2. Safety Information
Important: This device is intended for use under the guidance of a healthcare professional. Improper application or adjustment may result in injury or discomfort. Always consult your doctor or therapist regarding the appropriate use, fit, and range of motion settings for your specific condition.
- Do not overtighten straps, as this may restrict circulation or cause skin irritation.
- Discontinue use and consult a healthcare professional if you experience increased pain, numbness, swelling, or skin discoloration.
- Keep out of reach of children.
- Inspect the brace regularly for wear and tear. Do not use if components are damaged.
3. Setup and Application
3.1 Sizing and Initial Adjustment
Before applying the brace, ensure it is correctly sized for your leg. The brace features an adjustable frame to accommodate various leg lengths. Measure your thigh circumference; this brace is designed for thigh circumferences up to 27 inches. Adjust the telescoping uprights to match your leg length, ensuring the hinges align with your knee joint.

3.2 Applying the Brace
- Position the Brace: Sit or lie down comfortably. Place the brace on your leg, ensuring the hinges are aligned with the center of your knee joint. The pads should rest comfortably against your skin.
- Secure the Straps: Starting from the straps closest to the knee, wrap and secure each strap firmly but not too tightly. Ensure the D-ring strap system is snug. Work your way up and down the leg, securing all straps.
- Check Fit: The brace should feel secure and stable without causing discomfort, pinching, or restricting circulation. You should be able to slide one finger under each strap.

4. Operating the Range of Motion (ROM) Hinges
The Ossur Post-Op Knee Brace features Innovator Hinges that allow for precise control of knee flexion (bending) and extension (straightening). Your healthcare professional will provide specific ROM settings for your recovery plan.
- Adjusting Extension: To set the extension limit, locate the extension adjustment button on the hinge. Press the button and rotate the dial to the desired degree of extension (e.g., 0°, 10°, 20°). Release the button to lock the setting.
- Adjusting Flexion: To set the flexion limit, locate the flexion adjustment button on the hinge. Press the button and rotate the dial to the desired degree of flexion (e.g., 90°, 100°, 110°). Release the button to lock the setting.
- Locking the Brace: If full immobilization is required, set both flexion and extension to 0° or as instructed by your healthcare provider. The hinges can be locked with zip ties for tamper-proof settings, if necessary (refer to Figure 2 for zip tie location).
Always follow your healthcare professional's instructions for ROM settings.
