  • Erick at 9/21/2016 1:48 PM
    • My 16 year old son had an ACL fracture, no surgery was required but the doctor recommended a brace to prevent hyperextending his knee because he has "loose" joints. He does play football so what brace would you recommend to prevent his knee from hyperextending?
    • The SE-4, would be a good brace to prevent hyperextension, but if he plays a defensive position in football, you may want to consider the Armor, https://www.betterbraces.com/donjoy-armor-knee-brace-with-standard-hinge, which is a stronger brace made to withstand more aggressive positions.

    • Sizing question.
      T:18.25 K:15.5 C:14.75
      I am not sure which size would work best for me.
      I would like to use it for kitesurfing and surfing.
      Looking to get the CL version for my left knee.
      Thank you for your time and expertise!
    • Based on the measurements you've provided the best size for you will be the Medium. You may want to also order a condyle pad kit that will allow you to change the pads at the knee center to get the best fit. https://www.betterbraces.com/donjoy-condyle-pad-kit

    • I have suffered an acute complete tear to my ACL and sprain of MCL. Of right knee. The SE-4 has been recommend ti me. I am trying determine size. My measurement of the of my thigh is 18 1/2, knee is 14 1/4 and calf is 13 1/4. How much adjustment is there on these measurements? Which size should I order?
    • Based on those measurements we would suggest a medium
  • Rohan Vast at 8/20/2016 1:35 AM
    • Hi,

      I recently had an ACL reconstruction surgery. I will be resuming crossfit after 2 months after consulting my physiotherapist. I would like your expert advise on the type of brace which will be well suited for me. I would be keeping the level of my training to moderate for at least first 8-9 months. Thanks in advance.
    • After clearance from your physician, to give the maximum support on your knee while doing crossfit, I would recommend getting the DONJOY FULL FORCE KNEE BRACE. It has the FOURCEPOINT HINGE it reduces the amount of time your knee is in an "at risk position", enhances the Four-Points of Leverage by increasing the posterior load applied by the brace on the tibia, and improves your natural gait by applying progressive resistance before reaching a firm end point during movement.

  • Chris at 8/3/2016 5:32 PM
    • Recently had ACL reconstruction surgery, 1 week ago.
      measuring my knee for the brace is tough due to swelling, should i measure my other knee?

