Product Details

Product Description

Reduces anterior knee pain by dispersing energy across the knee.

The DonJoy Reaction knee brace utilizes an elastomeric web design, which absorbs shock and shifts the peak loads away from the painful area of the knee. This dispersion of energy helps reduce the anterior knee pain you suffer from.

Another advantage of the elastomeric web is it dynamically stabilizes the patella on all sides, thus bringing the patella into proper tracking position to reduce pain caused by general patellofemoral instabilities.

The DonJoy Reaction knee brace is extremely comfortable to wear because the open framework of the elastomeric web and mesh backing makes the brace breathable, unlike the traditional elastic and neoprene sleeves.

The DonJoy Reaction knee brace is used to treat or prevent the following injuries:

  • Chondromalacia patella
  • Quadriceps or patellar tendonitis/tendinosis
  • Osgood-Schlatter disease
  • General patellofemoral tracking issues
  • Mild OA

Product Features...and the benefits you'll experience!

  • Progressive Pain Relief
    The web absorbs shock and shifts the peak loads away from the painful area of the knee and stabilizes the patella on all sides to ensure proper tracking position.
  • Sustained Comfort
    The open framework and mesh backing makes this brace breathable and comfortable during use.
  • Dual-Axis Hinges
    These hinges are flexible and work in conjunction with the elastomeric web for optimal fit and support, and providing energy dispersion to the knee.
  • Undersleeve Included with Purchase. Made with 85% Nylon and 15% Spandex

Sizes: Available in sizes: XS/S, M/L, and XL/XXL and XXXL. Click on Size Chart tab above for sizing info.

    • I have an runners knee they call it and hyper mobility in my knee and want to start swimming again ,but every time I try it feels like my knee cup is jumping out would this knee support help stopping it
    • Hi Yvonne,

      The DonJoy Reaction web knee brace would be suitable for your condition
  • Lucy at 25/01/2017 07:53
    • Hi I measured my leg as instructed and it came back with the small size for this brace. I received them and they are very tight. There is little spare Velcro on the straps when they are done up. I just wondered if this is the expected fit as like I said I double checked my measurement and I'm definitely a small.
    • Hi Lucy,

      We would suggest to return this brace for the next size up.
  • Phil Turner at 01/06/2014 06:55
    • I am a strong skier and retired pro ski patroller 69 years old, I still have good joint space between the 2 bones but bone to bone femer to knee cap. I am getting some arthritis in the left knee.Lots of pain now skiing under the knee cap and when getting up from sitting position and walking down stairs. Would the reaction brace help this pain, especially skiing? Thanks
    • Phil
      This would be a good brace for you to use to help with that pain under your kneecap. The brace was design for someone like you in mind, to help absorb the shock that your knee gets and transmit the force throughout the muscles of the leg instead of right at your kneecap. We also have a variety of other braces specific to skiing that may help you continue to stay on the slopes if you want more options.
  • Lavita at 13/05/2014 03:55
    • I have broken my patella and am in need of a brace. It's 4 weeks post injury and doctor gave no recommendations regarding type. This one looks appropriate for my knee. I can't have anything touch it as it is still tender, bruised, swollen and painful. Is this the correct brace for me? How quick is shipping?
    • Thank you for your question. Yes, this Reaction WEB brace would be appropriate.
  • Brian at 27/04/2014 18:49
    • I have lateral knee pain, and stiffness after running or walking. I have a complex lateral meniscus tear, and also, ITBS. What would be the best brace for me? I gather that since I have no anterior knee pain, this brace would NOT be a good choice.
    • The Reaction may not be the best choice. For the ITB syndrome a knee strap could help such as the DonJoy Cross Strap. But the ITB could be caused by abnormal patella tracking, so you could try the Lateral J Patella Knee Brace. The brace has a lateral buttress around the knee and a strap to pull the kneecap into the correct position. You can also get the brace with hinges to help with general stabilization of the knee.
  • Al at 17/04/2014 17:09
    • I have had a knee replacement and my new knee skis well. I am wondering if this brace might help make the replacement last longer. I currently do not use a brace of any kind when I ski.
    • Al
      The Reaction Knee Brace is indicated for those who suffer from anterior knee pain. It is used by a lot of skiers for that reason. We do have rigid knee braces that will protect the knee from injury while skiing but no brace will make a knee replacement last longer.
  • Howard at 23/03/2014 19:10
    • I bowl 3 times a week. I have had my left knee replaced and my right knee needs it. I need to stabilize my knee when I bowl. I don't think I need to protect it from further injury. I just need to keep pressure on both knees, it relieves the pain in the right knee and the "loose" feeling in the bionic knee. Is the reaction brace a good solution for my problems?
    • Howard
      If you feel like you have pain in the front of your knee when bowling, then this would be a good brace for you. If you feel your knee is unstable as a whole, I would suggest the DonJoy Economy Hinged Knee Brace: https://www.betterbraces.co.uk/donjoy-economy-hinged-knee The bilateral hinges will give your knee the much needed support.
  • Deb at 10/03/2014 23:26
    • Have had torn meniscus repair in left knee dow.n twice, I am a 60 year old female who started running about 4 years ago and got up to the half marathon distance. Hoping to continue again but the doc says I am almost bone on bone. Before the surgery he sad I should be back to running in about 6 weeks after surgery, then it was 2 months, then 3 months, now it is a well we can try a few things up to a knee replacement, (I am not ready for this). He did not suggest a knee brace of any sort. He suggests swimming and cycling, I like to cycle and hate swimming. I want to run. What would you suggest?

