| Abstract |
| Abstract In the present study, 49 knee joints
of 26 patients with rheumatoid arthritis and 17 knee joints of
17 healthy subjects were ultrasonographically examined. Lateral,
superior, and medial aspects of the patella were scanned using
an ultrasonograph with a 7.5-MHz annular array transducer to evaluate
the thickness of synovial effusion and the synovial proliferation
pattern. The overall mean thickness of synovial effusion (mean
of all three sites) in the knee joints was 4.9 - 3.4 mm for rheumatoid
arthritis patients and 1.4 - 0.5 mm for healthy subjects. In rheumatoid
arthritis patients, the mean thickness of synovial effusion at
the superior aspect of the patella (6.5 - 4.1 mm) was significantly
greater than that at the lateral aspect (4.5 - 4.8 mm) (P < 0.05)
and the medial aspect (4.0 - 3.1 mm) (P < 0.01). Patients with
the villonodular pattern of synovial proliferation had a shorter
duration of disease than those with uniform thickening or an overlapping
pattern. |
