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?

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.

Will I be able to ride a motorcycle ?
Question by: Alfred Kaiser on Sep 13, 2010, 9:16 AM
Hello Alfred,

The DonJoy OAdjuster Osteoarthritis Knee Brace should not prevent you from your normal activities.
Answer by: Admin on Sep 13, 2010, 9:16 AM
will it harm the brace wear at the beach in the sand
Question by: Joyner on Oct 27, 2010, 9:46 AM
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.

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.

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?
Question by: Lorraine on Jun 10, 2013, 1:41 PM
Hello, Lorraine -

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

https://www.donjoystore.com/donjoy-oa-adjuster-3-knee-brace

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!
