Currently no literature study even suggests the hypothesis that this type of fracture may be a fragility fracture. Although the entity is most frequently encountered at the weightbearing surface of the medial femoral condyle, the lateral femoral condyle or the tibia may also be involved (3a,4a). Although low bone density may be present concurrently, it is not the underlying cause of subchondral insufficiency fractures in the majority of patients. 12. A newly recognized clinicopathologic entity. A second fracture can be particularly devastating if it is a hip fracture. It occurs as result of repetitive activity as opposed to a single traumatic event that causes a more traditional break or fracture. SIF occur when normal physiological forces are repeatedly applied to an area of bone compromised by non-tumorous disease, resulting in fracture. These patients may be competing in sports such as gymnastics, track, cross-country, basketball, soccer, etc. The patient was a 20-year-old man who sustained a noncontact left knee hyperextension injury while playing soccer.

The image below shows the importance of immobilisation in this type of injury and there are many supports available these days to help do just that. On MR images, the classic appearance of spontaneous osteonecrosis is a low signal intensity focus beneath the articular surface on T1 weighted images with striking marrow edema within the femoral condyle on fat-suppressed T2-weighted scans.2 The MR appearance in this case thus fulfills the classic diagnostic criteria.

These bones can become especially weak, thin, and frail due to osteoporosis, vitamin D deficiency, or aging. Poor relative muscle condition can also contribute to a lesser extent. Spontaneous osteonecrosis of the knee (SONK). Only recently it is becoming clear that the cause of pain and marrow bone edema that occur subtly in older individuals is, in fact, a insufficiency fracture. Subchondral insufficiency fracture of the knee is not thought to be caused by bone death but instead by osteoporosis and insufficiency fractures, with histopathologically proven origins in weakened trabeculae and applied microtraumatic forces 6,13. Patients with knee insufficiency fracture have a higher prevalence of osteoporosis than the general population.
