DonJoy® OA Reaction Web Knee Brace for Osteoarthritis

Keep moving through early knee osteoarthritis with the DonJoy OA Reaction Web, one of the lowest-profile osteoarthritis knee braces available. Its open, lightweight design gently offloads the painful side of the knee and cushions the joint, making it an easy first brace to live with day to day - discreet enough to wear under everyday clothing or with exercise wear.

Patented Silicone WEB Technology

An integrated silicone web in a hexagonal design creates gentle air pockets that support the knee, absorb shock and help relieve pain at the front of the joint. The open elastomeric framework keeps the brace light and breathable while cushioning the knee as you move.

Gentle Offloading

A silicone condyle pad sits over the affected compartment to gently offload the knee with a secure, non-slip effect, while supporting your natural sense of the joint's position. A single lightweight aluminium upright adds stability and can be adjusted to increase the level of offloading. The brace is supplied for either medial or lateral relief, so it targets the side causing your pain.

Easy, Custom-Like Fit

A four-way adjustable wraparound design gives a snug, custom-like fit that won't slip, and it's easy to apply over the fitted undersleeve supplied with the brace. Moisture-wicking fabric and padded cuff liners keep it comfortable for all-day wear during mild-to-moderate activity such as walking, golf or hiking.

FAQs

What is the OA Reaction Web used for?

It is designed for early to mild one-sided (unicompartmental) osteoarthritis of the knee and kneecap, with an emphasis on relieving pain at the front of the knee. It is a lightweight, everyday brace for mild-to-moderate activity.

Which side and size do I need?

Choose the configuration that offloads your affected compartment (medial or lateral). For size, measure your thigh circumference 15 cm (6") above the middle of your kneecap and compare it with the size guide. If you're between sizes, size up, or contact us for help.

How long each day should I wear it?

The open, low-profile design is made for all-day wear. Build up your wearing time gradually and wear it for the activities where you need support. Follow your clinician's advice for your situation.

Can I exercise while wearing it?

Yes. It's intended for everyday activity such as walking, golf and hiking. Gentle exercise is generally helpful for osteoarthritis; ease off if you feel discomfort and seek advice if pain persists.

Does it come with an undersleeve?

Yes - a fitted undersleeve sized to the brace is included, worn under the brace for comfort and a secure fit.
