    • should measurements be taken while in a relaxed seated position on a table or with knee flexed slightly? measurements are different and fluctuates between ordering a large or XL brace
    • For measurements, stand with your legs shoulder-width apart, legs slightly bent and leg muscles contracted. Measure up six inches from the center of your knee with a tape measure. Measure the circumference of your thigh at the 6-inch mark. Then measure down six inches from the center of your knee with a tape measure. Then measure the circumference of your calf at the 6-inch mark.

    • Let me know whether I can wear the Bionic Knee Brace under the pants?
      Thanks. Peter
    • The DonJoy Performance Bionic Knee Brace is a low profile brace but it does have protective hinges. You can wear the brace under pants as long as the pants have enough leg room to accommodate the brace.
  • Frank at 7/13/2016 5:30 PM
    • I'm a polio patient (1952) have a hyper extended knee due to loss of muscle mass back of lower leg. I need a stop to allow me to put weight on my leg and not have it lock in a hyper extended condition. Brace migration is an issue with loss of muscle condition. I feel I need a moderate to high support brace. Any help on recommending a brace.
    • The DonJoy Performance Bionic Knee Brace has a hard stop built into it to prevent hyperextension, and support knee instability with lateral and medial protection.
  • Rahim at 7/5/2016 12:50 AM
    • I have a level 2 MCL sprain/tear in my right knee from playing bball. It has been 4-5 weeks since my injury. I feel the most pain when pivoting, crossing over from right to left and when doing defensive slides (move laterally) to the left. I want a brace that will give me support but not allow me lose mobility. My physical therapist said I would lose a lot of mobility if i get a wrap around brace that covers my thigh and knee. Is this the right brace for me?
    • The DONJOY PERFORMANCE BIONIC KNEE BRACE is great choice since it is made for MCL/LCL injury you currently have. The bilateral hinges underneath the material will help you stabilize the joint against lateral forces while playing basketball. It is also lightweight which will not slow you down plus it has a breathable neoprene which will help you with the heat and sweating.
  • vince at 7/2/2016 12:53 PM
    • I've used medium and large knee sleeves for years, and the medium was a better fit. I'm a big guy 6'7" 235 lbs. My knee size is 15" but my calf is 15" and my thigh is 20.5". I've had a meniscectomy from past minor injuries and ongoing wear and tear. I would use this brace for running/jogging and light plyometric and weight training. Is a medium too small or does the sizing run small and a large would be more suitable?
    • The DojJoy Performance Bionic Knee Brace would be a great brace for your meniscus issue. Its lightweight and low profile enough for running and exercising. Your measurements do fall into the medium range.
  • Sharon at 7/2/2016 6:57 AM
    • What is the best way to clean this brace?
    • To clean the brace you can hand wash in cool water with a mild detergent then let it air dry.
  • Lynn at 6/24/2016 10:15 AM
    • I have had bilateral ACL/Meniscus repairs done. One in 1999 and one in early 2015. I already have 2 Playmaker and am looking for something smaller, lighter and more comfortable for daily use. I'm also an avid cyclist and was wondering if there is enough flexion in this brace to make cycling comfortable and give me enough movement to make cycling possible.
    • The DonJoyPerformance Bionic Knee Brace will provide both medial and lateral support, and is lighter than the Playmaker, and should still offer the flexion needed for cycling.
  • Daniel at 6/24/2016 12:04 AM
    • I am 21. I have injured my knee 4 times. The first time was during football sophomore year of high school. I partially tore my ACL going for a tackle. I did not need surgery. I did rehab for about 6 months. They gave me the brace similar to the Full Force Knee brace. About 9 months later, I hurt myself in Tae Kwon Do doing a jump kick and landed wrong. I went back to the doctor and he said I injured my MCL and LCL. I received rehab for a few months. About 1 year later, I injured my knee playing basketball. I landed wrong once again. I never went to the doctor. I did not received any rehab. I didn't really strengthen it or anything. I'm pretty sure it was just a sprain to my second incident. Then in October I injured my knee playing basketball. I landed wrong going up for a strong layup. I went to the doctor. He said it was just a sprain. He did not give me too much info. It was pretty similar to the second and third incidences, I believe. He gave me one of those cheap ACE sleeves that you can buy at CVS. I have a McDavid knee brace that has the straps but it doesn't have the metal hinges. It is one of those $40 knee braces. Every since my last injury, my knee has been getting stiff occasionally. It sometimes has like a popping cracking feeling when I walk. I feel awkward. I believe it is osteoarthritis according to the symptoms. I really want to get back to playing basketball recreationally at the gym and park. What knee brace should I get? Should I get the webbed one, this Bionic knee brace, or a sleeve like the trizone support or sleeve, or something more heavy duty? My old ACL knee brace doesn't fit anymore. Plus, it felt very bulky when playing basketball or any other sports. I didn't like it because I felt it slowed me down. I want a brace or sleeve that is supportive of my ligaments without it being bulky and slowing me down. Thanks.
    • The brace I'd recommend for your combined injuries would be the Donjoy Playmaker II. It is designed to protect the ACL, MCL, LCL and Meniscus. It isn't as restrictive as a rigid brace like the one you currently own, but it is much more supportive that a knee sleeve would be. https://www.betterbraces.com/donjoy-playmaker-ii-knee-brace
  • Chanel at 6/6/2016 11:06 AM
    • Can your knee bend all the way when wearing this brace without pain?
    • The Bionic Knee brace has an aluminum hinge that allows for full range of motion, you will not have any problems with going into a deep squat.
  • Kristen at 5/8/2016 11:11 AM
    • I have a possible ligament tear (no confirmation MRI yet, so I'm unsure of which ligament) resulting from a weightlifting injury. I jumped too wide in a clean and jerk. My lower leg bowed in lateral to medial. I'm looking for a brace that would be of max support so that I can continue lifting. Is this the right brace?
    • The Bionic Knee Brace will offer general knee support as it has biltaeral hinges. The brace can be worn during activities and should not limit you acitity.
  • Katy at 5/6/2016 9:19 AM
    • I have a torn PCL and am trying to decide between this brace and the DonJoy Economy Hinged Knee brace. My physical activity only consists of short runs/walks and pilates. Do you recommend one over the other?
    • Both the Economy Hinged knee brace and the Bionic Knee Brace are very similar. The Economy comes in Drytex material which a little cooler than the Neoprene. Both brace will offer the same level of support
  • Joey at 5/4/2016 4:21 PM
    • I am a 5' 11" high school football player and last season I underwent a tear in my LCL and messed up the cartilage in my knee as well since then I have done 6 months of therapy and have restrengthend my knee and it finally feels stable again but I am getting back into football and I wa wondering if this knee brace is a good fit for playing with during practice and the games
    • The don Joy Bionic Knee would give you both lateral and medial support and can be used for sports. This brace would be a good choice.
  • Cindy at 4/25/2016 6:04 PM
    • Which brace would work best for supporting my bruised; injured knee (side front of knee has a lump the size of a quarter) and bruised front slightly below knee cap). The activity would be forward and lateral moves. Also, I am at the higher end of Size small. Would Medium be more comfortable without sliding. I want to make sure the brace gives comfortable yet firm support. Thank you!
    • You will want something with compression for the swelling around the bruise. The Trizone knee offers zoned compresson and mild support of the knee. The brace runs a little small so if you are at the end of a small you might want to go medium

