An osteotomy is a surgical operation whereby a bone is cut to
shorten, lengthen, or change its alignment. Osteotomy
is one method to relieve pain in arthritis and may delay
progression of arthritis, especially of the hip and knee.
Osteotomy of the knee
Knee osteotomy is commonly used to realign arthritic
damage on one side of the knee. The goal is to shift the
patient's body weight off the damaged area to the other
side of the knee, where the cartilage is still healthy.
Surgeons remove a wedge of the tibia from underneath the
healthy side of the knee, which allows the tibia and
femur to bend away from the damaged cartilage.
