While there’s no cure for knee osteoarthritis, a combination of strategies can help
relieve your pain and keep you active.
Although the cornerstones of treatment are exercise and physical therapy — and
pain medications and steroid injections are also options — you can also try knee
braces, shoe inserts or simply wearing more supportive shoes.
“Knee braces can be helpful for managing your pain,” says physical therapist Dawn
Lorring, PT, MPT. “The location and severity of your symptoms will drive which brace
works best for you.”
Osteoarthritis is caused by the breakdown of cartilage (that’s the cushioning material
that covers the ends of bones in joints.) This causes pain and stiffness.
In the knee joint, arthritis can occur at any of three points where the bones come in contact:
- Underneath the kneecap.
- Between the thigh bone (femur) and shin bone (tibia) on the inside of the leg.
- Between the thigh and shin bones on the outside of the leg.
Types of knee braces
Sleeve braces. People who have mild pain or stiffness that limits their activities can
try a sleeve-type brace. These provide compression, which can reduce swelling and
warm the joint. This might relieve the stiffness.
These braces also provide added support. “If your knee feels unsteady or wobbly, a
compression-type brace can be helpful, Lorring says. Some of them have plastic stays
or a hinge on the side, which provides a little more support. She recommends getting
one that has an opening at the knee cap.
Sleeve braces aren’t covered by insurance, but they are relatively inexpensive,
ranging from $10 to 100.
Web brace. A more advanced brace is a sleeve with silicone webbing over the front.
As you bend and straighten your knee, the webbing tightens in certain areas. This
provides extra support to the knee.
A regular sleeve brace provides compression all over. “The brace with the webbing
also provides guidance for how the knee cap moves,” Lorring says.
This type of brace might be the most helpful for someone with osteoarthritis
beneath the knee cap. A web brace costs about $100.
Unloader brace. When arthritic changes are between the femur and tibia, a device
called an unloader knee brace may help, especially if one side is more arthritic than
the other. These have a metal band that goes around the thigh and another one
around the calf, connected by a hinged bar. This creates a frame that can be
adjusted to shift pressure (unload) from one side of the knee to the other.
“If the inside of your knee hurts, the brace can be adjusted to put more force on the
outside of your knee, unloading weight off the inside,” Lorring explains.
These are less beneficial if your arthritis symptoms are similar on both the inside and
outside of the joint.
Unloader knee braces are expensive ($500 to $1,000), but they can be covered by
insurance. You’ll need a doctor’s prescription and documentation that it is medically
necessary.
Shoes and inserts. Various foot problems (like high arches or flat feet) or just the
particular way you walk can affect the alignment of your body. That might be putting
more pressure on your knee joints. You may get some relief by choosing better
shoes or wearing shoe inserts (also called orthotics).
Because everyone is different, there’s no universal advice for shoes or inserts.
Lorring recommends consulting a physical therapist or an expert in foot mechanics
who can observe how you walk and help you pick out shoes or shoe inserts that
match your needs. “I encourage people to look at running shoes because there are
more support options,” she says.
“The goal with orthotics is to make sure your foot is moving in the best way it can so
your knee isn’t getting more force than it should,” Lorring says. There are a wide
variety of shoe inserts and heel wedges that you can buy in a drug store or online.
You can also get them custom made or save some money and get semi-custom ones.
Like with shoes, you need to get inserts and wedges that are specific to your needs.
“You can have an insert that doesn’t add much arch support but it adds cushion,
which can be beneficial if you walk on the outside of your foot,” Lorring says.
“However, if your foot rolls inward too much, you may need more arch support.”
You can get heel wedges that are sloped in one direction or the other, which is
similar to the action of an unloader brace. It shifts pressure from one side of the
knee to the other.
“Ultimately, you have to find what works for you,” Lorring says.
