Sit in a chair and put on the knee brace. Make sure your kneecap is visible through the patellar hole if your brace has it. The lower strap of the knee brace should sit above the calf muscle. Anchor it and fasten the other straps. Slide two fingers under the straps to check if you have to tighten or loose them up. Walk with your knee brace to check how it feels. Tighten or loosen the straps if necessary.
