Findings: Comminuted fracture of the tibial plateau.  Lateral view demonstrates lipohemarthrosis. 
Diagnosis: Comminuted tibial plateau fracture.
Discussion: Lipohemarthrosis is a fluid-fluid level caused by less-dense fat layering above more-dense blood products.  Post-traumatic lipohemarthrosis is caused by bleeding from laceration of synovial vessels or leakage from marrow cavity.  Lipohemarthrosis always signifies intra-articular fracture.  This is the only way marrow fat can enter joint.
