My knee brace makes my skin sweat and itch in the heat. What can I do?

Why it happens

Neoprene and padded liners hold heat and moisture against the skin. Walking between air-conditioned buildings and the outdoor heat makes you sweat more, and straps rub in the same spot all day. The result is itching, redness, small spots around hair follicles and, sometimes, broken skin behind the knee or under straps.

Practical steps that help

• Wear a thin, breathable cotton or moisture-wicking sleeve under the brace
• Keep the skin clean and fully dry before putting the brace on
• Wash the liner or sleeve regularly and let it dry completely
• Check the skin every day, especially behind the knee and under straps
• Avoid heavy creams under the brace, which trap more moisture
• If your surgeon allows, remove the brace for short breaks indoors to let the skin breathe

After surgery, follow the rules first

If the brace protects a recent repair, do not take it off or change settings without your surgeon's advice. Ask whether it can be removed while sitting or lying, and how to protect the wound from sweat. A brace that fits poorly can sometimes be adjusted or swapped for a different size.

Warning signs to act on

Remove pressure and seek advice for skin that blisters, breaks or oozes, spreading redness with warmth, fever, or a wound that becomes red or leaks. Take the brace off and get urgent help if your foot becomes numb, cold, pale or blue, or the calf swells and hurts. At Aman Hospital, the team can check the skin, the brace fit and the knee.
