Product Description

Features & Benefits:

Four-Points of Leverage Dynamic System

You get the benefits of a lightweight and low profile knee brace that is also strong, thick and stable.
Swiveling, Internally Mounted Strap Tabs
Get a perfect fit by molding the brace to your knee, as well as enhance the fit and suspension of the brace with the swiveling strap tabs.

A Lightweight Brace That Provides ACL Protection

The DonJoy FULLFORCE knee brace is for protecting the ligaments of the knee, especially the ACL, from injury.

The FULLFORCE is most commonly worn by competitive athletes who suffer from any of these conditions, can't afford to be weighed down by a heavy brace, and are not trying to prevent contact or impact related injuries (like a football lineman might want to do).

This knee brace is designed to provide complete protection of the knee for competitive athletes.

who are at the greatest risk for injuring their ACL. Utilizing DonJoy's 4-Points-of-Leverage system and the FourcePoint hinge, knee instabilities are continually corrected. This means an injury doesn't have to occur for this brace to work - it significantly decreases your chance of getting hurt in the first place!

    • Hi!
      We'd like to but FullForce brace for my husband who has an ACL tear. His measurements are 38 cm (knee center) - 54 cm (thigh) - 40 (calf) so it's a border between M and L for a knee center and calf and L for a thigh. So is it better to take L or M in this case? Won't L be too loose?

    • It would be best to order a Large, according to the measurements you have provided.
  • Tony at 9/9/2016 12:30 PM
    • I currently wear I think it's a AFO what it does is keeps my knee from hyperextending it fits from just below the back of the knee down to under my foot will any of the braces you carry work for me
    • The A.F.O. brace we carry fits more from around the shin to under the foot. https://www.betterbraces.com/procare-super-lite-a-f-o

      We do not have an AFO that comes up to the knee and also prevents the knee from hyperextending. You would need to wear a separate knee brace along with the AFO.

    • Is the full force ligament brace available with a short calf to work with ski boots?
    • Thank you for contacting Better BRaces. This brace is available with a shorter calf option. When ordering you'll want to make sure to select short in the calf option drop down menu.

    • I have a daughter 12 years old that is into competitive wake boarding. As she has begun progressing into inverts and spins I worry about her knees. Do you recommend a full force knee brace for the prevention of injuries?
    • Yes, the DonJoy FullForce Ligament Knee Brace will provide support and protection, and works well with use in water sports.
  • Ajeet at 6/26/2016 3:47 PM
    • My father who lives abroad had bilateral knee replacements 15 years ago, it seems the PCL was sacrificed during the procedure, he is not a candidate for repeat surgey, it his left knee, it is unstable with problems of hyper extension, what brace would you recommend, he is 5.6/175 lbs, his measurements are medium across knee, and small above and below, something light that he can take on and off easily
    • Our DONJOY FULLFORCE LIGAMNET KNEE BRACE would be a great fit for your father. The brace is constructed out of aluminum which is light, would allow for easy mobility and easy to put on and remove. This semi rigid brace will provide great support, stability and will prevent any hyper extension. please see link below: https://www.betterbraces.com/donjoy-fullfource-ligament-knee-brace
  • Allie c at 6/22/2016 6:30 AM
    • Is this brace effective when worn over pants? I am a healthcare provider and this does NOT Fit under my scrubs. If it is still effective over a scrub type pant, I'd prefer to wear it that way than have to purchase an entire new set of uniforms.
    • The FullForce Ligament Knee Brace may be worn over pants, but you may have issues with it slipping, as it is designed to be worn directly against the skin.
  • Kyle at 4/26/2016 11:17 AM
    • If I need to bend the calf section of the brace out to alleviate pinching as my thing and knee are a large and my calf is an XL. I purchased the brace already but am very weary of bending the aluminum. Any advice or tips or should I just brute force the section that is pinching?
    • Yes the brace can be molded to fit better and it should not damage the brace in any way
  • Nikki at 4/23/2016 8:46 AM
    • My 14 you son haa had a partial menisectomy and repair to the right lateral.The cartilage over the bone is torn due to unalignment of the bone. It cannot be reapaired.I thought the OA adjuster would be beneficial because he plays basketball. However, the orthotics dept sent an OA fullforce. I also purchased the OA reaction. Is the OA fullforce OK or should I exchange it for the OA adjuster? And is the OA reaction ok?
    • The OA FullForce is a lighter lower profile brace and would be better for someone playing sports than the Adjuster. The OA Reaction is also ok and can be used. The OA reaction is for mild OA, the FullForce moderate.
  • Martin at 3/14/2016 12:55 PM
    • My daughter had a lot surgery and received a full force from her doctor it is tight around her thigh. The doctor said to use a blow dryer to widen the plastic around her thigh is this correct?
      Also is this brace good for playing sports once released or will that be a different brace?

