    • Can the DonJoy Drytrx Hinged Air Knee Brace be used for basketball.
    • Yes it can, but it depends on the injury. Please consult a brace expert for a recommendation by calling 1-800-553-6019.
  • Stormie at 8/31/2016 3:11 PM
    • Do the hinges lock into place at the different angles?
    • Thank you for contacting Better Braces. The Hinged Air Knee Brace does not lock at different angles, however it has a standard hinge that is capable of putting stops into to restrict the range of motion. If you are needing to restrict motion we can help put you in touch with a local representative.
  • C at 8/22/2016 9:28 AM
    • Is this brace considers to be ridged? Thank you!

    • My doctor fitted me with the DRYTEX HINGED AIR KNEE BRACE and it itches/scratches terribly. What can I do? is there something I can put under it? There are a lot of scratchy edges and seams. I do like the support of the brace but it is driving me crazy...help!
    • Yes, we have the DonJoy Cotton Lycra Undersleeve that would work to wear underneath your brace to help prevent skin irritation. Please see the link below:

    • Hi. I have patella tendinitis and patella femoral as well as very mobile knee caps and some instability to the LCL and PCL. I wrestle at a high level and am looking for new braces as I don't like mine. Would this be a good option?
    • Matt
      The Hinged Air Knee brace will provide both patellar stability and medial/lateral control. For your injuries you could use this brace
  • Jesse at 11/2/2015 6:22 PM
    • I have recently sprained my MCL in a football game as a lineman would this be an appropriate brace to help prevent any further sprains on my MCL (lateral hit caused my sprain)

    • Can this brace be worn over a pair of jeans? I was told I need to wear it for 2 weeks straight after my injury I have and I need to be able to fit it over a pair of jeans since it will not fit under my jeans.
    • No this brace will not fit over pants, it needs to go against the skin for it to be effective
  • Mr Bajos at 4/24/2015 3:29 AM
    • what knee brace is the best for inner tear meniscus + patella fracture ?
    • Mr Bajos

  • Phyllis at 3/20/2015 10:22 PM
    • I had meniscus surgery and I am still experiencing pain. I am looking for a lateral unloading knee brace. I play (or, shall I say, want to play again) roller derby, so, I need a high impact brace that can be worn under knee pads. Suggestions?
    • Phyllis
      I would suggest the don Joy defiance custom knee brace. The Defiance has the strongest frame, made of reinforced cabon composite. The brace can be made with an OA hinge to unload laterally. One of the options is our impact guard wich can be attached to the brace and used as you knee pad on that side. This brace is used in contact sports. https://www.betterbraces.com/donjoy-defiance-iii-custom-knee-brace
  • Robert at 12/31/2014 5:54 AM
    • I have bi lateral osteo arthritis in both knees, as well as patellar malalignment in both knees. I was perscribed and given a Don Joy brace by the Dept. of Veterans Affairs, but it is a pull on type and I was hoping you all may have something that can be worn over pants that will give me the same benefits minus the irriatation issues I have with the pull on type. I pretty much need to them wear daily, as the injuries are bad enough that surgery to realign the patellar would provide no overall relief until a full knee replacement is more warranted.
    • Robert
      We do not have any wrap on knee braces that are patella stabilizers. The Drytex Hinged Air is a pull on sleeve as well. You could try the Tru-Pull Lite. It is a smaller brace with hinges in both sides and a patellar stabilizer that wraps from the outside. It might be more comfortable than the brace you are currently in. https://www.betterbraces.com/donjoy-tru-pull-lite
  • John L. at 11/5/2014 11:48 AM
    • In 1998, I had a ACL replacement. Surgeon said at the time that I also has some Meniscus damage and might have problems later in life. Most of the time the knee is fine, but occasionally (maybe once a year) it "goes out" (popping, cracking, not good hinge movement, problems on stairs, etc). I have had a reliable Donjoy brace all this time that I wear when this happens that completely stabilizes the knee and in a matter of some days it gets fine again and I can stop wearing the brace. Unfortunately, the brace no longer fits well and is a little beat up. Given this fact pattern, what replacement brace do you suggest?
    • John
      The Playmaker Ii would be a brace that could give you the support you need. It is a soft hinged knee brace that can be worn to protect all of the ligaments of the knee. https://www.betterbraces.com/donjoy-playmaker-ii-knee-brace-2
  • marcreno at 10/19/2014 11:25 PM
    • I tore my meniscus on my right knee,I don't want to get surgery because is a very small tare n the surgeon don't recommend. I am also over weight and I know I'm putting alot of pressure on it due to my weight. Is very painful when I try exercising and I want to do high cardio work outs but also by just walking it hurts. What you recommend
    • The Don Joy Deluxed Hinged Knee Brace will give you general knee support and will allow you to exercise. https://www.betterbraces.com/donjoy-drytex-neoprene-deluxe-hinged-knee-wraparound-sleeve
  • Paul Fitzpatrick at 10/18/2014 5:01 PM
    • I had a high tibial osteotomy on my right leg to re-align my knee. I had a custom rigid brace but lost it. I have used a soft brace that you buy in a sporting goods store for about 50.00 and it works pretty well but would like something better. What do you suggest?
    • Paul
      Take a look at the Don Joy Playmaker II knee brace. This brace would be a step up from what you are currently using. The brace has four straps and bilateral hinges to give you better support than other soft hinged knee braces. https://www.betterbraces.com/donjoy-playmaker-ii-knee-brace-2
  • Diane Roberts at 9/30/2014 1:12 PM
    • I have had many reactions to the neoprene in other knee braces but need a brace as I have Chondromalacia patellae, patellofemoral pain, and have sprained my mcl, and lcl. would this knee brace work for me? or what else would you suggest. the last time I wore a knee brace I had a rash that I had to take steriods to get rid of.
      thank you
    • Diane
      This brace will work for you. It has hinges for the MCL and LCL, a patellar buttress for the knee cap problems and it is not neoprene
  • Sunny at 9/16/2014 11:42 PM
    • Hello,

