Knee joint Most commonly, lipohemarthroses are produced with minimally displaced fractures of the tibial plateau Since cross-table lateral views of the knee in which the x-ray beam is horizontal are commonly performed in trauma patients, lipohemarthroses are more commonly seen with this joint Three bands can normally be distinguished Lipohemarthrosis results from the extrusion of fat and blood from bone marrow into the joint space after an intraarticular fracture. Four patients showed evidence of lipohemarthrosis with either CT (n = 3) or MR imaging (n = 1); in one of these patients, a double fluid-fluid level could be demonstrated retrospectively on plain radiographs.
