    • I had surgery for ACL several years ago. Now I have a slight ACL tear and small meniscus tear. I have a DonJoy brace but have lost the sleeve. It was rubber and provided support on its own. I only need the sleeve now. Is this one thick and tight enough to provide some support?
    • I believe the sleeve you are looking for is the Neoprene Knee Brace Undersleeve.
      Please see link below:

    • Are there replacement pads and straps for the Donjoy knee braces?
    • Amy
      We do sell replacement parts for some of our knee braces. https://www.betterbraces.com/parts-and-accessories If it is not available on this website it can be purchased from DJO Global direct.
  • Adam at 9/21/2015 11:45 AM
    • I see on the Don Joy under sleeve display pictures, that the top of the top of the sleeve is wrapped over the top of the knee brace. I have to wear a support knee brace for a lose of 2 cartlidges and miniscus in my knee.Would I have to buy a sleeve 1 or 2 sizes larger than my size for the sleeve to wrap over the top of my brace
    • Adam
      Usually when ordering a undersleeve you would just order the same size as your brace, but if you want the sleeve to wrap over the top of youbrace, you might want to go a size up
  • Elizabeth at 8/2/2015 12:40 PM
    • I wear a custom ACL defiance brace when I play field hockey and lacrosse. I go to school in the south and my brace tends to fall down when I sweat a lot, would this undersleeve help?
    • The DonJoy Undersleeve Cotton/Lycra for Knee Braces will help with skin irritation and chaffing, but not really control brace migration. The DonJoy Neoprene Undersleeve, is better suited for helping keep the brace up on the leg.


  • Shannon at 7/1/2015 8:11 PM
    • I have a new DonJoy ACL Everyday bought from this site. I also purchased one sleeve just in case and it turns out I have to wear the sleeve due to some irritation from the brace and sweating. I need to order a few more sleeves to allow for washing. Before I choose the same basic sleeve, I noticed a girl in my Physical Therapy clinic with a custom ordered DonJoy (ordered by her dr for her to play sports) and her sleeve is Lycra/cotton with an opening at the knee cap. How do I get hold of one of those? I would prefer one or two of those in my collection for these humid summer months - as much air as possible when in the brace 24/7 ya know? Do you sell those sleeves with patella opening??
    • Unfortunately, the Cotton/Lycra DonJoy Undersleeve is not available with an open patella, only closed. The Neoprene Knee Sleeve does have an open patella.
  • Deborah at 5/5/2015 12:21 PM
    • I have seen several requests for the sleeve to be in light colors . . . white or tan . . . it's a bit shameful that this request hasn't been met . . . what is the problem? I sweat with the black sleeve in the Summer months . . . and I'm a thin and fit person. I bought the OA brace for over $600. and can't get a sleeve for $25. in a light color. I'm a disappointed customer.
    • Deborah
      We are sorry that you are not happy with the color of the undersleeve. Unfortunately the sleeve will not come in any other color than black.
  • Josh at 3/4/2015 8:50 AM
    • I have a large Playmaker FourcePoint brace because my measurements are calf - 16, thigh - 21 1/2, and mid knee - 15 3/4. However, I have read in some of the reviews that you need to buy two sizes bigger than your measurements. I need this sleeve because the brace is chaffing my inner thigh and the back of my knee. What size should I get with my measurements?
    • Josh
      You do not need a brace that is two sizes up. Your measurements fall within the large brace so you have the correct size
  • Kim Rushton at 1/20/2015 11:36 PM
    • My daughter wears the Defiance ACL brace or soccer and lacrosse. It chafes her behind the knee. I bought a neoprene sleeve and she hates how tight it is, so I'm looking at the cotton Lycra undersleeve. I measured upper as instructed 7" above middle of patella and its 18.25. Would you recommend this sleeve for her and what size? Her knee measures 14", mid- calf 13".
      Thank you for your help!
    • Kim
      I would reccommend the lycra undersleeve and you shold purchase the same size as the neoprene under sleeve, but from the measurements that you provided you may want to order the medium size
  • Mirza at 1/7/2015 9:36 AM
    • I am polio patient
      I can not walk without holding my knee with force.
      Is there any locking brace available or not , which keep my foot straight at walking period .

