Stabilizes The Kneecap To Help Prevent Dislocations And Help Alleviate Pain

The DonJoy Lateral J knee brace is one of our most popular patella stabilizing brace. The brace is equipped with a tubular, lateral "J" buttress that runs alongside the knee and provides support against lateral patellar subluxation, dislocations, or improper patellar tracking. The Lateral J can be worn during day-to-day activities, as well as sports and in water.

Drytex or Neoprene? Drytex is DonJoy's exclusive solution for patients with neoprene sensitivities or those who prefer less warmth from their bracing. Constructed of a unique patented nylon core and polyester Lycra fabric, it allows for improved airflow while still giving ample support and compression. Perfect for people in warm weather climates and those with neoprene allergies or irritations. (Photo images are of Drytex material with seams. Neoprene material, not shown, does not come with seams). Neoprene is a thicker material that will provide more warmth.

With or Without Hinge? This brace is available with a removable hinge for added stability for an additional cost. You should order the brace with a hinge if you have joint instability. It will provide more medial and lateral support. Otherwise, you should order the brace without a hinge.

• I am overweight and have been working out. While doing lunges and squats I hurt my knee. Since then my knee is noticeable and as the day wears on when I'm on it more becomes stiff and feels like it needs more support above and below the kneecap. I do use steps daily and have found going up isn't bad but coming down is worse remember I'm heavy. What brace gives best support?
• It sounds like you need a more general knee support brace, with hinges. The Lateral J is for patella instabilities. My suggestion would be the DonJoy Economy Hinged Knee. This gives medial and lateral support with a built in stop to prevent hyperextention. See the link for more details: https://www.betterbraces.com/donjoy-economy-hinged-knee

• I play soccer, but I play pretty rough both my right and left knee caps dislocat would it be good for me to get these braces
• Yes, if you have dislocation problems with your patellas the DonJoy Lateral J Patella Knee Brace will be a good fit for your needs.

• I dance and about 30+yrs ago I tore a cartilage on the left side of my right knee. I'm one piece I have to get on my knees which is hard to do because I can't stay on my right knee very long. So I need a brace/ pad that will give me stability and support. Can you help me please?
• The DonJoy Economy Hinged Knee, https://www.betterbraces.com/donjoy-economy-hinged-knee, may offer more stability and support for dancing, as the Lateral J Patella Knee Brace is designed more for patella stabilization.

• My son has patella subluxation to the left knee. He plays football and has to wear a brace. He had a brace but it kept sliding down during football. Which brace would be good for him for his knee, that will stay on under football pants and wont be uncomfortable for him.
• The DonJoy Lateral J Patella Knee Brace will help address the patella subluxation, while fitting under football pads.
George at 5/10/2016 11:17 AM
• I was born with very bony kneecaps that stick out and I have 3 to 4 patella dislocations a year. Even a slight twist causes dislocations. Would this help me?
• If you have many dislocations then I would suggest the Tr-Pull Advanced System Knee Brace. This brace is our most supportive knee brace for someone who dislocates the kneecap often. the brace comes with two different buttress the can be used and the straps pull the kneecap into the correct position.
Alison at 5/5/2016 5:53 AM
• I dislocated my kneecap badly in September of 2014. I've had a lateral release (which didn't work), then MPFL replacement/reconstruction surgery. The last surgery was in June of 2015. I've had a rough time with rehab, but have finally been cleared to play ice hockey again and am looking for a brace. My biggest issue is pain, but I also want stability. Is this brace the best bet for me?
• The Lateral J is a good option for you. The other option is the Tru-Pull Lite. This brace also has a lateral buttress for the kneecap and can be pulled to add support.