    • Thank You for your question. If most of your pain is centered around the knee cap and in the area the Reaction WEB brace covers, this would be a great brace for you. If the knee pain is more medial/lateral (on the sides) or deep inside the knee joint you may look at the DonJoy Deluxe Hinged Knee or the DonJoy economy Hinged Knee.
  • Fed at 09/03/2014 04:56
    • hi
      i have cartilage lose due to a meniscus injury not treated properly, i practice wakeboard and although i dont feel too much pain, sometimes i feel pain on the back of my knee... would this brace help for my situation and is it good for wakeboarding? had a cti in the past but wasnt a very good experience...
      what would you recommend? thank you!
    • Fed
      The Reaction knee brace is a good substitution for a knee sleeve, which is what I would reccomend for womeone with a meniscus injury. The Reaction will not hlp the pain in the back of your knee though. this brace is indicated for those who have anterior knee pain. The pain you experience behind your knee could be the meniscus, but this brace would still be better than a regular sleeve. and better in the water
  • Dale at 03/03/2014 05:45
  • Bill at 02/03/2014 22:19
    • I had a TKR over two years ago. Have seen 9 different Doctors about the continuing pain and stiffness in the knee but no one can tell me what is wrong. Have had every test that can be done any none of them can see anything wrong with the knee replacement nor the soft tissue. I wear a compression brace that is I would say mild support and it helps. I am 62 and love to walk and play golf but have a little difficulty doing both because of the pain. Would you suggest one of your braces? Hurst when I twist it. Thanks
    • Bill
      If wearing a sleeve helps relieve your pain a little , the Reaction May help more. It is indicated for those that suffer from anterior knee pain and is a better substitute than a sleeve
  • Dennis Freeze at 13/02/2014 08:42
    • I suffered a complete quadriceps rupture, with surgical reattachment. I have no lateral instability, but the knee wants to buckle (suddenly) occasionally. My doctor thinks it's from slow-healing nerve damage. Other than the buckling, my knee is pretty strong except end-range stuff (still can't walk down stairs properly).

      I need to start exercising again, and I'm concerned that the buckling could happen at the wrong time while moving. It's always a momentary thing, and then it catches hold again. I'm afraid if I'm moving around more, I might not be able to catch myself in time.

