Hug Your Knees!
I was a little confused about which was the front and which was the back, but I remembered there was a YouTube video on it. After viewing the video, I was all set. I wore both on my knees two days after wearing just one on my problem knee. My knee felt really good after a day in the sleeve, and both knees benefitted from their hugs within the sleeves. I am very satisfied with the construction of the compression sleeves and the fit is fine for the L size. The sleeves are comfortable to wear and give a little more confidence when walking (stability).
