    • 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 28/04/2014 23:12
    • 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 24/02/2014 06:33
    • 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 18/02/2014 00:01
    • 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 08/01/2014 21:24
    • 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 01/01/2014 05:04
    • how much does this brace weigh?
    • Laura
      The brace weighs 21 oz
  • Amy B at 27/12/2013 04:00
    • 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 04/12/2013 17:12
    • 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 03/12/2013 01:55
    • 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.

  • kobe at 12/11/2013 19:52
    • 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 01/11/2013 13:03
    • 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 13/10/2013 02:44
    • 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.co.uk/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 25/08/2013 23:11
    • 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 21/08/2013 02:01
    • 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 06/08/2013 15:57
    • 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 02/08/2013 01:35
    • 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 19/07/2013 01:36
    • 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 11/07/2013 19:17
  • Mauro Lehner at 12/06/2013 15:28
    • 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 03/06/2013 02:04
    • 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 16/04/2013 01:11
    • 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 11/02/2013 05:42
    • 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 10/02/2013 01:09
    • 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 02/02/2013 18:27
    • 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 19/01/2013 19:25
    • 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 09/07/2012 05:25
    • 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 23/06/2012 05:04
    • 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 09/06/2012 18:10
    • 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 09/05/2012 04:52
    • 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 08/05/2012 01:51
    • 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 07/11/2011 03:36
    • 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 09/10/2011 16:38
    • 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 05/11/2010 20:03
    • 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 06/07/2010 04:03
    • Is this model also made of Aircraft aluminum?
    • Yes, but it also has a Kraton coating to protect from chips and damage.
