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.

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

OA Knee braces 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.

Product Questions

I am looking at the DonJoy OA Lite Osteoarthritis Knee Brace.

My knee's are more worn on the outside of my knee joints. Which braces do I order, the medial or the lateral?
Question by: Steve Z on Mar 31, 2010, 9:36 AM
If the arthritis pain in your knee is on the outside, you're going to want to offload the lateral (or outside) on both knees. These knee braces are designed to help relieve just that sort of knee pain.
Answer by: Admin on Mar 31, 2010, 9:36 AM
I have OA in left knee and in pain 24/7. I used to play basketball all the time and would like to start again. My ligaments are fine, just no cartilage in fact at age 33 Dr wanted to do total knee. I am 41 now, is there a brace for this?
Question by: Keith on Jan 8, 2014, 5:48 PM
If your doctor told you that you need a total knee replacement you have severe arthritis in your knee and the OA lite if for mild arthitis. Take a look at the OA Adjuster 3. https://www.donjoystore.com/donjoy-oa-adjuster-3-knee-brace This brace is for moderate to severe arthritis, you can play basketball in it. You would need to know which compartment you have the arthritis in so you can order the appropriate brace. The brace has an adjustable hinge that can un-load the side of the knee that hurts and create space between the joint to allow for less pain.
Answer by: Admin on Jan 8, 2014, 5:48 PM
is the oa-lite ok for medial meniscus tear injury. I have sent in this question earlier today but mistakenly indicated a lateral injury. It is a medial tear.
Question by: steve on Sep 9, 2013, 3:20 PM
Yes you would need to oredr a medial unloader.
Answer by: Admin on Sep 9, 2013, 3:20 PM
My MRI after 5 months of therapy revealed:
1. Mild tricompartmental osteoaarthritic changes in the medial tibiofemoral compartment.
2. Degenerative changes and degenerative tear in the medial mensiscus.
3. Mild chondromalacial patella.
5. Mild prepatellar and superficial infrapatellar bursitis.
6 Recent partial rupture of Baker's cyst.

I had fallen down the stairs 3 years ago, recovered well, then last year after 2 weeks of lawn mowing on a bit of slope, couldn't walk. It's pretty good now, but occasional burning or pain. I'm wanting to protect it as I exercise, walk, dow housework, and return to gardening. Should I use a brace?
Question by: Rosalie on Apr 21, 2015, 9:10 AM
It sounds like a brace for mild OA might help when doing those activities. We have the OA Reaction Web Knee Brace which will address all of the issues you have had with the knee. It offers unloading of the medial compartment with a singe upright on the outside for the brace, and will also offer support around the kneecap for the issues with the patella. The brace can help reduce pain on the inside of your knee as well as the front of your knee. https://www.donjoystore.com/donjoy-oa-reaction-web-knee-brace
Answer by: Admin on Apr 21, 2015, 9:10 AM
The features description says this brace "Adjustable pneumatic-condyle pad allows patient to"fine tune" load according to activity level." How do I do this? Please explain better. The directions that came with the brace does not say anything about it.
Question by: Ryan on Oct 22, 2015, 5:04 AM
The brace comes with extra condyle pads that can be added to the side that has the upright so the pressure at the joint will increase the load. The load can also be increased by bending the upright outward away from the leg
