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.
