What is Osteoarthritis (OA)?

Osteoarthritis is a degenerative condition that mostly affects the hands, spine and joints such as hips, knees and ankles, and usually gets worse over time. For a comprehensive overview of OA and information on the various treatment options, please see the excellent resource from Arthritis Australia, MyJointPain.org.au :

  • Around 1.8 million Australians have Osteoarthritis
  • The prevalence of OA rises sharply after the age of 45.
  • Osteoarthritis is more common in women than men.

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, 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 relieve pain by redistributing the weight bearing load on the painful or affected compartment of the joint to the healthy or unaffected compartment. Increased function Studies have shown that wearing an OA brace can increase daily functions and decrease pain. Patients diagnosed with OA who wear a knee brace will generally feel better in the morning, be more active during the day, and rest more comfortably at night.

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.

    • 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.au http://www.betterbraces.com.au/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 21/08/2013 2:01 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 6/08/2013 10:46 PM
    • Do you accept private insurance?
    • Hello Robert,

      Thanks for Contacting Donjoy.

    • 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 11/02/2013 10:05 AM
    • 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 at 12/03/2011 3:19 PM
    • i am disabled and have OA, .Lat. release and total knee replacement (R). Will medicare and my supplement pay for a knee brace like this?
    • Larry,
      Thank you for taking the time to email us here at www.betterbraces.com.au 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,

  • Joyner at 28/10/2010 3:46 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.