      right now my measurements are T-18 K-16 C-14
      unaffected knee about the same except knee is 15.5. I bought a medium and it is too tight on sides of knee should i get a large?
    • The DonJoy SE4 is a brace used more for while you are playing sports after you have had an injury. You would want to look at the DonJoy Trom Advanced Knee Brace as this will keep your leg immobilized at the degree that you want. Also, you will want to use the measurements from the affected leg.
  • Justin at 7/9/2016 4:57 PM
    • How do you adjust the angle in which your leg can extend?
    • To adjust the angle of a SE-4 Knee Brace, extension stops would have to be requested from a local sales representative.
  • Hugo at 4/27/2016 8:36 AM
    • I am a runner, putting 40 miles a week.....would this brace slide down for long runs or after a time of usage? do to the sweat etc..
    • Yes the brace should stay up on you leg even while running. You may want to purchase a lycra undersleeve to prevent sliding due to sweat. https://www.betterbraces.com/knee-brace-undersleeve-cotton-lycra
  • Justin at 4/25/2016 6:31 PM
    • I work in manual labor all day for 10-14hrs a day. I have a stage 3 MCL and a stage 2 PCL tear, I'm trying to prolong surgery for as long as possible due to the extensive recovery time and rehab time. Will this brace give me back the mobility to where I could move freely again without the fear of my knee buckling?
    • Yes The SE-4 will provide multi-directional support to the knee but still allow your knoee free movement to do the activites that you need to do
  • Doris at 4/20/2016 6:38 AM
    • Fractured my right kneecap. Not displaced. Would this type of brace be appropriate/helpful in keeping leg straight? Is it designed to be adjusted for knee movement as determined by orthopaedic doctort?
    • No this brace is considered a Functional(activity, sports) brace. You will need something like the TROM Advanced post-op knee brace. This brace is able to lock in full knee extension(straight) and later can be unlocked and movement allowed in increments.
  • Ryder at 4/16/2016 12:30 PM
    • I measured myself and have, k:15", T:21 1/2", C: 14". Can you please tell me what size I should order?
    • I would suggest the medium size
  • Brian at 4/11/2016 12:37 PM
    • I tore my ACL, with no other damage. Should I purchase the ACL or the CI version? Was thinking the CI would give me superior knee support over the ACL version.
    • Either one would be sufficient although the CI strapping is greater for overall support
  • jeremy at 4/1/2016 9:17 AM
    • my question is sizing. im looking at the donjoy legend se-4 knee brace with the (CI). my leg measurements puts me floating in between sizes. thigh 23.4in/59.5cm, mid knee 15.7in/40cm, calf 16.1in/41cm. as you can see this puts me between brace sizes. which size of brace would you recommend? i stand 5'9" at 227 pounds.
    • I would suggest the large size for you leg
  • Mike at 3/20/2016 4:24 PM
    • I have an ACL complete tear and meniscus.....my knee is been trying to get out of place several times. Would it matter if I get the brace for ACL or CI?
    • You will want to go tith the CI strapping, as this will be the most supportive to you
  • Hugo at 3/9/2016 9:21 AM
    • I torn my ACL and part of my meniscus playing soccer 3 years ago. Since than I have been running, this past year when I tried sprinting (my max speed) it seems somewhere around my inner knee ( around the medial meniscus) feels like wants to pop out of place (not painful just not a good feeling) would this brace keep my knee from experiencing that pop out of place feeling? Again only happens when I sprint
    • The SE 4 will provide maximum stability to the knee which should help with that giving out feeling or unstable feeling
  • Liz at 3/4/2016 5:56 PM
    • I have an intermediate PCL tear and a sprained meniscus MCL. I need a brace for skiing. My insurance won't cover the brace so I have a tight budget. Would this brace work for skiing, or is there something better?
    • The SE 4 only comes with a standard calf which is too long for a skier. The Armor with the Standard hinge would be the best option for you. You can choose the short calf which will allow your ski boot to fit under the brace.
  • Erika at 3/2/2016 3:15 PM
    • Hi I had a complete tear of my ACL, partial tear in my MCL and meniscus playing ultimate frisbee. I had reconstructive surgery on my knee in May of 2015. Will this be a good brace for me to go back to playing ultimate frisbee?
    • The SE 4 Knee brace will provide great support for the knee after surgery. This brace has a standard hinge which will give medial and lateral support and mild support tot he ACL. Another option for ACL support with the Female Force Knee brace which has the fourcepoint hinge witch is a little better for ACL support. The fourcepoint hinge will help to prevent a re-tear of that ligament

    • I had reconstructive surgery on my ACL and on my Meniscus in October. I'm a senior in high school so I missed my senior season of basketball but I am shooting for track season! Doc says I should be okay for track and said it's up to me if I want a brace. Would the SE4 give me the support I need for both my meniscus and acl? I will be using it for throwing in track and for pickup games of basketball!
    • Yes the SE 4 would be a good brace to use for those activities
  • Adam at 2/11/2016 6:29 AM
    • My measurementsister are thigh 26.5 mid knee 17 and calf 17.5. Which size should I choose?

  • Kelly at 2/2/2016 7:46 PM
    • What is the length and weight of the SE4? And are there length options? I tore my left ACL and looking for a light rigid frame brace in something shorter than 16". I play basketball, volleyball and softball. I dont want to spend the money on a more expensive brace since my surgeon doesn't recommend wearing one at all
    • The SE-4 is 16" in length and 21 ounces. It does not come in a shorter length. The Female Force is 15" in leangth and 18oz and the ACL Everyday is 13" and 15 oz but not as good for sports.

  • Ezekiel at 1/24/2016 9:36 AM
    • My measurements are 21"-16.25"-16" what size should I get and does it work with snowboarding?
    • The SE-4 is a standard size brace which is 16 " in length and may get in the way of ski boots. You would want to iorder the large based on those measurments
  • Steve at 1/8/2016 4:40 AM
    • Older CTI Edge brace for ACL, MCL, PCL has worn out and physician recommended this brace. Knee measurements are thigh 19.5", center knee 16.5", calf 16". Should I order medium or large?
    • Because of that knee width you should order the large
  • Elizabeth at 1/2/2016 1:58 PM
    • Both kneecaps were removed in the mid70's--due to congenital dislocation and hyperextension has been normal since. I'd like to limit it (as well as risk of knees pitching me on ny face!) and hike more. Which brace do you recommend?
    • I would suggest any of our rigid knee braces for ACL support. These braces will provide moderate support for the knee for all instabilities. The braces have bilateral hinges for medial and lateral support, and the Four points of Leverage strapping system protects the ACL and PCL as well. These braces have combined support to give the knee a stable feel.
  • Jennifer at 12/28/2015 1:27 PM
    • I have a partial acl tear. Would this be the best for skiing and hiking? Also, measurements are: thigh 18.75", knee 14", calf 12.5" - should I go with a small or medium size? Thanks for you help!
    • The SE 4 has a standard calf length so it will not work with ski boots. The Don Joy Armor would be the better choice as you can get it with the short calf. You will want to order the medium

