Zeus Overview

The Zeus is the first KAFO to include dynamic, adjustable extension assistance at the knee and dorsiflexion assistance at the ankle. This newest innovation combines the Icarus Hercules KAFO and the Hermes AFO into a single, modular device. This device is designed for individuals who would benefit from having stability and adjustable assistance at both the knee and ankle joints, while maintaining the ability to quickly detach the AFO and KO portions. This brace provides unparalleled stability and mobility for patients with neuromuscular conditions, post-stroke rehabilitation, and quadriceps or dorsiflexor weakness. Built using advanced 3D-printing technology, the Zeus offers a lightweight, form-fitting, and customized solution that enhances functional mobility while reducing fatigue.

 

Who is This Brace For?

  • Individuals with neuromuscular conditions requiring both knee and ankle support
  • Post-stroke patients needing enhanced gait stability and mobility assistance
  • Patients with quadriceps weakness who require additional knee extension assistance
  • Individuals with foot drop or dorsiflexor weakness seeking AFO functionality
  • Patients with Charcot-Marie-Tooth disease, MS, arthritis, or muscular dystrophy
  • Those with varus/valgus foot and ankle deformities needing customized correction

I was fitted for a custom knee brace by the Icarus team after going through my third ACL and meniscus repair surgery. The brace was delivered quickly after my initial assessment, and I’ve been using it for plenty of activities like hiking, yoga, and surfing. It’s held up extremely well and it’s helped me manage my knee pain! I highly recommend this company.

This brace takes my knee pain down a full step or two (depending on the day) on the pain scale–it lets me go for hikes and long walks and even keep doing aerial arts. It’s the best mobility aid I own, hands down. They even drove two hours to measure, deliver, and fit the brace, and met me in my office.

Trying in every way to extend the timeline before I have to have knee replacement. WHAT AN ABSOLUTE BLESSING my Ascender brace has been! And I can SCUBA dive with it if I need to? BONUS! The staff at Icarus are wonderful, as well…If you experience knee pain or discomfort- I highly recommend getting in touch with Icarus. It will change your life!
