In radiography, subchondral sclerosis indicates what?

Subchondral sclerosis is the increased density of bone directly beneath the joint surface. This thickening occurs as a remodeling response to increased or abnormal load in degenerative joint disease, most commonly osteoarthritis. OnX-ray it shows up as a whiter, denser line under the cartilage and often accompanies joint space narrowing and osteophyte formation as OA progresses. It distinguishes OA-related changes from infection (erosion and destruction of bone), bone softening from decreased density, or a fracture through the subchondral plate, which would present with a fracture line rather than uniform sclerosis.
