Secondary bone marrow edema is caused by pre-existing conditions, which may be interdisciplinary. Hence, this category of BME is commonly found in MRIs, in which the original intention was not to diagnose this particular condition. The different causes of secondary bone marrow edema are listed as follows: [2]

The surgery is performed by arthroscopy, after the joint is cleaned of calcified cartilage. Through use of an awl, the surgeon creates tiny fractures in the subchondral bone plate. [10] Blood and bone marrow (which contains stem cells) seep out of the fractures, creating a blood clot that releases cartilage-building cells.
Medical condition Osteochondritis dissecans A large flap lesion in the femur head typical of late stage Osteochondritis dissecans. In this case, the lesion was caused by avascular necrosis of the bone just under the cartilage.

When the damage increases and the chondral defect reaches the subchondral bone, the blood supply in the bone starts a healing process in the defect. Scar tissue made up of a type of cartilage called fibrocartilage is then formed. Although fibrocartilage is able to fill in articular cartilage defects, its structure is significantly different ...
Microfractures occur later and are accompanied by bone marrow edema, which can be detected on MRI. This stage appears on MRI as an isolated bone marrow edema pattern without a fracture line and is called stress reaction. Then, periosteal new bone forms and may be visible on radiography. Full cortical fractures occur if the repetitive stress ...
Foot and ankle surgery is a sub-specialty of orthopedics and podiatry that deals with the treatment, diagnosis and prevention of disorders of the foot and ankle. Orthopaedic surgeons are medically qualified, having been through four years of college, followed by 4 years of medical school or osteopathic medical school to obtain an M.D. or D.O. followed by specialist training as a resident in ...
New bone outgrowths, called "spurs" or osteophytes, can form on the margins of the joints, possibly in an attempt to improve the congruence of the articular cartilage surfaces in the absence of the menisci. The subchondral bone volume increases and becomes less mineralized (hypo mineralization). [47] All these changes can cause problems ...
