Product descriptions for knee braces are full of terms like "side stabilisers", "patella gel pad" and "open patella design". If you are not sure what these features actually do, it is hard to tell whether a brace is right for you. This guide explains the most common knee brace features in plain English, so you can understand what you are buying and what to expect.
A quick guide to how a knee brace supports the knee
The knee is a hinge-like joint that mainly bends and straightens, but it also has to cope with twisting and sideways forces, especially in sport. Different brace features focus on different things: some help limit unwanted side-to-side movement, some cushion the area around the kneecap, and some provide compression and a snug fit. Most braces combine several of these.
What are side stabilisers on a knee brace?
Side stabilisers are supports built into the inner and outer sides of a brace, running vertically alongside the knee joint. Depending on the design, they may be flexible springs, plastic stays or rigid hinges.
What do side stabilisers do?
- Help control side-to-side movement. They add structure along the sides of the knee, which can give a greater sense of stability during sideways movements.
- Help the brace keep its shape. Stabilisers stop the fabric bunching or rolling, so the brace stays where it should.
- Add confidence. Many people with knees that feel unsteady, or who are returning to activity, like the reassuring feel of extra structure.
Flexible stabilisers versus hinges
Flexible stabilisers, such as spring stays, bend with the knee and are common in everyday and sports braces. They offer more structure than a plain sleeve while still allowing natural movement. Hinged braces use mechanical joints and are typically used for more significant ligament injuries or after surgery, usually on the advice of a clinician.
The Venollo knee brace uses flexible, double-sided spring stabilisers, two on each side, designed to support the knee while letting it bend through everyday and sporting movement.
What is a patella gel pad?
The patella is your kneecap. A patella gel pad, sometimes called a gel ring or buttress, is a cushioned ring that sits around the kneecap inside an opening at the front of the brace.
What does a patella gel pad do?
- Cushions the area around the kneecap, spreading pressure for a more comfortable feel.
- Helps keep the kneecap area supported as the knee bends and straightens.
- Acts as a fitting guide. Centring the ring around your kneecap is the easiest way to position a brace correctly.
Why is there a hole at the front of some knee braces?
This is called an open patella design. The opening avoids putting direct pressure on the kneecap itself, while the surrounding ring supports the area around it. Many people find this more comfortable, particularly when bending the knee.
Other features to look for
Adjustable straps
Hook-and-loop straps let you tighten or loosen the brace to suit your leg and activity. They are what make one-size, adjustable braces possible. See our guide on how to put on a knee brace for the right fastening order.
Anti-slip strips
Silicone strips on the inside of a brace grip the skin lightly to help stop it sliding down during movement.
Breathable materials and ventilation
Neoprene and similar fabrics provide warmth and compression. Ventilation holes and moisture-wicking linings help manage heat and sweat during longer wear.
Who might choose a brace with these features?
A brace combining side stabilisers and a patella gel pad sits in the middle of the support range: more structured than a simple sleeve, but more flexible than a hinged brace. People often choose this style for:
- Knees that feel unstable or prone to "giving way"
- Discomfort around the front of the knee during activity
- Extra support while returning to sport after a minor knee strain
- Everyday support for active days, work or long periods on their feet
If you have a specific injury or diagnosis, a GP or physiotherapist can tell you whether this type of brace is appropriate. Read our guides on choosing a knee brace for sport and knee support for work for more on matching support to your activities.
Frequently asked questions
Are side stabilisers uncomfortable?
Flexible stabilisers are designed to bend with the knee. If they dig in, the brace may be twisted or fitted too tightly. Re-centre it and check the stabilisers sit evenly on each side of the knee.
Does a patella gel pad fix kneecap problems?
No brace can promise to fix a knee problem. A gel ring is designed to cushion and support the area around the kneecap for comfort. If you have ongoing kneecap pain, speak to a healthcare professional.
Can I wash a brace with stabilisers and a gel pad?
Follow the care instructions supplied with your brace. Our guide on how to wash a knee brace covers gentle cleaning and drying.
