Popliteal cysts are usually associated with abnormalities of the knee joint such as osteoarthritis, chronic inflammation or cartilage tears. 15 patients with popliteal cysts demonstrated by arthrography are described who had no obvious lesion of the knee. They had consulted their physician for symptoms without a clearcut relation to the knee joint, such as tenderness on the external side of the calf, ankle edema or paresthesia in the toes. Standard X-rays and clinical examination of the knee were normal except for tender swelling of the popliteal area. The symptoms improved after injection of triamcinolone into the knee joint. Unexplained symptoms of the lower leg may be due to popliteal cysts even in the absence of obvious knee pathology.
腘窝囊肿通常与膝关节异常有关，如骨关节炎、慢性炎症或软骨撕裂。本文描述了15例经关节造影证实有腘窝囊肿但膝关节无明显病变的患者。他们因一些与膝关节无明确关联的症状而就医，如小腿外侧压痛、踝关节水肿或脚趾感觉异常。除腘窝区压痛性肿胀外，膝关节的标准X线检查和临床检查均正常。膝关节注射曲安奈德后症状改善。即使没有明显的膝关节病变，小腿不明原因的症状也可能是由腘窝囊肿引起的。