      I recently underwent arthroscopy on my right knee for a medial meniscus tear. It was a one inch tear and they had to shave it off and rebalance the knee. I'm planning to resume lifting and would like to know which brace would provide the optimum amount of stablity to my knee and prevent any aggravation of the injury.
    • The most protection you could give the Medial Meniscus would be to get an OA brace that would unload pressure on the meniscus. With that said, The PlaymakerII or the DonJoy Deluxe Hinged Kne will give strong to medium support, respectively.
  • Sam at 9/12/2014 3:33 PM
    • How is the air hinged knee brace inflated? How do you know what is the appropriate amount of inflation? Will the extension stops help to avoid hyperextension?
    • Thank you for your question. The air bladder is inflated and released manually. It should be snug and comfortable. The extension stops do help with hyperextension. Most of the hinged braces come standard with 10 stops in the brace. Please let us know if you have any additional questions.
  • bob reibstein at 8/7/2014 7:11 AM

  • Robin at 4/16/2014 1:53 PM
    • I bought a DonJoy Drytex Hinged Air Knee Brace about a year ago and it worked fine at first but now I cannot get the air adjustment to inflate on either side. The •Inflatable pneumatic buttresses seem to be intact bilaterally but despite pushing on them they do not inflate anymore. Any suggestions?
    • Robin
      Unfortunatly that brace does not have replaceable parts and it is no longer in warranty so the brace would have to be replaced
  • Erik at 3/14/2014 10:51 AM
    • I am looking at getting the playmaker brace. I have a multiple ligament tear in my knee and will be having ACL reconstruction surgery in the fall. I am putting off surgery because as professional guide I need to be able to lead hikes and other activities for the summer. I was thinking the drytex material would be the best choice for breath ability. Is there any reason you would recommend the neoprene one any thing else?
    • Erik
      If you are looking at the Playmaker and are concerned about the material, look at the Playmaker II. You can get this brace in the spacer material which is even cooler than the Drytex. It will be more comfotable than both neoprene and drytex.
  • Paul Petersen at 2/18/2014 11:19 AM
    • I am looking for a brace for my knee which has a torn meniscus and arthritic damage. I am a big guy at about 6'1" and 320lbs. I do not do sports anymore but I am on my feet working all day. In the past I have had trouble with the brace slipping down and pinching in the back. Can you recommend a brace for me?
    • Thank you for your question. You may want to look at the DonJoy Deluxe Hinged Knee Brace. This brace will have the option for an "open popliteal" which is a cut out behind the knee to prevent bunching and pinching. We also have a line of Osteoarthritis braces (OA braces) if your arthritis is specific to one side of the knee or the other. Please call us if you have any questions.
  • Allie at 1/21/2014 9:03 AM
    • About 2 months ago, I tore my MCL in a field hockey game. This past weekend, I tripped and had pain in the ACL region and my patella was out of place. Since then, it stopped hurting, but feels odd and unstable. Would this brace be suitable for field hockey and lacrosse? Also, is it a sleeve or wraparound brace?
    • Thank you for your question. This brace will support the MCL having the hinges/uprights on the sides. The Patella will gain some stability with the compression and patella cut out. You will have a mild amount of ligament support with this brace. The DonJoy Drytex Hinged Air Knee Brace comes in either a wrap around or a sleeve option. You can also look at the DonJoy Deluxe Hinged Knee Brace and the Playmaker with a donut for additional support.
