Levitation® - Knee Extension Assist and Tri-Compartment Unloader™ Knee Brace
The unique tri-compartment unloading knee brace combines multiple technologies to:
Reduce pressure throughout the knee:
Levitation is the only knee brace designed to reduce forces in all three compartments of your knee. Equipped with a patented “bionic” knee extension assist hinge, Levitation absorbs bodyweight, reduces pressure exerted on the knee by the quadriceps.
Realign the knee:
For those with a misalignment of the knee, the optional pneumatic offloader can be added to Levitation . reduces pain, improves strength and stability, and diminishes the risk of falling.
Restore strength with bionics:
energy when you bend your knee and returns that energy as you straighten your leg. and helps protect your knees, allowing you to stay active longer. As your strength increases , the power can be dialed back or turned off altogether.

Levitation sizing is based on customer measurements. Our innovative strapping systems ensure the brace will stay locked in place on your leg by dynamically changing shape to match your leg as you move.
Our sizing process requires three width and three circumference measurements per leg. Once an order has been placed, a Bracing Specialist will instruct you on how to take these measurements to ensure the best possible fit.
With a prescription in hand, most insurance providers will provide coverage for Levitation.
All insurance plans are a bit different and typically vary by region and plan type. You should always follow up directly with your insurance provider for details specific to your plan.
Note that some insurers (in particular in the United States) require a reimbursement code to provide coverage. In the United States, your doctor will prescribe an appropriate HCPCS reimbursement code for custom knee bracing with extension assistance.
We’re confident that our craftsmanship will stand up to everyday use. For purchases made after January 1st, 2020 we offer a 2-year warranty on the brace shell and hinge. We offer a 6-month warranty on soft goods including strapping and padding.
