I had knee surgery on my right knee many years ago. Now my left knee is painful at times and probably needs the same surgery. However, I don't have the time or money for another surgery and I have to go up and down stairs in my job which is pretty painful at times. This brace provides good support and pain relief. The only thing I would change about it is the fabric that comes in contact with my skin. It Itches. If I put it on over leggings it's fine. Because it works well I'm willing to wear leggings.
