Definition:
A knee dislocation occurs when the bones that form your knee are out of place and is due to paralysis, synovitis, infection, or other disease. The bones of your calf (the tibia and fibula) get moved compared to the bone of your thigh (femur). The bones of your knee are held together by strong bands of tissue, called ligaments. For a knee dislocation to happen, these bands have to tear.