    • The Full force is made of aluminum not plastic so a hair dryer will not do anything to the frame. The aluminum is moldable though so you should be able to pull the frame apart to make it alittle bigger. This brace can be used for sports as well
  • R. James at 2/23/2016 1:06 PM
    • I had acl surgery about 7 months ago, and am hoping to get back into semi competitive sports: basketball and soccer. What is the difference between this one and the armor brace? Both look almost identical. Also, What is the difference between the short and the standard calf length?
    • The difference is the frame. The frame is a thicker aluminum on the Armor than the Full Force. The difference between the standard calf and the short calf is 1". The standard brace is 16" in length and the short calf is 15"
  • Willie at 2/18/2016 6:50 AM
    • Back in August of last year I had a bad fall and suffered a tibia plateau fracture which required surgery where they pinned and plated it all back together. I also injured the ACL and LCL which also required surgery to repair them. The bone has fully healed but the knee is still very unstable and I'm dealing with a lot of swelling issues. Before the injury I was very active with running, climbing, biking and skiing. I have don joy sleeve brace with the hinge and two straps and am looking for a different brace that will provide a lot more support that will allow me to become more active without the risk of putting more stress on the ligaments. I need a few suggestions on what brace to purchase
    • The Don Joy Defiance is our premier functional knee brace and provides maximum support to the knee during all activities. The brace is custom made for your specific knee to give the best fit. We have a couple of patient ready braces that offer the same support and protection but are no custom made so the fit is based on 3 measurments. The Don Joy Armor with foucepoint hinge is a brace to be worn for contact activities and the FullForce is la lower profile brace

  • David at 2/16/2016 1:35 PM
    • I run long distances. My knee will sometimes start to ache with an interior pain. When skiing my knee tires quickly from the constant bend and straighten cycle and I don't seem to be able to go for more then a day or two of skiing. Should I be looking at the CI brace?
    • Since you do not have a specific injury then yes I would suggest the CI strapping for you on this brace
  • Michelle at 2/16/2016 10:14 AM
    • Why is the Fullforce recommended for meniscus injuries, yet the Armor is not?
    • Any hinged knee brace will be indicated for a meniscus tear, including the Armor
  • Delaney at 2/10/2016 7:49 AM
    • I have recently suffered a knee dislocation and partially tore my MCL and suffer for great instability. I am looking for a brace that will allow me to continue to play during basketball season...would this be a good choice?
    • The Full Force is for ligament instability of the knee. I better choice may be the Tr-Pull Advanced system. The brace is for those who have suffered a patella dislocation. The brace will keep the kneecap tracking in the correct position and help to prevent further dislocation. You can get the brace with hinges which will provide medial and lateral support https://www.betterbraces.com/donjoy-tru-pull-advanced-system-1
  • RP at 2/9/2016 6:12 PM
    • I recently tore my ACL for the second time playing basketball. I still have stability in my knee, and want to bypass a second surgery. I want to continue to run and play basketball competitively. Is the full force ligament brace the right brace for me?
    • Yes the Full Force will provide you with the support you need. The brace 's fourcepoint hinge will protect the knee from further damage
  • Kait at 2/8/2016 7:04 AM
    • Hey there,
      I tore my acl almost 3 years ago. I have not had any surgery. I would like to know what brace would be best for me? I crossfit and would love to get back to playing soccer and basketball. Thank you!
    • The Don Joy Full Force Ligament knee brace would be a good choice as it is going to offer great support to the knee and help to prevent another injury. The brace is light weight and low profile and a good choice to use wheil playing sports. https://www.betterbraces.com/donjoy-fullfource-ligament-knee-brace
  • TW at 1/24/2016 7:16 AM
    • Hi there,

      I had ACL reconstruction in 2005, with 2 scopes prior to removed damaged cartilage. The last several years I have used minimal or no support while playing sports or exercising without issues. Recently, I tired skiing and jarred my knee. My reconstruction is still stable, but I have been considering a brace. I need one that will be best suited for sports such as baseball, hiking, jogging, circuit training and biking. No skiing!

      I am expecting the Fullforce or the Defiance Custom Knee brace, but being a student I am concerned about the price. Can you offer advice on what would be my ideal brace but also ones for individuals on a budget.

      Thank you.

    • The Defiance or the FullForce are you best choices, however a less expensive solution is the Playmaker II with the FP hinge. It is a soft brace and will offer ACL protectin because of the Fourcepoint hinge. this hinge is the same that is on the Full Force and Defiance. If your knee is stable then this brace can help with training your knee to stay out of that "at risk" position and provide ACL support
  • Kim at 1/15/2016 1:40 PM
  • derek at 1/5/2016 11:52 AM
    • Hi, ive been looking through some of the braces and cant quite figure out the best fit. I recently reinjured my mcl/pcl. I also have osgood-schlatters and chondromalacia. i was wondering what brace would alow me to keep playing hockey?
    • The Playmaker II knee brace will protect both of those ligaments and you an get the brace with a patellar donuts to support the kneecap. The brace can be worn while playing hockey
  • Matthew at 1/5/2016 7:40 AM
    • How come in some pictures there is an extra strap across the lower thigh and in other pictures there is not?
    • When you order the brace you will be asked which knee compartment you want. The ACL is the strapping with no anterior thigh strap, and the CI strapping has that anterior thigh strap.
  • Matthew at 12/31/2015 5:48 PM
    • How come it says it's best for football practice instead of saying football in general?
    • The Don Joy Full Force is not considered a brace for contact sports. The brace can be worn by someone who plays a position that will not be getting constantly hit such as QB, WR or DB. But for Contact the Don Joy Armor would be a stronger brace
  • Steve Hall at 12/10/2015 7:58 AM
    • A result of my Primary Lateral Sclerosis is a weak left leg where the knee is hyper-extending (backwards as a bird's leg). I have tried several braces to restrict the backward tendency without success. Will your DonJoy Full Force prevent my knee from going beyond the straight upright?
    • The fourcepoint hinge will create resistance to knee extension and the resistance can be easily adjusted so this may help with your hyper-extension.
  • mark young at 12/9/2015 6:13 AM
    • I'm interested in the Fullforce ligament brace and I'm wondering if you have official coding that would allow me to get insurance reimbursment. Thanks,mark
    • Hello,
      Thank you for your question. The Fullforce recommended HCPC code for reimbursement is L1845. Please contact with questions or concerns at 800-553-6019.

