UTX® KAFO
The UTX®, was designed and developed by Dr. Nils van Leerdam, of Ambroise Holland bv. It is a lightweight, less than two pounds, knee-ankle-foot orthosis that stabilizes the knee during the stance phase of gait but enables knee flexion during swing phase. At the end of swing phase, as the knee reaches full extension, a ratchet engages to stabilize the knee. A cable runs inside the distal side member from the ankle joint to the knee joint. At the end of stance phase, as the ankle dorsiflexes, this cable linkage causes the knee joint to unlock and destabilize the knee.
The UTX® is also available as a non-stance control KAFO model, "Stable", that locks and unlocks by control of the user. Other models of the UTX® are also available including an "FS" (frontal stability) model to control genu valgum.
The UTX® is a custom fabricated orthoses and must be ordered through our Central Fabrication Department.
