Correlation of the Development of Knee Pain With Enlarging Bone Marrow Lesions on Magnetic Resonance Imaging.

The article discusses a study which investigated the association between development of knee pain and the enlargement of bone marrow lesions (BMLs). The authors asked twice the subjects with knee ostheoarthritis (OA) or at high risk of knee OA about the presence of knee pain, aching or stiffness. They used magnetic resonance imaging and multiple logistic regression to assess whether an increased BML score is predictive of the development of knee pain.
