Benefits

Protects your knee during healing by limiting harmful bending and hyperextension while allowing safe, guided movement
Restores stability and confidence for walking, standing, and daily activities after injury or surgery
Supports controlled recovery with adjustable range-of-motion settings tailored to your provider’s recommendations

Provides firm, medical-grade support without fully immobilizing the knee to allow mobility
Designed for all-day wear, combining lightweight construction with breathable padding for comfort

Why This Hinged Immobilizer Knee Brace Works

This brace uses adjustable hinges and secure straps to stabilize the knee and control its range of motion, helping protect the joint while allowing safe, guided movement during recovery.

Controls knee movement where it matters most
The hinged design allows you to set precise limits on bending (flexion) and straightening (extension), helping prevent movements that could stress a healing knee.
Stabilizes the joint with dual side hinges
Rigid hinges on both sides of the knee help keep the joint aligned, reducing unwanted side-to-side motion during walking or standing.
Applies consistent support through adjustable straps
Multiple straps secure the brace evenly around the leg, improving stability while maintaining comfort throughout the day
Guides safe movement instead of fully locking the knee
The brace allows controlled motion, which supports functional movement and rehabilitation rather than complete immobilization.
Helps reduce strain during daily activity
By supporting proper knee positioning, the brace helps offload stress from injured or post-surgical tissues during routine movements.
The controlled Range of Motion (ROM) has 12 Flexion Positions ( 0°, 120°) and 10 Extension Positions 0°, 90°). This design helps to limit and prevent hyperextension and flexion of the knee.

What our customers say.

Yang L,

“Comfortable support for Post OP"

My son underwent knee replacement surgery and needed a reliable hinged brace. He is in college playing lacrosse. This hinged knee brace is comfortable with padding and easy to adjust. Now I am not worried as he is confidently moving around with good support

“Worth every penny.”

I tore my patella tendon and needed an immobilizer knee brace. They gave me an almost similar brace at the ortho's office, but it was too bulky and heavy on my foot. It felt like I was dragging a house with each step. This exceeded my expectations and also impressed the ortho. The built is very lightweight, sturdy, and did the same function much better, and it was 1/3 of the price..amazing.

“Do not need surgery afterall”

I used to feel a sharp pain when I extended my knee to a certain angle. I would forget only to feel a sharp, unbearable pain. The pain was so intense I would feel my knee get hot. When I bought this brace, I adjusted it below that extension angle. I haven't had any pain in a long time. I don't think I need the surgery as previously suggested.

How tight should it feel?

The brace should be snug but not so tight that it restricts circulation or causes numbness. You should still be able to move as instructed without discomfort.
