What is Bone-on-Bone Arthritis?

We see people with minor arthritis to what's called bone on bone and kind of describe to the audience what is actually meant by bone on bone. If we look at a patient with what we call bone on bone arthritis, when we look at an X ray we can't see the space, we can't see the cartilage itself, but we can see the space it makes. So on an arthritic X ray you would basically see a significant narrowing of that space to where the bone appears like it's touching on the X ray. And that's what we call bone on bone arthritis. That doesn't necessarily mean that there is no cartilage to regenerate or to treat. It's just that it's extremely thin or extremely damaged. The cartilage is not going to heal by itself. Arthritis is a progressive problem that there's a lot of factors in our own health that can contribute. Arthritis is very simply just that the cartilage surface overlying the bone has been damaged over time and it goes away.