  • Joe at 4/22/2016 9:23 AM
    • Do you think the Bionic Brace will slide around, if I have compression tights on?
    • It is a possiblity that it will slide with something like that underneath it
  • nikki at 4/18/2016 5:10 PM
    • Is this a pull on sleeve style?
    • This is a wrap around brace
  • Kris at 4/8/2016 8:04 AM
    • Does this brace come in an XS? My son measures for an XS and it is not an option to order. If it doesn't is there another brace you would recommend that comes in an XS? He is 9years old and we are looking for a brace to prevent hyperextension during sports.
    • this brace does not come in a XS but we do have a similar brace on our sister website called BetterBraces.com that will come in that size. The brace is called the Economy hinged knee brace. http://www.betterbraces.com/donjoy-economy-hinged-knee
  • Missy at 4/5/2016 10:14 AM
    • I am looking for the right brace for my knee. I have pain in the middle of the front of my kneecap. When I hyperextend my knee it pops. Sometimes the pop is painful and sometimes it isn't. I do not feel pain while running or strength training, usually after. Will have pain while trying to balance on one leg. What leg brace/sleeve do you recommend for my symptoms that will be comfortable to train in? As a side note, I also have sciatic nerve issues on the same side as knee pain. My thigh measures 15.5 from mid kneecap. Please advise on size as well as I am on the low end in some braces/sleeves in a small and the high side in an xs.
    • Sounds like the Reaction web knee brace would help your knee. The brace will absorb force on your knee and decrease pain in the front of your knee. The XS/S would fit your leg

