Ossur Unloader Knee brace is one of the best braces for knees. It is lightweight, comfortable, easy to get on and off and helps with Osteoarthritis pain. Please feel free to look it up. This is a size: M and is for the right knee. Women, young women, teens would benefit from a brace like this if they have knee issues, ACL, Miniscus etc. They are very expensive especially if insurance doesn’t cover the whole cost. I have had 3 major knee surgeries and expected to have one more. I have many braces and don’t need all of them. Best offer.
