Due to the inflammatory nature of RA, drugs to suppress arthritis and immunosuppressants are the main methods of fighting the disease. A form of non-pharmacological treatment in patients who have been taking medications for a minimum period of 3-6 months is a surgical procedure consisting in the removal of the synovial membrane of joint capsules and tendon sheaths. The synovial membrane is the primary focus of inflammation, and its resection prevents the spread of lesions to adjacent tissues and reduces the degree of deformation. Other methods of treatment include rehabilitation, the use of orthoses to stabilize the joints and psychotherapy of the patient (due to the progressive nature of RA).
