Risks of knee braces may include:

  • Discomfort wearing the brace. A knee brace may feel heavy, bulky and hot at first.
  • Skin irritation or swelling. The skin under the brace may become red and irritated if your knee brace fits poorly. Some people also experience swelling around the joint.
  • Lack of benefit. Studies of knee braces for people with osteoarthritis have been limited, and results have been mixed. Some people experience no benefit. Others report diminished pain and increased function.
