Knee braces are consumable protective products. Elastic fibers gradually lose strength over time, depending on usage frequency (e.g., daily running vs. occasional walking).

General guideline: With proper care, a knee brace typically lasts 6 months to 1 year. If the brace starts slipping or no longer provides adequate support, it’s time to replace it.

To protect the elasticity and internal components, hand washing is recommended. Wash with cold or lukewarm water and air dry naturally. Do not bleach, iron, or dry clean.

Because our products provide medical-grade compression, mild pressure marks on the skin after removal are normal and usually disappear within a few minutes.

Regarding itching: This is more common after exercise when sweat accumulates between the skin and silicone strips, which may cause irritation.

Recommendations: Remove the knee brace promptly after exercise, clean your skin, and allow the brace to air dry.

Warning: If you experience persistent redness, rash, or a severe allergic reaction, discontinue use immediately and consult a physician.

This depends on the reasons that you are wearing a knee brace. In case of a knee injury, you will typically need to wear a knee brace for at least a week after the date of the damage. If your goal is to prevent knee injuries during sports, wear it every time you are engaged in activities that might cause harm to your knee. Please speak to a healthcare professional for osteoarthritis and post-operative braces for further instructions.

Knee braces can be a helpful therapeutic device to provide pain relief. A person or their doctor may consider a knee brace to help with one or more of the following problems:

1. Overuse injury to the knee
2. Acute injury to the knee
3. After surgery
4. Support for osteoarthritis
5. Prevent injury

The brace must be snug but not too snug, so no compression is applied to support your knee. However, if you strap the brace too tightly against your leg, the leg brace may potentially cut off blood circulation and cause severe discomfort. It is also important to have the correct length for your height and injury type.

The right knee brace can effectively relieve pain associated with knee injuries and conditions such as osteoarthritis. They can remove the pressure off the affected area, apply adequate compression to reduce swelling, warm the joints to soften the tissue, and provide physical support to an injured knee that is weak and unstable. Braces can be used alongside other pain relief medications to manage overall knee pain effectively.

You can run, exercise, and engage in sports with knee braces without any fear of harm. Knee braces exist to prevent knee injuries, provide knee support, and aid injury recovery.

Yes. All you have to do is ensure that the pants fit without compressing your muscles, and you're good to go!
