“…SIFs typically are observed along the central weight-bearing aspect of the femoral condyle (60%-90%), but they also may involve the central tibial plateau, and less commonly, the periphery of the articular surface (18)(19)(20)(21). At MRI, SIF is associated with marked bone marrow edema emanating from the subchondral region and extending over large areas (10,17,18), often involving the entire femoral condyle.…”

“…This association and a link between SIF and meniscectomy (26) support the proposed role of mechanical stress in the development of SIF and emphasize the rationale for meniscal conservation. Although they are not essential for the diagnosis of SIF, associated cartilage abnormalities are often present (18,21). The overall extent of meniscal abnormality and cartilage loss in the joint and decreased knee range of motion at the time of presentation are associated with clinical progression (21).…”

Osteochondral Lesions of the Knee: Differentiating the Most Common Entities at MRI

et al. 2018

Several pathologic conditions may manifest as an osteochondral lesion of the knee that consists of a localized abnormality involving subchondral marrow, subchondral bone, and articular cartilage. Although understanding of these conditions has evolved substantially with the use of high-spatial-resolution MRI and histologic correlation, it is impeded by inconsistent terminology and ambiguous abbreviations. Common entities include acute traumatic osteochondral injuries, subchondral insufficiency fracture, so-called spontaneous osteonecrosis of the knee, avascular necrosis, osteochondritis dissecans, and localized osteochondral abnormalities in osteoarthritis. Patient demographics, the clinical presentation, and the role of trauma are critical for differential diagnosis. A localized osteochondral defect can be created acutely or can develop as an end result of several chronic conditions. MRI features that aid in diagnosis include the location and extent of bone marrow edema, the presence of a fracture line, a hypointense area immediately subjacent to the subchondral bone plate, and deformity of the subchondral bone plate. These findings are essential in diagnosis of acute traumatic injuries, subchondral insufficiency fracture, and its potentially irreversible form, spontaneous osteonecrosis of the knee. If the lesion consists of a subchondral region demarcated from the surrounding bone, the demarcation should be examined for completeness and the presence of a "double-line sign" that is seen in avascular necrosis or findings of instability, which are important for proper evaluation of osteochondritis dissecans. Subchondral bone plate collapse, demonstrated by the presence of a depression or a fluid-filled cleft, can be seen in advanced stages of both avascular necrosis and subchondral insufficiency fracture, indicating irreversibility. Once the diagnosis is established, it is important to report pertinent MRI findings that may guide treatment of each condition.

The role of radiography and MRI for eligibility assessment in DMOAD trials of knee OA

et al. 2018

Currently no disease-modifying drugs for osteoarthritis have been approved. There are several reasons for failure of clinical trials in the past, including the commonly applied definition of structural eligibility based on radiographic assessment. In the context of precision medicine it will be of increasing relevance to find the appropriate patient for a specific treatment approach. Phenotypical stratification by imaging at eligibility will be paramount in the future and cannot be achieved using radiography alone. Furthermore, joints at high risk for faster progression need to be identified, as these may allow a more efficient DMOAD trial design. In addition, joints at high risk for collapse need to be excluded at screening. MRI may be able to offer solutions in this context, and commonly perceived hurdles in the application of MRI at eligibility assessment are being addressed as a result of technological advances and simplified image assessment.

Femoral condyle insufficiency fractures: associated clinical and morphological findings and impact on outcome

Abstract: FCIF are frequently associated with overlying cartilage loss and ipsilateral meniscal injury. The extent of cartilage loss and meniscal damage, in addition to loss of knee range of motion at the time of presentation, are significantly associated with clinical progression.
