Can someone have early stage osteoarthritis for 60 yrs in many joints. Where the oa doesn't show up on mris, CT scans or xrays 4 any of the joints?

Yes. Structural studies of the joints- including ct scans, MRI scans, and xrays show changes usually only after significant damage to the cartilage has occurred. It is possible to have early osteoarthritis and not have changes severe enough to show up on those imaging studies. Thank you for the question.
