Question 239 · LEK · Osteoarthritis

The diagnosis of osteoarthritis is based on clinical signs and symptoms. In the case of a non-characteristic clinical picture the imaging examinations are recommended, of which the examination of choice is:

1) magnetic resonance scan, as it allows the imaging of all joint structures, including the marrow;
2) ultrasonography of knee joints, as it allows the imaging of soft tissues of the joints;
3) computed tomography of the affected joint, as it allows the precise imaging of bone structures;
4) classical X-ray of the affected joint;
5) bony scintigraphy that allows the evaluation of blood flow related to inflammation in all the joints.
The correct answer is:
  1. A. all the above.
  2. B. only 1.
  3. C. 1,2,3.
  4. D. only 4.
  5. E. only 5.

Even when imaging is needed in degenerative joint disease, the first-line study is the simplest and most widely available one.
