Product Overview
The Zamst RK-1 Knee Brace is designed to provide support and stability to the knee, specifically targeting the prevention of Iliotibial band friction on the femoral condyle. Its advanced design aims to alleviate pain and allow for natural, fluid running movements. Constructed from ultra-thin and breathable materials, the RK-1 ensures optimal comfort during use. The brace features semi-rigid stays for enhanced stability and a 3-D conception with a butterfly shape on the back for improved flexion and adjustment. A bi-component anchor pad on the lower tibia helps maintain brace stability and strapping efficiency.

Setup and Application
Proper application of the Zamst RK-1 Knee Brace is essential for optimal performance and comfort. Follow these steps to ensure correct fit:
- Identify Orientation: Ensure the brace is oriented correctly with the Zamst logo facing forward and the wider section positioned above the knee.
- Position on Knee: Slide the brace onto your leg, centering the patella (kneecap) within the designated opening or soft area of the brace. The semi-rigid stays should align with the sides of your knee.
- Secure Lower Strap: Fasten the lower strap, typically located below the knee, ensuring it is snug but not overly tight. The bi-component anchor pad should rest securely on the lower part of the tibia.
- Secure Upper Strap: Fasten the upper strap, located above the knee. Adjust for a comfortable and secure fit that prevents slippage during movement.
- Adjust for Comfort: Flex and extend your knee a few times to ensure the brace moves naturally with your leg. Make any minor adjustments to the straps to achieve a comfortable yet supportive fit. The butterfly shape on the back is designed to facilitate flexion.
The brace should feel supportive without restricting circulation or causing discomfort. If you experience pain or numbness, readjust the brace or consult a medical professional.

The Zamst RK-1 Knee Brace is designed for use during physical activities, particularly running, to provide support and help manage Iliotibial band friction. While wearing the brace:
- Activity Level: The brace is suitable for various levels of physical activity. Its design allows for a natural range of motion.
- Comfort Monitoring: Periodically check for comfort and proper positioning during extended periods of use. Adjust straps as needed.
- Skin Care: Ensure your skin is clean and dry before applying the brace to prevent irritation. If skin irritation occurs, discontinue use and consult a healthcare professional.
- Intended Use: This brace is intended to provide support and reduce discomfort associated with Iliotibial band friction. It is not a substitute for medical diagnosis or treatment.
Maintenance and Care
Proper care will extend the life of your Zamst RK-1 Knee Brace and maintain its effectiveness:
- Washing: Hand wash the brace in cold water with a mild detergent. Do not use bleach or harsh chemicals.
- Drying: Air dry completely. Do not tumble dry, iron, or dry clean, as this can damage the materials and elastic properties.
- Storage: Store the brace in a cool, dry place away from direct sunlight when not in use. Ensure all hook-and-loop fasteners are secured to prevent them from snagging other fabrics.
- Inspection: Regularly inspect the brace for signs of wear and tear, such as frayed edges, stretched fabric, or damaged fasteners. Replace the brace if its integrity is compromised.
Troubleshooting
If you encounter issues while using your Zamst RK-1 Knee Brace, consider the following:
| Issue | Possible Cause / Solution |
|---|---|
| Brace slips down during activity. | The straps may not be tight enough, or the brace is not positioned correctly. Re-adjust the upper and lower straps for a snugger fit. Ensure the bi-component anchor pad is properly seated on the tibia. |
| Discomfort or pinching. | The brace might be too tight or misaligned. Loosen the straps slightly and reposition the brace. Ensure no fabric is bunched up behind the knee. If discomfort persists, discontinue use. |
| Skin irritation or redness. | Ensure the skin is clean and dry before application. The brace might be too tight, or you may have a sensitivity to the material. Discontinue use if irritation persists and consult a healthcare professional. |
| Brace feels ineffective. | Verify that the brace is correctly sized for your leg and applied according to the setup instructions. Ensure the semi-rigid stays are properly aligned. If the issue persists, consult a medical professional for advice on appropriate knee support. |
