The following criteria apply to lesions without overlying cartilage abnormalities: in the weight-bearing area of the involved condyle, subtle flattening or a focal depressive deformity, an irregular, discontinuous hypointense line in the subarticular marrow, representing callus and granulation tissue, there may be a fluid-filled cleft within the subchondral bone plate (poor prognostic factor) 13, excavated defect of the articular surface (advanced cases), focal subchondral area of low signal intensity subjacent to the subchondral bone plate representing local ischaemia (considered most important in early lesions and a specific MRI finding12), this area shows no enhancement on post-contrast; if it is thicker than 4 mm or longer than 14 mm, the lesion may be irreversible and may evolve into irreparable epiphyseal collapse and articular destruction, appears as a thickened subchondral bone plate, which represents a fracture with callus and granulation tissue and secondary osteonecrosis in the subarticular region 13, ill-defined bone marrow oedemaand a lack of peripheral low signal intensity rim as seen in osteonecrosisand bone infarcts.

However, there are specific stress fractures in certain patients that may be treated surgically at their initial presentation. other etiologies (post-traumatic, infectious, inflammatory diseases). If we take a normal paperclip and begin to repetitively stress the paperclip by bending it back and forth, eventually the metal weakens in the center and will get small defects or cracks before it finally breaks in two. Takeda M, Higuchi H, Kimura M et-al. Consequently, there are currently insufficient data on the epidemiology and evolution of other fragility fractures, also known as non-vertebral non-hip fracture (NVNH). Subchondral insufficiency fracture of the knee (SIFK) is a potentially devastating disorder that may progress rapidly to osteoarthritis with articular surface collapse.
