High tibial osteotomy is a surgical procedure to realign the leg and reduce the pain you have from your knee by transferring the body weight to the preserved normal outer side of the knee.
The surgical technique involves making an incision over the tibia, approximately 1 cm distal to the joint line. A wedge of bone is removed, based on the surgeon’s calculations, to allow the angle of the knee to be adjusted.
The space created in the tibia is filled with a bone graft and a metal plate and screws are used to hold the tibia in position while it heals and in a realigned mechanical axis so that there is less pressure/body weight going through the worn area of the knee.
