Össur Exoform Knee Immobilizer Brace – Post-Op & Knee Ligament Support
The Össur Exoform Knee Immobilizer is a clinically designed knee immobilizer brace that holds the knee in full extension during post-injury recovery, post-operative healing, and ligament protection. Its patented Slide-to-Size adjustment system and dual-cuff design deliver a superior, customizable fit without the guesswork of traditional sizing. Available in Cool Foam (breathable mesh) and Full Foam (standard padding) versions, with a 3XL Full Foam option for larger leg circumferences.
What is a Knee Immobilizer?
A knee immobilizer is a rigid or semi-rigid brace that holds the knee in a straight (extended) position. It is commonly prescribed after knee surgery, ligament injuries, or fractures to prevent bending and protect healing tissue. Unlike a hinged knee brace, a knee immobilizer does not allow controlled range of motion — it is designed for full immobilization as directed by your clinician.
Cool Foam vs. Full Foam — Which should I choose?
- Cool Foam (222100) — Breathable mesh foam panels with ventilation. Best for warmer climates, active patients, or extended wear where heat and moisture buildup are a concern.
- Full Foam (222000) — Standard closed-cell foam padding. Provides more cushioning and warmth. Preferred in cooler environments or when additional padding is needed.
- 3XL Full Foam (222050) — Full Foam construction in an extended size for leg circumferences up to 38".
Size & Fit Guide
The Exoform uses a Slide-to-Size system — one brace adjusts to fit a range of leg sizes. Confirm your leg inseam and circumference before ordering.
| Option | Leg Circumference | Leg Inseam | Part Number |
|---|---|---|---|
| Cool Foam | Up to 28" Up to 71 cm |
18" – 24" 46 – 61 cm |
222100 |
