Fat embolism syndrome is caused by the release of fat globules into the systemic circulation. The presentation varies from mild respiratory distress to a devastating clinical scenario that includes hypoxemia, petechial hemorrhages of the skin, and confusion that may lead to coma or death.It is prevalent in 1-5% of patients after trauma to the pelvis, long bones and rarely described in elective total knee replacement.
