For many years, only traditional x-rays have been used to diagnose medial (middle) compartment knee osteoarthritis. If joint space narrowing, osteophytes, and bone-on-bone (severe cartilage deterioration) was found -- you were diagnosed with osteoarthritis. But researchers have found that as an "anterior-posterior technetium bone scan" provides a look at the metabolic activity of the living bone, your knee can be metabolically better or worse than what an x-ray shows. The bone scan looks for loss of osseous (tissue) homeostasis. If found when x-rays still appear normal, there may be time to treat you before irreversible structural changes occur in the knee. Even in patients with established knee osteoarthritis -- it may be possible to metabolically slow down the disease process.