Scott at 5/3/2016 2:46 PM
• My patella is of center, I don't remember by how much. No injury, or surgery, just the occasional swelling. Can I wear the drytex lateral j patella knee brace all the time, or is it only for strenuous activity?
• The brace can be worn as much or as little as you would like. The brace can be worn by both athletes and non-athletes to help keep the patella tracking correctly
Steve at 4/6/2016 7:33 PM
• My daughter plays softball and having trouble with finding brace that fits comfortably under her pants. Will this brace? Or can wear this or any other brace over pants and still get support
• Yes this brace will fit under softball sliding pants

• How can I tell the difference from a "right" DonJoy Hinged Lateral J Brace versus a "left"?
• The "J" Butress in the sleeve goes on the outside of the knee
Chris at 3/25/2016 7:10 PM
• I dislocated my right leg kneecap which caused a medial patellofemoral ligament and medial patellar retinaculum tear. Had surgery on 3/2. I'm still in a full leg brace to keep it straight. I'll be starting physical therapy next week. Although, I do not play any contact sports at this point in my life (I'm 35). I do stay active. I'm looking for the best brace to use once I can get back to normal activities.
• The Tru-Pull Lite would be a good choice for you. The brace will help to keep the kneecap tracking in the correct postion and support the knee. The brace is a small brace, not too bulky and can be worn for activity.

Ashley at 3/21/2016 8:29 PM
• I ordered the small lateral J drytex brace. I play football and when I run or do anything super active my brace tends to shift from the upper thigh. I constantly have to move it back into the complete right fit for every play. It stays in place with my lower leg, just not the upper. Do you suggest a smaller size?
• A smaller size might help or a different brace such as the Tru-Pull Lite

• Question about sizing. I measured my thigh at 25.5 inches, knee 16, calf 16. I already have this knee brace I got from an orthopedic doctor over 10 years ago and it's a medium. I can get it on and it fits. What size should I order for my left?
• Your going to have to order the XL to fit the thigh
Jessi at 2/6/2016 8:35 PM
• I am currently using the Don Joy Tru-Pull Advanced system knee braces for both my left and right knees. Although I feel they do the job for help with patella tracking, I have to return them because the patella hole has too much pressure on the top of my knee cap (too much downward pressure as in my knee cap is being pushed more towards the floor rather than floating freely within the hole). This causes a lot of discomfort and I'm unable to flex my legs properly wearing the brace. My question is, how much downward tension does the patella hole on the Lateral J Patella knee brace have vs. the Advanced Tru-Pull?
• Try the Tru-Pull Lite knee braces. The hole for the kneecap is bigger than the hole for the Advanced system, yet still have the same pull

Brennan at 12/1/2015 12:40 PM
• I am a hockey goalie and dislocated my knee from a player falling on my leg during a game. As i said I am a goalie so I go down on my knees a lot so would this brace be good for me to wear while playing hockey again? And which material would be best to wear under my hockey equipment, drytex or neoprene?
• Brennan
  The lateral j knee brace would help keep your knee from re-injury. It should fit under your pads and allow you to move. The drytex material would be best
Skier, patellar tracking disorder at 11/14/2015 7:35 AM
• I have patella tracking disorder and, at age 55, get wobbly knees after a day a skiing. Which brace do you recommend for effect and comfort for 8 hour wear on the slopes?
• We have a few braces to choose from for patellar tracking. For mild tracking issues the Reaction Web knee brace is a good choice and it helps decrease any anterior knee pain you may have. For more severe tracking issues we have the Lateral J knee brace and the Tru pull lite. Both braces have support on the lateral side of the brace to help the patella track correctly. The Tru pull Lite is a shorter brace than the Lateral J

• My son is a 6ft 4 in 280 lb lineman he wears your knee braces to protect his mcl and acl and they worked !! How ever he did just dislocate his knee cap and they want him to switch to a jay brace . Does the hinge version of this do both protect the knee cap and mcl and acl ?
• Scott
  If you son wears our rigid knee braces you can order a accessory that will help the kneecap. The Tru-Pull Advanced Attachment is used with out rigid knee brace ans a lateral support for the kneecap, so he can still have the protection of our functional knee brace. http://www.djoglobal.com/products/donjoy/tru-pull-advanced-attachment The attachment can be ordered through Don Joy Direct at 800-336-6569
Kari at 9/12/2015 7:38 AM
• I'm right on the border for measurements between the large and medium, should i go large or medium? does the brace typical fit large or small?
• Kari
  In my experience the braces can run a little small so I would suggest going with the large.
MMS at 9/3/2015 5:25 PM
• My RT patella is positioned far lateral from center. Braces for people with center-aligned patellas simply don't work, as it sits on top of my patella rather than around it. Will this product will work for my patella tracking disorder?
• Either the Tru-Pull Advanced System or the Tru-Pull Lite would be a better option for your case.
  
