Immobilize leg above and below the injured knee. Cardboard, magazines, or other stiff material that can be used as splints.
Do not try to push knee back into its original position. Manipulating a dislocated joint can cause severe injury.
4. Follow Up
At the hospital, a doctor will realign the joint, perhaps under anesthesia, and assess how much the dislocation has damaged the bones and surrounding tissues and blood vessels.
Treatment may include stabilizing the knee with splints. Surgery is sometimes necessary.
