![]() Treatment for Acetabular Subchondral CystsĪcetabular subchondral cysts may not cause any symptoms. During the examination, if pain, swelling, or stiffness is noted and your physician presumes it to be a sign of osteoarthritis, rheumatoid arthritis, or joint injury, your physician may order tests such as X-rays, MRIs, and CT scans for a detailed evaluation of hip joint structures and to confirm the presence of acetabular subchondral cysts. In order to diagnose acetabular subchondral cysts, your physician will review your symptoms and conduct a thorough physical examination of the hip to determine which motions are restricted or painful. Some of the signs and symptoms of acetabular subchondral cysts include:ĭiagnosis of Acetabular Subchondral Cysts However, other symptoms may occur as a result of the underlying disease conditions such as osteoarthritis and rheumatoid arthritis. ![]() The cysts by themselves do not seem to cause any symptoms, other than protrusion of soft tissue in the acetabulum in rare cases. Signs and Symptoms of Acetabular Subchondral Cysts Some of the common risk factors for acetabular subchondral cysts include: Risk Factors for Acetabular Subchondral Cysts In some instances, a joint injury might also result in a cyst without OA.Īcetabular subchondral cysts can also form in cases of rheumatoid arthritis, another common form of arthritis, in which your immune system attacks and inflames your joints. This affects the normal, smooth, sliding of one bone against another in your joints, causing more friction. Causes of Acetabular Subchondral CystsĪcetabular subchondral cysts are commonly caused by osteoarthritis (OA), a degenerative joint condition and the most common form of arthritis, in which the cartilage between the joint wears away due to wear and tear over time or because of an injury to the joint. The cysts primarily consist of hyaluronic acid, a liquid in the joint fluid that lubricates the joint. The joint surface is covered by a smooth articular cartilage that cushions and enables smooth movement of the joint.Īcetabular subchondral cysts develop just under the cartilage (tough spongy tissue) that covers the acetabulum and may cause joint pain and discomfort. The hip joint is a ball-and-socket joint in which the head of the femur forms the ball and the pelvic acetabulum forms the socket. Subchondral bone acts as a shock absorber in a weight-bearing joint. The suffix ‘chondral’ means cartilage, while the prefix ‘sub’ means below. Subchondral bone is the layer of bone just below the cartilage in a joint. Acetabular subchondral cysts are fluid-filled sacs or spaces that form in the acetabulum (hip socket) side of the hip joint.
