Techniques of realignment osteotomy in the knee

The procedure has the advantage of improving pain and function of the knee without the surgery actually involving the knee joint itself, as the bone cuts are made either above or below the knee joint. A wedge may be opened up ('opening-wedge') or a wedge may be removed ('closing-wedge') and the new alignment of the limb fixed with plates and sometimes bone grafts until the bone has healed in the new position. The plates may later be removed.
