Osteoarthritis (OA) is the most common joint disorder to affect the knee, and the single most important cause of disability in aged elderly people. Radiological criteria for knee OA (focal loss of cartilage, osteophytosis, subchondral cysts and subchondral sclerosis) reflect late manifestations and significant joint damage only. Ultrasound examination is useful in revealing disruption of the periarticular tissue that contributes to symptoms and disability in advanced disease. Nevertheless, ultrasound examination is very important in early OA of the knee when it can give information about soft tissues and cartilage involvement also in absence of clinical symptoms.
骨关节炎（OA）是影响膝关节最常见的关节疾病，也是老年人群残疾的唯一最重要原因。膝关节OA的放射学标准（软骨局部缺失、骨赘形成、软骨下囊肿和软骨下硬化）仅反映晚期表现和显著的关节损伤。超声检查有助于发现关节周围组织的破坏，而这种破坏会导致晚期疾病的症状和残疾。然而，超声检查在膝关节早期OA中非常重要，因为即使在没有临床症状的情况下，它也能提供有关软组织和软骨受累的信息。
