Radiology of the suprapatellar region.

The gross and radiological anatomy of the suprapatellar region has been reviewed and its clinical application outlined. In most patients an accurate assessment of the presence of effusion and lipohaemarthrosis of the knee joint can be made and the possibility of excluding joint disease is discussed. In the individual patient the careful application of the radiological anatomy of this region may prevent mistakes in the localisation of various pathological processes.
