Abstract
We report a case of an 84-year-old male with multiple levels of canal stenoses who are diagnosed as Charcot arthropathy of bilateral knees. Although he did not feel any pain, recurrence of joint fluid collection and severe instability prevented him from standing and walking. Deficit in superficial sensation and bathyesthesia below the level of Th10, and tendon reflexes of extremities were seen. Romberg test was positive. Laboratory data showed no abnormal findings. We performed bilateral TKA based on the diagnosis of Charcot arthropathy. At 3-year follow-up, there is no complaint about joint instability and collection of joint fluid.