      Have a Great Day
  • Staci Leavitt at 11/26/2015 8:47 AM
    • I had a partial meniscus removal in my knee. Felt great for 2 weeks and then I had severe pain under the knee on inside, almost like bone on bone. (Since then I have had two cortisone shots in two different locations which helped some) I can do any kind of exercising that doesn't require my knee to extend. Walking is super awkward and painful because my knee feels like it is hyper extending all the time. I love to walk but haven't done so comfortably for months now. I was wondering if this brace or any other would help me?
    • Staci
      If your pain is under the kneecap then this brace might not help. You would want something like the Reaction Web Knee brace. https://www.betterbraces.com/donjoy-reaction-knee-brace
      If you have pain on the inside of the knee and hyper-extend the knee, then maybe the OA Full force brace could help. The OA Full force can unload that inside of that knee to help decrease the pain. The outside hinge will telescope in toward the knee to unload the inside of your knee. https://www.betterbraces.com/oa-fullforce-knee-brace
  • Angelo at 10/28/2015 6:12 AM
    • I had ACL surgery over 20 years ago at age 23. I'm now 45 and play tennis 3-4 times per week.

      I saw my doctor about a new knee brace and he had me call his "knee brace" guy.

      However, I was not comfortable with suggestions.

      I don't have any knee problems now. However, I like wearing the brace for protection.

      Can I use a sleeve with hinges or should I buy a more expensive brace?

      Please help. Thanks.
    • Angelo
      A soft hinged brace most likely will not protect your knee from an injury. The only soft brace that I would recommend to you would be the Playmaker II with the Fource Point hinge. The hinge on the brace can train your leg to stay out of the "at risk" position and thus help to protect against a re-tear of your ACL.

  • Julie at 10/23/2015 11:05 PM
    • I have the Full force knee brace. I need to order replacement straps and a liner for my brace. Is there any straps that provide extra padding on the anterior upper thigh strap. Right now I jerry rigged some extra padding as the strap was cutting into my anterior thigh causing blisters and bleeding. I have the undersleeve but sometimes it is just too hot to wear it.
      I have EDS and will be wearing this brace for a long time.
    • Julie
      Liners for the Full Force can be purchased here: https://www.betterbraces.com/fullforce-suede-strap-pad-liner-kit
      These straps will fit your brace: https://www.betterbraces.com/donjoy-female-fource-replacement-strap-kit

      Wearing the undersleeve will help prevent any irritation but if the frame is digging into your thigh you can bend the frame out slightly to make it fit better
  • Maha at 10/20/2015 11:13 AM
    • Hello,

      I tore my ACL and am awaiting surgery. I play indoor soccer and need a brace for support. I can't decide between the playmaker 2 and the full force. Can you let me know which is better along with the significance of the donut hole to and for me?
      I play striker if this helps. I am also doing a lot of quad and hamstring strengthening at the gym. If this could help with that. Can you recommend the short or long one for me as well?

      Appreciate any help you can offer.

      Thank you.
    • You should get the Full Force Ligament knee brace with the short calf. this brace is much more supportive than the Playmaker II and is more appropriate for your situation
  • Gavin at 10/16/2015 9:34 PM
    • I need replacement straps for this brace, particularly the upper thigh (front) strap. I don't see replacement straps for this specific brace on this site. Are the straps the same for this brace as the Armor or Defiance? If not, how can I order replacement straps for this brace?
    • Gavin
      You can order the replacement strap kit for the Full Force directly from DJO by calling 800-336-6569
  • Connor at 10/2/2015 4:04 PM
    • I need to know how long this brace takes to be made and shipped. I need a brace as quick as possible for football season.
    • Connor
      The Full Force is a patient ready brace so if it is in stock it will be shipped as soon as it is ordered
  • Tyler at 8/9/2015 6:57 PM
    • Tore my PCL and ACL. Looking at either the Armor or Fullforce knee brace so I can play hockey and baseball without any pain. What is the difference between the short and long brace? My measurements put me right in the middle of medium and large. Measurements are 14 calf, 15 knee, 22 thigh. Should I be on the safe side and go with large or the medium with a snug fit
    • Tyler
      There is no functional differencs between the long and short calf. If you need to wear shin guards r boots for skiing then you would want the short calf. The difference betwenn the two braces is that the Armor is considered for contact sports and has a thicher frame than the Full Force. You may want to go with the large to make sure the thigh is comforatable in the brace
  • Cyndia at 6/24/2015 5:41 PM
    • I am a 57 year old female, 5'8, 160lbs. I fully tore my ACL and am considering surgery once I have full range back. I would like a brace that will allow me to swim, square-dance, and hike (nothing super aggressive) for pre-op and post. Which would be a better choice - the Female Fource or the Full Fource and why?
      Thank you.
    • While both braces offer the same support and are made with the same aluminum frame, the FullForce would be better in my opinion. The FullForce has the newly designed fourcepoint hinge and is lower profile to not as bulky at the hinges.
  • Erika at 6/16/2015 6:51 PM
    • What is the difference between the FullForce OA and the FullForce Ligament brace? Does the Ligament brace still offer the same "off-loading" as the OA brace?
    • The Difference between the DonJoy FullForce Ligament Knee Brace and the DonJoy OA FullForce Ligament Knee Brace is that the DonJoy OA FullForce Ligament Knee Brace is specifically designed to be used for individuals with single compartment osteoarthritis of the knee. It has an offloading technology to offload the OA affected compartment of the knee. The DonJoy FullForce Ligament Knee Brace is specifically used for ligament instability and protection. It does not offer any off loading.
  • Jag at 6/1/2015 10:16 AM
    • Hi Support

