Product Description

Is the OA FullForce Brace right for me?

Ideal for active individuals recovering from a ligament strain. Try our Brace Advisor for personalized product recommendations to meet your needs!

More Miles, Less Pain

The DonJoy OA FullForce off-loads the affected compartment of the knee while reducing ligament strain.

  • 3-Point Off-Loading mechanically shifts the painful joint loads from the degenerative compartment to the healthy compartment, while the hinge allows the ability to fine-tune the load.
  • 4-Points-of-Leverage is clinically shown to reduce ACL strain by keeping the knee in a stable position to minimize further cartilage damage.

What is Osteoarthritis (OA)?

Arthritis refers to more than 100 diseases that affect the joints and their surrounding tissues. Osteoarthritis, or OA, is the most common form of arthritis. The statistics on OA are staggering:

  • Nearly 21 million people in the United States have OA*
  • The incidence of OA is expected to increase even more as the U.S. population ages*
  • Over 7 million Americans are limited in their ability to participate in their main daily activities because of their arthritis*

The joint most often affected by osteoarthritis is the knee. Knee OA is caused by the degeneration or breakdown of articular cartilage that covers the ends of the bones that meet at the joint. Cartilage serves as a cushion between the bones, providing a smooth surface for the bones to move against each other. When the cartilage deteriorates the bones may actually be rubbing together. Your physician will often refer to this as "bone-on-bone" osteoarthritis.

*Arthritis Foundation

What is Osteoarthritis (OA) knee bracing and how does it work?

Knee braces are available that are specifically designed to treat OA. They stabilize the joint, help reduce pain and help to build stronger muscles, which allows patients to return to the activities they love. Load redistribution and joint alignment Through a process called "off-loading" or shifting, OA braces helps relieve pain by redistributing the weight bearing load on the painful or affected compartment of the joint to the healthy or unaffected compartment.

What to expect from a Osteoarthritis (OA) knee brace

  • Braces cannot cure OA and may not be right for everyone. However, it is a viable solution for many people. The ideal candidates are typically active people who are motivated to strengthen their muscles and willing to wear a brace to realize the benefits of this form of treatment.
  • Discuss treatment goals with your doctor and others on your health care team before you get a brace.
  • Don't expect a brace to feel good from the start. It may take from a week to a month to get used to how the brace feels on your leg. Be patient. It took a long time for your knee OA to develop.

    • Hello I have this brace, when I run or walk alot with it the straps leave a rash, is there a knee sleeve i could wear under this brace to reduce irritation? I am returning to soccer after acl repair and patela graft, so I will be using it alot..
    • We do have undersleeves that work for all of our rigid braces. The cotton lycra undersleeve will provide a nice barrier for when you're wearing the brace, but also be light and breathable for playing soccer. https://www.betterbraces.com/knee-brace-undersleeve-cotton-lycra
  • McKenna at 8/9/2016 6:28 AM
    • I have this brace and I love it and it gets a ton of use. But, the pads on each side of my knee fell off when on the move and have been misplaced is there anyway I can get a replacement for those?
    • Yes, we have the replacement Condyle Pad Kit, you can order here: https://www.betterbraces.com/donjoy-condyle-pad-kit
  • Chris at 7/28/2016 2:40 PM
    • My measurements are 20.5 thigh, 17 knee and 15.5 calf. the calf and thigh are within the medium range, but the knee is in the large range. Which size will work?

    • Based of the measurement we would go with the medium as the swelling might go down on the knee.
  • Jodi at 7/6/2016 3:34 AM
    • I am an 18 1/2 on the thigh, a little short of 14 on the knee center, and a 13 1/2 on the calf. Could you kindly recommend which size would be better suited for me between a small and a medium? Thank you!
    • A size small will be the most appropriate for you to order the DonJoy OA FullForce. Each of your three measurements fall within the small size.
  • Mark at 4/7/2016 10:02 AM
    • Can this brace be wore outside pants? Also my knee is full of arthritis.
    • The brace can be worn on the outside of pants, however you may have issues with the brace sliding. It will fit better and function better directly against the skin.
  • Julie at 3/9/2016 4:32 AM
    • I think I have OA, but I'm not sure if it's medial or lateral. Which brace is right for me?
    • Well if you do not know which side , use the area where pain is located to guide you. If the inside of your knee hurts then get the medial brace if the outside hurts then get the lateral brace. The upright will go on the opposite side fof the pain.
  • Bill savio at 3/2/2016 6:37 AM
    • I have Cigna and ghi insurance and like to know if it might be covered
    • We do not accept insurance as payment through the website. To have your insurance cover the brace please follow this link to find your local Don Joy sales rep. They can bill your insurance company for the brace and give you information on coverage.

