An Army Veteran was injured in 2003 by a rocket-propelled grenade. He suffered multiple infections and endured 24 surgeries. In 2015, he had a right leg above the knee amputation to lessen infection and improve function. He then had osseointegration (OI) surgery in 2019. He uses an Ottobock Genium X3 microprocessor knee prosthetic and does not wear a socket. The algorithms are designed for traditional socket prosthetics, and not for those who had OI.