      I had a PCL, PLC & LCL reconstructive surgery(using allograft -from donar) 3 months ago, i feel like my knee is not stable , its giving away side ways ( moves site to side) whenever i walk. Would appreciate if you could advice me on which brace should i go for ?, im a soccer player and do alot of running and jogging.

      I also need you to recommend me a brace to use for normal day to day activities - going to work, walking around malls etc etc..

      Planning to get 2 brace -- 1 for sports activities and 1 for daily use.

      hope to hear from you

    • Jag
      If you have a PCL injury then i would suggest the Don Joy Armor with the Standard Hinge. The brace will support all of the ligaments that you have injured and is a great brace for both sports and daily living. There is no need to get a second brace. If you want something a little lighter for daily activities then i would suggest the Playmaker II knee brace. https://www.betterbraces.com/donjoy-armor-knee-brace-with-standard-hinge https://www.betterbraces.com/donjoy-playmaker-ii-knee-brace
  • Jay at 5/28/2015 11:20 PM
    • Hi,

      I'm a soccer goalkeeper and am constantly diving, bending and twisting to make tough saves when playing competitive indoor soccer. I generally don't have a lot of contact with other players but I'm always saying hi to the ground/floor. Lol. I was wondering if this would be the brace for me?

    • Jay
      I would suggest the Don Joy Armor Knee Brace with fourcepoint hinge instead. The Armor has a stronger frame and will withstand the contact with the ground better. https://www.betterbraces.com/donjoy-armor-knee-brace-with-fourcepoint-hinge
  • Jason at 5/20/2015 7:29 AM
    • Torn ACL Meniscus and MCL. Im back to running with no pain. Im ordering a FULL FORCE at the request of my PT. I want to play basketball. Should i get ACL or CI and should I get standard or short length?
    • Based on your injury I would suggest the ACL DonJoy Full Force. The ACL strapping will protect both the ACL and MCL ligaments. In regards to selecting short or standard length on the calf portion, this depends on if you will be using the brace with a tall boot, like with skiing or motocross, or if you are under 5'3 tall. If so, you would select the short calf style. The calf frame is 1in shorter on this style. It will not take away from the support of the brace.
  • Nate at 5/6/2015 5:54 PM
    • Hello, I had a complete ACL tear from recreational soccer 2 weeks ago....am currently doing PT, with full ROM returned and am walking without a brace. Am waiting to do surgery until after our family vacation in 3 weeks where we will go scuba diving. Looking for a brace I can wear during diving...I have a brace that was fitted from my ortho but it is over $1000 and they say I can not get it wet. What would be best that I can get wet.
    • Nate
      The Full Force Ligament brace will provide great protection of theyour knee and it can get wet. The brace has our fourcepoint hinge which is designed specifically for the ACL and the brace is light weight and low profile
  • Kevin at 4/27/2015 1:34 PM
    • I was giving this after I had ACL surgery from my orthopedic doctor. Its been a couple years of use and the inner pads where the joint is have come off. Is there anything I can do or can I purchase new ones?
    • Kevin
      If you just need to pads themselves they are available here: https://www.betterbraces.com/donjoy-replacement-parts
      If you need the velcro that holds the pads onto the brace then you will need to order that from DJO direct by calling 800-336-6569
  • Paul at 2/7/2015 4:04 PM
    • Hello. I was wondering what the overall length of the Full Force in a SHORT, medium size, CI version, right leg. Im 5'4". And what would be the best option to keep it from sliding down my leg while running AND make it more comfortable because i have to wear it all day at work also. I'm also considering the ACL Everyday Brace because of its overall length...
    • Paul
      The Full force in a short calf is 15 inches in length and based on your height this would be the best length for you. The Full Force is the better of the two braces and can be worn for running as well as everyday activities. The ACL Everyday is a shorter brace about 12 inches but is not for someone who is active.
  • Nick at 2/1/2015 12:34 PM
    • I had LCL & ACL surgery and I plan to return to Wrestling and Judo, but not full competition, I just like to train. How would this brace hold up to these types of combative sport? or what brace would you recommend instead?

