病。病因尚不完全清楚，尽管有几个相关因素，如女性性别、遗传、代谢和过度机械应力。OA的诊断主要基于临床病史和身体检查。OA主要影像学特征是承受最大压力区域的关节间隙局灶性/不均匀狭窄，软骨下囊肿，软骨下硬化，和骨刺。
Osteoarthritis (OA) can be defined as a group of distinct, but overlapping diseases, which may have different etiologies, but similar biological, morphological, and clinical outcomes affecting the articular cartilage, subchondral bone, ligaments, joint capsule, synovial membrane, and periarticular muscles. OA is the most common joint disease in persons 65 years of age and above. Its etiology is not fully understood, although there are several related factors, such as female gender, genetics, metabolism, and excessive mechanical stress. The diagnosis of OA is primarily based on clinical history and physical examination. The cardinal radiographic features of OA are focal/non-uniform narrowing of the joint space in the areas subjected to the most pressure, subchondral cysts, subchondral sclerosis, and osteophytes.
