What is subchondral sclerosis of the knee?
What is subchondral sclerosis of the knee?
Overview. Subchondral sclerosis is the hardening of the bone just below the cartilage surface. It shows up in the later stages of osteoarthritis. Subchondral sclerosis is common in the bones found at the load-bearing joints, such as knees and hips.
What is subchondral bone change?
Subchondral bone sclerosis, together with progressive cartilage degradation, is widely considered as a hallmark of OA. Despite the increase in bone volume fraction, subchondral bone is hypomineralized, due to abnormal bone remodeling.
What happens to subchondral bone with osteoarthritis?
Hypothetical model of osteoarthritis (OA) pathogenesis. In early-stage OA, subchondral plate becomes thinner and more porous, together with initial cartilage degeneration. Subchondral trabecular bone also deteriorates, with increased separation and thinner trabeculae.
What to look for in a knee MRI?
MRI features that aid in diagnosis include the location and extent of bone marrow edema, the presence of a fracture line, a hypointense area immediately subjacent to the subchondral bone plate, and deformity of the subchondral bone plate.
Where does a subchondral bone cyst show up?
What Is a Subchondral Bone Cyst? It’s a fluid-filled sac that forms in one or both of the bones that make up a joint. They’re especially common at the knee or hip. The cysts show up just under the tough spongy tissue (called cartilage) that covers the bone near the joint.
How to diagnose osteochondral lesions of the knee?
■ Contrast and compare common entities that manifest as osteochondral lesions of the knee: acute traumatic osteochondral injuries, AVN, SIF of the knee, OCD, bone marrow edema-like lesions, and subchondral cystlike lesions in osteoarthritis. ■ Evaluate MRI findings of each condition and how they pertain to treatment.
How does subchondral sclerosis look on an X-ray?
It shows up on X-ray as a denser area of bone just under the cartilage in your joint, appearing as abnormally white bone along the joint line. Magnetic resonance imaging (MRI) may also be ordered as it is better at imaging soft tissue damage. The presence of subchondral sclerosis can in no way predict how your osteoarthritis will progress.

■ Evaluate MRI findings of each condition and how they pertain to treatment. Several pathologic conditions may manifest as an osteochondral lesion of the knee, which is a localized abnormality of the subchondral marrow, subchondral bone, and articular cartilage.
What do you need to know about a knee MRI?
According to the Radiological Society of North America, an MRI is usually ordered to help doctors diagnose and treat many types of conditions. These include: arthritis and other degenerative joint disorders. bone fractures. damaged cartilage, ligaments, tendons, or meniscus. decreased motion of the knee joint.
