Use & Adjustment

The extension stops are used with the CTi®3 hinge system to adjust and limit the knee's extension range of motion. They can help prevent the knee from extending beyond the selected range.

Installation & Replacement

Install the appropriate extension stops according to the CTi®3 brace instructions and the desired range-of-motion setting. Replace the stops if they become worn, damaged, or lost.

For prescribed range-of-motion restrictions, follow the settings recommended by your healthcare professional.
