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 support a knee affected by OA. They stabilize the joint, help reduce pain 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 help 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.
  • Bracing has come close to eliminating pain for some people with knee OA, while others experience moderate relief.

    • Does health insurance pay/assit?

    • What is the difference in ACL brace and a load bearing unloading brace
    • Our ACL braces are designed to support specifically the ACL in the knee. A brace specific to protecting your ACL reduces the amount of time that your ACL is in an "at-risk" position for tearing. An unloading brace uses a 3 pt load in the frame and hinges to create space between the femur and tibia in a spcific compartment where osteoarthritis is located. Our Unloading braces will also give protection ans support to the ACL. All of our rigid brace have a 4 points of leverage strapping system that will help to protect the knee joint and especially protect the ACL

  • Jan S. at 3/17/2016 9:09 PM
    • I have the OA web brace to unload my lateral compartment right knee. It helps with pain. In October I was 50 % in the medial compartment , damage lateral near bone to bone and now is grinding. Do I assume medial is more than 50% and I read on MRI I have Pateller OA and Spurs. Back on Oct. MD said active hinged brace. Should I use my OA web sometimes and get an action hinged brace too? My Web is DonJoy from this site. thanks
    • You can move to one of our hinged OA braces such as the DonJoy OA Nano. This will provide the support of a active hinged knee brace but you could still unload the lateral side of your knee if needed

    • My Don Joy OA knee brace does not stay up. Continues to fall no matter how tight I make the straps. Any suggestions?
    • Barbara
      You should take the barce back to the practitioner that fit you and see if they can make some adjustments to the brace to help it stay better. The main reasons for this would be that the brace is the wrong size.

    • Jerry
      The OA Nano is for people who are highly active but have moderate OA. You will need to pick the side where the OA is located. Either medial or lateral
  • linda at 10/4/2014 6:22 AM
    • i have moderate oa on the inside(menial)of my right leg.i work full time in retail lifting 20lb items,bending my knees many times with this weight.which brace is the least bulky,seeing that i would need to wear it under my pants.thank you for your responce.
    • Linda
      The OA Full Force and the OA Nano are the lowest profile braces for OA that we have. Both are for moderate OA and are very light wieght, FullForce 20 oz, and the Nano 14 oz. You can order them for the medial compartment of your knee. https://www.betterbraces.com/donjoy-oa-nano-knee-brace https://www.betterbraces.com/oa-fullforce-knee-brace
      If both of these still seem too big for you we do have the OA Reaction Web knee brace that is for mild OA, which is very low profile and would fit under your pants easily. https://www.betterbraces.com/donjoy-oa-reaction-web-knee-brace
  • Eric at 7/26/2014 1:28 PM
    • I had meniscus clean up and in doing so the doctor found out I have very early stages of OA. The OA is on my right knee on the inside. I work in a warehouse so I am looking to get a load bearing brace. I was wondering which one you would recommend for me. Thank you for your time.
    • Eric
      The OA Lite is for those who have mild arthritis. It is a sleeve with a single upright and hinge on the opposite side of the knee in which you would need unloading. In your case you need a medial unloader so the hinge would be on the outside of the brace. The brace comes pre-loaded at 3 degrees of correction. The upright is malleable so it can be bent to allow further load up to 6 degress. https://www.betterbraces.com/donjoy-oa-lite-osteoarthritis-knee-brace The next step up from this brace would be the OA Full Force, OA Nano and the OA Everyday. The OA Everyday is for non-active people, the OA Full Force is for active individuals and the OA Nano is for highly active people. All of these braces are for mild to moderate OA in the knee and have a adjustable hinge that can adjust offloading.
  • Aria at 5/17/2014 9:05 AM
    • Is this price 649.99 just include one adjuster or a pair of adjuster? Like there is a problem with both of my knees, do I need to buy 2 adjusters separately, or this is exactly a pair of it? Thank you!

