Description of the Procedure
An incision will be made in the skin above the knee. Next, the muscles will be divided and the blood vessels clamped. A special saw is used to cut through the bone. The muscles are then sewn and shaped so that a stump is formed to cushion the bone. Nerves are divided and placed so they do not cause pain. The skin is closed over the muscles, forming the stump. Drains may be inserted into the stump to drain blood for the first few days after surgery. A dressing and compression stocking will be placed over the stump.
