Pain in knee osteoarthritis patients associates with distinct pattern of synovitis
#Pain in #knee #osteoarthritis patients associates w/ distinct pattern of synovitis
Objective: To determine patterns of synovitis on contrast-enhanced magnetic resonance images and its relation to pain and severity of radiographic OA. Methods: 86 patients (mean age 62 years, 66% woman, median BMI 29 kg/mm2 and Kellgren-Lawrence score 3 ) with symptomatic knee OA were included. T1-weighted Gd-chelate-enhanced MRI with fat-suppression (3T) were used to semi-quantitatively score synovitis at 11 sites (range 0-22). Self-reported pain was assessed by standardized questionnaires...
Conclusion: Different patterns of synovitis in knee OA were observed. The pattern including several patellar sites was associated with pain, whereas other patterns were not, suggesting a localized response in pain perception in knee OA patients.
