What causes synovitis?

Synovitis is often associated with joint overuse, trauma, infection, or autoimmune problems. Understanding the causes can help you prevent and relieve this common joint problem.

The synovium is a thin membrane structure in the joints. Its main function is to secrete synovial fluid to lubricate the joints and improve joint flexibility. When the joints are overused for a long time, such as long-term running, jumping and other high-intensity exercises, the synovium may become inflamed due to pressure or friction. In addition, accidental sprains or direct impacts to the joints may also damage the synovium and trigger an inflammatory response. Some people may also have their synovium attacked by bacterial infections or certain immune system diseases (such as rheumatoid arthritis).

Common symptoms of synovitis include joint swelling, pain, limited mobility, and sometimes fluid accumulation in the joints. The severity of the symptoms is related to the cause of the disease. If it is caused by strain, it may be relieved naturally after a period of rest, while symptoms caused by trauma or infection are often more severe. If synovitis is neglected for a long time, it may affect joint function and even develop into irreversible joint damage.

Prevention of synovitis can start with reducing the burden on joints, such as wearing appropriate shoes during exercise, preventing joint injuries, and avoiding excessive repetition of certain movements. Keep warm at ordinary times, especially in cold seasons, otherwise cold stimulation may induce synovitis. If joint pain and swelling occur repeatedly, especially with symptoms of infection such as fever, be sure to go to the hospital in time to identify the cause and receive professional treatment.
