There are many methods that can be used to perform an osteotomy. In one method, imaging technology is used to measure the piece of bone that will be removed. A cut is made in the skin from the knee cap to the top of the shinbone. Several thin wires are placed in the knee to serve as guides, showing where the bone should be cut. An oscillating saw is used to remove the bone wedge. The remaining parts of the bone will be held together with staples, screws, or a plate and screws. The tissue will be stitched together and the area will be closed.
Anesthesia will block pain during the procedure. You will have pain after the procedure. Ask your doctor about medication to help manage pain.