    • You would need to take a look at a brace that is not available on our website. It is the Playmaker with the droplock hinge. The hinge can be locked when you stand to keep the knee straight so it will not buckle. You would need to go through DJO India to see if you can get this brace.

  • Jim at 12/11/2014 4:25 PM
    • My daughter wears a Don Joy brace on her left knee and needs something to wear on her right leg to protect her leg from contact with her brace....would this sleeve be suitable?
    • Jim
      We do have a brace cover that your daughter can wear over the brace to cover up the hinges and protect the opposite knee. https://www.betterbraces.com/donjoy-sports-brace-cover
  • Tony Paternostro at 10/11/2014 8:56 AM
    • I wear 2 Futuro Sport baces, and lately I am breaking out in hives. The doctor said I should get an under sleeve to wear. Will the lyra/cotton sleeve keep my leg dry and will the braces stay in place?
    • You can try the sleeves they are used to be worn under our rigid knee braces to preven the braces from slipping or causing any skin irritation
  • Brittney at 10/8/2014 2:43 PM
    • Is this material like yoga pant material? Also will it fade when washed in hot water?
    • Brittney
      It is a soft cotton material that stretches, it does not fade
  • Richard at 9/13/2014 9:06 PM
    • Perhaps you would consider doing the sleeve in tan or white for the summer to help with the heat. Thanks...
    • Thank you for your question. This request will be passed on.
  • John at 6/10/2014 11:00 AM
    • Do these sleeves come in any other color than black?

      I am wondering how hot to wear this during the summer?
    • Thank you for your question. The under sleeves are designed to be worn under the rigid knee braces for various reasons ranging from skin irritations to suspension concerns. It is a thin breathable material and should not trap much heat inside. If you are looking for something other than an under sleeve to be worn under a rigid brace, please feel free to call product support 888-405-3251.
  • megan at 6/5/2014 6:49 AM
    • Where on my brace would I be able to find what size it is? It appears that it is good to have the brace and sleeve size match.
    • Megan
      If you have a off the shelf brace the size should be on the inside of the thigh liner at the top of the brace. If you have a custom brace there is a sicker on the inside frame of the brace below the hinges that has a brace number. We can find what size you need by your brace number
  • Tatum at 5/24/2014 7:42 AM
    • Do knee sleeves help the knee brace from slipping?
    • Thank you for your question. The under sleeve can help with slipping in some situations. If you have questions about your brace sliding/slipping on you please call product support at 888-405-3251 to assist with your particular situation.
  • Deanna at 5/19/2014 10:08 PM
    • Hi. I feel like the small leg sleeve would be a little big on me since I'm a tiny person. Is small the smallest size you or is there an extra small size available? If not, do you offer children sizes for leg sleeves?

      Thank You
    • Thank you for your question. The DonJoy Undersleeve Cotton/Lycra for Knee Braces only comes in Small-XXL. The small fits a thigh of 15.5"-18.5", knee center of 13"-14" and calf of 12"-14". We do not have any undersleeves that are smaller than that on BetterBraces.com. If you wanted to order the DonJoy Reaction Knee Undersleeve in a XS you could order direct from DonJoy. You can call product support at 888-405-3251 for further information.
  • Chris at 5/12/2014 11:49 AM
    • Six inches above the middle of my patella (knee cap) my thigh measures 21". From the sizing chart it looks like I should order a Medium. Is that correct?

      My brace comes up 9" above the center of my patella. At that place my thigh measures 22". Does that affect the size I should buy?

      How long is the sleeve? My brace is 16" long; I would assume the sleeve needs to be longer than my brace.
    • If you have a DonJoy rigid knee brace the sleeve will come up high enough for it. Get the sleeve the same size of your brace
  • Mike at 3/23/2014 9:31 AM
    • I wear a Don Joy knee brace similar to the "DonJoy FullForce Ligament Knee Brace" when I play hockey. I have found that my knee/shin pads tend to force the brace downward when I play do to sweat and pressure from the knee/shin pad. Will this product help to stabilize the brace or is there another product that someone would be willing to direct me towards?
    • You can try the lycra undersleeve, it should help with the sweating. Another idea is the neoprne suspension strap: https://www.betterbraces.com/donjoy-neoprene-suspension-strap-kit
  • Heather at 2/15/2014 6:05 PM
    • I play all kinds of sports like basketball and soccer and I was wondering if this brace would be good to wear, I need something that will keep my knee cap in place and also be comfortable to wear
    • Thank you for your question. The DonJoy Under sleeve is designed to be worn under a rigid (hard framed brace) to prevent skin irritation and help with fitting. A few braces for your situation may be the Tru-Pull Lite, Lateral "J", or the DonJoy Performer Knee Brace. If you have any further questions about the products please don't hesitate to call us or email.
  • RALPH at 1/19/2014 5:39 PM
    • I wear a knee brace and full length compression hose. Would the undersleeve for the brace be worn over or under the compression hose?
    • Hello,