  The Lite might be a good place to start as the buttress can be moved to sit on the lateral side of your patella instead of on top of it.
Tomeka Smith at 8/30/2015 10:44 AM
• My daughter is a competition cheerleader and she popped her knee cap out of place. Is this a brace that she could use while tumbling and competing?
• Yes, this brace would be appropriate.
Cheryl at 8/27/2015 5:17 AM
• My 12 year old daughter is a cheerleader and was recently diagnosed with <a href="http://www.betterbraces.com/knee-injuries/patellofemoral-pain-runners-knee">patella femoral syndrome</a> and requires a brace with lateral patella support for her left knee. It is important that the brace doesn't restrict her movement and she wants a brace that will do this yet be as short as possible. Her thigh measured 15" about 2" above the patella and about 17 inches 5-6" above. What would you recommend?
• I recommend the Tru-pull lite, to provides the most support for someone who has a patella that dislocates laterally. The brace is 9" in length and the shortest available. I recommend measuring her Knee and order the brace based off her knee measurement, since the brace is only 9" in length. This brace does run a little small so, if she's on the upper end of the size chart, order the next size up.
Michelle at 8/19/2015 8:48 AM
• My 15 y/o son dislocated his knee cap during <a href="http://www.betterbraces.com/football">football</a>. His positions are outside linebacker and wide receiver. I am looking at this brace and am wondering if I should purchase the hinges. The knee is stable with tenderness over his MCL. Would you recommended the hinges and what material?
• Yes, we would suggest going with the hinged version. This will provide more medial and lateral support and protection. For sports the Drytex material is suggested, it is a bit more breathable and comfortable.
Juliana at 8/8/2015 4:47 PM
• I'm in dance and I need a knee brace that isn't bulky and could potentially fit underneath my leggings. Would this be the right brace? I had <a href="http://www.betterbraces.com/knee-injuries/hyperextended-knee">hyperextended my knee</a> and dislocated my knee cap and need protection while l'm dancing.
• The Tru-Pull Lite, https://www.betterbraces.com/donjoy-tru-pull-lite is good for mild to moderate patella instabilities, dislocations, or tracking issues and should offer protection while dancing.
  
  
Bo at 2/16/2015 8:21 AM
• Would the hinge be a good idea if you also strained your MCL along with the kneecap dislocation?
• Yes, the hinges will protect that ligament.
Jeffrey at 11/28/2014 7:52 PM
• I am a long time ice hockey official and have been experiencing some right knee pain (knee cap) the past year. I will probably need a knee replacement one day. I had a synvisc/cortisone shot a few times that has helped but still have some discomfort especially when I push off from a standing position to follow the flow of the play. What type of knee brace would you recommend for this type of activity? Need something that is flexible and easy to put on before taking to the ice.
• I would suggest the DonJoy Reaction Web. This brace is light weight easy to put on and helps reduce anterior knee pain caused by patellofemoral pain.
kyrena at 11/19/2014 7:19 PM
• How thick is this material?
• 1/8th of an inch
Matt at 11/13/2014 6:49 AM
• My Doctor recommended a J brace or a C brace (She wasn't sure of the name) for my knee because my IT band is pulling my knee out of alignment. Which brace is going to do that for me?
• Matt
  The Lateral J Knee Brace will help with the problem you are having with your knee.
Tim at 8/9/2014 12:44 PM
• My daughter had a patellar subluxation about 16 months ago. She is now playing <a href="http://www.betterbraces.com/soccer">soccer</a> and feels the need for knee support. We are going to order this brace. How do we determine if she will gain additional benefit by having the hinges?
• You will only need the hinges if she has joint instability which, it does not sound like she has any. She does not need the hinges if her only issue is patella subluxation.
Chandni at 7/10/2014 1:40 PM
• I have dislocated the same knee three times in the last 10 years, and I'm only 21. I am a dancer and cannot imagine my life without dancing, but my doctor says if it happens again then I'll have to get surgery to tighten the ligaments that hold my kneecap in place, because both kneecaps are very loose (it's a wonder this hasn't happened to my other knee yet). My PT suggested this brace for dancing in the future, so I just want (1) to verify if this is a good choice, (2) are the hinges a good addition for my situation, and (3) what the two materials are like and how they differ.
• 1. Yes, this brace is appropriate for someone who has dislocated the kneecaps
  2. I would suggest that you do not need the hinges, they are only needed if you feel you have instability in the knee joint
  3. Neoprene is like wetsuit material and drytex is similar but more breathable and not as hot
  4. This is a great brace for dancers.
Ben at 3/7/2014 9:53 AM
• Hi, I've dislocated my knee cap a few times and recently chipped the patella as well. My doctor said that chipped spot will grow back with weaker fibro cartilage as the stronger original hyaline cartilage will not grow back. I'm looking for a brace that will prevent future dislocations and also protect the fibro cartilage from chipping, is this J brace right for me?
• This a good brace to prevent further dislocations. Another choice is the Tru-Pull Lite. It is a shorter brace not as hot and gives a little more control over pulling that kneecap into the correct position. Either brace would be a good choice.
Sue at 3/4/2014 6:42 AM
• My 11 year old daughter has dislocated her patellar twice during dance due to patellar tracking/groove issues. The doctor had prescribed an xs Breg PTO brace, but the hinges are too restrictive for dance and she cannot wear it. Do you have any other suggestions for something lighter that has a j or buttress to keep the knee cap tracking properly, but still allow for less restrictive movement such as a dancer would need.
  
