From the 1st day I got this knee brace, it has just worked wonders. I have arthritis, in my knees that even injections wouldn't help. So I really didn't think I was going to be able to find anything to give me that extra support. I was told by my othro that maybe I should try one. I went and got it that day, and now whenever my knee's get achy I slip it on & It helps me so much. I don't know what I would do without it !!
