Bone marrow lesions in knee osteoarthritis assessed by dynamic contrast-enhanced MRI with histopathological correlations.

Background: Bone marrow lesions (BMLs) in knee osteoarthritis (OA) have been assessed histopathologically and by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI); however, a direct comparison of the results has not been reported.

Purpose: To evaluate and compare the findings by DCE-MRI and histopathology of subchondral BMLs in knee OA.

Material And Methods: In total, 19 patients with medial tibiofemoral knee OA undergoing total knee arthroplasty were analyzed.