    • im looking for a knee brace that i can use at work im on my feet all day and thats good for runing and paintball i have some arthritis in both of my knees and just had surgery for torn cartilage behind my knee caps
    • Cody
      That brace will give you general knee support and can be worn during everyday activities, and sports
  • Tyler Nuthals at 11/10/2015 4:28 PM
    • I had osteosarcoma in my left knee. Osteosarcoma is a bone cancer, I lost my whole knee and 3/4 of my quad. I have a divot right above my knee, it goes in about an inch. I am just wondering if you've dealt with anything this bad? I don't want to give up on all exercise because I won't let this beat me. What knee brace would you recommend for me if I were to try snowboarding? I know it sounds extreme but hey we only live once right?
    • Tyler
      Any one of our rigid knee braces should provide general support for the knee joint and can help keep the knee stable during activities. If you are able to snowboard , then I assume you are functioning very well and a knee brace that have a short calf option would be better. I would suggest the Don Joy Armor
  • Reina at 11/3/2015 7:32 PM
    • I had ACL reconstructive surgery back in the end of February, and I'm about to start to ease myself back into basketball season. Will this be a good brace for me?
    • Reina
      Yes you can wear the SE 4 for playing basketball after an ACL surgery.
  • Katherine at 11/2/2015 5:20 PM
    • I have a minor ACL tear as well as some articular cartilage damage. I am also a competitive cheerleader. Would you recommend this brace for me?
    • Katherine
      This brace will help with the problems that you are having with your knee.
  • Kadee at 10/2/2015 5:57 AM
    • I had an ACL reconstruction surgery in March and I'm pretty close to being released. I'm a high schooler and play basketball year round. Would this be a good brace for me?
    • Kadee
      The SE-4 Knee brace is for ACL injuries so you should be good wearing this while playing basketball.
  • Joe at 9/17/2015 6:58 PM
    • I have an unstable patella and a partial acl tear, and i was wondering if i would be able to wear my patella sleeve under this brace. Also is the brace slimmer than the Donjoy Playmaker brace? (i am using this one currently
    • Joe
      It is possible that a sleeve would fit under the brace but you will need to make sure that your measurments are not at the end range of a size. The brace may be too tight if that is the case
  • Victoria at 9/11/2015 12:45 PM
    • I have an LCL injury and baker's cyst on my left knee. I'm a dog trainer and need to wear it for stability. I currently have the Reaction knee brace, which is good but gets hot outside. Would this be a good brace for me and which compartment should I order?
    • Victoria
      The SE-4 Knee brace will provid protection to your knees ligamentous structures with our "four points of leverage" strapping system. The CI strapping configuration will provide overall stability to the entire knee
  • Bruce at 9/10/2015 4:28 PM
    • Is this the proper knee brace to purchase for a high school football player (linebacker) that suffered a hyperextended knee injury?
    • Yes this brace will provide protection of the kne to further injury. The brace should prevent hyper-extension and provides stability to the knee
  • Elizabeth at 9/2/2015 7:32 PM
    • My new brace is a uncomfortable under the hinge on my outer knee. Does it take time to get used to wearing it?
    • Elizabeth
      The brace may take some time getting used to if you have not worn a knee brace before. But , the brace should not cause pain so if you are feeling pain at the knee joint, is it possible that the brace is too small there? Maybe a thicker condyle pad might help. You could try the air conyle pads https://www.betterbraces.com/donjoy-air-condyle-pads
  • Tim King at 8/10/2015 8:44 PM
    • Which would be best for a meniscus injury : ACL, PCL or CI
    • The ACL strapping would be advised for a meniscus tear.
  • Marquise at 6/15/2015 9:17 AM
    • I play football as an offensive lineman, and looking to get knee braces to help protect me. I only plan to use these for one season, and I am trying to not use as much money. Could I still use these or would these not last and I should go for the Armour.