      Will this brace work? Will the hinges slow down any sudden buckling of the knee?
    • Dennis
      The hinges on this brace are not that supportive. If you have pain in the front of your knee while walking up and down stairs this brace can help decrease that pain. If you would like more stability with hinges I would suggest the Economy hinged knee brace. https://www.betterbraces.co.uk/donjoy-economy-hinged-knee. This brace has metal hinges that would protect better than the Reaction brace
  • Kelli at 09/02/2014 18:13
    • I have chondromalacia due to alignment issues and have very little cartilage in my right knee. I have been very inactive for the past few years due to the pain I feel doing common things like walking and climbing stairs at home and at work and even from sitting. I am looking for a knee brace that I can wear all the time that fits under clothes and is comfortable and will allow me to return to the active lifestyle I used to have before this all became such a huge issue. Will this knee brace help? Or is there a better one that you can recommend?
    • Kelli
      The Reaction knee brace si the brace that i would suggest for the isuues that you are having with your knee. The brace is indicated for thoses with anterior knee pain due to chondromalacia
  • Kyle at 09/02/2014 05:00
    • I work for a company that requires me to do many stairs with added weight (1-45lbs). What brace would be best for preventing the added stress that my knees will be under due to the impact caused by the added weight?
    • Kyle
      The Reaction Knee brace would work well if you get pain going up and down stairs by dispearsing that force on you knee into the elastomeric web of the brace.
  • Stephen at 28/01/2014 21:29
    • Hello,

      I play catcher for my baseball team and my knees have been hurting for as long as i can remember. And I was wondering if this knee brace would be ideal for playing the catcher position e.g. staying in the crouching position for long periods of time, and running a lot.
    • Thank you for your question. This Reaction WEB Knee brace is designed for knee pain in the front of the knee. If your knee pain is on the sides or the back of the knee you may want to consider a sleeve for compression or a hinged knee brace that will offer support to the medial and lateral sides of the knee. If you have questions please feel free to call product support at 888-405-3251.
  • Alisha at 19/01/2014 20:52
    • I dislocated my left about 8 years ago. Ever since when I do activities I notice that it wants to slip occasionally. I will also get occasion pain behind my knee. I am about to start playing indoor soccer and since I am using my legs for kicking and running etc I really feel that I should have a brace for my knee. I am trying to decide which would be the best fit: Reaction, Tru-Pull Lite, or Tru-Pull advanced.

      I have used a variety of knee braces in the past and they always seem too tight on my patella and very uncomfortable.

      Thanks for the help.
    • Hello,

      I recommend the Tru-pull lite for patella dislocations. This brace is 9" in length and has a buttress that sits right up against the patella to prevent dislocations.

      If you would also like a hinge in the brace take a look at the Lateral J Brace. This provides patella support and has the option to add a hinge.

      Thanks for Contacting Donjoy.
  • Sarah at 18/01/2014 16:05
    • I had a patella subluxation and grade one MCL tear this fall, would this be the best brace for those injuries. 11 years ago I did the same to the other knee requiring surgery to help with the patella tracking, I really don't want to go through that again.
    • Sarah
      The Reaction knee brace is for those who suffer from anterior knee pain associated with patellar tendonitis, and other patellar femoral problems. I would suggest either the Playmaker II with a patellar donut https://www.betterbraces.co.uk/donjoy-playmaker-ii-knee-brace-1 or the DonJoy Drytex Hinged Air Knee brace https://www.betterbraces.co.uk/donjoy-drytex-hinged-air-knee-brace
  • tom at 12/01/2014 16:09
    • I have pain in my left knee. I had orthscopic surgery to remove cartilage about 30 years ago. The orthopedic doctor told me the pain is due to severe arthritis, bone-on-bone iritation, and alignment issues (my thigh bone comes in at a slight angle ).

      I am active and can have pain due to being on my feet for long periods of time. I also ski and have pain while skiing and swelling afterwards.

