Rasonté was diagnosed with Sickle Cell Disease just past her first birthday. Before her first appointment at the Sickle Cell Clinic, she fell sick and eventually had to have bilateral below knee amputation and later, bilateral below elbow amputation.
In 2005, after a fundraiser, she was fitted with new below knee prosthesis and her first myoelectric below elbow prosthesis at a clinic in Houston, Texas, USA. Like most children, Rasonté has her growth spurts. This means that prosthetics bought and fitted have to be changed every two years or so. This is very expensive as just one prosthetic can cost over US$10,000.
