Open all straps and pull them through the belt eyes. In order to prevent the the Velcro® from causing damage to clothing, for example, fold the end of the strap back on to it.
Pull the knob out of the tibia support. A click confirms the correct position. Pull the tibia support out towards the back until it stops. Bend your leg to ~70° and put the that you have put the brace on properly. The brace has been put on properly if the joint centres are located at the top edge of the kneecap and they are positioned slightly behind the side central line of the leg. Now fasten Belt No. 3 for the thigh and pull it tight. Make sure that you don’t position the brace too far forwards.
Turn the knob back in to activate the turning mechanism. Another click will confirm the correct position. Now turn the wheel to the extent that the tuberosity of the tibia (protruding bone at the top end of the shin) is level with the one on the healthy leg.
When required and for purely stabilising purposes, please fasten the tibia belt. This must always be the last belt to be fastened.
Now move the knee lightly a few times and check again that your have put the brace on properly. Make any necessary corrections.
The indicators on the side on the guide bars may be used as a reference point for the position of the tibia support.
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.
