The knee joint lipohemarthrosis is the best described and understood of the four joints presented in this project. The knee joint encompasses the distal femur and proximal tibia. Typically, lipohemarthroses are produced with minimally displaced fractures of the tibial plateau. The reason that the fat-blood interface is more commonly seen with this joint is that cross table lateral views of the knee are commonly performed in the trauma setting, and the radiographic detection of lipohemarthrosis depends on the x-ray beam being parallel to the fat-blood interface. |
