Understanding Subchondral Bone and Its Role in Joint Health

Subchondral refers to the area beneath the cartilage surface of a joint. In other words, it is the layer of bone that lies underneath the cartilage that covers the ends of the bones in a joint. The subchondral bone is made up of dense, compact bone tissue that provides a foundation for the cartilage to attach to and allows for smooth movement of the joint.

Subchondral bone can be affected by various conditions, such as osteoarthritis, which can cause wear and tear on the cartilage and lead to changes in the subchondral bone. These changes can include the formation of bone spurs or the degradation of the bone tissue, leading to pain and stiffness in the joint.

In summary, the subchondral region is the area beneath the cartilage surface of a joint, and it plays an important role in supporting the movement of the joint and maintaining its health.
