What is a subchondral cyst?

Grant Cooper, MD
Physical Medicine & Rehabilitation
In addition to inflammation, damage to the bones is ongoing in osteoarthritis. In essence, sensing the increasing pressure and inflammation, the bones harden (sclerose) and enlarge their defensive perimeter of bone tissue. As the bones enlarge and become sclerotic, fluid-filled pockets can form beneath them. These pockets are called subchondral cysts. The new hard surface created by the bone becomes a further source of irritation, rubbing and scratching the structures around it and perpetuating the cycle of inflammation and damage.