    • The DonJoy SE-4 Knee Brace can be used for football, but we try to stay away from suggesting it for high contact sports because the frame is not as durable as the Armor or the FullForce. Typically for your position we would suggest going with the Armor so it can withstand the abuse from those hard hits. See the link: https://www.betterbraces.com/donjoy-armor-knee-brace-with-fourcepoint-hinge
  • Billy Timmins at 6/8/2015 7:25 PM
    • will this brace help with my knees hyperextending ?
    • Yes, the DonJoy SE-4 Knee Brace will prevent hyperextension. It comes with a 10deg extension stop installed in the hinge.
  • Richard Wiggins at 5/13/2015 5:39 AM
    • My left knee is unstable due to several meniscus injuries, detached ACL, and just plain life over the years. Under controlled conditions (working out at the gym or bicycle riding) my knee supports my exercising. However, I have been doing short mud runs and obstacle courses. My knee is deteriorating because of them but I am not ready to stop. What braces would hold together doing a Tough Mudder and support my knee?
    • Richard
      I think a rigid knee brace will give you the extra support that you want during those high intesity activities. The Don Joy SE-4 Knee Brace will provide more support for all of the ligament of the knee. Another option is the Fortitude Knee Brace https://www.betterbraces.com/donjoy-4titude-knee-brace
  • Nikki garland at 5/4/2015 4:49 PM
    • I am an active 30 something lady that had ACL reconstruction surgery in February and I am looking for a brace to be able to ride horses, four wheelers, and throw a ball with my grandson. No high impact sports just a Zumba class and maybe some insanity work outs. Will this brace be enough support and will it be easily cleaned and cool?
    • Nikki
      Yes the Don Joy Se 4 Point will give you protection for the ACL during all of the activities that you would like to do.
  • Glenn at 5/1/2015 7:01 PM
    • My measurements are as follows:
      Knee 16.5 inches
      thigh 19.5 inches
      calf 16 inches
      I seem to fall between a medium and a large...which do you recommend?
      My sport is surfing with a torn meniscus
    • Gelnn
      In order for you to get your knee into the brace you will have to go with the large size. The fram is malleable so you should be able to squeeze the thigh cuff to make it a little tighter on your thigh.
  • Daniel at 4/24/2015 3:40 PM
    • I tore my ACL and meniscus about 10 years ago and was wondering if this brace would help me out with weight lifting? I also play paintball on occasion as well.
      My thigh is 20.5 in, knee is at 16in, and calf is at 15in. What size would be best as well?
    • Daniel
      The this brace will work for you during wieght lifting your measurments have you at a medium with the thigh and calf but a large at the knee. I would try the medium, but it may bee too tight. A large will be too big on your leg and will most likley fall down.
  • Regina at 4/20/2015 7:35 AM
    • I detached my ACL while skiing and tore my medial meniscus many years ago, I did not have surgery, just therapy which worked great, however I've recently begun running for exercise and need some support for my knee (it has been known to pop out of place since I began running) - which of the configurations do you recommend? Would the ACL or the CI be the best option?
    • Regina
      I would reccommend the CI strapping.
  • Katie at 4/2/2015 11:39 AM
    • Well I was looking for another brace that was less expensive than the full force brace (which I have) I love that brace....I loved it so much that I wore it out. I'd get that brace, but it might be a little pricey for me right now. Any who... This is for my other knee. I have patella tracking disorder. Its torn up my knee and I will be having surgery in a few months. Until then, I need a brace thats going give me stability. My knee is starting to give out on me.. I've also got a loose fragment floating around in there.I have arthritis too. Is this brace good for ligaments and keeping knee parts where they need to be? I need a brace that's going to work for me now and until after I get my knee fixed.

