The little girl had the surgery in Florida in mid-January after her family raised $300,000 to cover the cost.

Mia was born with a congenital femoral deficiency, a condition that caused her hip and femur to be underdeveloped at birth. The result is that her left leg is significantly shorter than her right and she uses a prosthesis.

The surgery, basically, rotated her leg backwards and created something of a new hip joint. Rotating her foot will allow her ankle to act like a knee and, says mum Leila Bright, she will have a new prosthesis.

Ahead of the surgery,  the family started the Mia's Big Adventure Facebook page to kept people up to date with her progress.

Ms Bright posted that during the overall surgery, little Mia actually underwent 29 individual procedures.

Since the surgery, Mia has been having treatments in a hyperbaric chamber to help her wounds heal more quickly, undertaking physiotherapy and attending follow-up appointments.

Reflecting on the three years that had passed between when Mia was fitted with her first prothesis and being in Florida for the surgery, Ms Bright wrote: "If you have told me then, that we would be here now, in America, having raised over $300,000 thanks to a whole bunch of amazingly generous people and that she would have a backwards leg, I probably would have laughed".

"The girl's got some sass about her and she’s always ready to use it to keep getting back up," she wrote.
