Donjoy Clima-Flex OA Knee Brace Key Features & Benefits:
- Advanced C-6 Cooling Technology
Standard neoprene braces can cause sweating and skin irritation. The DonJoy Clima-Flex features C-6 technology, utilizing pure carbon threads to naturally repel odor, wick moisture, and regulate temperature. This makes it the ideal choice for warm climates or long days on the golf course.
- Keyless Offloading Hinge
Pain levels fluctuate throughout the day. The Clima-Flex allows you to manage your pain "on-the-fly." The dual-action hinge features integrated dials that allow you to increase or decrease the offloading force instantly. No tools, keys, or professional adjustments are required once the brace is initially fitted.
- Ease of Application (Arthritis Friendly)
Approved by the Arthritis Foundation, the wraparound design and E-Z Grip handles make this brace exceptionally easy to put on, even for those with limited hand strength or finger arthritis.
- Available in size sizes: See Size and Fit tab for sizing chart and measurement/fit help.
- Recommended Manufacturer HCPC: L1851

Which Version Do I Need?
To get the most out of your Clima-Flex OA, you must select the correct compartment to "offload":
- Medial (Inside) Pain: If your pain is on the inside of your knee (closest to your other leg), choose the Medial model.
- Lateral (Outside) Pain: If your pain is on the outside of your knee, choose the Lateral model.
- Note: This brace is side-specific. Ensure you select the correct leg (Left or Right) in addition to the compartment.
Important Fitting Tips
- The "Medial vs. Lateral" Rule: Sizing is independent of the compartment. Whether you need a Medial (Inside) or Lateral (Outside) offloader, the sizing measurements remain the same.
- Donning the Brace: Use the integrated E-Z Grip handles at the top of the brace to pull it into position. The "hinge" should be centered with your kneecap.
- Adjusting the Tension: Once the brace is on, use the keyless dual-action dials to fine-tune the offloading. You should feel a "shift" in pressure away from the painful side of your joint.
Indications
This brace is clinically indicated for the following conditions:
- Mild to Moderate Unicompartmental Osteoarthritis (OA): The primary use case for relieving "bone-on-bone" pain in either the Medial (inner) or Lateral (outer) side of the knee.
- Meniscus Tear & Meniscal Repairs: Provides joint "offloading" to protect a healing meniscus after a tear or surgical repair, reducing the compressive force on the fibrocartilage.
- Chondral Defects: Indicated for localized areas of cartilage damage (focal lesions) where shifting weight to the "healthy" side of the knee can prevent further degradation.
- Post-Op Cartilage Repair: An essential transition brace following procedures such as Microfracture, OATS, or MACI (Autologous Chondrocyte Implantation). It protects the new cartilage graft during the critical remodeling phase.
- Degenerative Joint Disease (DJD): For patients experiencing "start-up" pain or stiffness that improves with light movement and proper alignment.
Ideal Activity Levels
Unlike heavy-duty rigid braces designed for contact sports, the Clima-Flex OA is optimized for low-to-moderate impact activities. It is the premier choice for:
- Golf: The C-6 cooling fabric and flexible design allow for a full rotational swing without the brace "binding."
- Hiking & Walking: The moisture-wicking carbon threads prevent skin irritation during long-distance movement.
- Daily Errands: Its low-profile nature allows it to be worn comfortably under trousers for all-day pain management.