• This is a great option for your daughter's diagnosis and will provide the stability she needs for dancing without impeding her motion.
Richie at 2/19/2014 6:14 PM
• Two and a half years ago, I dislocated my kneecap playing football. I went through PT and wore the Tru-Pull Lite brace. About 6 months later, I dislocated my kneecap again while playing indoor soccer with the Tru-Pull Lite brace on. After that, I switched to the Breg PTO Soft knee brace and have had no knee issues since while wearing it during 2 football seasons and 1 lacrosse season.
  
  Now, 2 years removed from my last dislocation, I am considering trying out a lighter knee brace because I have not had any knee dislocations or subluxations since but am still uncomfortable playing sports without a knee brace. My biggest concern with this J brace is if it really does keep sufficient pressure on the lateral edge of the kneecap when the leg is fully extended. Can you verify this? Also, how does this brace compare with the Breg "Lateral Stabilizer Soft Knee Brace"? Is one better than the other?
  
  Finally, which material would be better to get, Drytex or neoprene? Does one material tend to slip more than the other?
• The Breg is similar to the Lateral J, both have the same mechanism. If you would like a brace for extremely active people that will keep constant pressure on the kneecap you should look at the Reaction. It will keep the kneecap tracking in the Femoral groove, it has a teflon infused elastomeric web that as you flex it will get stronger to keep continuous support on the kneecap.
Christian at 1/25/2014 9:03 AM
• I've had a 3 knee dislocations spaced about 7 years apart. All where caused by slip and falls where the knee cap displaced to the lateral side and corrected itself in the same action. My PT suggested that my quads are pretty weak, and have since been training them.
  
  I've had an MRI and nothing out of the ordinary has been found. I've also gone through rehab, but still I have some clunking/clicking occasionally in the knee along with pain and swelling.
  
  My PT originally suggested a <a href="http://www.betterbraces.com/knee-braces/knee-sleeves?material=100">neoprene sleeve</a>, perhaps with some stabilizers for use in my kickboxing class which I have not been attending of late.
  
  I am currently using a Bauerfeind GenuTrain, but find that it causes more problems than helps pushing on the kneecap.
  
  After the injury, I originally purchased the "Shock Doctor Ultra Knee Support with Bilateral Hinges", which my PT said was way too restrictive and much more than I needed.
  
  Do you think this brace with hinges would be a good fit for me?
• The Tru-Pull Lite is better than the Lateral J because the buttress can be positioned right at the end of the kneecap so you can control the tension against the patella.
Kumaran at 1/24/2014 6:44 AM
• I had a ligament tear/stretch on my left knee some 8 years ago. I did not go for the surgery.
  I don't have any problems with normal day to day activities. But do feel the instability occasionally when I play cricket, which makes me fall. Please suggest a suitable brace which has no bulk and will give support on the sides and allow me to play freely.
  