      The Full force would be a great choice. The brace is light weight and low profile while providing protection of the knee. I would suggest a brace cover as well https://www.betterbraces.com/donjoy-sports-brace-cover

    • Can my Defiance be retrofitted to change it to the Fource Point Hinges?
    • Joy
      We can do that it is called a retrofit
  • Joy at 8/19/2014 7:55 PM
    • I already have a DonJoy Defiance brace and have a couple of issues and questions.
      What is the weight difference between Defiance II and the FullForce?
      What parts should I buy to help prevent it slipping down? I already have the neoprene sleeve but live in a hot, humid climate and can't wear it in the summer.
      I have Multiple Sclerosis and hyper extension of my knee with every step. My ortho adjusted the hinges to prevent full extension but because it is basically 'free-wheeling' (good for most people, bad for me) there is still a bad snap back. Even though it stops before full extension, there is no tension to slow the painful snapping action. Is there any other adjustment he can make to add tension or slow the hinges just prior to hitting the stop? Due to the MS I have shortened calf and weak, unresponsive hamstring muscles and almost no control of the extension while standing or walking.
      I also have an AFO but cannot wear it with Defiance because the AFO comes too far up my calf. I have to make the choice of foot drop or no knee control. If I order FullForce I should get the short, right? It is shorter from the knee down and I may be able to wear it with the AFO? If it simply does not work can I return for a refund?
      Thank you very much.
    • Joy
      The Defiance weighs 22oz and the FullForce weighs 20 oz. If your Defiance has a Fourcepoint hinge that can be adjusted to apply 6 lbs of pressure to resist extension, that is the only other suggestion I can make if you already have stops in the brace. The only difference between the FullForce and the Defiance is the 3 oz weight, and if you do not have a fourcepoint hinge. If you do not know if you have that or not you can give us a call at 888-405-3251. In order to wear the AFO and the Brace you would need to take a measurement of your calf with the AFO on and use that for your calf measurment. We have a neoprene suspension strap that can be used for brace migration.https://www.betterbraces.com/donjoy-neoprene-suspension-strap-kit If you purchase a brace on BetterBraces we give you a 90 day moneyback guarentee

    • Hi, I had an ACL surgery 8 months ago, and I still have some pain in my knee I think it is because I need more strength on my quadriceps, but when I work out the pain comes. I used to practice kitesurfing and some running, do you recommend the fullforce knee brace?
      I’m 5’4” tall and the measures of my injured knee are: Thigh 17,7” Knee 14,2” and Calf 13,4”.
      I hope this measures increase while a get my leg stronger since my good knee measures are: Thigh 19,3” Knee 14,2” and Calf 13,8”.
      Which size should I buy Small or Medium? I will buy also the neoprene sleeve.
      PD: if I get the short one, should I still measure 6” above and bellow the knee?
      thanks in advance
    • David
      Based on your measurments and considering that you will most likely build up more muscle in your thigh I would say go with the medium brace. The frame is moldable so you can make it tighter on the thigh and the calf, then when you feel it is getting tighter you can pull the frame out a little to make it bigger. The short version is still measured at 6" below the mid kneecap.
  • Mike at 6/3/2014 12:44 AM
    • I've read that the DonJoy Full force brace is lighter than the Action Armor Extreme brace, but would like to know what exactly is the weight difference between the two? I'm 5'8" and weigh about 195 lbs. so am thinking that the weight difference would not make that much of a difference for me because of the muscle mass that I carry. I would like to use the brace for playing basketball, running 5Ks to marathons, swimming and biking (Xterra races). I have a partial meniscus tear and ACL Patella autograft revision (2nd ACL reconstruct) on my left knee and also a Patella ACL reconstruct on my right knee. The left knee was done in 1989 with a hamstring autograft and recently redone 3 weeks ago, and the right knee was done in 1998. Thank you!
    • Thank you for your question. the weight difference would be about 1 ounce. This it not a significant amount, however when running long distances or using it for an extended period of time, one may notice the weight difference. the Armor is a thicker brace and generally suggest for contact/extreme sports.
  • John at 5/30/2014 9:21 PM
    • Hello,

      My FullForce knee brace shipped with a packet of metal pieces labeled 45, 60, 75, and 90, and two small screws. The packet itself was labeled with the number "12-2352-0-00000." What is this hardware used for?

      Thank you.
    • John
      That is the flexion/extension stop kit. That would only need to be used if your physician wanted you to have limited range of motion. The pieces go into the hinge to limit movement of the knee
  • David at 4/7/2014 7:51 PM
    • My son had a partial tear of his ACL about a year ago. He ha since started traveling soccer, and keeps tweaking his knee. He needs a brace for support and we are looking at the full force ligament brace. He is only 12 so we would like to get a brace with room for growth. He measures thigh- 17" ,Knee14 3/4 ", and calf 14" what size would you recommend ??

