There are also many signs that we can see on their x-ray that point to aseptic loosening as the cause of their pain. We'll look at the x-ray and we'll notice the debonding occurring right there in the form of what we call radiolucency, or it becomes more dark on the x-ray, especially circumferentially around the implant. This in conjunction with obvious migration or motion of the prosthesis over time when we look at x-rays over the course of their life of the implant, we can see that it has moved or migrated. This is the obvious answer of aseptic loosening, and the only treatment available for this is unfortunately, revision of the knee replacement.
