There are many types of arthritis, including osteoarthritis, rheumatoid arthritis, infectious arthritis, metabolic arthritis, juvenile idiopathic arthritis, etc. Each has a different treatment method, and the specific types and treatments are as follows: 1. Osteoarthritis: Use crutches or canes to assist with activities and reduce weight bearing on the joints, while avoiding significant activities. Non-steroidal anti-inflammatory drugs are commonly used to relieve pain and improve joint function, such as aspirin and acetaminophen. If the effect of drug treatment is poor, surgical treatment can be considered, such as arthroscopic cleanup, osteotomy, etc.; 2. Rheumatoid arthritis: anti-rheumatic drugs can be selected for treatment, such as leflunomide, salazosulfapyridine, etc. If the effect of drug treatment is poor, and the patient has joint deformity, which seriously affects functional activities, surgery needs to be selected with drug treatment; 3. Infectious arthritis: adequate and effective antibiotics, and when available, bacterial cultures of joint effusions with drug sensitivity tests should be done to enable targeted drug use. The joint cavity can also be punctured every other day or every 3-4 days according to the situation, then inject effective antibiotics, septic inflammation still can not be controlled, systemic toxic symptoms are serious, then should do incision and drainage; 4, metabolic arthritis: common gouty arthritis, the acute phase of the preferred pain medication, such as diclofenac sodium, diclofenac potassium, or celecoxib, meloxicam, etc., after symptom control, discontinued, pay attention to the application period Monitor the blood creatinine level during application. Colchicine can be considered when NSAIDs are ineffective, and should be taken orally in small amounts at the beginning until the symptoms are relieved or until the drug is discontinued when side effects occur; 5. Juvenile idiopathic arthritis: during the acute febrile period, bed rest should be given, and appropriate activities should be performed when the condition improves to prevent joint deformities. Ibuprofen is a commonly used drug, treatment is ineffective or intolerable, should be replaced with other non-steroidal anti-inflammatory drugs under the guidance of a doctor, advanced disease joint deformity combined with dysfunction, feasible joint replacement to improve the quality of life. In addition, patients with arthritis can be assisted with physical therapy, including heat therapy and transcutaneous electrical nerve stimulation, to improve local blood circulation and muscle tone, thereby relieving the pain caused by arthritis, while paying attention to joint warmth, avoiding cold, and reasonable exercise.
