so, What is osteoarthritis?
OA is characterised by the loss of cartilage in synovial joints leading to changes in the periarticular bone.¹ Interestingly there’s more evidence of an inflammatory component to it’s pathology rather than just purely wear-and-tear.
Interesting and important fact:
Only advanced damaged from OA show up on X-rays.¹ Other investigations such as arthroscopy and MRI may be able to show damage in earlier stages.