  • Donnie Peters at 1/10/2014 12:53 PM
    • I have issues in the passed with medial plica syndrome. Actually had to have surgery on my right knee to get it removed. I was a downhill longboarder so I was always sliding but in one knee it was affected more than the other do from repetitive bending extension. Although I had familiar pains in my left side it wasn't near as sever or enough to put me out of boarding. After snowboarding recently I had a quick twist in my knee which has brought the same pain onto me. It causes it to be in a dull achy pain all day everyday and causing my knee to not track properly. Would this brace help reduce pain, give stability, track properly, and allow me to proceed in snowboarding with out surgery? I do all kinds of excerises to strengthen it back up but if my knee is not aligning properly then it's for nothing right?
    • Thank you for your question. The DonJoy Deluxe Hinged Air Knee Brace would be an appropriate brace for you. It will offer stability with the hinges and help with tracking and patella malalignment. You could also look at the DonJoy Performer Hinged Patella Knee Brace, which will have hinges and a buttress for patellar tracking as well.
  • Nick at 1/6/2014 6:12 PM
  • Garret at 12/13/2013 11:25 AM
    • I tore my MCL around 7 months ago but did not require surgery. I have since gotten back into running around 3 or 4 months ago and increased my weekly distance goal from 5mi/week to 10+. However, while the MCL still feels "odd" once in awhile it is not the major source of pain and now it seems that I have developed runners knee. Considering that winter is upon us and I also snow ski and snowkite I figured I had better get a brace. Is this the right brace?
    • Garret
      Thank you for contacting DJO. The DonJoy Drytex Hinged air Knee Brace will work for you because it will give you the medial support from the hinges and the patellar dohut will help with the anterior knee pain. If you have any other questioins please let us know
  • Rob at 10/22/2013 10:18 PM
    • I tore my meniscus refereeing ice hockey and had surgery 5 months ago. There is still considerable pain when skating and the day after. I also severely strained the MCL on this knee a few years back but thought that it completely healed.

      Which brace do you recommend?
    • Rob
      If you are having patellofemoral pain, or pain in the front of your knee this brace will work fine for both that and the MCl.

    • My 14 year old has partially dislocated her kneecap 3 times in the past year. She is a field hockey player and runner. We would rather not have surgery just yet - I think if she had worn a better brace this may not have happened (the third time happened when she was just taped.)

      We are in the process of getting second and third surgical opinions, but I would like to have some alternative options to discuss. It's been 4 weeks and she is feeling better, I would like to try letting her play with a better brace and some ongoing PT. What brace would you recommend at this point?
    • The Reaction knee brace is a great brace. It will give her support in all directions for her kneecap to keep it in the femoral groove and as she bends and puts more pressure on the knee cap, the webbing gets stronger to keep her kneecap in the correct location.
  • Tim at 8/11/2013 11:49 AM
    • Is this brace able to be worn for water sports?
    • Hello,

      Yes, these braces can be worn in the water. We recommend you rinse the brace when you exit the ocean or Pool.