    • Hi, I'm 37 years old and had a medial meniscectomy 2 years ago. I play beach volleyball 2 times a week. I have been using the Donjoy Playmaker II for over a year now , but lately I have been experiencing some medial pain in my knee after playing and was looking for better medial offloading support. Which brace would be best for me? Thanks.
    • The OA Nano is a good light wieight OA brace that is worn by active folks. The brace can offload the medial side of the joint to decrease some of that pain.
  • Brad at 12/16/2015 4:39 PM
    • I have a DonJoy OA FullForce knee brace unloading my medial meniscus. I notice a clicking (actually 2, but the first click is the hyperextension lock. This click can be felt and heard (rather quiet). The unknown click happens during flexion. It's the right side hinge. Is this just the hyperextension lock "locking then unlocking" or something wrong?
    • The clicking could just be the extension stop getting hit when the brace bends and extends. If the hinge catches when bending or extension then you will need to return the brace

    • I do a lot of surfing and need a brace that is waterproof. Which braces are waterproof? Thanks!
    • John
      All of our rigid knee braces can be worn in the water. If in the ocean we just suggest that you rinse the hinge with fresh water afterwards to remove any sand
  • Diane at 3/9/2015 2:23 PM
    • Hi,

      I have multiple sclerosis that has affected the muscles in my right leg to the point where I cannot prevent my right leg/knee from "locking/hyperextending" with every step. In addition, my leg "caves inward" from the knee whenever I bend it, such as sitting down or doing a squat. In other words, whenever I try to squat down my right knee "travels" significantly to the left. Because of this combination, I now have a constant ache on the inside of my right knee that sometimes radiates to the front of it.

      My orthopedic has proscribed a range of motion T-scope brace. Do any of the OA braces have ROM locks to prevent the leg from completely straightening (i.e. locking/hyperextending)? What would be your recommendation for the lightest weight brace that could potentially bee worn on the outside of slacks/jeans?

      Thank you,
    • Diane
      Our OA braces can limit extension by adding an extension stop to the hinge of the brace. Most of the braces come with a 10 degree extension stop to limit hyperextension, but a 20 or 30 degree can be substituted. Also our braces are meant to be worn against the skin not on the outside of pants. The OA Full Fource is 20 ounces and low profile also the OA Nano is only 14 oz.
  • Jamie at 7/16/2014 5:49 PM
    • Looking for a brace for my wife who has had 2 medial meniscal surgeries on her left knee in 2 years. Now she has cartilage damage and bone on bone contact in the same knee on the medial femoral condyle. Which brace would be better for her? I was thinking about getting her the OA Full Force brace. Would that be a good one for her and do I get the medial off-loading option? She is quite active at the gym.
    • Jamie
      The DonJoy OA Full Force Knee Brace would be my reccommendation for her. and yes the medial compartment unloading
  • Mary at 7/13/2014 9:43 AM
    • I have lateral compartment degeneration on both knees. I need to get two braces right and left. My question is the OA Fullforce low profile enough that the braces will not catch between the knees? I want to get back to being able to ride a bicycle and know that I can come to a stop and be stable on my legs. I can not do that right now.
    • Mary
      The DonJoy OA FullForce knee brace comes standard with a swooping thigh, which meas that you can wear abrace on both legs without the braces hitting each other.
  • John M at 4/19/2014 7:28 PM
    • I have bone on bone contact on my right knee for many years, my cartilage was removed in a surgery years ago when that was the norm. I have quite severe OA but remain very active all these years. Which OA Full force should I order since I have no cartilage medial or lateral?
    • John
      Since you have bone-on-bone on both sides and the brace only unloads one side you can either decide which is worse the medial or lateral and get the brace for that side. The other option is to just get a ligament brace that will provide stability and support but doesn't unload any compartment. If that is the case I would go with a brace like the DonJoy 4titude Knee Brace
  • Linda W at 4/5/2014 7:11 AM
    • I got the DonJoy OA FullForce Knee Brace from my Orthopedic doctor. Fits good have some issues with it slipping unless I tighten the straps very tight which does cause some numbness. Question is: the inside material is making my leg very itchy. Are there some kind of pads that I can use for the 3 points that the brace lay against my skin? Don't want a full leg cover. Thanks.
    • The DonJoy OA Full Force has suede strap pads and liners, the only way to get something different is to go back to your doctors offic and see if the can get you different strap pads. We do have a sili grip pad that has silicone on the part that goes against you leg. You could also get a chamis anti-migration band that goes under the 4-5 strap. but the best way is to get the lycra undersleeve
  • cindi at 3/23/2014 3:55 PM
    • I have osteoarthritis diagnosed after MRI. my ligaments are in good shape. I've been doing most of the exercises listed here since I first started w the pain late last year. I had fluid drained late November followed by a cortisone shot and another cortisone shot in December w minimal relief. I am on anti inflammatory meds (Tylenol Arthritis, ibuprofen and turmeric) and take a glucosamine/chondritin/MSM supplement and fish oil. The pain is localized to my inner knee. From reading the info here and the comments, I'm already doing a lot of it. I am also working on losing weight which I know will help.