      I like these Braces because they don't weigh me down. I hate neoprene at this point. I work in theater/ live productions and around horses. This is why I like heavy duty braces.
    • Katie
      The SE 4-Point provides the basic frame of the traditional legend at a fraction of the cost. It is ideal for moderate to severe ACL, and/or PCL, MCL and LCL instabilities. The outer coating provide a protection layer to the frame for contact.
  • Ron C at 3/13/2015 2:57 PM
    • I have a small meniscus tear and minor case osteoarthritis my Physical therapist suggested that wear a knee brace when engaged in athletic activities. Can I wear this brace for the Spartan and Tough Mudder obstacle course races and martial arts practice?
    • Ron
      The SE-4 Knee brace might be not be the best brace for the problems with your knee. I would suggest the Reaction Web Knee Brace. The brace will absorb forces on the front of the knee and dispearse them away causing a decrease in pain. The brace is much more flexible and low profile for easeir wear during the activities that you want to use it for. https://www.betterbraces.com/donjoy-reaction-knee-brace
  • Jeff at 1/26/2015 7:28 PM
    • Is this brace good for tennis or volleyball?
    • Jeff
      The SE4 can be worn for any sport
  • Billy Timmins at 1/23/2015 3:22 PM

    • Billy
      Yes you can install the Tru-Pull Attachement on this brace
  • Hunter Jones at 10/14/2014 4:24 PM
    • I just got sugary on my knee and its still unstable and loose. I got it cleaned up inside of my knee what brace option should i order?
    • Hunter
      It depends on what you are wanting to do in the brace and what you were originally diagnosed with. The donJoy SE 4 is a good brace to protec all the ligaments of the knee. It will give you the support that you need to feel stable. It can be worn while doiing everything
  • Monroe at 9/23/2014 12:03 PM
    • Hi , Just wanna ask is this the right braces for me?.. last week i have a meniscal tear and just wondering. I'm still in the process of healing. just wanna know, am i able to go back to my previous skills with this brace or what brace suits me , even though i won't have to do surgery..or surgery is a must for meniscal tear? should i need to do surgery before using this brace? thanks in advance!
    • You can wear this brace with a meniscus tear and still do activities. It should give great support. You need to ask you physician if you need to have the surgery
  • JARO at 9/23/2014 10:07 AM
    • Hi there, just wanna ask. i recently have a torn meniscus on my left knee and don't want to have surgery. I still want to play basketball without being re-injured. is this braces can help go back from previous speed on the game and also jumping, i kinda jump high you know, so i'm also kinda worry that my game will change. can i still be that much on the game even though i have torn meniscus and not to mention i also have torn acl on my right knee 6 years ago and it's healed on it's own.

      So, that's it ...looking forward for your reply ASAP, because i feel so depressed having this kind of injuries. thanks a lot! :D
    • You should be able to play basketball in the brace. It should not slow you down or affect your jump, however your meniscus tear may do that since you are choosing not to get it fixed.

    • which configuration would be best to order with needed MCL support. Should i choose the CI or the ACL configuration?
    • The ACL configuration will give excellent support for your MCL issue. The CI is used for ACL and PCL issues.
  • Deon at 8/25/2014 1:27 PM
    • I am looking for lock out plate to restrict bending to 90 dgrees and Double D clips to add additional strap to my brace for additional support. Is this spare parts available?

    • Deon
      that brace is a patient ready brace so it cannot have an extra strap added to it. The brace should have come with standard stops to you can add the flexion stop to stop bending the knee past 90 degrees. If you do not have the stops then you will need to contact a local sales rep to see if they can get the stops for you and install them for you. To find your local sales rep please follow this link:

    • I am in my fifties and both of my knees are artificial. I have been in martial arts for many years. My question is: Will this brace help protect my artificial knees when kicking.
    • Thank you for your question. This brace will add stability to your knee joints. If you feel laxity or have hyper extension concerns this brace would be a good fit for you.
  • Colton b at 6/25/2014 7:51 PM
    • Hi, I am a football player and I have had knee braces in the past. But they all fit on the outside of my pants. Will the SE-4 fit on the outside and if so will I knee to get a bigger size to make it fit on the outside?
    • Colton
      Our braces are meant to be worn against the skin, that is haow they are going to funtion correctly. The brace could be worn on the outside but it will most likley slip down your leg
  • joseph at 6/13/2014 10:06 PM
    • Hi I was wondering if the small middle piece of the knee brace protects the patella really well?
    • The middle of the brace or hinge has padding on both side of the knee but should not touch the patella at all. Your patella will be exposed as it would be with any rigid knee brace. If you are looking to protect your patella i would suggest something differrernt such as a soft hinged knee brace, the Playmaker https://www.betterbraces.com/donjoy-playmaker-knee-brace or the DonJoy Hinged H buttress https://www.betterbraces.com/donjoy-hinged-h-buttress
  • Ron at 5/25/2014 5:45 PM
    • I have a meniscus tear that was repaired. I'm in the Navy and have to run for my fit testing would this brace work well with getting the cl I also like cross fit and bike riding. Thank you
    • Thank you for your question and your service. This brace can be worn for your diagnosis and activity level. It would be suggested to call customer service to place the order on this brace. Some of the sizes/strapping types are on back order so it would be best to verify the one you need could be shipped out right away.
  • Sean at 4/28/2014 3:12 PM
    • I have a right LCL injury. Is the ACL knee compartment the best choice? I'll be using for softball and golf.
    • Yes the ACL strapping would be the correct strapping configuration
  • Angus Livingston at 2/23/2014 10:33 PM
    • I had surgery on my meniscus and instability in my mcl would the SE-4 be a good choice for me seeing that I play softball, if so what option would I chose for this brace?
    • Thank you for your question. The SE-4 Knee Brace is designed for contact sport for a person with your injuries. You may also look at the Armor if you do a lot of sliding. It is a thicker brace and can withstand more pounding that the SE-4.
  • joe at 2/17/2014 4:01 PM
    • I play lacrosse and i am in need for a more advanced brace and i was wondering which you would prefer for me to get. i have a partial acl tear and a past mcl tear. and is the se-4 any different from the fullforce ligament knee brace?
    • Thank you for your question. The FullFource and the SE-4 are both rigid frame braces that use the 4 points of leverage position the tibia and the femur to better protect your knee. Both braces can be worn during contact sports which would make them good options for you.
      The SE-4 only comes in one length, standard. It is 16" in length and comes with a 6 month warranty.
      The FullFource has a 1 year warranty on the frame and hinges. It also has a Fource Point hinge which is an added feature to protect the ACL. The fullFource come in 2 sizes, standard at 16" and short calf option which is 15".
      If you have any questions about these products please don't hesitate to call us.
  • James at 1/8/2014 1:24 PM
    • I have had an incomplete tear in my lateral meniscus and have had knee problems over the last 4 years with re-injuring back and forth.

