Make sure that the brace is not twisted on your leg.
First fasten the lower front calf strap, then the upper back thigh strap. Keep your knee in a flexed position and push both joints towards the back of the leg.
Now fasten the lower back thigh strap.
Make sure that you do not have the hinge joints positioned in front of the midline of the leg.
Now fasten the upper front calf strap.
Then the upper back calf strap, and finally the front thigh strap.
Bend your knee slightly a few times and refasten the straps again in the order described above to prevent the brace slipping.
