Donjoy OA Reaction Web Unloader Knee Brace is an entry level knee brace for those suffering from the early stages of osteoarthritis (OA) and chronic knee pain. Designed to off-set pressure and support the patella, the brace uses medical grade silicon which has been anatomically designed to extend and retract with various leg movements.
For this type of knee brace, you need to know which part of the knee has arthritis and which side you want to unload. First, select the side you want to unload (the arthritic part of the knee). For example, selecting the Medial / Inside will unload the medial compartment of the knee which is the part that has arthritis. See the blog What knee compartment to unload for more information.
You then can use the chart below to select the size of the brace.
We review all prescriptions before shipping your purchase out. If the prescription has any issues, we will contact you to clarify the issue.

Donjoy OA Reaction Web Unloader Knee Brace is an entry level knee brace for those suffering from the early stages of osteoarthritis (OA) and chronic knee pain. Designed to off-set pressure and support the patella, the brace uses medical grade silicon which has been anatomically designed to extend and retract with various leg movements.
As of this year, 8.5 million people are afflicted with Osteoarthritis. A staggering 175 million people are affected by it worldwide. OA is a degenerative disorder in the knee that affects the cartilage and can be brought on by a number of factors ranging from post-operative stress, sporting trauma, or even old age. The gradual wearing away of cartilage results in painful movements and distorted joints as the body tries to repair itself.
While there is no cure for it as of yet, knee braces can aid in slowing the degeneration and provide suitable pain relief for OA sufferers.
Donjoy OA Reaction Knee Brace uses a number of techniques to relieve OA pain. The most notable is the patented open web design, which features a network of durable, high grade silicon that wraps around the knee to provide appropriate shock absorption and support. The silicon absorbs and releases kinetic energy, allowing the wearer to regain confidence in their movements and stay active.
The brace also uses two silicone condyle pads that support the knee on either side. Non-slip and secure, the condyle pad uses a hexagonal design to create an air pocket which holds closely to the skin. These pads not only aid in pain relief, but also off-load any extra pressure being placed on the affected compartment.
Lightweight, breathable, and discreet, the Donjoy OA Reaction Knee Brace comes with a fitted undersleeve to gently compress the skin to increase blood flow and promote recovery. Combined with contoured back pad, straps, and moisture wicking material. It becomes clear that this knee brace has been designed with maximum comfort in mind.
An unloader knee brace unloads stress from the affected joint. Most often, unloader knee braces are prescribed for those with medial compartment knee osteoarthritis (affecting the inner portion of the knee).
When you walk, if you have medial knee osteoarthritis, the instability in the knee can be obvious to someone who is watching you walk — the knee actually wobbles towards the inside. Usually the affected leg has a bow (bow legged, genu varus).
Some designs of unloader knee braces can unload either the medial (inner) or lateral (outer) part of the knee — just by adjusting the unloading hinge. This takes stress and unloads the side of the knee that has the arthritis, taking the pressure off and helping re-align the knee. This can help reduce pain, inflammation and help you walk better.
To find out what size you need, please measure the thigh circumference 6″ above the middle of your kneecap.
| Size | Thigh Circumference |
| Small | 15.5″ – 18.5″ (39 – 47 cm) |
| Medium | 18.5″ – 21″ (47 – 53 cm) |
| Large | 21″ – 23.5″ (53 – 60 cm) |
| X-Large | 23.5 – 26.5″ (60 – 67 cm) |
| XX-Large | 26.5 – 29.5″ (67 – 75 cm) |
| XXX-Large | 29.5 – 32″ (75 – 81 cm) |
