Osteoarthritis is the most common joint disorder to affect the knee and the single most important cause of disability in elderly people. Radiological criteria for osteoarthritis of the knee (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, which contributes to symptoms and disability in advanced disease. Nevertheless, ultrasound examination is very important in early osteoarthritis of the knee when it provides information about soft tissues and cartilage involvement in the absence of clinical symptoms.
骨关节炎是影响膝关节最常见的关节疾病，也是老年人残疾的唯一最重要原因。膝关节骨关节炎的放射学标准（软骨局灶性缺失、骨赘形成、软骨下囊肿和软骨下硬化）仅反映晚期表现和严重的关节损伤。超声检查有助于发现关节周围组织的破坏，这在晚期疾病中会导致症状和残疾。然而，超声检查在膝关节早期骨关节炎中非常重要，因为它能在无临床症状时提供有关软组织和软骨受累情况的信息。