    • Thank you for your question. Although your son's measurements for his knee and calf fit in the low range of the Medium measurements, his thigh is well within the small range. It would be suggested to go with the small, which will accommodate his knee and calf, and would allow room for thigh girt development.
  • Joe at 4/5/2014 8:45 AM
    • I am awaiting surgery to repair a ruptured ACL and a medial meniscus tear. In the mean time I am looking for a brace to wear for pre-op protection and stability that I can also use for protection & stability to return to non-contact/minimal-contact recreational sports (triathlon, lacrosse, & maybe hockey) after my recovery. I'm 40 yrs old, 6'0, 165lbs. I'm leaning towards the Full Force w/ Fourcepoint hinge, but have 3 questions.

      1. I see that the Amor brace now comes with a low-profile Fourcepont hinge. Does the Full Force also offer the low-profile Fource Point hinge?

      2. Is there any reason not to get the CI version with the extra strap, even though my injury was strictly with the ACL? Would the CI version provide extra protection and stability? Is it easy to add/remove the extra thigh strap to convert the brace back and forth between CI and ACL only?

      3. I understand that the Armor is stronger and heavier, having two layers of aluminum rather than just one, but can you tell me exactly what the weight is for the Full Force and for the Armor? I understand that it would depend on the size, but I'm just looking for some numbers for comparison sake. For what it's worth, I'd be buying a medium. I'm trying to get an idea of how much weight I'll be adding to my leg as compared to the neoprene brace that I have now.

      Thank you very much!!!

    • Joe
      1. The FullForce has the same low-profile fourcepoint hinge as the Armor
      2. Get the ACL stapping you do not need the CI strapping
      3. The Armor is 23 oz and the Full force is 20 oz
  • Marcos at 3/29/2014 9:34 AM
    • Another question: is possible to run and go to the gym with the fullforce brace? Thank you once again
    • Yes you can do any physical activity in the Full Force
  • Marcos at 3/29/2014 9:27 AM
    • Wich flexion is achieved with the fullforce? Is there any difference to armor.? Thank you
    • The difference between the full force and the armor is the thickness of the aluminum fram only. The Armor is thicker and would be a better brace for full contact sports or skiing. The Full Force is lighter wieght and is better for speed
  • Gail at 1/12/2014 4:08 PM
    • How much does the brace weight?
    • 20 oz
  • David mazariegos at 1/11/2014 12:23 AM
    • I just had an acl surgery, looking to get back to basketball soon. What is the best knee brace for a big fella?
    • David
      The full Force is a good brace post surgery to get back into sports. Make sure you follow the sizing chart and if you do not fit into one of the sizes you may need to custom
  • Tommy at 12/30/2013 6:06 PM
    • I had ACL recon almost 8 mo ago. I recieved my Fullforce knee brace, and trying to fit and set the settings. I have flexion and ROM, and will be using it while playing baseball and hiking. About the settings, do the resistance adjustment screws control extension or flexion? Also, does the resistance switch control extension? I see that standard ext stops are at 10* but does turning the switch to "off" turn the ext stop off, giving full extension? At 10* i still feel like i need to extend fully to walk, run, and stand. Thanks.
    • Tommy,
      Thank you for your question. The flexion and extension stops need to be changed out though your Physical Therapy clinic or through a DonJoy rep. You can find your rep by entering your zip code into the following link.
      The FourcePoint Hinge offers resistance in the last 35 degrees of extension (that's with the 10 degree stop in, if changed to no extension stop it will begin to offer resistance at 25 degrees). You can change the resistance setting from 1,2 or 3, which offers 2,4, or 6 pounds of resistance during that last 35 degrees of extension. This will cause a deceleration giving protection to your ACL. You can also set the resistance to 0 (offering 1 lb of resistance) or turn it off simulating a standard hinge with no resistance.
      Please let us know if you have any further questions.
  • Kala at 10/5/2013 5:20 PM
    • I am a level 8/9 gymnast and headed of to college next year and I have a question I fell and hit the inside of my knee. Since I was able to walk the doctor just did a x-ray and said all was fine I wear compression knee sleeves to combat swelling. I was wondering does DonJoy have a brace that would support my knee from feeling like it is giving out when leaping and tumbling. I have also noticed most companies really focus on football and basketball. Most braces I have had over the years hardly last 3 to 6 months. I would love to get a bunch of gymnasts together and help a company make braces that work for gymnastics. The foam pit really messes up velcro, and when it gets messed up we either stop wearing the brace, tape it, or try to replace it which isn't always an option with the price of gymnastics.
    • Kala
      Thank you for contacting product support. Take a look at our Reaction Knee Brace: https://www.betterbraces.com/donjoy-reaction-knee-brace The Reaction reduces anterior knee pain by dispearsing force across the knee. It has a web design that stabilizes the patella on all sides and absorbs shock and shifts peak loads away from the painful area of the knee. Its comfortable to wear and it's breathable. This might work better than a traditional neoprene sleeve for the stuff that you will be doing. If you have any other questions please do not hesitate to ask.
  • Gus at 6/13/2013 6:24 PM
    • Could this brace help prevent lateral knee dislocations. I'm a lineman and I've dislocated my knee 7 times in the past two years, and I'm worried i might tear something next time it happens
    • Hello Gus,

      Do you mean Knee Cap Dislocation? We have Patella Braces, to support the knee cap and provide proper alignment. The FullForce is an ACL Brace, and supports the MCL, and LCL. It supports the Ligaments of the Knee.

      The Fullforce is a great, light brace for football players who need knee support. But if you need a patella brace this is what I recommend.

