Ankle synovitis usually recovers in about 2 to 3 months after treatment. Ankle synovitis is mainly caused by inflammation of the synovial membrane of the ankle joint due to overwork or trauma, which manifests as pain, swelling, and limited movement of the affected ankle. Ankle synovitis can only be improved and recovered after active treatment, and common treatments include general treatment, medication, physical therapy, surgery and so on. For general treatment, patients should reduce foot activities to avoid increased inflammatory exudation and aggravation of the condition, and bed rest is recommended. If the pain symptoms are more serious, NSAIDs such as etoricoxib can be considered to reduce the pain. In addition, physical therapy such as hot compresses, ultrashort wave therapy, and microwave physiotherapy can also help relieve symptoms. If synovitis of the ankle still recurs or the symptoms are difficult to be relieved after the above conservative treatments, surgery should be considered. All of the above medications should be used under the guidance of a medical professional. After the occurrence of ankle synovitis, it is recommended that patients seek timely medical treatment, and through active treatment, recovery can usually be achieved in 2 to 3 months.
