4. Sizing Guide
To ensure the correct fit, measure the circumference of your thigh 6 inches (15.5 cm) above the center of your kneecap. Refer to the sizing chart below. If your measurement falls between two sizes, it is generally recommended to choose the smaller size for a snugger fit and better support.

5. Setup & Application
Follow these steps to correctly apply your NEENCA Hinged Knee Brace:
- Prepare the Brace: Ensure all straps are loosened before application.
- Position the Brace: Slide the brace over your foot and up your leg. Align the open patella design so that your kneecap is centered within the opening.
- Secure Main Straps: Fasten the two main elastic straps, one above and one below the knee, to achieve a comfortable yet secure fit. Do not overtighten.
- Adjust X-Straps: Adjust the innovative "X-Strap" fixing system for a customized fit. These straps are designed to enhance stability and prevent the brace from slipping.
- Check Fit: Bend and straighten your knee a few times to ensure the brace moves comfortably with your leg and provides adequate support without restricting circulation. The hinges should align with the natural pivot points of your knee.

7. Maintenance
Proper maintenance ensures the longevity and hygiene of your knee brace.
- Cleaning: Hand wash only. Use mild soap and cold water. Do not bleach.
- Drying: Air dry completely. Do not tumble dry, iron, or dry clean. Avoid direct sunlight.
- Storage: Store in a cool, dry place away from direct heat and sunlight.
- Velcro Care: Keep Velcro fasteners clean and free of lint to maintain their adhesive strength.
8. Troubleshooting
- Discomfort or Irritation: If the brace feels uncomfortable or causes skin irritation when worn directly, try wearing it over a thin layer of clothing. Ensure straps are not overtightened.
- Brace Slipping: Re-adjust the elastic straps and the "X-Strap" fixing system to ensure a snug and secure fit. Verify that the patella opening is correctly centered over your kneecap.
- Stitching Issues: Avoid pulling the brace up by the open area around the knee. Always use the main body of the brace or the straps for adjustment to prevent stress on the stitching.
- Hinges Squeaking: While uncommon, if hinges develop a slight squeak, ensure they are clean and free of debris. If the issue persists, contact customer support.