    • I just hd my ACL reconstruction surgery 3 weeks ago,im considering to buy Donjoy Fullforce or Armor knee brace...which one is suitable for me ??
      Im a Basketball player
    • Hello Khiew,

      If your unable to order a Custom ACL brace, and are interested in purchasing an Off the Shelf Brace, I recommend a Fullforce for basketball players, it's a lightweight brace, comes with fourcepoint hinge which protects the ACL, and has a swooping thigh cuff to accomodate your thigh.

      The Armour is best suited for football or contact sports. Its the strongest frame on the market.

      Please Call Us at 1-888-405-3251 so that we may assist you with placing your order.

      Have a Great Day.
  • David at 1/8/2013 12:43 PM
    • This question was asked previously and it has to do with the pads pinching the knee and causing pain after a while. It was suggested to use the thinner pads, done. However, still some pain after about 2 hrs of use.

      I had originally gotten this before my surgery and it was fine, now that i have started PT and working again i have noticed this.

      I was told by the rep when i first got this, that the folds in the framework were made to be bent and adjusted to help with fitting. Whats the best way to bend it without breaking something?
    • David,
      If you are having some tightness at the knee joint, grab the brace at the condyle pads on the hinge and try and seperate the sides some, try it back on and see if that has alleviated the problem. Continue until you get a slight seperation that doesnt have a pinching feel, but you dont want to get it too wide that it starts to feel "sloppy" in the knee area.
  • Lyndsey at 6/21/2012 8:16 PM
    • I had two questions regarding this brace.
      1. For MCL injury should I order the ACL or CI option?
      2. Reading above questions I noticed short people or people with calf muscles that sit high should order the shorter length. I am 5'4 female with a high, good sized calf muscle and I was wondering if it is recommend still that I order the short length or not? I want the best fit possible without too much compromise of support.
    • 1. ACL Strapping
      2. Short Calf
  • Chris at 6/14/2012 7:31 AM
    • I am involved in contact martial art sports such as Brazilian JuJitsu and MMA. Is there any pad or sleeve that can go over these braces to protect my training partners from the metail hinges and rings?

    • You need the Donjoy Sports Cover.

  • jon at 5/16/2012 1:10 PM
    • I have a tear in the miniscus and a repaired torn acl previously, my question is i would like to continue playing basketball and softball but i want to be protected. Is the don joy full force the best option for me because i like the fact that it is light weight so i can still move fast but i want to make sure it is supportive of my injury?
    • Yes the Donjoy FullFource would be the best option with your condition and activity level.
  • Max at 1/25/2012 6:24 PM
    • Would this brace work for an MCL injury. If not is there a brace that would work for an MCL?
    • Yes the FullFource does support the MCL.
  • Tyler Beach at 12/20/2011 8:01 AM
    • How do I wash the Donjoy Full Force brace?
    • You can wash all the softgoods by hand with laundry detergent, rinse, and air dry. Re-lubricate the hinges using a dry, Teflon based lubricant. Bicycle chain lubricant usually works well.
  • Tracey kingsley at 11/6/2011 1:17 AM
    • Hi

      I am looking to purchase a donjon knee brace open hinged for skiing. I had an ACL reconstruction 20 months ago.

      1. Is the clearance Amor Fource point ACL knee brace suitable for skiing an tennis?

      2. Does it come in short length for skiing?

      3. Could I wear my thermal legging under the brace for comfort.

      4. Is their a female version?

      Please tell me which brace will be most suitable and comfortable for skiing with best propection that is lightweight with full protection after ACL reconstruction surgery.

      I look forward to hearing your recommendations



    • Hi Tracey,

      Either the Armor or FullForce braces will provide support for your ACL while skiing. The Armor and FullForce are the same brace, except the Armor is re-inforced making it the strongest off the shelf brace we carry. The Fullforce is the lighter of the two. Both braces have an option for a short calf length, which you will need to fit into ski boots and can be worn over a thin base layer. The female version of the FullForce comes standard with a short calf, but there is no difference in the frame to make it more female specific. Bottom line is either brace will privide solid protection, the Armor is stonger, the FullForce is lighter weight and slightly lower profile.

      If you have additional questions please call, 1-800-553-6019

      Have a great day.
  • Brandon at 7/7/2011 5:12 PM
    • I am looking in to getting a new knee brace because the one I have no longer fits me properly. I am liking the full force knee brace, but I have a couple questions. First question, what is the difference between the short and standard length? The brace i have now is just under 15 inches, so i was wondering which length I should get? Also, I have been looking at the new Armour brace and was wondering how much of a weight different there is between the Armour and the Full Force?
    • The Donjoy Full Fource standard length is 16" the short is 15" so you should get the short. The Armor Knee brace is heavier than the Full Fource because it's made of a dense thick aluminum. Should you have any other questions please let us know.
  • Dave at 6/10/2011 3:42 PM
    • How do I tell if I have a short or standard calf lenght?
    • A standard length brace is 16" in total length, from the thigh bar to the calf bar.
  • Ronald at 4/14/2011 5:09 PM
    • I'm trying to decide between the DonJoy Full Force and the DonJoy Armor Knee Brace with FourcePoint Hinge. How does the hinge f\technology compare between these two braces?
    • The FullFource and the Armor with Fourcepoint Hinges have the same hinges. The Armor frame is a denser thicker aluminum frame recommended for contact sport athletes. Should you have any additional questions please call us at 800-553-6019.
  • Jim at 3/4/2011 10:13 AM
    • Hi! I had ACL reconstrucive surgery a few months ago. I'm ready to go back to playing hockey and my ortho recommended wearing a knee brace. Would the standard or short calf model be best for me? Or does it even make a difference?
    • Hi Jim,
      Most Hockey players will wear a knee ligament brace with a short calf length to avoid pinching between the calf frame and top of the skate. So for comfort reasons I would suggest a short calf frame.

