in all injuries to the tibial plateau radiographs (commonly called x-rays) are imperative. computed tomography scans are not always necessary but are sometimes critical for evaluating degree of fracture and determining a treatment plan that would not be possible with plain radiographs. magnetic resonance images are the diagnositic modality of choice when meniscal, ligamentous and soft tissue injuries are suspected. ct angiography should be considered if there is alteration of the distal pulses or concern about arterial injury.