      I play basketball often and go skiing several times each year. Would this be the brace I should get for my needs or should I look at another like the playmaker II?
    • James
      The SE4 would be fine for playing basketball but the length of the brace is 16" so it might not fit with ski boots. If you want a rigid brace that will fit the Armor would be able to do that becuase you can get it with a short calf. A shorter soft hinged knee brace will do the trick as well such as the Deluxe hinged knee brace.
  • Laura at 12/31/2013 9:04 PM
    • how much does this brace weigh?
    • Laura
      The brace weighs 21 oz
  • Amy B at 12/26/2013 8:00 PM
    • My son had acl reconstruction and? meniscus surgery as well. He is a wrestler in high school. Are these braces allowed in wrestling competitions?
    • Amy
      To be sure you should contact the coach and ask him the rules but, he may be able to wear it with a sports cover on it.
  • Katey at 12/4/2013 9:12 AM
    • I play softball and my positions are Catcher and Shortstop and I am going through physical therapy right now but which brace would be best to prevent further injuries to my knee
    • Katey
      Thank you for contacting DJO. Without knowing what your previous injuy was, the DonJoy SE-4 Knee Brace will give support to moderate to sever injuries to all of the ligament of the knee. It will protect your knee from further injuries and you should be able to play both positions on the softball field
  • Brian at 12/2/2013 5:55 PM
    • Could I reshape the brace as my thighs and calves grow bigger
    • Brian,
      This brace has some malleability to its frame. However, if you have had large amounts of mass gain you may want to get a larger brace for a more comfortable fit.
      Size Thigh Knee Center Calf
      XS 13" - 15.5" (33-39 cm) 12"-13" (30-33 cm) 10"-12" (25-30 cm)
      S 15.5" - 18 .5" (39-47 cm) 13"-14" (33-35 cm) 12"-14" (30-35 cm)
      M 18.5" - 21" (47-53 cm) 14"-15" (35-38 cm) 14"-16" (35-40 cm)
      L 21" - 23.5" (53-60 cm) 15"-17" (38-43 cm) 16"-18" (40-45 cm)
      XL 23.5" - 26.5" (60-67 cm) 17"-19" (43-48 cm) 18"-20" (45-50 cm)