      Would the Reaction WEB Knee brace be a good choice to relieve the pain I'm experiencing?
    • Tom
      You have severe arthritis and the Reaction Knee Brace is not the brace for you. You need to look at either the donJoy Defiance witha OA hinge or the DonJoy OA Adjuster 3
      https://www.betterbraces.co.uk/donjoy-defiance-iii-custom-knee-brace https://www.betterbraces.co.uk/donjoy-oa-adjuster-3-knee-brace
      These braces are for moderate to severe OA. It sounds as if you have lateral compartment arthritis, but you should make sure with your physician before purchasing anything.
  • Nick at 07/01/2014 23:16
    • Out of the performer, lateral J, and Reaction knee braces which do you prefer? I plan to play basketball in this brace and recently had surgery on a broken tibia and torn patella tendon. I experience pain in the front of my knee and occasionally to the sides.
    • Nick
      The Reaction Knee Brace is best for your pain.
  • Aaron at 06/01/2014 21:01
    • i play basketball and i was diagnosed with patellar tendonitis

      i have tried several braces but do not work or are not comfortable.

      will this work for me playing basketball?
    • Aaron
      The Reaction is designed for those who suffer anterior knee pain caused by patellar tendonitis and other patello femoral disorders. This brace should help you when you play basketball
  • lexi at 04/01/2014 17:05
    • i horse back ride and have patellar tendonitis in my left knee. i am also looking into a everyday brace but this would specifically be for horseback riding. do you think this will work? The issue i have had with braces in the past involve pinching behind the knees and not fitting under my boots or damaging my saddle. I do need a support brace. would this brace work?
    • Lexi
      The Reaction brace should work well for you. It is not made of metal so it should not afect your sadle. There is a opening in the back of the brace so there should not be any irritation behind you leg.
  • SageLenea at 19/12/2013 21:58
    • Hello,
      I torn my MCL about 3 years ago. And re injured it about a year ago. Ever since, I have had a lot of pain, mostly with walking and bending. I usually do better with a generic brace, but it eventually bothers the back of my knee (fabric build up) usually due to squatting. Would this brace be a good option for me?
    • Sagel
      The reaction Knee brace will not help support a knee with a MCL sprain. You need a brace that has metal hinges on the side. We have a variety to choose from and you can get them with a hole in the back of the brace so you will not get the bunching of fabric behinde the knee. The DonJoy Deluxe Hinged Knee is a good brace for you and you can get it with a open popliteal which is the opening in the back of the brace. Let us know if you have any other questions