• This brace is primarily used for Patellar instabilities. If your instability is the patella this is a great brace. If your instability comes from ligaments you may consider looking at the DonJoy Deluxe Hinged Knee.
Charley at 1/21/2014 6:22 AM
• Hello, I have dislocated my knees a few times over the years, the last time 3 years ago getting on a ski lift when I was snowboarding. I keep very fit and don't get a lot of trouble from my knees. The odd slip here and there, I have used the DonJoy Tru-Pull Advanced braces for the past couple of years when I go <a href="http://www.betterbraces.com/snowboarding">snowboarding</a>, they have been great in respect to my knee not dislocating but when it comes to comfort they are terrible. I don't use them for anything else just boarding. Do you think if I swap to these they will still be as effective, but a lot less bulky but still give the same results?
  
  
• This is an excellent choice for patellar stability. This brace will be more stream line and along with the lateral support you received from the Tru-Pull Advanced brace you will also receive inferior patella support.
Andre at 12/26/2013 9:41 AM
• I have had multiple patella dislocations over the last 20 years, it first happen while skiing, then it repeatedly happened while skating, playing hockey or making a false movement. I have met one of the top knee specialist here (Montreal) and had a bio-mechanical test perform, basically there is not much to be done beside working to strengthen my quads. The knee cartilage is bit worn and also have osteoarthritis of the knee. Ironically I don't have real pain or nothing that prevent me from running, biking or practicing karate weekly. The Dr says, I need to manage my human capital until I get older and get a total knee replacement surgery. I have always practice sport and I can't get the idea of no longer skiing, skating or playing hockey for fun. I had stop practicing those sport for few years but even though my knee cap would dislocate in all kind of situation. Last year, after training hard for 2 months, I went to ski a couple of time and my knee hold-up fine and had no pain, but I know dislocation will happen sooner or later no matter how careful I am and whatever I do. We only have one life to live and I don't want to live mine sitting in front of a TV set. I was suggest to buy a knee brace that will give me the extra security I need to practice my preferred sport. I am now very careful in ski, ( no more double daffy or 360 if you see what I mean), I only play hockey and skate in a non competing mode, just for fun. I'm thinking of ordering this brace with hinge, do you think this is the best brace for me?
• Since you have had multiple dislocations I would suggest our best patello-femoral brace for that which would be the DonJoy Tru-Pull Advanced System.
  This brace will help keep the patella tracking in the right position. The material of the brace is Drytex breathable material and you can get it with a hinge to give added medial and lateral support.
Mary claire at 10/26/2013 10:01 AM
• I had an ACL repair 2 years ago and I would like to start playing cutting sports again. I have developed a patella tracking issue since my surgery and my doctor suggested this brace. I am nervous to buy this brace since it is not for ACL support and I will be playing cutting sports again(recreationally).
  
  Will this still support my ACL?
• This brace does not give support for the ACL, only patella tracking and if you get the hinged version that will give you some medial and lateral support. The Playmaker II with a patella donut would be a better choice. The Playmaker has our four-Points of Leverage strapping system that we use on our rigid ACL braces. The strapping creates the right kind tension to protect the ACL. The other option is one of our rigid ACL braces with a Tru-Pull Attachment for your patella.
sierra at 9/4/2013 9:16 PM
• I have this brace, was wondering if there was something smaller with the same support ? Also would really prefer if this brace came in tan.? I hate having to wear such a big brace and it being so noticeable. I have dislocated my left knee two times so think this is the best support ? I have read you have total mobility with this brace however I can't seem to bend my leg only to barely walk without a limp.?
• We do not have a tan brace that would help with your patella issues, however, the Reaction is a lighter lower profile brace that would keep that patella tracking efficiently or the Tru-Pull Lite is a lower profile less bulky patellafemoral brace.
Andrew at 6/6/2013 7:04 PM
• I had an ACL repair roughly 6 years ago, and a torn meniscus about a year ago. Most recently, my patella began to sublux occasionally. I'm looking for a brace that will support the patella and provide overall knee stability without being too bulky. I'd also like something that I could wear during sports. Currently, wearing it every day wouldn't be the norm...but it may develop into that as my knees get worse (at that point I would look for a more suitable everyday brace).I've basically narrowed it down to the Reaction and this brace. Which of these two braces would more fit my requirements? Or possibly a different brace?
• This brace would be a good option for you, the J buttress provides support to the patella and the length of the brace provides compression and support to the knee.
  
