Otto Bock 8320 Patella Pro Instructions For Use Manual page 11

6) Readjustment (optional) (see fig. 6):
Readjusting at the front: The ratchet hooks can be unhooked from the ratchet straps and
readjusted.
Readjusting at the back: The hook and loop closures on the dynamic tension element (7.3)
can be moved medially or laterally. To do so, first move the two hook and loop straps that are
positioned one over the other as necessary. Then, readjust only the upper hook and loop
strap that is under tension (7.1) and limits realignment.
7) Shorten (see fig. 7): When shortening, note that every ratchet hook requires 2 ratchet straps.
Unhook the ratchet hooks from the ratchet straps and shorten the ratchet straps as necessary
to adapt them. Then round and de-burr the ends.
Tip: Count the number of ratchet positions while the hooks are hooked in and mark the point
to cut. Note that 2 ratchet straps are always required for each hook.
8) Final check: Repeat the functional check through careful flexion and extension within the
range approved by the physician. The orthosis can be readjusted at any time using the addi­
tional 2 pairs of holes in the patella support.
9) If necessary: Use the hook and loop points to attach the additional straps around the top and
bottom edges of the orthosis.
