Abstract
Intraarticular vascularization in 54 knee joints of 27 patients with rheumatoid arthritis was examined by power Doppler sonography. Localization of the vascularity at the suprapatellar recess was classified into two patterns: intracapsular and supracortical. The patients with supracortical vascularization showed a tendency to higher grades of synovitis and higher levels of inflammatory laboratory indices than those with intracapsular vascularization.
