DonJoy Reaction WEB Knee Brace

The Ultimate Support for Knee Pain

The Reaction WEB Knee Brace is ideal for anybody suffering with knee pain. Developed by an orthopedic surgeon, the Reaction WEB Knee Brace features an innovating webbing design much different than average sleeve-like braces. Its elasticity and flexible hinges work together to provide stability for the knee by absorbing shock and shifting weight away from the painful area. Best of all, it's breathable and comfortable.

For active individuals who want to stay moving despite having knee pain, the Reaction WEB Knee Brace is your ticket to comfortable support during your activities such as walking, gardening, running, hiking, soccer, basketball, tennis, and so much more.

The Best Solution for Knee Pain

Progressive Pain Relief

The elastomeric web design helps to reduce pain by dispersing energy across the knee. The web acts like a spring to absorb shock and shifts the peak loads away from the painful area of the knee.

Elastomeric Web

Acts to dynamically stabilize the patella on all sides, bringing the patella into proper tracking position to reduce pain for patients with general patellofemoral instabilities.

Sustained Comfort

The open framework of the elastomeric web, in combination with the mesh backing, creates a comfortable fit and a breathable solution for relief of anterior knee pain.

Can be used for:

  • Patellofemoral pain syndrome or chondromalacia patella (runner's knee).
  • Quadriceps or patellar tendonitis/tendinosis (jumper's knee).
  • Osgood-Schlatter disease
  • General patellofemoral tracking issues
  • Mild knee osteoarthritis

Product Description

The DonJoy Reaction WEB Knee Brace uses a responsive, webbed approach to knee pain that gives you a distinct alternative to the basic knee sleeve. Developed by world renowned orthopedic surgeon, Dr. William Nordt, the DonJoy Reaction WEB can help decrease knee pain and increase function, getting you back to your active lifestyle. The elastomeric web is an innovative solution that absorbs shock, disperses energy and shifts pain away from your knee. This webbing acts to dynamically stabilize the patella (kneecap) on all sides, bringing the patella into proper tracking position to reduce pain. The open framework of the elastomeric web, in combination with the mesh backing, creates a comfortable fit and a breathable solution for relief of anterior knee pain. It's secured with Velcro straps, and weighs only 0.5 lbs. The lightweight design makes this knee brace ideal for all-day use. One undersleeve is included, and is made of 85% nylon/15% spandex. The DonJoy Reaction WEB can be used to treat or prevent the following knee injuries: patellofemoral pain syndrome (PFPS), chondromalacia patella (runner’s knee), quadriceps or patellar tendonitis/tendinosis (jumper’s knee), Osgood-Schlatter disease, general patellar tracking issues and instability, and mild knee osteoarthritis. The DonJoy Reaction WEB is worn by professional snowboarders, volleyball, football players; as well as the U.S. Snowboarding and U.S. Ski teams. Universal fit allows the DonJoy Reaction WEB Knee Brace to be worn on either the left or the right leg.

75 customers mention19 positive56 negative

Customers are dissatisfied with the flexibility of the knee brace. They mention that the silicone webbing flexes too much, and the overall product is too stiff.

PROS:• Keeps the Kneecap in Place (better than other braces in my opinion)• Easy to Remove & Tighten - Only Four (4) Velcro Straps• Separate Cloth Sleeve Cover for knee/leg to aid in comfort (and to prevent slippage?)• Material - Rubber+Cloth Material. No Real Metal makes this brace pretty comfortable to wear.• Reputable Brand “DonJoy” = extensive line of durable medical productsCONS:• BROKE within ONE (1) week of receipt & use the Rubber Webbing Broke (only slightly, but imho indicated more to come)• Materials = Non-Metal+Rubber = Not very good for Long Term durability• TOO MUCH MOVEMENT - Range of Motion - Non-Metal Joints on Each Side of Knee allow too much range of motion and not enough ‘sturdy’ structural support.• SLIPPAGE - Brace tends to Slip Up/Down during light movement (standing/walking) = Note: I was using a Size S/XS so smallest available size!• REPLACEMENT/REFUND “Process” Extensive (Frustrating)- MUST be Returned for either a Replacement or Refund (Photos, Multiple Emails, Printing Label, Repackaging+Arrange Pick-Up or Drop at Drop box) = seems a LOT for an item I received in just a white plastic envelope without any packaging material.After suffering a patella track issue, I purchased a DonJoy Web Knee Support brace. Initially, I loved this brace, but during the 1st week my brace webbing broke (see photos), which was very disappointing and speaks of its lack of long-term reliability.The brace webbing seems unique to this DonJoy product. I found that the webbing offers a unique amount of support that feels as if it is much more efficient at keeping One’s kneecap/patella in place compared to other braces.This brace also offers the same common support as other braces, with the two (2) joint supporting ‘struts’ {?- not sure of their proper name} on each side of the knee. However, unlike many other side supports, this brace’s side supports are NOT metal, but made of plastic. I felt that the plastic supports seem to bulge out sideways whenever I bent my knee, which I didn’t like. I think the brace would be much better if the supports were metal and better limited the overall motion of the knee.This brace also includes a slip over the leg/knee cloth nylon? sleeve, used to offer a bit of compression possibly (not enough to be uncomfortable or really qualify as compression), but definitely helps maintain the webbing portion’s location, so it does not slide up or down, both of which I experienced while wearing the brace.I found I would end up tightening the brace when sitting and my knee was bent, and then that this brace would slip up or down when I would stand or I actively moved (I walked, not like I was doing anything athletic).While this brace is good compared to others so far as a kneecap/patella track issue (kneecap popping out of track). I do not think I would recommend this brace if looking for general knee support or a brace to limit knee morion. Also, I believe it is extremely Important the sizing is correct, and I would go so far as to recommend that you contact a local prosthetic or durable medical equipment company to see if they sell this device and ask them to measure you in person for it. You can always take those measurements or the size they tell you and then order the brace here on Amazon or wherever.POST SALES SUPPORTNote: I would be more understanding of the extensive “process” if I were filing months later. My issue was within the 1st week!SELLER: (Via E-mail):When I contacted Motion Store, the Seller, I was told they would be happy to process a replacement. However, after multiple emails, my taking requested photos attached. I now have to send the brace back for them to even replace the device, ridiculous! So, do NOT count on post sales support without jumping through multiple hoops! Being down sick w/a cold+on one foot (I deep sprained my ankle so in a different DonJoy (MaxTrax foot boot). So, I decided I was done with the whole pain the bum situation at this point. But, if I return this product, it won’t be for a replacement. It will now be for a full refund (& I won’t buy another DonJoy product ever!) I will update later if I go forward with the refund “process”.MANUFACTURER: (Via Phone)Spoke to DonJoy the brace Manufacturer. For Replacement or Refund, expect to be required that You provide photos, wait for a Return Request to be processed and You MUST return the product, They will provide a shipping label for the return if approved.Tip/My opinion: This item is considered “Durable Medical Equipment (DME)” by Insurance Companies, and should be covered by most Health Ins.Co’s fully or at a percentage. It’s worth a shot to call and ask them before paying for it yourself. May need Your Primary Doctor to order for you, but would be Free! Plus, If thru a local distributor then any return/replacement would be a heck of a lot easier!!