    • recently tore my meniscus, have an ultra marathon coming up. Doctor said I could run so as long as I could tolerate the pain. Scheduled a scope for later on in the year once school is out. Is the Donjon performance bionic knee brace the best brace to go with? -- I have no prior/other knee/leg issues.
    • Yes the Bionic knee brace will provide general knee joint stability for you
  • Eddie Balewitz at 3/22/2016 4:49 PM
    • I recently had reconstructive meniscus surgery to the outer portion. Two years ago I tore my acl, mcl, pcl and meniscus. I am looking for a brace that will help with running, baseball and basketball. I cannot do another reconstructive surgery!! What brace do you suggest? I am 6'2 and 242 lbs and a very athletic 44 year old man who coaches all three of those sports. Please help!!!!
      Thank You,
      Eddie
    • With all of those injuries to the knee, you need a brace that will provide maximum stability and ptoection. The Don Joy Armor with the Standard hinge will provide this for you and protect the knee from re-injury.

    • Question about sizing. I have a athletic build. Knee measure 13 inches, calf is 15in and thigh is 18.5 In looking at the size chart a small won't fit my calf and thigh but a medium will but won't fit my knee cap..suggestion??
    • The medium is the only size that will work for you. this is a wrap around brace so you may be able to make it a little tighter
  • Taran at 3/18/2016 1:07 PM
    • I have a torn ACL (not been operated on and it's been 2 years since injuring). Plus I feel a weakening in the opposite knee too.

      It is unstable and I move with a lot of caution - but I've been able to keep up a level of aerobic fitness without a collapse. I just need confidence on my knees to get into a boxing ring and move around.

      Can you recommend the best solution at each price point please?

      Thanks,
      Taran
    • The Playmaker II with Fourcepoint hinge will provide you with moderate ACL support and the hinge is designed to train the leg to stay out of the "at risk" position. Sonce your Recopnstruction was a couple of years ago this brace will provide the confidence you need.

  • Jurnee Smith at 3/16/2016 12:50 PM
    • I have had 2 ACL reconstructions in my left knee along with one bucket tear in my meniscus (totalling in three surgeries). I now have constant pain on the inside of my knee with spuratic bruising and swelling. I have been unable to exercise, other than walk, and am in constant pain. I am looking for a brace to wear on a daily basis to keep my pain level low enough to exercise again comfortably. What brace would you recommend?
    • The Bionic Knee will provide both medial and lateral support to the knee. This will give general support to your knee.
  • Samantha Arnold at 3/10/2016 8:00 AM
    • I had reconstructive ACL surgery using a patella tendon graft from my own knee in 2010 and in the same knee a bucket handle meniscus tear which required surgery in 2013. Was seen a few weeks for pain and swelling my surgeon said my knee cap is deteriorating and there isn't anything else he can do. I have very little meniscus left and knee replacement is still way down the road. I run long distances (3 miles up to 13.1 miles) Which brace would you recommend?
    • The OA Raction web knee brace can be used for both of those issues. The webing design of the brace will help to eliminated force on the front of the knee and decrease pain. The hinge can unload the area where you had the meniscus tear. The hinge goes on the opposite side of where the meniscus was to unload that area

  • Bob at 3/3/2016 11:11 AM
    • I have very little cartilage left in either knee. Its basically bone on bone. Iam a kindergarten special education teacher and golfer. What brace would help me?
    • The OA Reaction may give you some pain relief if your OA is on one side of your knee. The OA Reaction can unload the painful compartment to try to decrease some of that pain. The webing design will also decrease pain in the front of your kne as well.