      An undersleeve for the brace is not needed. It should be worn if you have sensitive skin, or have a allergic reaction to the frame liner. Should you choose to wear it, I suggest wearing it over your compression wear.

      thanks for contacting Donjoy.
  • Jeff Jones at 11/18/2013 5:28 PM
    • I have the nano, can i fold the top & bottom of the sleeve over the brace?

    • Jeff,
      You can fold this portion over the brace if you'd like. It may stretch the fabric out. If you are looking to cover the frame we do sell brace covers. Thank you for contacting DJO.
  • Deidre East at 11/5/2013 1:36 PM
    • I recently got a Playmaker II Fourcepoint Knee Brace and there are seams that rub the back of my knee, Would this sleeve help or would it be too think in combo with the sleeve of the brace?
    • There is a thin Nylon material in the back of the knee to breathe and create additional comfort. If the side seams are causing the irritation, the brace may be too small. It is also not uncommon for there to be some initial irritation when wearing a new brace (much like wearing new shoes). You can try the undersleeve, however, it will add some bulk and deter the breathability. Thank you for your question and for contacting DJO.
  • Sean at 10/3/2013 9:50 AM
    • Do the sleeves prevent or minimize the sweat that gets on the brace lining and pads?
    • Sean,
      The sleeves will provide protection for those with sensitive skin. It will place a barrier between the brace, straps, pads ect and the skin.
      Thanks for your question.
  • Nicole at 5/31/2013 9:54 AM
    • Is the cotton/lycra material similar to wicking material in active wear where it will dry quickly? I'll be training for a half marathon during the summer months and don't want something that will hold onto sweat. I'm assuming the neoprene sleeve would be 'hotter' then the cotton/lycra sleeve. I have worn my brace over compression tights and have had no issues with brace slippage in the past. The original straps and paddings need to be replaced. I received replacement parts from the company a few years ago under warranty and they actually cause more problems than the original worn out straps/padding. I would just like to have an alternative option on hand. Thank you for your response.
    • Hello Nicole,

      Yes, the cotton/lycra is cooler than the thick neoprene. Do you have a Defiance knee brace? We have replacement parts, pads, liners, you can order for your brace. We also have Chamois Liners for the Defiance, they wick mositure away.

      Please call a Product Specialist and we may better assist you. 1-888-405-3251.
  • Tony at 4/16/2013 9:32 PM
    • If my height is 180cm what size should I choose and is it comfortable for playing <a href='http://www.betterbraces.com/basketball'>basketball</a>
    • You should purchase the same size as your knee brace is.
  • dan at 1/29/2013 4:05 PM
    • does the brace help with Osgood schlauters? please this would be very helpful
    • The DonJoy Cross Strap Knee Brace is designed to help with Osgood-Schlatters. I have attached the link to this product here: https://www.betterbraces.com/donjoy-cross-strap

  • Jim at 12/24/2012 6:25 PM
    • I have some questions on undersleeve sizing. I have a 21.5 inch thigh. Which size should I order medium or large? My Donjoy AO NANO braces are size large. Also, In the reviews, someone said to order 1-2 sizes larger than what the sizing chart indicates. And finally, in the Q&A section, there are two different lengths listed for the donjoy undersleeves. Which size, 16 inch or 18.5 inch is correct?
    • Hello, Jim -

      You would want to order a Large undersleeve. Because the Nano is only 14" in length, you would want to go with the shorter length undersleeve.