  • Stuart Paynter at 25/11/2013 00:49
    • My son is an elite skier and has suffered a bone bruise on the top of the tibia which is taking a long time to heal. He still has issues with impact activities like running and jumping and previously had a long bout of O-S. Would the brace help alleviate some of the impact while he recovers?
    • Stuart
      Thank you for contacting product support. The reaction knee brace is for those who suffer from anterior knee pain cause by patellar problems. I don't think this will help your son. A hinged knee brace would most likely be the best possibly the Deluxe Hinged Knee Brace located here: https://www.betterbraces.co.uk/donjoy-drytex-neoprene-deluxe-hinged-knee-wraparound-sleeve
      Another option if your son has pain on one side of his knee is the OA Lite https://www.betterbraces.co.uk/donjoy-oa-lite-osteoarthritis-knee-brace This brace has a single upright hinge located on the opposite side of the painful side. The hinge helps to unload the side that hurts.Take a look and if you have any other questions please let us know
  • Angel at 25/11/2013 00:25
    • Will this brace help with meniscus problems? My son is a goalie on a hockey team and needs to wear the brace underneath his goalie pads with little interference and feel
    • Angel
      Thank you for contacting product support. The Reaction knee brace is ideal for anyone who has anterior knee pain associated with patellofemoral problems, ie. kneecap problems. It is not really indicated for meniscus tears. I would suggest the DonJoy Cartilage Knee Sleeve brace here: https://www.betterbraces.co.uk/donjoy-cartilage-knee-sleeve-brace This sleeve is indicated for meniscus tears and can easily go under hockey equipment.
  • Allison MacCormick at 20/11/2013 20:48
    • Hi
      My 14 yr old daughter has patella tracking issues and her knee/leg buckles. She was given the Lateral J Patella brace a couple of years ago. It has been great until now. She plays ice hockey and she has a a couple of incidents in the past 2 weeks where her kneecap has moved while she was playing (and wearing the brace). I am looking to see if there is another brace that might provide more support for her. Any suggestions?
      Thank you
    • Allison
      Thank you for contacting product support. For someone who has patella tracking problems, take a look at the Tru-Pull Advanced System Knee Brace https://www.betterbraces.co.uk/donjoy-tru-pull-advanced-system-1. This brace has a buttress on the outside of the knee that can be pulled across the knee so it allows the wearer to apply as much presser as needed to support the kneecap
  • Gordon Petrie at 10/11/2013 23:43
    • My knee condition is a repaired ACL with medial OA issues (which is my main problem). I have a custom Defiance III and it works great. I am wondering if the reaction will be a more light weight and slimmer design that will help offload the medial cartilage. I am looking for a brace that can better fit under a wetsuit than the defiance III and give me partial protection
    • Gordon
      Thank you for contacting product support. The Reaction knee brace was designed for individuals who suffer from anterior knee pain, patellof femoral disorders and mild OA. It will not support your ACL or unload the medial compartment of your knee. The Defiance is the best brace for you.
  • 2e at 01/11/2013 23:33
    • I am 6 months removed from surgery to repair a ruptured patellar tendon. Recovery has gone very well, I'm back to full range of motion and strength is continuing to return. I do have some pain similar to patellar tendonitis/runners knee when the knee is under resistance at its extremity in flexion, would this knee brace assist in pain reduction and overall movement as I continue to recover and return to an active lifestyle? The rest of the connective tissue in my knee is healthy and I have no instability issues. Thanks.
    • Yes the Reaction knee brace is perfect for someone who is suffereing from anterior knee pain. The web design of the brace is made to disperse the forces on the kneecap into the web of the brace therefore decreasing pain.
  • Skibum at 26/10/2013 06:23
    • I am 53 year old, have been sking all my life. I haven't torn anything in either knee. Would this brace be beneficial for stability and prevention for an advanced skier in all terrains. My concern is primarily moguel terrain. I do have slight soreness after long sessions. I am concerned about twisting the knee joint since i am no longer a young pup.
    • This brace is the ideal brace for anyone who suffers from general anterior knee pain. If is light wieght and flexible which makes it a great brace for skiers. The brace does have a hinge so it will give mild protection to the inside and outsode of the knee. This is not made for protection of the major ligament of the knee, if you are looking for something like that you would need to look at one of our hinged knee braces such as the Deluxe Hinged Knee Brace: https://www.betterbraces.co.uk/donjoy-drytex-neoprene-deluxe-hinged-knee-wraparound-sleeve If you have any other question please do not hesitate to ask us
  • Aurie at 24/10/2013 03:52
    • Hi,
      I am a senior in high school and my sophomore year i dislocated my knee cap and then junior year i got ACL reconstruction surgery. I still have some pain in my knee and i'm doing gymnastics this year and i don't want to tweak anything or re-injure. Will this brace help with this?
    • Aurie
      The Reaction Knee Brace is for people who suffer from anterior knee pain and need support around the kneecap. It does not however protect the ACL. The Playmaker II with the donut pad will protect the ACL and give support to your kneecap. Take a look at it on our retail website: https://www.betterbraces.co.uk/donjoy-playmaker-ii-knee-brace-1
  • Steve at 12/10/2013 19:05
    • I've got a Grade 2 sprain of the MCL and medial patellofemoral ligament, along with grade 4 chondromalacia in the patellofemoral compartment.

