Summary
The knee joint consists of three articulations within one joint capsule: articulation between the medial femoral condyle and the medial tibial plateau, between the lateral femoral condyle and the lateral tibial plateau, and between the femoral trochlea and the patella. Imaging for knee trauma includes radiographs of knee as the initial study of choice. Distal femoral fractures can occur in young adults following high-energy trauma and in the elderly following low-energy falls. The most common mechanism in tibial plateau fractures is axial loading following a fall with a twisting force. Knee dislocations usually result from a high velocity motor vehicle accident or fall. Proximal fibular fractures are usually associated with other injuries including tibial plateau fractures following valgus force, and lateral collateral ligament complex injury with varus force. While patellar fractures can occur from both direct and indirect trauma, patellar dislocations are a common cause of hemarthrosis in young athletes.
