There is no so-called best way to eliminate elbow joint effusion. Different treatment methods should be adopted according to different diseases, mainly trauma, osteoarthritis and rheumatoid arthritis and other diseases. 1. Trauma: If the elbow joint effusion is caused by trauma, the elbow joint should be braked and rested for a short period of time, and continuous cold compresses should be applied for about three days, and after three days, it can be changed to localized hot compresses to accelerate the swelling to further subside. After the above treatment, traumatic elbow joint effusion will gradually disappear. 2. Osteoarthritis: If the elbow joint effusion is caused by chronic diseases such as osteoarthritis of the elbow joint, it needs to be supplemented with ultrashort wave therapy, microwave therapy, and non-steroidal anti-inflammatory drugs such as celecoxib and other comprehensive treatment. 3. Rheumatoid arthritis: Rheumatoid arthritis of the elbow joint can also cause elbow joint effusion, which requires anti-rheumatic treatment with drugs such as methotrexate. After the above treatment, the inflammatory reaction in the elbow joint will be relieved for a short period of time, and the joint effusion will be gradually absorbed, but the cause of the disease has not yet been completely removed, so the joint effusion will recur, leading to accelerated degeneration of the joint. When elbow joint effusion occurs, it is recommended to go to the hospital in time, complete the relevant examinations and carry out targeted treatment or therapy under the guidance of the doctor.
