Kansas City, Kan- John Kirmer, a 17-year-old high school student, was diagnosed with osteosarcoma after a soccer injury. He underwent chemotherapy and an amputation above the knee followed by rotationplasty, a complex surgery that rotates the lower leg 180 degrees to create a new knee. This procedure allowed him to maintain maximum movement and growth potential.

John's recovery involved physical therapy and support from his community. His mother, Celeste, also faced a cancer diagnosis. John plans to attend K-State's architecture program and participate in the marching band.
