What is the Donjoy Reaction Knee Brace?

The Donjoy Reaction Knee brace was developed by an orthopedic surgeon for patients who suffer with Anterior knee pain related to a range of conditions including:

  • Chondromalacia Patella
  • Osgood-Schlatter disease
  • Quadriceps and Patella Tendonitis/Tendinosis
  • Mild Osteoarthritis (OA)
  • Patellofemoral (PF) Syndrome tracking issues

The Reaction Knee Brace features an elastomeric web design, which provides energy dispersion and shock absorption for progressive pain relief. The brace has adjustable straps which stay in place and they can also be customised for comfort and desired degree of elastic return.

When can I use the Reaction Knee Brace?

The Reaction Knee Brace can be used to relieve Anterior knee pain during daily and sporting activities including contact sports. It can also be used following a Cartilage injury or when there is mild Arthritis in the knee. The knee support features a removable anti-sweat breathable sleeve that is worn beneath the brace helping to provide compression and tissue containment, a characteristic which can also be used to help protect the skin from chafing and irritation, improving the users overall comfort.

How does the Reaction Knee Brace work?

The Reaction Knee Brace features flexible membranes, which elongate with joint motion and return to their original dimensions, absorbing shock and moving peak loads away from the painful area. The knee brace provides an unrestricted, intimate fit around the patella and the mesh backing is both comfortable and breathable. This innovative design acts dynamically to stabilise the patella by improving tracking and reducing the associated pain while dispersing energy across the knee. The web design offers a stylish solution to your knee problems by absorbing shock, shifting the load away and dispersing energy across the knee. It also features dual-axis hinges which are flexible and provide additional support to the knee. Indeed recent research carried out by the University of Central Lancashire (UCLAN) has concluded that the Donjoy Reaction Knee Brace 'significantly reduces pain' in Patellofemoral Pain Syndrome (PFPS) patients giving them a sense of improved knee stability during functional task. These changes are clinically relevant and most likely a consequence of altered lower limb biomechanics due to an improvement in movement control at the knee.

Please note: The Reaction Knee Brace is provided with a sleeve for those with ample leg hair though using this feature will dramatically impact the benefits of the knee brace.

What size is the Reaction Knee Brace?

Take the measurement of your thigh 6" above your kneecap using a flexible type tape measure. Use the diameter to choose your size. If you are between sizes, please choose the larger size.

  • XS/SM 33cm - 47cm (13" - 18.5")

  • XL/XXL 60cm - 75cm (23.5" - 29.5")

“knee brace lives up to expectations (so far)”

Reviewed by Anonymous

This knee brace was recommended by my Physio. Have only used it twice so far but it certainly makes my knee feel stronger. The brace itself was exactly what I expected from the description online. Delivery was very quick.

“Works as advertised”

Reviewed by Anonymous

With severe patellofemoral damage after the trauma of a patella fracture 14 years ago, I've been looking for an alternative to taking large amounts of prescription killers. This brace does alleviate alot of pain and has allowed me to cut down on analgesics. It doesn't fix your knee but it does allow you to function and not then suffer the consequences with pain because of over-use.

Also I ordered the product 11am on a Friday and it was delivered 10am on Saturday. Fantastic service !

“Good quality knee brace BUT...”

Reviewed by Gavin

When i bought this brace it came with a knee sleeve to wear under the brace. At first it was very comfortable. But as i got the strength back in my knee and the quad muscles started to grow back to normal size the knee sleeve became far too tight as there is not much stretch in the elastic. I tried to order a bigger size sleeve from this site but they dont sell this sleeve seperatley. I priced other sleeves and they want approx £40! I think if they are going to sell this brace then surely they should sell a replacement sleeve for this particular brace. The brace itself however is very good. I have used it in judo, wich was ideal as there are no big bulky hinges to get in the way. It is also very comfortable to wear all day.

“Hoping I can delay knee surgery”

Reviewed by Anonymous

The reaction knee brace has given me the opportunity to continue with my hobby of rambling. I am aware I will need a replacement knee in the near future but the brace I hope will delay the need for surgery.

“A very useful product with proven benefits - Ray Merrell”

Reviewed by Ray Merrell

At last a brace that fully replicates the action of the knee whilst actively playing sport (in my case tennis) the plastc weblike membrace seems to compensate for my ligament weakness and gives me more confidence to make quick adjustmennts that are neccessary during play. It seems to be a quality product and I hope it is as durable as it looks.. I would recommend it to amyone who has knee problems and wishes for more mobility in action.