  You have one more option for a Patella Stabilizer. The Tru-pull Lite, provides moderate support and is a smaller brace about 8 inches in length.
  
Cynthia at 5/29/2013 12:03 AM
• I have medial and lateral patellar subluxation, though it is more pronounced in the lateral direction. I don't want a bulky brace and the J shape looks like it might provide the minimal medial support I need. I'm sensitive to neoprene so the drytex alternative is a plus. Is this brace a good choice?
• Yes, the J Brace is a great option for Lateral Patella Support. Another option you may consider is the Tru-Pull Lite. It's a low profile brace, the shortest Patella Brace we have. Provides both medial and lateral support. Click here.">https://www.betterbraces.com/donjoy-tru-pull-lite">here.

• Do you make a waterproof patella knee brace- My daughter is a swimmer and requires the brace to be streamline and water resistant. Do you make one?
• All of our braces can be worn in the water. Garret McNamara professional surfer wears our braces. The brace will have to be rinsed with tap water and should be air dryed.
Don Gentry at 3/31/2012 6:27 AM
• I have this brace in drytex and would like to know how to clean it. Can I just put it in the clothes washer on gentle cycle? I have had it for 6 weeks and it needs to be cleaned/washed.
• Wash with mild detergent and let it air dry.
Carol at 11/30/2011 4:19 AM
• My son is a wrestler and needs a brace to support his patella. His current brace only allows him to bend 90 degrees. Will this brace allow him a broader range of motion?
• Yes, this brace will allow him full range of motion while supporting the lateral patella tracking problems.
Beau at 6/27/2011 2:13 AM
• Hi. I recently got the tru pull advance system for my knees for basketball..but the braces are just way to bulky and always are slipping down and the bands go over my knee..I saw this it looks like a much more active and light brace with great support..would this help prevent patella dislocations just as well?
• The Donjoy Tru Pull Lite or this J Brace would be more low profile than the Tru Pull Advanced System and still prevent lateral tracking and dislocations of your patella. Please let us know if you have any further questions.

• Have used the tru pull lite but still had some minor dislocation. Will this J brace provide more support of the knee cap?
  Daughter wants something with more support. Will this hinged product provide that?
• I would suggest doing the Tru-Pull advanced system, you can do it with or with out hinges. This brace is going to provide the highest level of patella support.

good knee support

Reviewed by: shawn
Verified Purchase

I've been wearing these braces on both of my knees for about a year now. My kneecaps don't track well, and they provide stability and compression. I've used both the drytex and the neoprene, and while the drytex doesn't make me as sweaty, if I'm doing anything other than standing (i.e. walking, hiking, jogging, etc.), the drytex braces almost immediately start shifting, which makes my kneecap fall out of range of the active part of the braces. The drytex braces also stretch out pretty quickly, creating a need to buy a new brace. So I'd recommend the neoprene braces for anyone who's active at all.

Great knee brace for its price!

Reviewed by: Victoria Benson

I have been using this same style brace since I first dislocated my knee cap 8 years ago. I am pretty rough on it and it holds up well. I have no problems with my knee cap as long as I wear it. I really like the fabric because the brace stays up even when it gets wet. The seam up the back is uncomfortable at times, but it is one of the few braces that I can find in this price range that stays on while I am playing sports.

Great brace

Reviewed by: Jackie

After dislocating my knee cap, I wore another brace that was difficult to move in, this is the most comfortable brace I've ever worn, and it allows me to do my PT without worry of my knee cap moving. I love it.

Functional, but uncomfortable

Reviewed by: Janie

This brace does what it's supposed to do, but it's really quite uncomfortable. The seam up the back is extremely annoying and the raw edges on the velco tabs are scraping up my other leg.

Standing for long periods, etc., have definitely become less painful since purchasing the brace, but I find myself having to weigh whether it's worth the discomfort of wearing it.

