Possible to Have Fat Grafting on Legs?

It just depends on the areas that you are trying to augment.  It is hard  to augment large volumes in the legs with just fat grafting alone.  This is something that you need to see a surgeon about to really get a good idea.

Fat transfer to the legs are possible. However, patient selection is key. Consult with 3 board certified plastic surgeons who are expert and experienced in fat transfer to understand your options. The cost of fat transfer like other cosmetic surgery varies considerably across the
country and even in the same area. South Florida tends to have lower fees then
more expensive areas such as New York or Los Angeles. We charge starting at $3000 + MD
Anesthesia related costs for fat transfer for the legs. Since you can get quality work
at lower costs, patients will travel from throughout the state, the country,
and internationally to have surgery in South Florida.

To ensure that you are receiving quality work with personalized care at the
most cost effective prices, consult with board certified plastic surgeons that
own their own nationally accredited facilities. The quality must be maintained
at the highest level to maintain accreditation. The surgeons also have
incentive to hire and train quality staff (to ensure that surgery is efficient
and enjoyable), to ensure comfortable and private facilities (to encourage
referral), and to eliminate waste (to ensure that these facilities can compete
effectively).
