Knees are one of the most complex joints in the body. This complexity often leads to problems, which in turn lead to pain, swelling, and other issues. If your knees are swollen and painful due to bursa sacs or knee efflusion (water on the knee), then check out the selection of braces on this page. We have a variety of knee braces that can compress, heat, and cool your knees to help make the swelling go down. These braces may be especially useful if you have been unsuccessful with trying different forms of compression and temperature therapy. Wraps and ice packs are mildly effective, but these knee braces were specifically engineered to compress, heat, or cool the joint to reduce swelling quickly.