      Thank you and have a great day!
  • Sid at 9/5/2012 12:37 PM
    • Are these sleeves free of latex and neoprene?
    • The cotton/lycra undersleeve is free of neoprene and latex.

  • Rachel at 7/16/2012 2:51 PM
    • Hello,

      If I purchase "one" of these sleeve(s) at $24.99 am I getting a pair or just one of them? Would I need to purchase two (price of $49.98) to get a pair? The description isn't clear.

      Thanks so much.
    • Each sleeve is $24.99 a piece.
  • Michael M at 7/13/2012 8:44 PM
    • I wear the <a href='/donjoy-armor-knee-brace-with-standard-hinge'>DonJoy Armor knee brace</a> while playing football and a constant problem i experience is the brace sliding around on my knee which has lead to another injury. Would the Neoprene sleeve or the cotton under sleeve help prevent this more?
    • The neoprene sleeve wouuld be more beneficial, You could also try the Silicone strap pad.
  • Steve at 6/15/2012 6:35 PM
    • I was wandering if i wear the knee sleeve with brace while playing <a href='/football'>football</a> and basketball if the brace would slip up and down while playing. I am looking for something to relieve the pinching from the knee brace, but at the same time I want the knee brace snug will it will not move at all. I dont want to re-injure my knee. Thanks.
    • The neoprene sleeve would be more benificial to prevent slippage of the brace, as opposed to the lycra cotton blend undersleeve
  • Sirca at 7/21/2011 3:14 PM
    • Can you tell me the length of the sleeve? From top to bottom, my brace is 21.5' long and I have not been abe to find any sleeves long enough. The top of the brace is more than 6" above mid-patella.
    • The undersleeves are only 16" in lengeth.
  • Sugar at 7/15/2011 7:10 PM
    • How long are the knee brace undersleeves?
    • 18.5 inches.
  • Jason at 12/8/2010 6:01 PM
    • I have measured my leg 6 inches above my knee. It measured 26 inches. Which size would be the best fit, XL or XXL? XL goes to 26.5 and XXL starts at 26.5.

  • LaurieGardner at 9/16/2010 8:20 AM
    • Does the knee undersleeve come in colors like maroone or gold
    • No, I am sorry. They only come in black.
  • Vince at 7/15/2010 1:26 PM
    • Can you further explain the size chart? I am not sure what size is best for me.
    • Hello Vince,

      Here are more detailed instructions regarding measurement for the DonJoy Knee Brace Undersleeve - Supplex/Lycra

      1. Stand with your legs shoulder-width apart, legs slightly bent and leg muscles contracted.
      2. Measure up six inches from the center of your knee with a tape measure, as shown.
      3. Measure the circumference of your thigh at the 6-inch mark, as shown.
  • Mike at 7/6/2010 2:55 PM
    • Will the knee brace undersleeve help with sweating and such from wearing the <a href='/knee-braces'>knee brace</a> outside on hot days?
    • It will help in that it will help absorb the moisture. It won't keep the knee cooler, but it should make wearing the knee brace more comfortable.
  • Eric Denis at 6/19/2010 11:26 AM
    • Does the cover give any extra protection or stability to the knee?
    • This knee brace undersleeve is designed to protect the skin by adding a layer of comfortable material between your skin and the knee brace. It does not necessarily add any support or stability to the knee.
  • Michael Hewett at 6/4/2010 4:34 PM
    • does the knee brace undersleeve have a seam
    • There is a thin seam that runs the length of the sleeve on the back of the leg and very comfortable against the skin and under a knee brace.
  • BILLIE SMITH at 4/12/2010 3:14 PM
    • It is summer and I am wearing shorts. Would love to get bracesox in tan or kakhi color. Is that possible ??? Thanks
    • The DonJoy Knee Brace Undersleeve only comes in Black.
  • Tom Reid at 4/4/2010 12:21 PM
    • Can the undersleve be worn with the OAdjuster Knee Brace?

      Also what is the difference between the Replacement Kit-Lateral and the Replacement Kit- Medial for the OAdjuster? They appear to be identical.
    • The DonJoy Knee Brace Undersleeve - Supplex/Lycra can be worn under the DonJoy OAdjuster Osteoarthritis Knee Brace. Just be sure to match the sizing of the brace with the sizing of the sleeve (Large brace - Large sleeve, etc)
