Tibial Osteotomy with Open Wedge
This surgical procedure is used in cases where osteoarthritis has affected only one side of the knee joint. The tibia is cut and realigned so that pressure is shifted from the damaged side of the knee joint to the healthier side.
The patient is positioned so that the knee is clearly visible to the physician, and the area is cleaned and sterilized. An IV is administered for general anesthesia.
Accessing the Knee
An incision is made on the inner side or front of the knee to allow access to the knee joint and the tibia. The joint is examined.
Realigning the Tibia
The tibia is cut at an angle and the two sides are separated to create a wedge-shaped opening. The opening is filled with bone graft. A metal plate is inserted and screws are attached. The metal plate will help hold the wedge open while it heals.
End of Procedure
The incision is closed with sutures or surgical staples and the leg is placed in a splint. A hospital stay of one to two days is necessary, and patients will receive physical therapy. A knee brace and crutches may be needed for up to six weeks after the surgery.
