Please note that this knee brace can be worn on either the left or right leg.

Which Size Do I Need?

The Donjoy Reaction Knee Brace is available in four sizes. To find out which size you require, please measure the circumference of your thigh 15cm (6 inches) above the centre of your kneecap as shown in the diagram, then refer to the sizing table below.

How to measure thigh circumference
Measure 15cm above the centre of the kneecap as shown

Size Thigh Circumference (cm)
Extra Small / Small 33 - 46cm
Medium / Large 47 - 59cm
Extra Large / XX-Large 60 - 75cm
XXX-Large Over 75cm

Our Sizing Tips

  • For measurements that fall between two sizes, we recommend choosing the larger size for a greater level of comfort
  • The brace is mean to compressive and so will feel tight; if you would prefer less tightness, please choose a larger size
  • If you do not have a flexible tape measure, take your measurement with a piece of string, then measure the string with a ruler
  • Please take into account any joint swelling before selecting your size

Indications for the Donjoy Reaction Support

The Donjoy Reaction Knee Brace is designed for general anterior knee pain, i.e. pain on or around the knee cap. This pain is often associated with the following conditions:

  • Chondromalacia patella
  • General anterior knee pain
  • Osgood-Schlatter disease
  • Patella osteoarthritis or mild bicompartmental osteoarthritis
  • Quadriceps and patella tendonitis or tendinosis

Key Features and Benefits

  • Elastomeric web design reduces pain by dispersing energy across the knee
  • Flexible membranes absorb shock and shift peak loads away from painful areas
  • Contoured fit, compression and stretch of the membranes increase proprioception
  • Webbed design dynamically stabilises the patella on all sides
  • Features dual axis hinges for additional support
  • Supplied with an under sleeve for improved comfort
  • Open framework design provides an intimate fit around the patella
  • Mesh backing is highly breathable for additional comfort
  • Dual-axis hinges wok in concert with the elastomeric web for extra stability
  • Adjustable straps help the brace remain in place during daily or sporting activities

How Does the Brace Work?

The external webbing (or elastic exoskeleton) of the Donjoy Reaction Knee Brace dampens impact forces experienced by the knee joint and disperses this energy across the knee. This helps reduce shock targeted in a specific area. The support is also fitted with an under sleeve so you remain as comfortable as possible.

What's the Benefit of a Webbed Design?

The unique open-framework design of the Reaction Knee Brace isn't just for a sporty aesthetic, it also provides a refreshing breathability that no other knee brace can match. The webbing is designed work like a high-tech spring that boosts the power of your knees, while also allowing fresh air to cool the skin during intense physical exercise.

Find Out More About the Reaction Knee Brace

Learn more about the Donjoy Reaction Support by watching the video below. The support allows you to walk or run with your full range of motion, allowing you to continue performing the activities you enjoy.

Is This Support Suitable for Watersports?

This support can assist with the impacts and pain associated with water sports, but if it is used in salt water, it should be rinsed with clean water after each use. It should then be dried, as some components of the brace may wear over time if left waterlogged.

Supplied with an Undersleeve

To maximise your comfort levels, the Donjoy Reaction Web Brace comes supplied with a nylon-spandex undersleeve that prevents the brace from rubbing unfavourably against your leg. Just as breathable and stretchy as the brace itself, this undersleeve provides added protection warmth and comfort without impeding movement.

Available in Three Colours

This techy-looking sports brace is available in three slick colours for you to choose your favourite, whether its a steely grey, flame red or royal blue. To choose your preferred colour, select it from the drop down menu at the top of this page before you purchase.