It's AMAZING

Reviewed by: Megster

this one brace I got NOT from your company was horrible it gave me pain and I couldn't bend my knee and it was over $100 it was a rip off and we think it gave me osteoporosis

now this brace is FANTASTIC very easy to run and move around in can bend your leg and sometimes I forget that I'm even wearing a knee brace it's awesome I've been using this one for about 6 months Love it I use it because I fully dislocated my left knee playing basketball and tore a few ligaments has great support I'm getting ready to order 2 more one for my right and one for my left my orthopedic Dr. recommended doing so for basketball and softball since it can easily happen to my other knee... the reason I'm ordering another one for my left is because I had to wear it for a few months until my knee stopped giving out on me and for PT and sports Its still in really good shape just ordering a new for when school starts for sports takes about a week or two to break in I HIGHLY RECOMMEND THIS PRODUCT

Extremely Pleased

Reviewed by: Runner

I bought one of these roughly eight months ago for my left knee. I had a severe knee cap dislocation eight and a half years ago and didn't have surgery. I was looking for a product with more support than the McDavid bands I had been using (which really don't do very much). I was looking for elements of a sleeve and a brace that allowed me to move around. This product does both extremely well.

I am currently training for a half marathon and have been running 15-25 miles per week. It takes some getting used to, but the product provides the compression of a sleeve and the medial and lateral support of a brace without being overly bulky. The J padding and straps keep my kneecap completely still. The pain while running is reduced significantly and my bad knee can still be sore after a long run, but I figure everyone is different in this regard.

A few notes: (1) Running a lot with one brace became a bit uncomfortable so I bought the same brace for my right knee. With only one brace on, my left leg was doing something different than my right. Over time, it got annoying and I was afraid I was going to injure myself. Although my right knee has no ailments (other than a shallow trochlear groove, as is the case with my left knee as well), I found the identical brace on my right knee to be the perfect solution. Doing interval / sprint workouts takes some getting used to because your range of motion is decreased a bit, but I still make it work. (2) Pull the sleeve up your leg enough so that the curve of the J pushes / nudges up against your kneecap. (3) I'm not sure how well this product will work during sports that require a lot of sprinting / shorts burst or changing direction. I've been playing competitive co-ed touch football for over two years. I tried playing middle linebacker and receiver with my brace for one game. I felt too slow and haven't worn it sense, even though I really know I should. Tackle football (high school and below), depends on the position. Basketball might be the same senario as football. Soccer you might be able to get away with wearing it. Hockey, you absolutely can wear this. Baseball, not sure.

Overall, this product (on both knees) allows me to feel confident enough to do a ten week training regimen leading up to running a half marathon. If my injured knee holds up, this product will help me run a full marathon in six months. For the record, I'm not a doctor, so this review is my opinion only and extremely unscientific.

Great for athletes

Reviewed by: Naomi

This is my daughters second Donjoy J Lateral brace. She wears it for Cheer and tumbling and it has helped with her knee pain and has helped keep her knee cap in place. So far her only complaint is the Velcro straps do irritate her other leg from rubbing. Also the shipping was faster than expected even during the holidays.

Pros: Quality product

Cons: Velcro straps irritate the opposite leg.

if the brace was able to stay in place it would be fantastic

Reviewed by: Beaver

After my knee cap dislocation due to patellofemoral grooves which were found to be shallow allowing my cap to dislocate with any lateral force doing ligament,tendon and muscle damage as well. I found that the brace moves around with light exercise or movement needing constant adjustment however when it is in the proper place over the knee cap it is comforting and provides the necessary support to keep the cap in place.

Quality

These were working wonderfully for about a week until the stitching started to come undone on the left brace. Not sure what I could have done differently to have prevented this from happening - was not being rough with them. For the price I expected better quality. I have RA and was planning on using them for a lot longer.

I have both material versions of this brace and I like this one better. It "moves" less on my knee while playing volleyball and is much cooler. The neoprene really makes my leg sweat and this one does not.

Pros: stays in place better than neoprene sweats less than neoprene version

Cons: tighter fit than neoprene version, but I still wear the same size harder to get on and off than neoprene, but not impossible I still prefer it to the neoprene version
