Donning/fitting instructions

Open all the straps. Sit on the edge of a chair, pull the brace up the affected leg and flex your
knee to 45°. Position the joints so that the centre of the joint (extension wedges’ height) is positioned at the level of the top edge of the kneecap and slightly behind the leg’s side central line. Please make sure that the brace has been placed on the leg straight and is not twisted.
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.
Now move the knee lightly a few times and check again that your have put the brace on properly. Make any necessary corrections

Wearing directions

Only change the extension and flexion limits on instruction from your doctor or orthotist. In order to prevent hyperextension, always insert extension wedges or 0° wedges. The wedges define the exact excursion of the orthosis. In difficult soft-tissue conditions, e.g. where the soft-tissues are under compression, it may be necessary to insert the larger wedge to limit the joint movement to the desired excursion. In addition, make sure that the orthosis joints are correctly positioned: the middles of the joints should be level with the upper border of the patella. The joint must lie behind the midline of the leg.
Shaping the orthosis
When shaping the orthosis, please ensure that the joints stay parallel. This guarantees that the orthosis will function well and run easily and that there is no excessive wear.
Fastening the belt eyes
The belt eyes have been adequately fastened and are, to some extent, deliberately mobile. Please do not tighten the screws; they are tight enough. If you apply too much force, you can break off the screws.
