How to Replace or Move the Field-Serviceable D-Rings
D-Rings can be moved from the interior to the exterior or replaced if broken.
Moving a D-Ring from the interior to the exterior:
1. Remove strap from D-Ring.
2. Bend D-Ring mounted on the device interior, push it inwards to
release it from the keyhole lock and remove it from the rivet (fig. 6).
3. Attach D-Ring to the device exterior by pushing down onto the rivet
through the keyhole lock. Slide and click D-Ring into place. Place
keyhole lock with indented side facing up (fig. 7).
4. Replace strap. If needed, repeat steps for other D-Rings.
Range of Motion (ROM) Adjustment
The device has 0° extension stops attached to the hinges. If needed, the
range of motion can be adjusted using the extension and flexion stop kits.
1. Lift and turn tab 90° (fig. 8).
2. Remove existing stop if necessary, by pulling on the lower edge of the
installed stop (fig. 9).
3. Insert desired flexion/extension stop with the number facing the
opposite direction of leg (fig. 10).
4. Return tab to initial position and press downward to lock in place
(fig. 11).
5. Follow the same procedure to change any additional stops and repeat
on the opposite hinge.
PcL Strap attachment
The PCL kit is designed to counteract posterior subluxation of the tibia.
1. Take the end of the PCL strap with the alligator clip and loop it through
the PCL Slot (H) on the device's upper frame (fig. 12). The alligator clip
will close on the inside of the strap. Trim strap if necessary.
2. Loop the other end of the PCL Strap through the device frame. Fasten
the strap and secure it onto the outside of the strap.
Note: Trim and adjust the PCL strap for proper fit.
3. Place the adjustable pad in the middle of the strap (fig. 13). Trim the
strap pad if needed.
4. Fully extend the leg. Tighten the strap, securing the pad.
Device Removal
1. Sit down and bend the knee to between a 30° - 45° angle.
2. Unfasten the posterior straps on the upper frame and the anterior
straps on the lower frame of the device and attach the straps back to
themselves. This will make it easier to put the device on next time and
will also prolong the life of the straps.
3. Slide the device off the leg.
