Subchondral bone marrow edema is also commonly seen in patients with degenerative joint disease (10 â 14). Subchondral bone marrow edema in patients with osteoarthritis of the knee joint has been associated with knee pain and the progression of articular cartilage degeneration (12, 13).
The term âbone marrow edemaâ was first introduced in 1988. 1 It is characterized by ill-defined areas of decreased signal intensity on T1-weighted MRI and increased signal intensity on T2-weighted images. Bone marrow edema is not the major component of histological anomalies in most situations. For this reason, some authors prefer âbone marrow edema-likeâ signal or abnormalities. 2 Its physiopathology is unclear and varies with the underlying pathological condition.