      Thanks for Contacting Donjoy.
  • Steve S at 6/23/2013 4:57 PM
    • I came down straight after jumping in basketball several years ago and had no tears but since then my knee is loose if I cut or rapidly turn while my foot is planted in tennis or basketball. Primarily its lateral instability, kind of slightly dislocates laterally, not a lot . Can also happen if I hyper flex and put my foot way behind me when I am seated only occasionally . Just a tweak which hurts laterally and gets better within a day or so. No real swelling, just tightness.

      I prefer a soft brace for tennis . What do you suggest?
    • Hello Steve,

      I recommend the following Knee Braces for Tennis. The difference between each brace is material, and length of brace. All these braces have hinges which will provide support on the medial and lateral side of your knee. This should help with cutting and lateral tennis movements.

    • I was wondering what brace would be good to wear for running and biking. I tore my acl and meniscus about 10 years ago . I kept tearing my meniscus few more times so they removed it . When I run there is a slit pain . Just wondering what brace would be good for my activities. Thanks
    • Hello Amanda,

      I recommend an OA Brace, it's specifically designed to offload the pressure on the injured meniscus and shift the weight to the healthy side. Please see the link below.

    • I tore my miniscus playing a pick up game of basketball and dislocated my knee. I'm looking for a brace that will keep my kneecap in place, looking to start playing again.
    • Harry,
      The Hinged Tru-Pull Advanced or Hinged Lateral J are good braces for patellar dislocations. The hinge will give stabiklity and some protection for the meniscus injury.

    • I have torn miniscus in left knee ( right replaced ) and bone on bone issues and need support for the next three months until I return home for possible surgery. I play golf 5x weekly so I need an apparatus to take the shock and twisting which I do not overload as when younger. What would be some possiblities to reduce pain, other than stopping golfing. The left leg is 2" outbound from knee down.
    • Based on your injury and activity level the OA FullForce would be recommended.
  • Heather Stone at 12/4/2011 11:35 AM

  • Marsha harlow at 5/12/2011 3:15 PM
    • My daughter needs xl knee brace. We have several with velco straps. These braces do not stay up despite us making them as tight as possible. Any suggestions. Her patella needs stabilizing. Thank you
    • With the Hinged Air DonJoy, It is going to have the uprights and hinges in this brace, which will help keep the brace suspended along with the velcro straps. This brace will be more efficient, while still providing patella stabilization.
  • Brandon at 4/4/2011 1:34 PM
    • Can the DonJoy Drytex Hinged Air Knee Brace be used for basketball and weight lifting if you have a meniscus tear? If not what brace should be used?
    • Thank you for taking the time to email us here at www.betterbraces.com regarding our DonJoy Drytex Hinged Knee Air Knee Brace. The Donjoy Hinged Knee brace can be used for meniscus damage the Air Donjoy Knee Brace is used for patellofemoral issues. Please contact us again with any additional questions at 800-553-6019.
  • Tony Randall at 2/26/2011 4:30 PM
    • I had an meniscus removed 25 years ago. To this day my knee swells with use such as hiking or BC/XC skiing . I am looking at the braces for this specific injury. I find that my thigh is a medium 19 " and my calf is a large 16".Is it better to go with the large or medium?Need the support but am concerned about cutting off the circulation if the calf is too tight.
    • I would recommend getting the Hinged Donjoy knee brace, wrap-around, in drytex, in medium. A large would be too loose on your thigh. The wrap-around would allow for adjustability, and they drytex will stretch over time. That is your best fit.
  • dancinonwater at 2/1/2011 1:56 PM
    • how does this brace compare to the breg pto?
    • The DonJoy Drytex Hinged Air Knee Brace is a patellofemoral brace that will stabilize you kneecap; however, the DonJoy brace most compatible to the PTO is the Tru-Pull Advanced System which had the bifurcated strap to adjust the amount of support to the needs of your knee. The Tru-Pull Advanced knee brace comes with or without hinges. Another patellofemoral brace that is unique to the market is the DonJoy Reaction brace which has the elastomeric web design. The elastomeric design creates energy dispersion across the knee for optimal shock absorption
