Trabecular edema, also known as bone marrow edema (BME), is a traditional term describing the interstitial fluid accumulation at the trabecular bone marrow. The term was first used in 1988, [ 1 ] referring to the changes in the bone marrow due to inflammation . [ 3 ]
MRI has been proven to be both sensitive and specific for the disease. Both T1 and T2 imaging of the MRI shows bone marrow oedema, subchondral low signal, subchondral crescent linear focus, and focal epiphyseal contour depression. [2]
Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone. [1] OCD usually causes pain during and after sports. In later stages of the disorder there will be swelling of the affected joint that catches and locks during movement.
Edema may be described as pitting edema or non-pitting edema. [32] Pitting edema is when, after pressure is applied to a small area, the indentation persists after the release of the pressure. Peripheral pitting edema, as shown in the illustration, is the more common type, resulting from water retention.
The necrotic bone itself does not show increased radiographic opacity, as dead bone cannot undergo bone resorption which is carried out by living osteoclasts. [2] Late radiographic signs also include a radiolucency area following the collapse of subchondral bone ( crescent sign ) and ringed regions of radiodensity resulting from saponification ...
Osteochondritis is a painful type of osteochondrosis where the cartilage or bone in a joint is inflamed. [1]It often refers to osteochondritis dissecans (OCD). The term dissecans refers to the "creation of a flap of cartilage that further dissects away from its underlying subchondral attachments (dissecans)".
Acute inflammation, like the redness and swelling that occurs with an injury, is a sign that your body is working properly—but chronic inflammation (long-term inflammation that lasts for months ...
The quality of the repair tissue after these "bone marrow stimulating techniques" depends on various factors including the species and age of the individual, the size and localization of the articular cartilage defect, the surgical technique, e.g., how the subchondral bone plate is treated, and the postoperative rehabilitation protocol.
