How to use Ossur Unloader Knee Brace?

 

1. Open Upper (A) and Lower (B) Buckles. Ask patient to sit down and extend leg while fitting the device. Ensure that the Upper (C) and Lower (D) SmartDosing Dials are set to the “0” position. Place the device on the patient’s leg with the Hinge (E) on the affected side of the knee. Ensure proper alignment of the device on the leg (Fig. 2).
   • Height positioning: Align the center of the Hinge slightly above the middle of the patella.
   • Side positioning: Center of the Hinge should be at midline of leg.
2. Fasten the Buckle buttons to their color-matched Keyholes (F, G).
   • Place the blue Lower Buckle button into the blue Calf Shell Keyhole (F) above Buckle Stability Shelf (H) and use the palm of the hand to snap the Lower Buckle closed (Fig. 3). Adjust Calf Strap (I) to appropriate length by tensioning around the calf and folding into the Alligator Clip (J) so that it keeps the device securely and correctly positioned on leg.
   • Bend the patient’s knee to 80°. Place the yellow Upper Buckle button into the yellow Thigh Shell Keyhole (G) and use the palm of the hand to snap the Upper Buckle closed (Fig. 4). Adjust Thigh Strap (K) to appropriate length by tensioning around leg and folding into Alligator Clip.
3. Adjust the length of the Dynamic Force System (DFS) Straps (L, M).
   • With the patient’s knee fully extended, adjust the Upper DFS Strap (L) length until it sits firmly against the leg, and then fold it into Alligator Clip. At this point, patient should not experience any tension or unloading.
   • Adjust the Lower DFS Strap (M) in the same way.
4. Ask patient to bend knee with the foot flat on the floor. Turn Upper (5a) and then the Lower (5b) SmartDosing Dial clockwise until indicators are in the “5” position. Have the patient stand up and take a few steps to verify correct positioning of the device and tightness of the straps.
   • Determine optimal DFS Strap tension based on patient’s pain relief feedback.
   • If patient requires more or less tension with indicator at the “5” position, adjust the length of the DFS Straps accordingly.
   • Aim for final SmartDosing Dial setting at the “5” position since this will give patient the ability to adjust dosing during daily life activities.
5. When final fit has been confirmed, trim the straps to the appropriate length starting with the Calf Strap so that device sits correctly on leg while trimming other straps.
   • Ensure that the Strap Pad (N) is not wrinkled and positioned where the DFS straps cross in the popliteal fossa (Fig. 6).
   • Trim back the straps sufficiently so that the alligator clips are positioned away from the popliteal area. This reduces the bulk behind the knee.
   • Keyhole locks may be inserted into Calf (O) and Thigh (P) Shell if desired to ensure straps cannot accidentally be disengaged from shells (Fig. 7).
