STONYBROOK, NEW YORK — A young cancer survivor is still able to dance thanks to an innovative surgery. <br />Delaney Unger, 12, was diagnosed with osteosarcoma of the left knee in 2016, which would require chemotherapy and amputation of her knee, according to CNN. <br />Because of the location of her Unger's cancer, doctors were able to perform a rare procedure called a rotationplasty. <br /><br />During a 13 hours surgery in April of 2017, she had her left knee completely amputated. <br />Surgeons then took Unger's ankle and foot, rotated them 180 degrees and attached them to the stump of her thigh, according to Newsday. <br />This allowed her ankle to function as a knee. <br />In October of 2017, Unger received a prosthetic which fits over the backward-oriented foot and extends up the thigh. The prosthesis lets her walk, jump and dance.
