IMPORTANT : The center connector(hinge) must be precisely aligned with the knee.
After securing the Brace, take a few steps to check your comfort as well as the
traction strength.
Straps that are too tight can cause poor blood.
Straps that are too loose will not provide the desired traction.

: The length of each strap can also be adjusted
Adjust to the correct length.
Bend the knee in a 90 angle when fastening straps #3 and #4. If the center connector (hinge)
