For rheumatic diseases of the knee, the following treatments can be taken: 1. General treatment, during the treatment period, requires the patient to minimize the use of the knee joint, for example, bed rest can be taken. In addition to this, it is also necessary to pay attention to the warmth of the knee joint to prevent it from getting cold and wind. 2. For mild cases of this disease, conservative treatment can be preferred. Conservative treatment requires patients to be treated with anti-inflammatory and anti-rheumatic drugs on the basis of braking. For example, drugs like diclofenac sodium and ibuprofen are often used clinically for anti-inflammatory and pain relief, while anti-rheumatic drugs like methotrexate, salazosulfapyridine, and total peony glycosides are used. In case of extra-articular related complications, other anti-rheumatic treatments should be done accordingly. Chinese physical therapy, such as acupuncture, acupressure, Chinese herbal fumigation and other treatments, have a very good auxiliary treatment effect on such diseases; 3, for the seriousness of such diseases, such as the production of serious joint effusion, joint deformation, it is necessary to take surgical treatment. The principle of surgical treatment is to clean the joint cavity or to perform joint replacement surgery.
