We report a rare case of degenerative joint disease of both knees, complicated by a Baker cyst. Our emphasis is on the role of electromyography and electrodiagnosis in the localization of this nerve entrapment syndrome. The patient presented with pain and swelling; venography revealed deep venous thrombosis of the right calf, including the popliteal and proximal superficial femoral vessels. The patient responded well to bed rest, analgesics, intravenous heparin and subsequent Coumadin anticoagulation, and was discharged two weeks later. Five weeks after onset of these acute problems, nerve conduction studies were done, leading to a diagnosis of Baker cyst with nerve entrapment. He responded well to knee joint aspiration and intraarticular prednisolone injection. Some evidence of improvement in the flexor hallicus longus muscle was detected at three-month follow-up.
我们报告一例罕见的双膝退行性关节病，并发腘窝囊肿。我们重点关注肌电图和电诊断在这种神经卡压综合征定位中的作用。患者表现为疼痛和肿胀；静脉造影显示右小腿深静脉血栓形成，包括腘静脉和股浅静脉近端。患者对卧床休息、镇痛药、静脉注射肝素及随后的香豆素抗凝治疗反应良好，两周后出院。这些急性问题出现五周后进行了神经传导研究，诊断为腘窝囊肿伴神经卡压。他对膝关节穿刺和关节内注射泼尼松龙反应良好。在三个月的随访中发现拇长屈肌有一些改善迹象。