      Can you suggest a a good knee brace that will allow me to continue umpiring fast pitch softball which requires squatting and squats to running? I do not want to give it up and my "teams" don't want me to either. Also, do you work with insurance?
    • Condi
      The DonJoy FullForce OA brace would be a good choice for you. You would want to get the medial compartment unloader for your knee and it will allow you to still do your umping. To get your insurance to cover this you will need a prescription from your physician and will need to go through either our insurnace department at 800-548-3370 or contact your local DJO sales rep by going to djoglobal.com and looking up a rep http://www.djoglobal.com/contact-us/sales-rep-locator
  • taggart at 1/12/2014 7:33 PM
    • I am 8 months post-op from acl reconstruction surgery. I am very active and do sports such as football, soccer, tumbling, wakeboarding, and skiing. I am wondering if the FullForce can hold up and protect the acl for all these sports? I am also looking at the Armor. How well will the Armor do? And which is better for the sports listed above?
    • The Armor would be a better option for Football and sking
  • ali at 10/30/2013 10:19 AM
    • I have bought the lateral right knee brace
      OA full force

      how it is diffeent from left or medial
      I mean by looking at brace
    • Ali,
      The adjustable hinge will be on the unaffected side. Yours is a lateral off loader, so the offloading hinge is on the medial side.

      As far as right and left are concerned you can tell by looking at the lower portion of the frame. Look at the arms that extend down from the hinges, you will notice one side is curved in and the other is straight down. The side that is curved goes on the inside of the leg. If you are looking straight on at your brace you will notice the curved portion on the right side below the hinge.

      Thank you for contacting DonJoy please let us know if you have any further questions.
  • Debra Martin at 10/19/2013 6:52 AM
    • I am a disabled vet who received a Full Force brace for both legs. How can I tell the left from the right in a quick manner?
    • Debra
      Each brace has a swoop or curved edge in the thigh area. The swoop is on the inside of the brace, so when you put the brace on the swoop should be on the inside of your leg, if it is facing the outside of your leg you are putting it on the wrong leg. They should also have the size marked on each if you pull the inside liner from the top of the frame.
  • George Alexander at 10/9/2013 1:11 PM
    • I bought the Don Joy Fullforce three weeks ago. I am not sure its the right size. I used the chart and checked it twice. I bought ght size it noted. But the positionjof the pads on the sides seems a bit lower, more towards the lower part of the knee (towards the foot) rather than centered. Is this correct? Or do I possibly need one size larger?

    • George
      Thank you for contacting product support. It is possible that you are not putting the brace on correctly. The middle of the condyle pads should line up with the top of your kneecap. If you followed the sizing instructions on the BetterBraces website and measured six inches above and below the knee cap and took your knee circumference then you should have the correct size. Here is a fitting video that you can use to make sure that you are putting the brace on correctly. http://www.youtube.com/watch?v=ZRB7S2Pj2-A
      If the thigh cuff feels too tight it is malleable so you can pull it out a little as well.
  • ali at 10/5/2013 10:49 AM
    • I have this knee injury according to MRI report

      1. Grade I injury of lateral collateral ligament

  • Luke kyi win at 5/9/2013 8:49 PM
    • What are the same and different functions between OA nano and OA full force and OA adjuster3 for moderate osteoarthritis?OA nano can push from degenerated cartilage side to healthy cartilage side or not (meaning function like as OA full force knee brace)?
    • Hello,

      Here are the differences between our OA Knee Braces;

      OA Nano- lightest, newest brace, flexible, provides 10 degrees of correction
      OA Fullforce- designed for athletes, light brace, swooping thigh, 3 degrees of correction
      OA Adjuster-14.5 length, 10 degrees of correction

      Have a Great Day.
  • Keith at 4/26/2012 8:38 AM
    • I have been wearing this brace for about 6 months and it is wonderful. My wife and I enjoy a trip to the beach each summer and I'm concerned about what effect, if any, the salt water and sand may have on this brace. Will the brace be okay if I rinse it well with fresh water (ie. - hose it off) each evening after we return from the beach?
    • Yes, definitely rinse off the brace with fresh water. Make sure to get into the hinges too, to get all the sand out. Let it dry and re-lubricate the hinges with a dry, teflon based lubricant. Most bicycle chain lubricants fit this description.
