title: Ultrasound for knee effusion: lipohaemarthrosis and tibial plateau fracture.
abstract: Knee trauma and effusion are common Emergency Department presentations. This article outlines the clinician's sonographic approach to knee effusion detection and localisation. A case where lipohaemarthrosis was detected with ultrasound is demonstrated, and the characteristic appearance of this pathology discussed. The sonographic detection of the associated tibial fracture is also demonstrated.