    • I would suggest the Tru-Pull Lite knee brace. The Tru-Pull lite will provide some support around the kneecap but still allow for full motion. The buttress will push the kneecap into the correct position. The brace is low profile and easy to wear

He is too get a brace to help and just want to know if this brace would help or which one u would recommend. He plays basketball baseball and football.
    • Yes the Bionic Knee brace should help his knee by providing general support to the leg.
  • Mark at 2/9/2016 2:24 PM
    • Do you put on the brace standing up, and how tight should all the straps be?
    • You can put on the brace in any position comfortable but sitting my be easiest. When tightening the straps just make sure they are comfortable
  • Travis27 at 2/4/2016 6:42 AM
    • I have had a torn meniscus in my right knee for over 2 years now, only option was to have surgery (scope) and just cut away the torn parts. I haven't been able to afford to do that and my knee hurts once in a while, but mostly I feel its unstable. What sleeve would you recommend for running? I do lots of strength training but running always aggravates it after a while but I signed up for a 5k and need to train
    • I would suggest the Reaction Web knee brace. The brace will absorb the forces on your knee when you run and dispearse them away from the front of the knee decreasing pain in that area
  • Mark at 2/1/2016 6:31 AM
    • standing up, my calf just below my knee measures 16"
      my knee center measures 17-1/2"
      my thigh, just above my knee measures 18-1/4".
      what size do you recommend?
    • Unfortunatley you will not fit into a medium so you would have to try the large size
  • Emily at 1/30/2016 11:35 AM
    • Would you suggest this brace for a runner who had ACL, MCL and LCL reconstruction? I'm training for a marathon and my current brace is not doing the job. I saw there is a different brace for just ACL but this one seems more for a runner rather than a contact sport athlete.
    • It depends on when the ACL was reconstructed. If it was more than a year ago then a hinged knee support such ans the Bionic Knee would be sufficient for your knee. Anything less than as year should be a rigid knee brace to protect the still healing graft.
  • Daniel Franz at 1/27/2016 9:22 AM
    • I had a surgery on my knee. Arthroscopic surgery seemed help a bit but have come to realize it is mainly arthritis. I need a knee brace for everyday activity and SKIING. Can you narrow down which products to choose from? $$$ to $$. Thanks
    • It depends on how much support ou want. The OA reaction Web knee brace will offer mild offloading to the OA affected compartment and is light wieght and low profile. http://www.betterbraces.com/donjoy-oa-reaction-web-knee-brace
      For more support and a rigid knee brace the OA Adjuster 3 is a stronger frame and provides support for moderate to severe OA.

    • I've been diagnosed with a small Acl tear in my left knee. I fortunately have no pain, although I sometimes feel a little instability and fatigue after walking for a few hours. Presently, I'm doing a lot of leg strengthening with PT and barre class and just using a compression sleeve to remind me to be cautious. My main concern is with support while golfing and walking distances (like while touring on vacation or using a push cart while golfing). I'm pretty sure the playmaker 2 w force point is the recommended brace, but my preference is to use a one with a shorter sleeve, (Bionic or deluxe hinge?) as my inseam is about 28. Would a shorter sleeve brace provide enough support? tHanks for your advise.
    • The shorter sleeve brace will provide medial and lateral support to your knee but not much support to the ACL. If you want to do a shorter sleeve I soul suggest the Deluxe Hinged Knee since is has a stronger hinge than the bioinic

    • Coming off from a moderate MCL sprain and looking to get back into competitive tennis ASAP. Based on description, the Bionic brace seems to be the best choice for rehab and returning to play. My knee measurements are 17.5 thigh, 14.5 kneecap, and 14.5 calf. Would you recommend this brace and what size do you think would be best, the small or the medium? Thanks.
    • Yes this would be a good choice for a suportive brace and I would suggest the small

    • Grade 3 year mcl, ACL torn & meniscus tear. Rehabbing knee, mcl healed but loose and knee unstable. Need to strengthen and wondering if this brace will provide enough support for everyday use, weights, running and eventually motorcycling.
    • Your going to need a brace that will offer at least moderate support. The Playmaker II with the FP hinge will provide support for all of the structures that you have injured and should be sufficient for everyday use and light activity.
      http://www.betterbraces.com/donjoy-playmaker-ii-fourcepoint.
      If you want to do more strenuous activites you should go with a rigid knee brace such as the Don Joy Armor with Fourcepoint hinge

    • I have had problems with mainly my left knee for 4 years now. I lift weights and when I went down into a squat my knee gave out and I had extreme pain. I saw knee specialist and I had a tiny tear in my meniscus along with my patellar not tracking correctly and overuse. I need a new brace to continue lifting weight and be able to do such things as deep squats. Would this brace allow me to bend all the way and give support?
    • I would suggest the Reaction Web Knee brace http://www.betterbraces.com/donjoy-reaction-knee-brace for support around the kneecap and that meniscus tear you have. The brace is not as thick as the Bionic Knee Brace and you should be able to bend better with the Reaction.

