What does subchondral sclerosis mean?

Subchondral sclerosis refers to increased bone density and thickening that often occurs directly beneath a joint cartilage surface, frequently related to osteoarthritis.

- It can be seen on an X-ray as a white opaque area.

- It happens when the bone under the cartilage builds up more density as a response to the degeneration of the cartilage in osteoarthritis.

- It is considered a sign of degenerative joint disease and is often associated with joint pain, stiffness, and decreased range of motion.
