They can develop in … To understand what subchondral sclerosis is, it helps to have a clear picture of how osteoarthritis affects the joints of the body. Subchondral sclerosis: This is increased bone density or thickening in the subchondral layer, seen on X-ray for osteoarthritis. MRI is more sensitive to small subchondral cysts than x-ray, demonstrating well-defined rounded areas of fluid-like signal intensity on non-enhanced imaging [7, 8]. A comprehensive study of femoral heads of patients and cadavers with osteoarthritis, rheumatoid arthritis, osteonecrosis, and calcium pyrophosphate dihydrate deposition disease allows insight into the radiographic and pathologic appearance of subchondral radiolucencies in these disorders. Clinical quantitative computed tomography (QCT) has the potential to characterize cysts in vivo but it is unclear which specific cyst parameters (e.g., number, size) are associated with clinical signs of OA, such as disease severity or pain. At baseline, each subject had a weight-bearing anteroposterior tibiofemoral radiograph taken of the symptomatic knee in full extension. ... Girolimetti R, De Angelis R, et al. The presence of marginal osteophytes and subchondral cysts detected with conventional radiography and tomosynthesis was compared with that detected with MR imaging in the knee, as a whole and according to location (ie, medial or lateral, femur or tibia). A large subchondral cyst may be referred to as a geode. Plain X-ray is an imprecise tool for monitoring the subchondral bony changes associated with the development of knee osteoarthritis (OA). Arthritis Care Res (Hoboken). A subchondral bone cyst (SBC) is a fluid-filled sac that forms in the bone just beneath the cartilage of a joint such as the hip, knee, or shoulder. Subchondral cysts or erosions, as well as fractures (eg, odontoid), may be observed. Osteoarthritis (OA) of the knee joint is a common degenerative joint disease. The fracture of the subchondral bone plate can show two patterns at MRI (19,29): (a) depression of the subchondral bone plate with loss of epiphyseal contour or (b) more rarely seen in the knee, a high-signal-intensity line on T2-weighted MR images extending under the subchondral bone plate representing fluid accumulating in the subchondral fracture cleft. Overlying full-thickness cartilage fissures or defects are often present. Knee osteoarthritis (OA) is a painful and debilitating disease characterized by cartilage deterioration and altered subchondral bone. This lesion occurs near arthritic joints, especially the hip and knee. If this fluid escapes into soft tissue behind the knee, a so-called baker’s cyst may develop (Figure 2). The initial radiographs may not … An individual is predisposed to developing Subchondral Bone Cysts when he or she is either obese or is heavily nicotine dependent. On contrast-enhanced MRI, it is widely accepted that the fluid-equivalent part of most cystic lesions demonstrates no enhancement after intravenous administration of paramagnetic contrast material. Histopathological alterations in the subchondral bone, including BMELs, SBCs and microdamage, are also highly associated with the progression of OA. Crossref, Medline, Google Scholar Subchondral cysts may be a late feature of OA of the knee as part of the pathological basis for disease. Clinical quantitative computed tomography (QCT) has the potential to characterize cysts in vivo but it is unclear which specific cyst parameters (e.g., number, size) are associated with clinical signs of OA, such as disease severity or pain. The advanced cases of OA are usually associated with formation of subchondral bone cysts (SBCs) (Ondrouch, 1963).Nearly 50% of knee OA cases present with SBCs (Wu et al., 2007; Raynauld et al., 2008).In the majority of cases, these are spherical or ellipsoidal in shape and located at the articular surface.
