Safe, stable and yet lightweight

For if you are looking for maximum stability

The UTX STABIL is a lightweight long leg brace (also called KAFO, orthosis, or split) that gives the leg maximum stability. The knee is stabilized throughout the entire
walking cycle. For the ankle there are several choices to achieve the stability that is needed or just to allow the freedom to do that.

Smart manual unlocking

The knee joint can be manually unlocked to allow seating. To this end, a smart lock system was made at the top of the orthosis. At Ambroise we do not find it logical to put the light button next to the lamp on the ceiling so that you can not reach it. The same applies to the unlocking of the knee joint of a leg orthosis. We do not think it’s logical to put it on the knee hinge (as with many conventional systems) so you have to bend a lot to reach it. That’s why the UTX is just on top of the orthosis, which makes it easy for you to reach, even through your clothes.

UTX for people with weakened leg muscles

The UTX STABIL is intended for people who suffer from reduced control over the quadriceps and, consequently, can no longer walk safely and stablely. If there is in addition less control over the stability of the hip, it is sometimes necessary to choose to fully lock the leg while walking, to remain safe standing and walking. Although we like to let you walk dynamically at Ambroise, it must be safe. For example, if it does not work with, for example, an UTX SWING, we will use the UTX STABIL to realize a safe way of walking.


Common illnesses where this may be the case are (among others):

For people who, besides reduced control over the quadriceps, also suffer from a valgus or varus instability of the knee, the STABIL can also be performed as a UTX FS.

If you still have good control over the hip muscles, then the UTX SWING may be a better solution for you. Our clinical experts are happy to work with you to assess which variant best suits your situation.

Not suitable in case of:

  • Overweight (> 120 kg)
  • Knee flexion contracture > 10º
  • Non-correctable valgus / varus > 10º