      I want to prevent reinjury during the recovery period, and support activity beyond the recovery period.

      I'm looking at the Reaction and the Playmaker II - any advice?
    • Steve
      Thank you for contacting product support. The Playmaker II would be the better choice for all of the conditions that you listed. It has both medial and lateral suppport for your MCL sprain and it can come with a patellar dohnut which will help with the patelofemoral issues that you have. If you have any other questions don't hesitate to contact us.
  • Brian at 12/10/2013 04:45
    • I see that this brace is okay for football and basketball but is it okay to wear for baseball? My son currently wears the pull through lite but this one looks like it would be better. Thanks in advance.
    • Brian
      Thank you for contacting product support. The Reaction Knee Brace can be worn for any sport for anyone who suffers from anterior knee pain. Is is not a bulky brace so it should fit under your sons baseball uniform easily. The differences between the Reaction and the Tru-Pull Lite is that if your son has a problem with his knee dislocating or feeling like it "pops" out", the Tru-Pull is a good brace for him but if he just has general knee pain around his kneecap then I would go with the Reaction. I hope that helps
  • andy beck at 02/10/2013 00:43
    • I have been diagnosed with patella femoral syndrome, and I only get <a href="/cycling-and-biking">pain when I am cycling</a>. Would the reaction brace be a good brace for a cyclist?
    • Hi Andy
      Yes the Reaction Knee Brace would be a good fit for you and the diagnosis you received from your health care provider. The Reaction Knee brace reduces patellofemoral knee pain by dispersing energy across the knee. Its extremely comfortable to wear because of the mesh backing and the web design, and should not hinder you in your cycling. Make sure you measure your leg 6 inches above your kneecap to get the perfect fit. If you have any other questions do not hesitate to contact us, and thank you for contacting product support.

  • Todd at 04/09/2013 23:57
    • I am looking to start running more and training for marathon. I have trouble with the dislocation of my patella on my right knee when running. I've been told by my doctors the reason is cause the muscle or ligaments that pull my knee cap into the left are weak and don't work like they are suppose to. I need the lightest and most durable knee brace for my knee so I can start really training for the marathon. Would the reaction knee brace work for me or are there better options?
    • The Reaction is an excellent knee brace that gives more support to the Patella the more movement you have, as you bend deeper the web design gives more support to tyhe knee cap tracking correctly.

  • James at 25/07/2013 16:59
    • Hi! I I wrenched my knee quite a while back, eventually had arthroscopic surgery. When I exert a great effort like lunges, jumping jacks, side to side moves and trying to run at full speed my knee buckles. I can only run at about 70% capacity without any issue. I would like to be able to do cross fit training. I don't seem to have issues with certain leg exercises like the squat and leg presses but leg extensions for that knee causes great strain and is at about 50 % capacity of that of my good knee. What knee brace would best suit me?
    • Hello James,

      Are you interested in an Arthritis knee brace. This brace will offload the damaged meniscus and shift your weight to the healthy meniscus. Please see the link below.


      Thanks for Contacting Donjoy.

Is it possible to add the reaction to my fullfource brace? or do i have to wear one or the other?

    • We do not have an attachment that can be added to the FullFource. I recommend an ACL Brace for your ACL Injury. I also recommend speaking to your Physician about the other symptoms you are having, they could be related to your previous injury, surgery, etc.

    • My son has Sinding-Larsen-Johansson Syndrome. Would this brace provide pain relief or would you make another recommendation?
    • Hello, Peter -

      The DonJoy Reaction can provide mild pain relief and support for your son. It will help disperse the shock and stress put on the knee joint. However, we do not have a brace specifically designed for his syndrome.

      If you have further questions, please feel free to contact our product specialists at 888-405-3251.

      Thank you and have a wonderful day!

    • The Reaction knee brace would be appropriate for your son or the DonJoy Tru-Pull Lite. Both knee braces will help with patellar instability problems. The Reaction is also designed to distribute shock and force around the knee away from the painful areas. He might find a
      bit more relief while wearing the Reaction compared to the Tru-Pul Lite.

