Exercise and stretching the shoulder are the primary means to treat frozen shoulder. Physical therapy, anti-inflammatory medications and cortisone injections may also be prescribed. Most cases of frozen shoulder are resolved non-operatively. However, if the problem is not resolved, surgery may be recommended. The surgeon may perform an arthroscopic capsular release to break up the adhesions. The surgery is an outpatient procedure and can be performed under regional or general anesthesia. Physical therapy following surgery is important in order to regain maximum mobility.
