In a dislocation of the knee, the bones in the knee are displaced. When they are displaced they do not fit together correctly. For this to occur, many ligaments must be torn.
Ligament are strong bands of tissue that connect one bone to another.
The doctor will review your cause of injury and symptoms and examine you. The doctor will order x-rays to see if any bones are broken. The doctor will also check your pulse at your ankle and possibly order a test called an arteriogram to make sure blood vessels are not blocked. To do an arteriogram, the doctor injects a solution into your arteries through a tube, or catheter. This solution is visible on x-rays.