    • I am 13 years old and play all sports. Track season now and summer I play a little softball and volleyball. I have Ogsgood-schalauters in my knee and was told I had arthiritis in my knee. I hurt my knee during the 200 sprint relay about a week ago and is giving me excrutiating pain. Would this be a good brace to have for all sports? Is it easy to run in? Light weight?
    • Yes the Donjoy Reaction Knee Brace would be recommended for your condition and activity level.

    • Hi, I am 12 years old with Osgood shlatter and play lacrosse and football and was wondering if this brace would work for a contact sport?

    • I am 48 year old female and walk 30 minutes a day. I used to run, but knee pain has limited me to walking or other non-weight bearing exercise. I have been using Hypafix and Leukotape to correct a patella tracking issue. This has been very helpful, but I was looking for something more long term. Would you recommend the Lateral J or the Reaction? Thank you!
    • The Reaction Knee Brace would be recommended for your
      condition and activity level.

    • I am a male currently on a professional stunt team (like collegiate cheerleading) and a competitive cheerleading team where I do a lot of stunting (tossing and holding one female standing in my hands over my head) and tumbling. I have had my ACL reconstruction once and scoped twice (meniscus tears). I have no stability issues in either knee, but both knees (
      specifically above and below the knee cap) have pain during and after these activities, patellar tendinitis, and osteoarthritis. Patella straps help some, but I have to wear one above and below the knee cap and add tape to get more coverage in both areas...this looks like it would provide plenty of pressure all around the knee (which is pretty much what I do with all the tape). I know I will never be pain free but will this help relieve some of that pain?
    • Yes the Donjoy Reaction Knee Brace would be recommended for you with your condition and activity levels.

    • I am now wearing the OA Adjuster brace, and have been for two years. I have osteoarthritic in my right knee. Will the progressive pain relief brace help me better with the pain I am still having when I move around.
    • If you are still having pain and are already in an offloader this may not give the most relief for you. It may help some with the shock absorption, but will not offload any area.

    • My daughter dislocated her patella playing volleyball. The ortho has recommended this brace. The players usually wear their kneepads just below the patella to help them slide when hitting the floor. The webbing on the front looks like it would prevent sliding, and maybe cause more injury? Would she be able to wear a kneepad over the brace? What's the best fix for volleyball?
    • Yes, I would advice her to wear a pad over the webbing. The webbing will prevent her from
      sliding. Another good brace for dislocations is our Tru-Pull Lite.

    • My daughter has had an ACL replacement and is now suffering from pain due to what the doctors are calling runners knee, she plays soccer on her high school team and is very active
      She would need something that would allow her to run but still offer some support
      Is this the correct brace for that??

    • Yes, the reaction brace would be good for that condition. If she ends up thinking it's too much brace, you can try the Donjoy Cross Strap as well.

    A revelation! Comfortable and very supportive

    Reviewed by:
    I'm 46 and have severe osteoarthritis, zero cartilage and big alignment issues in both knees from injuries when I was 16. Until I get them both reconstructed, I've needed to use a brace on the right to limit its movement and keep the joint from locking. For the past several uses I've been using an Rx Donjoy brace which has never fit right, constantly slides, rotates, and restricts but has never felt supportive. Based on a recommendation, I tried this Reaction model and am sort of shocked at how much better it is. It is lightweight, very comfortable, allows much more movement and actually feels like it strengthens the joint. For the first time in years, I feel like I have some capabilities back, and on long walks, the left knee know feels much worse than the braced right one. Such a huge difference that I've now ordered one for the other leg. The web design gives it so much more flexibility in multiple directions than a more conventional design, and it feels like it is always giving the most benefit where it is needed at a particular time. I would recommend only wearing it with the spandex sleeve, however, as the rubber web pinches and pulls bare skin. Overall, this product is fantastic and is definitely improving my quality of life.
