A knee dislocation occurs when the bones that form the knee are out of place. A knee dislocation, more specifically, is when the bones of the leg (the tibia and fibula) are moved in relation to the bone in the thigh (femur). The bones of the knee are held together by strong bands of tissue called ligaments.
What parts of the knee can dislocate?
Dislocated Knee: What You Need to Know
- femur (thighbone)
- patella (kneecap)
- tibia (shinbone)
What is the most common knee dislocation?
Anterior: most common dislocation (50-60%) and occurs from hyperextension of the knee resulting in tearing of the posterior structures. This injury drives the distal femur posterior to the proximal tibia. Posterior: most commonly associated with popliteal artery injury.
