Two years ago, I injured my knee and purchased this new at the hospital. I used it for three days and then left it in a plastic bag. I am selling it now as I no longer need it. It is not new, so please be sure to check the condition in the photos and purchase only if you are satisfied. I haven't noticed any significant stains, but there are two spots. It firmly supports from the thigh to the calf. It has several thin Velcro straps, so you can adjust the support securely. How about this for those who need a spare or for those who are planning to use it for a short period and don't want to buy a new one?? Alcare Co., Ltd. Size S
