Figure 1: Osteoarthritis associated with bone marrow edema. (a) Sagittal T1-weighted magnetic resonance imaging (MRI) shows surface irregularities of the anterior slope of the condylar head suggestive of osteoarthritis (arrow). Articular disc is anteriorly displaced (arrowhead). (b) Sagittal T2-weighted MRI of the same joint shows high signal intensity of the condylar head suggestive of bone marrow edema (arrow). Note fl uid effusion in the upper joint compartment (arrowhead)