    • I am using a Bionic my right knee when playing basketball for torn meniscus/mcl, and am happy with it. I am tentative with my left knee, however, out of worry of having the same injury I experienced with my right knee, and am thinking of getting a brace to support it. Would it be appropriate to get a bionic, so both have the same support and restrictions, or something lighter like a Performer?
    • Will
      I would suggest getting another Bionic for the right knee. It will provide the same stability that your left knee is getting

  • Alex at 10/31/2015 6:30 PM
    • I hyperextednded my left knee when a fork lift pinned me to a wall. The force exerted on my knee tore my medial meniscus. When the surgeon went in to fix the tear, it was already healing, but he noticed that my petallar tendon was damaged. i've been reading up on this brace and it seems to be able to work to help with the stability of my medial meniscus during sports and weightlifting and prevent hyperextension but will it be able to support my tendon as well or will something else work better for that. Honestly, I think I'm more worried about my knee locking/buckling and hypertension during sports activities like martial arts.
    • Alex
      The Bionic Knee Brace will be proper support for the things you would like to do. The brace provides both medial and lateral support and the hinge should help prevent mild hyper-extension. Another option would be the Playmaker II Knee Brace. this brace is a step up from the Bionic Hinged. The hinge on the Playmaker can be adjusted to prevent more serious hyper-extension.

    • Matt
      You will need to get a brace that has the ability to limit extension of the knee. The Bionic Knee will not do that. The Playmaker comes with metal stops that can be installed into the hinge that will help with your hyper-extension. http://www.betterbraces.com/donjoy-playmaker-knee-brace

I wear a supportive brace similar to this for support but it is not performance based. Would this brace limit the chance of re-injury in high active sport like soccer??
    • Kyle
      The Bionic Knee Brace would be a good choice to wear for soccer. The brace will provide general support to both medial and lateral sides of the knee and help to prevent any twisting injury.

    • My son is 16 yr old and he had surgery for torn ACL in April 2015. He is Rehabbing it know. The doctor believes we will be close to full recovery by Dec 2015 to wrestle with a required brace. I do not feel comfortable for him to wrestle this soon without support. In addition, weight is a concern, as the state he wrestle requires that any brace used by a competitor most be weighed in with the wrestler. His current brace is 1.6 lbs and requires additional sleeve to wrestle as it has metal bars. Can you advise if this brace will give adequate support and the weight of this brace. Also if you have suggestion of other braces that would be better fit for this use.
    • Mike
      The Bionic Knee Brace would not be adequate support for your son. You will need to go with a rigid knee brace and the lightest one we make is the A22 Knee Brace. The brace is custom made and weighs 19 oz. The brace would need to be worn with a brace cover which is neoprene. http://www.betterbraces.com/donjoy-a22-titanium-custom-knee-brace http://www.betterbraces.com/donjoy-sports-brace-cover

    • Hi. What is your recommendation for a knee with no cartridge under my knee cap. My knee also tracks incorrectly. I've had injections and am way to young for a replacement which I don't want and will do everything to avoid. I'm a cyclist and a fitness instructor so I need something that can handle sweat.

      This brace will provide you with both medial and lateral support of the knee, but very minimal ACL support. If you would like a brace that offers more ACL support as well as medial and lateral support I would suggest the Playmaker II http://www.betterbraces.com/donjoy-playmaker-ii-knee-brace

    • John
      The Bionic Hinged Knee Brace will help with the side to side movements and stability of the knee but may not take all of the pain away. Try looking at the OA Reaction Web Knee Brace. This brace has a singe hinge that will be on the inside of the brace and will offload the lateral compartment and help with that pain. http://www.betterbraces.com/donjoy-oa-reaction-web-knee-brace

      Either brace is appropriate for your injury and playing soccer. The bionic hinged knee is a shorter brace with a economy hinge.

      Because of the measurement of the knee center and calf you will have to go with a large size although your thigh measurement is in the small range.