      Thank you for your question.
  • kobe at 11/12/2013 11:52 AM
    • Hi, im a running back in football and i was wonder what brace would you recommend without it weighing me down
    • Kobe,
      The SE-4 is a fairly light weight brace. It is not uncommon for athletes to wear this brace. If you have an ACL injury you may want to look into the FullFource as an option. Thank you for your question.
  • Lauren Mcilmurray at 11/1/2013 6:03 AM
    • I have a MCL grade to tear would this brace work for basketball
    • Lauren,
      For a MCL injury you will want a brace with hinges so the SE-4 will give you that support on the medial aspect of your knee. This brace will also give you our four points of leverage that will isolate and anchor your femur and tibia in a position that adds security to your Ligaments. You may also want to look at the PlayMaker 2. The PlayMaker 2 with FourcePoint hinge is a great brace for noncontact sports. Thank you for your question. Please let us know if you need any more assistance.
  • Kyle Bates at 10/12/2013 6:44 PM
    • Is the Legend SE-4 recommended for skiing? I need a brace as a free-skier and active backcountry ski guide, who wears a brace sometimes continuously for 8-12 hours at a time. Any input is greatly appreciated.
    • Kyle
      Thank you for contacting product support. The Legend SE-4 is a good brace for moderate to severe ACL instabilities as well as PCL, MCL and LCL. It is made for contact sports, and has our Four-Points of Leverage strapping system which will help protect the ACL. Another suggestion although it is a little more expensive than the Legend is the Armor Ski version https://www.betterbraces.com/donjoy-armor-knee-brace-ski-version. It is designed for skiers having a shorter calf and deflector on the inner hinge. It also has our FourcePoint technology which will decrease chances of injury to the ACL. If you have any other questons do not hesitate to contact us
  • christian at 8/25/2013 3:11 PM
    • I have torn up meniscus and ligaments in my knee and need a brace to wear at work. Do any of the hinged braces fit nicely under clothing?
    • The Fullforce is a low profile brace that fits under clothing, so does the ACL Everyday.
  • Derrik at 8/20/2013 6:01 PM
    • Is this a good brace for knee injury prevention? I am a football lineman and want extra support to protect my knees from major injury. Thanks.
    • This has the same support of all of our rigid hinged knee braces, because of the material used it may not withstand the punishment of a lineman, this is why we recommend the Armor, our most rigid framed brace and used by 21 of the 25 BCS football teams for their linemen.
  • Tara at 8/6/2013 7:57 AM
    • I have had multiple surgeries on my meniscus to repair latitudinal tears. I also had ACL reconstruction several years ago. I'm told that all of my ligaments are extremely loose causing more instability - and that along with a small meniscus tear leaving it almost impossible to repair again as I'll most likely just continue to re-tear. Both of my knees hyperextend as well. I have the most instability when swimming or doing activities where my knee is bent / hanging. I need something that's more of an everyday brace for any activity. Not sure if this is the most appropriate brace or not, but the fact that I can wear it in the water is what interests me the most. Any advice would be helpful.
    • Hello Tara,

      You can wear any one of our braces in the Water, we recommend that you rinse when you exit the Ocean/Pool. I recommend the Full-Fource, its the lightest ACL brace we have. This brace features the FourcePoint Hinge which provides additional ACL support. You are also able to insert Extension Stops if needed to protect against hyperextension.

      Thanks for Contacting Donjoy.
  • Sherri at 8/1/2013 5:35 PM
    • Are the braces marked right or left? If so where are they marked?
    • Hello Sherri,

      Yes the brace is labeled. Pull the thigh liner away at the edge, you will see the size, and left or right label on the liner.

      Thanks for Contacting Donjoy.
  • Big Mel at 7/18/2013 5:36 PM
    • Does the SE have support to give some relief of some OA symptoms. Im a basketball player who has had an ACL reconstuction in 2008. And im have some OA discomfort. The Dr told me me that had some OA going on when i got my surgery.
    • Hello,

      I recommend an OA brace. Take a look at the OA Fullfource, it's an OA brace and ACL brace. This brace will take the pressure off the injured meniscus.


      Thanks for Contacting Donjoy.
  • Julie at 7/11/2013 11:17 AM
  • Mauro Lehner at 6/12/2013 7:28 AM
    • Can you add Flex/Extensión stops to the SE-4 Version of the legend? You say it has an instaled ext stop at 10 degrees?
    • Yes extension and flexion stops can be added to any of our off the shelf rigid hinged knee braces. All of our rigid hinged knee braces come with a 10 degree extension stop installed.
  • Trevor Danley at 6/2/2013 6:04 PM
    • I am an active guy playing baseball and working out a lot. I hurt my MCL playing football and am looking for support. My only thing is I'm a catcher and I don't know if this would fit under my shin guard and if it would allow me to get into a full squat. Could you let me know if this would limit me catching?
    • Hello Trevor,

      You have Full Range of Motion in all our Off the Shelf Bracing.

      Selecting a Brace depends on the level of activity you are participating in.

      For Baseball Players I would recommend the Armour, its the strongest frame on the market, stronger than our Custom Defiance Brace. It's intended for contact sports like football, soccer, where their is lots of contact and sliding. Since you are a catcher and players will be sliding into you I recommend the Armour, FullForce, or 4titude, these have a sleek design.

      The SE4 is a little thicker in the Frame, but you may be able to get this brace under your shin guards.

      find links below.

