Can a knee brace ease arthritis pain?

Braces help some people cope with the pain, swelling, and stiffness of knee osteoarthritis. Examples include a knee sleeve, a compressive or stretchy tube that provides warmth and might help reduce knee swelling; an unloader brace, a long frame that fits on top of the leg and helps reduce pain by redistributing pressure on the knee; and a patella tracking brace, which combines the approaches of both knee sleeves and unloader braces to reduce knee pain, swelling, and pressure at the kneecap (patella).
