My daughter was born with a shortened achillies tendon and after four years of casting to stretch this muscle naturally, we decided to permanently fix with surgery. As a result, her left calf muscle has never reached full development. She is now 17 and painfully aware of this difference. She has tried numerous exercises to no avail and has asked us to look into plastic surgery. We were told 13 years ago there was no procedure to correct this. Have medical advances been made in this area? If so, what is the approximate cost of the surgery? Is she a candidate or is she still too young? Thank you in advance for help, she started college this year and is not feeling too good about herself.