  • marissa m at 4/15/2013 5:11 PM
    • I have an unstable ACL/possible tear - I play D2women's soccer. Is this the right brace for me
    • For soccer You should look at the Armor it is our most rigid off the shelf knee brace and can handle the physicality of soccer. Or the FullForce, they will be able to handle sliding and the physical pounding the brace will take.
  • Deon Viljoen at 2/10/2013 9:42 PM
    • I have ruptured ligament on inside of knee, will SE 4 be OK? My knee is 8 weeks post surgery 44,5cm, will large be able to fit? My thigh and calf is 48,0cm? Thank you!
    • Hello, Deon -

      Yes the DonJoy Legend SE-4 will provide appropriate support for your knee ligament. Currently your knee measurement is a size XL. You stated "My thigh and calf is 48,0cm" - did you forget the thigh measurement or is your thigh and calf both 48.0? Your calf also measures an XL, however if your thigh is 48.0, then it is a medium. I would recommend an XL to you.

      Thank you and have a wonderful day!
  • John at 2/9/2013 5:09 PM
    • I play football and recently suffered a torn meniscus and my ACL is REALLY unstable. Would this knee brace help stabalize my knee and protect it from future injury? Thanks.
    • Hello, John -

      Yes, this brace will assist in supporting your ACL as well as overall knee stability during activity. However, if you are looking for a brace to use during football, we recommend the DonJoy Armor as it is has a more sturdy frame and made to withstand more sheer blows to the knee. It is designed for high impact and collision sport athletes.

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

      Thank you and have a wonderful day!
  • Dusty at 2/2/2013 10:27 AM
    • Is this the right brace to use for contact sport like jiu jitsu? I have a partial tear on my
      acl and the sport that i do is jiu jitsu
    • Hello, Dusty -

      This brace can be worn to support your ACL for activities, however in higher contact activities such as jiu jitsu we recommend the DonJoy Armor, designed for more collision, high contact sports. The Legend SE-4 can be worn during your chosen activity and will provide the appropriate amount of support you need.

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

      Thank you and have a wonderful day!
  • NH at 1/19/2013 11:25 AM
    • I'm a defensive back on a women's football team. I have instabilities on my left knee including hyper extension and mcl and acl. Would this brace be sufficient or should I move up to the armor or full force?
    • Hello,

      Because you are an athlete who plays football, we recommend that you go with the DonJoy Armor brace. This brace is a bit more durable and designed for athletes in collision sports (such as football). It will provide the appropriate stability for your needs.

      Thank you and have a wonderful day!
  • Hayley at 7/8/2012 9:25 PM
    • Is this brace best for ACL post-op surgery?
    • All of our rigid knee braces have the 4 points of leverage system design which aids in ACL stability. The durability of the brace would depend on what activities you are planning.
  • Rolando at 6/22/2012 9:04 PM
    • I was wondering can I wear this brace while I go swimming in the ocean?
    • Yes just wash it after with tap water to get the salt off of the brace and let air dry
  • katie at 6/9/2012 10:10 AM
    • how many hours a day can you wear this?
    • Hi,

      The product can be worn as long as needed.

      Have a nice day.
  • TJ at 5/8/2012 8:52 PM
    • I am looking for a brace to wear while water skiing. Will this brace hold up being in the water? Any special care instructions? Thanks.
    • Yes it has a rubberized Kraton coating to protect the aluminum frame from rust and corosion. Simply rinse with fresh water after each use and air dry.
  • susana at 5/7/2012 5:51 PM
    • Can this be worn over slacks?
    • The braces are not really designed to be worn over clothes, as it can cause the brace to slip, or the pants to get bunched up in the frame. Wear it directly on the leg if at all possible.
  • Aj at 11/6/2011 7:36 PM
    • which option would i choose if i have an LCL instability? PCL,CI or ACL
    • Hi Aj,

      Choose the ACL strapping option for a LCL injury

      Have a great day.
  • Lei at 10/9/2011 8:38 AM
    • Your options are pcl, ac, or cl for knee compartments. What does this mean?
    • PCL=Posterior Cruciate Ligament, ACL = Anterior Cruciate Ligament, CI = Combined Instability (PCL & ACL Tears), Knee Compartment = Medial or Lateral Joint Line Osteoarthritis.
  • Brandon at 11/5/2010 1:03 PM
    • Is the CI version for the MCL? What is the difference between the Legend SE-4 and the Legend?
    • The CI version will address both ACL and PCL. The Legend SE-4 is the same as the Legend, but with an extra set of pads and liners.
  • john at 7/5/2010 8:03 PM
    • Is this model also made of Aircraft aluminum?
    • Yes, but it also has a Kraton coating to protect from chips and damage.
