Learn more about synovitis treatments and related conditions from the articles listed below. Patients who don’t respond to these treatments may be referred to an orthopedic surgeon to discuss a synovectomy, a procedure in which much of the synovium is removed. Medications may include oral drugs known as DMARDs (disease-modifying antirheumatic drugs) and, in some cases, steroid injections. You might find out you have low fluid after synovial fluid analysis. That's partly why joints stiffen and don't move as well over time. All of your joints contain it, but it decreases as you age. Treatment for synovitis usually consists of rest and anti-inflammatory medications. Synovial fluid (joint fluid) is a thick liquid that cushions your joints and reduces friction from the ends of bones moving against each other. This imaging can also help determine what particular grade of synovitis a person has. Imaging, such as an MRI or musculoskeletal ultrasound is often required to make a firm diagnosis. Diagnosing synovitisĪ rheumatologist will aim to diagnose the cause of the patient’s pain by first determining whether it is inside the joint itself, meaning true synovitis, or if it is actually caused by an inflammation of the tendons, referred to as tendonitis (sometimes spelled tendinitis). However, when synovitis is caused by overuse of a joint, the pain usually remains in one spot. The symptoms are often short-lived and may be felt in different parts of the body at different times. In other words, there may be no visible evidence of injury or swelling that is causing pain. The chief symptom is arthralgia, which is Greek for “joint pain.” The pain of synovitis is usually more severe than expected based on the appearance of the joint. ( Osteoarthritis, the more common form of the arthritis, does not involve this type of inflammatory response.)Īrthroscopic camera view of the inside of a knee joint, showing synovitis next to the femoral condyle (upper portion of the femur or thighbone). In these patients, excessive growth of the synovium is part of an abnormal immune response, where the body misidentifies its own natural cartilage as a foreign substance that must be attacked.Ĭartilage loss eventually damages the joint surface and leads to the stiffness and pain characteristic of all types of arthritis. This procedure involves extracting and analyzing a. However, synovitis is also common in people who have some form of inflammatory arthritis. Doctors often use synovial fluid analysis to help determine the cause of joint pain and inflammation. In an active, healthy person, the most common cause of synovitis is overuse of the joint, for example in athletes or people whose jobs involve repetitive stress movement such as lifting or squatting. Contained inside both layers is synovial fluid, a viscous liquid that lubricates the joint to reduce friction on the articular cartilage during motion. It is composed of a tough, outer layer called the fibrous stratum and a soft inside layer (the synovium). The synovium, which is also sometimes called the stratum synoviale or synovial stratum, is connective tissue that lines the inside of the joint capsule.Ī joint capsule, also called an articular capsule, is a bubble-like structure that surrounds joints such as the shoulder, elbow, wrist, hand, knee, foot and ankle. Synovitis (or synovial inflammation) is when the synovium of a joint becomes inflamed (swollen).
