In brief: Dislocated Knee

A dislocated knee is when the tibia and femur dislocate.
This is a true orthopedic emergency. More common is a patella that is dislocating or subluxating. If the knee truely dislocated then it usually occurs from high speed trauma and a fracture can occur. However, usually the ligaments rupture and i cannot recall seeing a femur fracture. Now bone edema or contusion will invariably occur.

In brief: Dislocated knee

Differentiate between dislocated patella and a dislocated knee--but, yes, both can cause fracture and bone bruise.
Higher energy injury may be the culprit.
