Osteoarthritis?: Osteopenia is a condition characterized by bone demineralization and subsequent loss of structural density. Pain in the knees resulting from your work history would more likely relate to a similar sounding condition known as osteoarthritis. You should review this with your doctor to prevent administration of an unnecessary test.
