Abstract

Knee dislocations (KD) once believed to be rare injuries are being seen more frequently for a variety of reasons. Because of its increasing incidence, an orthopedic practitioner is likely to be faced with caring for a patient with a knee dislocation in his/her practice. It is essential for practitioners to be able to classify and communicate with each other accurately, and classification systems can be of some use. In this chapter, we will discuss the four primary classification systems: position (Kennedy classification), energy/velocity of injury, pathophysiologic, and anatomic systems. The position system classifies the KD by relation of the tibia with respect to the femur. The energy of injury system classifies the KD by mechanism of injury and body habitus. The pathophysiologic system identifies KD by stress radiography. The anatomic system classifies the KD by the injured structures based upon clinical examination. While all systems have their uses, the anatomic system is the most comprehensive and useful in relaying information and prognosis.
