Rotationplasty

Surgical procedure

Rotationplasty is a surgical procedure used to treat bone tumors in children that occur near the knee. The bottom of the femur, the knee, and the upper tibia are surgically removed. The lower leg is then rotated 180 degrees (which is why it's called rotationplasty) and then attached to the femur.
