Knee osteotomy is a surgical procedure that may be recommended if you have arthritis damage in just one area of your knee. In knee osteotomy, a surgeon removes or adds a wedge of bone to your upper shinbone (tibia) or lower thighbone (femur). This helps shift your body weight off the damaged portion of your knee joint.

Knee osteotomy is most commonly performed on people who may be considered too young for a total knee replacement. Total knee replacements wear out much more quickly in people under the age of 55 than in people over the age of 70.

Many people who undergo knee osteotomy will eventually need a total knee replacement — usually about 10 to 15 years after the knee osteotomy.