      The bionic Knee brace will provide both medial and lateral support of the knee and would be the better brace if you feel a little instability. The Web knee brace offers more support to the front of the knee and pain relief but does not have that medial and lateral support. Hope that help s with your decision

    • Anthony
      A better choice would be the Tru-Pull Lite knee brace. this brace is for someone in your situation who suffered a patella dislocation. The brace will keep the patella tracking in the correct position and provides both medial and laterl support with bilateral hinges. http://www.betterbraces.com/donjoy-tru-pull-lite

    • Brad
      The bionic knee brace would not be sufficient support for your sons knees. Since he is only 8 months out after sugery the rigid knee braces are the correct braces for him. If you are having fit issues you may want to see if you can get the braces adjusted by the practitioner that dispensed them to you

      You can wear the Bionic Hinged knee in the water, however it is neoprene so it will be a little heavy. Possible the Reaction Web Knee Brace would work for your knee while swimming as it is lower profile. http://www.betterbraces.com/donjoy-reaction-knee-brace

      I do believe a hinged knee brace such as the Bionic Knee would be the correct brace for your son. The brace will provide support of the knee and the neoprene material will also provide the compression that he needs

    • I ruptured my patella tendon in my left knee almost 3 years ago and it's never been the same. I recently began working out again and I'm looking for the right brace for my knee. I do a good amount of cycling, rowing and elliptical work. Would this work for me?
    • Joe
      The Bionic Knee will provide general knee support because of the bilateral hinges that are on the brace. The front has a padded opening for your kneecap and should provide some support for that area. You might also want to looka at the Webtech Knee Brace. http://www.betterbraces.com/webtech-knee-brace This brace doesn't have the hard hinges but will provide more support for the front of the knee. If you have any pain from that tendonitis this brace will work better at deccreasing that pain while working out.

  • Alicia Curry at 9/4/2015 9:06 PM
    • Hello, I was wondering if the " Bionic Knee Brace" will a great suite for me. I'm a 6'5 210 forward/Center who recently just returned to the court for basketball. However my (Right Knee) has been bothering me. I torn my ACL in the 10th grade and was misdiagnosed and later had surgery 2 years later after the injury in 2011. I've been back hooping since 2012 never really had an issue about my knee besides my quad muscles and leg being weak so I worn a brace while playing here at my college.

      Unfortunately that problem has crawled back on me. Lately I've been experiencing pain in my Right knee in the lower front on the left bottom side. I also have a little swelling and fluid on the right side of my knee. I also been experiencing pain in the back of my right knee as well. I've been doing a lot of running and jumping and it's my year back. The doctors said my ACL is still intact and so is every other ligament. What do you think is the problem "Would you recommend this brace for me ? I had the patella tendon surgery and I was also told I had some lateral meniscus tears that was fixed. I never had a problem with my knee until now. I'm very athletic I run and jump a lot and that's when the problems and swelling started to occur. Can you please help me pick out the right brace for this season.
    • Alicia
      The Bionic Knee Brace will provide medial and lateral support to the knee as well as compression. This may be all you need since you doctor told you there was no problem with your ACL. I would suggest trying this knee brace when you play basketball.

    • Chuck
      The Bionic knee is a neoprene hinged knee wrap and will offer medial and lateral support. I would like to suggest instead the Webtech Knee Brace instead. This brace is very light wieght and will support the anterior knee very well as well as mild OA in the knee. If might work better for you than the hinged knee brace. http://www.betterbraces.com/webtech-knee-brace

    • I have had several left knee procedures including an ACL reconstruction. My latest MRI has revealed the ACL has once again ruptured and I have been advised, because of my age (58) and the number of procedures to have a knee replacement. Considering not to opt for the replacement...which brace would be best for everyday use?
    • Michael
      What brace you should use depends on what you want to do in the brace. If it is for daily activities and no strenuous activity then the Playmaker II fourcepoint hinge would be appropriate. http://www.betterbraces.com/donjoy-playmaker-ii-fourcepoint
      If you want to exercisea and do more strenuous activities you will need a more rigid type of knee brace such as the Full Force Ligament knee brace http://www.betterbraces.com/donjoy-fullfource-ligament-knee-brace

    • Richard
      If you want your sone to wear a brace but do not want to purchase a rigid knee brace, I would reccommend the Palymaker II knee brace. The playmaker II will still provide moderate support for all of the major ligaments of the knee. http://www.betterbraces.com/donjoy-playmaker-ii-knee-brace

    • My son had acl reconstruction surgery last year. He is playing football this season in the safety position. Will this be a good brace for protection?
    • The DonJoy Performance Bionic Knee Brace is better suited for everyday activity, and wont offer much protection from injury while playing a contact sport like football. For more protection and support the Armor Fourcepoint is suggested, and highly recommended for use during football.

