Knee osteotomy is a surgical procedure that your doctor might recommend if you have arthritis damage in just one area of your knee. Osteotomy is also performed in combination with other types of knee surgery, such as cartilage surgery, if your leg is bowed or knock-kneed.
The procedure involves removing or adding a wedge of bone to your shinbone (tibia) or thighbone (femur) to help shift your body weight off the damaged portion of your knee joint.
Knee osteotomy is most commonly performed on people who are younger than 60 who are active. Many people who undergo this procedure for arthritis might need a total knee replacement — usually about 10 to 15 years after the knee osteotomy.
