Classification, diagnosis and anatomical considerations in knee dislocations.

Knee dislocations are rare but challenging injuries. Approximately half of them originate from sports. This review describes the diagnostic work-up of knee dislocations. It covers their classification, the initial assessment during the first hours, the secondary assessment during the first two weeks and anatomical considerations. Determining a treatment strategy after knee dislocations requires recognizing the severity of the injury, specifying the extent and location of all damaged structures and understanding their combined effect on joint kinematics.
