Is calf augmentation with fat transfer a safe procedure?

I've had skinny calves all my life. I've never considered implants due to risks and. Implications associated with it. I recently learned that calf augmentation can be done with fat transfer. I've done research but it doesn't seem to be a very popular procedure. My main concern is weather it is a safe procedure and how likely is the fat to survive. I have enough fat to donate in my my abdomen area. It doesn't seem like there are many doctors who perform this type of procedure. Is it safe? Thank u
