Pathophysiologic and prognostic value of ultrasonography in knee osteoarthritis

Abstract

Presence of Baker’s cyst showed statistically significant associations with both clinical (OR: 3.07; 95% CI: 1.21 – 7.78) as well as radiological (OR: 2.84; 95% CI: 1.17 – 6.90) progression. Synovial hypertrophy showed a weaker but consistent association with clinical as well as radiologic progression (OR: 2.11; 95% CI: 0.80 - 5.57). These inflammatory variables might be candidate features to help identify knee OA patients with worse prognosis and could contribute to phenotyping patients on basis of structural pathology.
