After the knee joint effusion is pulled out, will it appear repeatedly?

The effusion of knee joint is actually synovitis of knee joint. When degenerative knee arthritis is complicated with synovitis, effusion will appear in the joint. In addition, arthritis caused by rheumatism, arthritis caused by pathogenic bacteria infection and metabolic arthritis such as gout can all cause knee joint effusion. The surface of the joint is covered with a layer of cartilage, and the outside is wrapped with a pocket-shaped joint capsule. In the inner layer of the joint capsule, there is a tissue called synovium, which can produce joint fluid and deliver nutrition and lubrication to cartilage. However, with the increase of age, cartilage gradually becomes thinner due to wear, causing degeneration and eventually leading to synovitis. After synovitis, more synovial fluid needs to be secreted, and the synovial fluid keeps accumulating, forming the so-called "effusion" symptom. When knee effusion causes inflammation and severe pain, just pump it out. Many people think that "pumping out the accumulated fluid will lead to accumulated fluid more easily". In fact, after the joint fluid is extracted, it will not be more prone to water accumulation, but if the root causes such as inflammation are not eliminated, even if the joint fluid is extracted, it will only take about a week, and water accumulation will occur in the knee joint. If the joint fluid accumulated in the knee joint is ignored, there will be symptoms such as increased pain and inability to bend the knee. Therefore, if necessary, the effusion should be pumped out, but in medical institutions, we should pay attention to appropriate conservative treatment and exercise treatment, and at the same time, we should take some appropriate treatment methods in our lives. During the treatment, we should not only draw out the effusion, but also inject drugs outside the joint. Now the injection is mainly sodium hyaluronate. As sodium hyaluronate is a viscoelastic substance, it can lubricate joints, protect cartilage on the surface of joints, effectively prevent cartilage damage and finally relieve pain. Sometimes adrenocortical hormones such as steroids are also used to quickly eliminate joint inflammation and pain. Because steroids have a strong analgesic and anti-inflammatory effect, the pain will be relieved quickly, and people with walking difficulties can return to normal walking. However, if this drug is used for a long time, it will aggravate cartilage damage, so it is not recommended to use it unless absolutely necessary. Either way, there is a risk of infection in the internal treatment of joints, so not only local disinfection, but also anti-infection measures should be considered later. Especially people with diabetes at the same time, especially need to pay attention to this.
