A knee immobilizer is a type of orthopedic brace designed to keep the knee joint in a fixed, straight position (extension) to prevent movement. It is mainly used after knee injuries, surgeries, or in cases where the joint needs stabilization and protection during the healing process. Unlike functional knee braces, a knee immobilizer does not allow bending—it’s meant purely for immobilization.
Features of a Knee Immobilizer
- Rigid Support
- Has metal or plastic stays (bars/rods) on the sides to keep the leg straight.
- Prevents knee flexion and extension.
- Adjustable Straps
- Velcro straps along the length of the brace allow for secure and customizable fitting.
- Straps ensure the immobilizer doesn’t slip and provides consistent support.
- Padding for Comfort
- Made with soft foam or padded fabric for patient comfort.
- Breathable material helps reduce sweating and irritation.
- Universal Fit / Multiple Sizes
- Available in different lengths (usually 14–24 inches) to fit different leg sizes.
- Some models are adjustable to accommodate swelling.
- Open Patella Design (in some models)
- An opening around the kneecap for pressure relief, ventilation, and correct positioning.
- Lightweight Construction
- Despite having rigid stays, most are lightweight for easy wear and mobility on crutches.
- Easy Application & Removal
- Designed for quick wearing and removal without medical tools, even at home.
- Non-Slip Lining (in some types)
- Keeps the immobilizer from sliding down during walking or standing.
