Synovitis is a medical condition characterized by inflammation of the synovial membrane, which lines the joints in the body. It is commonly associated with chronic inflammatory conditions such as rheumatoid arthritis, but can also occur due to infection, injury, or overuse of the joint. Symptoms of synovitis include pain, swelling, stiffness, and limited range of motion in the affected joint. Treatment typically involves addressing the underlying cause of the inflammation, such as medication, physical therapy, or in severe cases, surgery. Research in the field of synovitis focuses on understanding the underlying mechanisms of inflammation in the synovial membrane, developing new treatment options, and improving patient outcomes.
