4. Height positioning: Align the center of the Hinge slightly above the
middle of the patella (Fig. 3).
5. The device is pre-assembled with thick Condyle Pads. There are also
thin and medium Condyle Pads, as well as a hook-and-loop, shim
included with the device. Use any combination of the Condyle Pads
and shim to widen or narrow the width of the device at the knee.
6. The supplied tibial wedge pads can be placed between liner to adjust
the fit around the tibia (Fig. 11). They can also be used to position the
hinge center forward slightly or removed to position the hinge further
backwards (Fig. 12).
Fasten the straps in the following order. All straps can be adjusted
and/or trimmed to length.
7. Fit the Lower Cruciate Strap (B) first, located directly below the knee
(Fig. 4). This strap is located above the calf muscle and aids in the
correct positioning of the device as it helps create the device-to-bone
contact required to help keep the device in place.
8. Next, snugly fasten the Bottom Strap (C) by inserting it through the
D-Ring.
9. Continue with the Upper Cruciate Strap (D), located just above the
knee.
10. Fasten the Top Strap (E). Make sure that the strap hook tab does not
overlap the elastic insert on the strap.
Note: Overtightening the top two straps can cause the device to migrate.
The following modifications come pre-installed, if selected during the
ordering process of the device.
Device Application with ACL Cable System
1. Apply the device according to the device application procedure. The
four straps should be fastened, but the secondary cable strap should
still be loose.
2. Once the device is firmly in place, pass the cable strap through the
smaller D-Ring.
3. Tighten the cable strap to place the desired amount of pressure on the
tibia.
Device Application with PCL Strap Kit
1. Remove the Lower Cruciate Strap pad, attach the PCL pad onto the
straps below the knee.
2. Apply the device according to the device application procedure.
3. Tighten the PCL strap with the leg in full extension so that the strap
and pad are comfortably snug. The pad should be centered within the
frame. If the PCL strap is too long, trim the strap on the alligator tab
side. Replace the alligator tab and fasten. Make sure that the alligator
tab is under the pull tab.
Device Application with Ski Boot Attachment
1. Apply the device according to device application procedure.
2. Apply ski boots, ask the patient to bend his knees and lean forward as
though skiing. Position the bottom bearing of the aluminum rod on
the hard plastic shell of the boot and mark the bent leg position of the
bearing (Fig. 15).
Note: this mark should be positioned to allow for at least ½" (13mm)
of plastic shell surrounding it on all sides.
3. Remove the boot and device and drill a 3/16th" (5mm) hole at the
spot marked on the boot. Use care so as not to drill the tongue and
the shell (Fig. 16).
