Patients with ankle effusion, if caused by trauma, usually can not walk temporarily, if caused by chronic arthritis, patients can walk, the details are as follows: First, trauma-induced ankle joint effusion, due to local swelling, pain and restricted activity, patients should not walk, walking will aggravate the condition and is not conducive to injury repair. Second, patients with chronic osteoarthritis of the ankle joint can develop synovitis secondary to joint effusion. If the amount of effusion is not large, patients can walk appropriately, but walking time and distance should be strictly limited to avoid aggravating the inflammation and leading to an increase in effusion. If the joint effusion is large, resulting in joint swelling, the patient is not suitable for normal walking, otherwise the effusion is difficult to absorb and the symptoms cannot be relieved. Therefore, patients with effusion in the ankle joint should decide whether they can walk according to the specific situation.
