Knee Braces Are Treatment Option for Osteoarthritis
Knee braces are another way to provide stability, support, and pain relief for patients with knee osteoarthritis. It has been estimated that about 10 million Americans have been diagnosed with knee osteoarthritis. Other common treatment options include:
- Medications (such as nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids)
- Lifestyle modifications (including weight loss and strengthening exercises)
- Joint protection techniques
- Assistive devices
- Joint surgery is considered a last resort treatment option
Patients should consider trying a knee brace to see if there is noticeable benefit. The knee brace would be a complementary treatment, to go along with any other treatments being used. Knee braces should not replace other treatment options.
The Appropriate Knee Brace for You
There are different kinds of knee braces and it's important for your doctor or a health professional to help decide which knee brace might be appropriate for you. Three knee components to consider are:
- medial (on the inside of the knee joint)
- lateral (on the outside of the knee joint)
- patellofemoral (behind the kneecap)
Usually knee braces are recommended for patients who have cartilage loss in one component of the knee, also known as unicompartmental knee damage. Osteoarthritis most commonly develops in the medial component.
Types of Knee Braces
Single-piece sleeves made of neoprene, an elastic-rubbery material, are the most simple knee braces. The knee brace is pulled on over the foot of the affected leg and is placed over the knee where it provides compression, warmth, and support. This type of knee brace is for mild to moderate osteoarthritis and it is available over the counter in most drug stores. The fit should be snug.
An unloader brace is a semi-rigid knee brace made from molded plastic and foam. Steel struts inserted on the sides limit lateral knee movement and add stability. This brace is custom-fit to each individual patient for whom it is prescribed (usually patients with medial component osteoarthritis). Essentially, it relieves pain by transferring pressure from the inside to the outside part of the knee.
The unloader knee brace can also be designed for patients with cartilage damage in the lateral component of the knee, as well as patients with severe osteoarthritis of the knee who are looking for temporary pain relief while they wait to have knee replacement surgery. To purchase an unloader knee brace, the patient must obtain a prescription from an orthopedic doctor, and the brace must be purchased at a store specializing in orthotics.
Experts suggest that patients allow a week to one month to adjust to how the unloader brace feels. Right from the start, don't expect comfort. It takes a little time. Experts also warn patients about becoming too reliant on the unloader brace. Take it off from time to time so you can exercise and strengthen muscles. It's also important to remember that a knee brace is just one part of a patient's treatment regimen. Don't disregard other aspects of your treatment regimen without first talking to your doctor.