  • Dean Guiuan at 3/3/2011 6:40 PM
    • Two Questions;

      1.) What is the difference between short and standard options?

      2.) I know the ACL option, what does the CI option mean?

      Thank you,
      Dean Guiuan

    • 1. The difference between short and standard is the length of the thigh cuff. The standard is one inch longer than the short.

      2. CI stands for Combined Instability. This is the option you would pick if you had an injury to both your ACL and PCL. It gives you an extra thigh strap in the front.
  • Frank at 12/5/2010 4:51 PM
    • What would be the best and lightest brace possible at the Middle Linebacker position for football? The one that I have now by townsend is too heavy and is constantly sliding down.
    • Hello Frank,

      The DonJoy FullForce will provide the most support at the lighter weight than the Armor or other similarly constructed braces.

      The brace itself is malleable, meaning it can be bent without breaking. If you find that either cuff is loose and the straps aren't tight enough, simply bend the cuff to match the shape for a more snug fit.

      You may also want to try an undersleeve or Silicon Strap Padding to address migration.
  • Kyle at 12/2/2010 8:33 AM
    • Is the Full Force made of carbon fiber or aluminum? The description says aluminum but the picture looks like carbon fiber.

    • The DonJoy Full Force Ligament Knee Brace is made out of aluminum. The Carbon fiber appearance is cosmetic. It's actually the same material the DonJoy Armor is made of.
  • Ray at 11/4/2010 11:44 AM
    • I recently had acl surgery about three months ago, I getting a knee to start my running program and for when go back to playing football. I play d-line so they recommended the amor brace but i feel like the fullforce would be better for my style of play and for other sports activites I do. Like Muay Thai. I just need a suggestion on which would be better.

    • Hello Ray,

      The DonJoy Full Force Ligament Knee Brace is a great alternative to the DonJoy Armor. The Full Force is constructed of the same material as the Armor, but at a lighter weight. Ideal for quick moving activities where the impact protection offered by the Armor is not required.
  • Karen at 10/28/2010 8:55 AM
    • I use a Full Force ACL brace and really like it. Can I swim with it on? if so, how do I care for it after it's wet?
    • Yes you can swim with it. After use, rinse with fresh water and air dry. Do not put any of the softgoods in the dryer.
  • Richie G at 9/4/2010 5:29 PM
    • Will the full force rust in salt water? I have a armor and the "d" rings rusted out
    • Hello Richie,

      The DonJoy Armor Knee Brace has metal tabs and "D" Rings, but the DonJoy Full Force Ligament Knee Brace has plastic tabs and metal "D" rings. The rust should be less of an issue, but you want to be sure to rinse the brace in freshwater after immersion in salt water.
  • nate at 8/14/2010 3:08 PM
    • i play football i am the running back i need a brace for both knees i have ripped my mcl on one knee and ripped my meniscus and acl on the other i need protection for both knees for everything whats the best knee brace for me?
    • The DonJoy Full Force is a great choice. Your other two options would be the DonJoy Armor which is stronger and slightly heavier brace that offers a bit more protection. If you want and can afford to go custom you would want to get the DonJoy Defiance knee brace. It's the lightest, strongest and best fitting option. It's the same ACL knee brace you see all the NCAA and NFL players such as Peyton Manning and Phillip Rivers using.
  • Bill at 8/4/2010 9:33 AM
    • Hi. I am interested in getting a knee brace for soccer but I am wondering what would be best, the donjoy armor or the donjoy fullforce?
    • Hello Bill,

      The DonJoy Full Force Ligament Knee Brace is most commonly worn by competitive athletes that can't afford to be weighed down by a heavy brace, and are not trying to prevent contact or impact related injuries (like a football lineman might want to do).

      The FULLFORCE knee brace is sleek, low-profile, and exceptionally light weight. It is ideal for mobile athletes like wide receivers or soccer players that are looking for complete protection for their knee, but don't want to sacrifice speed.

      The DonJoy Armor is a studier, heavier brace designed to take more impact. Given your sport, I'd definitely go with a DonJoy Full Force Ligament Knee Brace.
  • Locke at 5/5/2010 10:42 AM
    • Hi, I’m interested in the DonJoy Full Force Ligament Knee Brace. My question is what’s the difference between the CI or ACL option.
    • The difference between the CI and the ACL option for the DonJoy Full Force Ligament Knee Brace is the strapping sequence. The ACL option has 5 straps; 2 posterior thigh, 2 anterior calf, 1 lower posterior calf. The CI option has all 5 straps the ACL option has plus 1 extra strap on the anterior thigh.