    • I have already had one ACL reconstructive surgery on my L knee and just recently, since I've upped my exercise/HIIT training, I've noticed my R knee beginning to slip, just how the L started. I thought the Performance sleeve would be enough, but a) it's too large (I bought a Small, I"m 13", so not sure why it doesn't fit) & b) offers absolutely no support against hyperextension, which is the direction my knee tends to go. This bionic brace sounds like a better option- I think it even said it has hyperextension stops. I am worried about getting another Small and it fitting too loosely. I understand it velcros in the back for various sizes- just trying to prevent another return for both our sakes. ;) Any suggestions/do you think this is a wise choice for stabilizing my knee during HIIT workouts? Thank you!!


    • The BIONIC KNEE BRACE would be good option which gives you the bilateral hinges to fully stabilize the joint against lateral forces while operating freely doing your training and exercises. It will give you the mild support. There is also the DONJOY DELUXE HINGED KNEE BRACE giving you the moderate support from instability of ligaments, sprains and injuries.

    • Any hinged knee brace will work for that condition. The Bionic is a thicker neoprene than the Playmaker or PlaymakerII. I would suggest the Playmaker II knee brace as an alternative. The brace will be cooler to wear and lighter, with a little more support than the Bionic provides

      Yes the DonJoy Performance Bionic Knee Brace will prevent hyper extension. The bilateral hinges will help control your extension to prevent the knee from hyper extending.
  • Timothy Sadowski at 7/1/2015 10:10 PM
    • I am 5 foot 8 inches tall about 260 so I am pretty big for a small statue and really would like the to know if the extra large would be the right fit for me with the Don Joy performance bionic knee brace. I have a torn acl in my right knee and think about having in fixed in the near future and was wondering why this brace doesnt come in larger sizes for the simple fact I dont know if x large will work for me.
    • Hello Timothy!

      Thank you for contacting Better Braces. The measurements are based on the center of the knee circumference so you would have to measure the the center of your knee. The extra large fits a person with a knee circumference of 17 inches to 19 inches. Unfortunately those are the only sizes the DONJOY PERFORMANCE LINE comes. The BIONIC KNEE BRACE gives you mild support compared to the rest of the DONJOY line.

    • What material are the hinges made from? How thick is the brace at the center of the hinge? Would this brace be suitable for daily wear (I walk and stand quite a bit at work) or is it recommended only for moderate to light exercise activities like at the gym or during hiking? (I use Playmaker II brace for skiing only.)
    • Hello,
      The hinges in the DonJoy Performance Bionic Knee Brace are made out of a aircraft grade aluminum. At the center of the hinge it measures approximately 1/2 in thick, at each side. The DonJoy Performance Bionic Knee Brace is perfect for everyday use, as well as use during sports and exercise . The perforated neoprene will help keep you cool and comfortable when your out hiking and being active.

      I like your products and your prices are very reasonable!
      Thank you
    • Liz
      This brace has two hinges so it will give medial and lateral support as well as patella support. It will be a good brace that will give general support of the knee. There may not be a need to wear a sleeve underneath

Great brace. If I'm awake it's on my knee. Gave it a 4 because of the price. For someone who wears it for activities it is a great value but if you wear it all the time it wears out faster. I have to replace it about every 3 months.

My first brace was great. Just a tad too small though even with the right measurements. I reordered another brace same color with the lime green (I was out of the 60 or 90 day window) and I have not received it since it I guess was in back order and then they said it was not being shipped so I guess I will have to reorder or just plain black which I did not want :( All in all no bad review for any of the braces I ordered from this company.

Runs very, very small. I originally purchased in medium as that was the size I was using for the OA Reactive brace. The medium did not even make it around my thigh even though the measurements were for medium. So I immediately ordered a large it was just as small.