  • ted at 10/17/2013 8:00 PM
    • I have Lyme disease and my symptoms are severe arthritic pain and I'm wondering which brace you would recommend?
    • Ted
      Thank you for contacting product support. All of our OA braces provide relief to osteoarthitis depending on the severity of OA. The OA Adjuster is for people who have moderate to sever PA and are highly active. All of the OA braces are made to unload the painful compartment of the knee. While the OA adjuster is for moderate to severe OA, the OA lite is for mild OA. All of the other braces kind of fall in between. If you go to our website Betterbraces.com https://www.betterbraces.com/knee-braces/arthritis-knee-braces All of the rigid braces are for OA in one compartment either medial or lateral. If you have general arthritis pain throughout the knee the Reacton knee Brace might work better for you. The web design takes absorbs shock and dispearses it away from the painful areas in the front of the knee. If you do have compartmental OA speak with your physician about which of the rigid braces you might need.
  • Brian at 8/20/2013 9:01 PM
    • I recently had lateral retinacular release survey just over a month ago, and they discovered that I had a partial ACL tear, and a tear in my lateral meniscus. The doctor is trying to get scar tissue to grow around the ACL tear. I want to get back active, I like to jog, cycle, run, and swim laps. Is this a good brace for me. Thank you for your help.
    • Yes this would be a great brace, you would want to order a lateral unloader.
  • Robert at 8/6/2013 5:46 AM
    • Do you accept private insurance?

      Thanks for Contacting Donjoy.
  • Lorraine at 6/10/2013 1:41 PM
    • I have osteoarthritis in both knees and a probable torn meniscus (even with an x-ray, the radiologist and Orthopedic surgeon couldn't tell!), but it was a painful injury and is healing. Even before the injury, I had osteoarthritis, due to various skiing, cycling injuries, and my age (60) The doctor is recommending eventual knee replacement but I want to avoid that by losing weight and using a brace, as well as getting hyuralonic acid injections, which the Dr. is willing to do.

      It will take me a long time to lose the weight I have, given my mobility, but I must try. What sort of brace will take the most pressure off my knees AND provide patellar stability (it sometimes feels hyper-extended) for activities like walking and stationary biking? The ones I've seen for osteoarthritis don't seem to fit round the patella.

      Swimming is also highly recommended. Would I need a different brace for that?
    • Hello, Lorraine -

      The Donjoy OA Adjuster 3 would be the most appropriate choice for your injury and activities.


      You will want to get a 10 degree extension stop installed to assist in preventing hyperextension of the knee.

      If you have further questions, please feel free to contact our product specialists at 888-405-3251.

      Thank you and have a wonderful day!
  • Diane at 2/10/2013 3:05 PM
    • I'm a bit confused by the medial and lateral distinction. I had a minor meniscus tear on the OUTER RIGHT side of my RIGHT KNEE which has healed for the most part, but still gives me some pain. Is this considered a lateral meniscus tear, and would I order a lateral OAdjuster in order to put the load more on the opposite (inner side) of knee, or do I need a medial OAdjuster in order to put the load on the medial side????

    • Hello, Diane -

      You are correct - because you have a lateral meniscus tear, you would want to order a Lateral OA Adjuster Knee brace to unload the lateral compartment of your knee.

      If you have further questions, please feel free to contact us at 888-405-3251.

      Thank you and have a wonderful day!

    • Larry,
      Thank you for taking the time to email us here at www.betterbraces.com regarding our DonJoy OA Adjuster. This product would assist you with off loading your lateral compartment. However, we do not process insurance claims so you'd have to refer to your insurance company to verify if they would cover this product for you. Take care.

    • Hello Larry,

      The product instructions do not indicate how to put the straps back on, but if you give us a call, we'll be happy to grab a product specialist to walk you through it.
  • Joyner at 10/27/2010 9:46 AM
    • will it harm the brace wear at the beach in the sand
    • Hello,

      If you do take your brace to the breach, you must be wary of sand entering the hinge.

      After each immersion in salt water, rinse the brace in freshwater.

      To wash the liners, hand wash in mild detergent and let air dry.
