Page 6: Alignment And Set-Up
7 Alignment and Set-Up Users be aware of potential finger trap hazard Note: 4-bar knees inherently are very stable due to the geometry built into each design. This is commonly referred to as the Instant Knee Center (IKC). The IKC point when doing bench alignment, will fall behind the traditional TKA line that we will reference. - Page 7 b) Ideally, the pylon connecting the knee and foot should end up vertical. Of course, there may be a variance due to the foot alignment recommendations. In this case, the maximum anterior tilt of the pylon should not to exceed 4 degrees, and it may be necessary to utilize offset adapters like the 1222T off set tube clamp c) The weight line should pass through the centerline of the knee in the Coronal or M/L plane (Fig.
- Page 8 8 Knee Adjustment 8.1 Stance Flexion Adjustment NOTE: Stance Flexion set screws have been eliminated. The threaded holes remain, but will not contain a screw. Stance flexion adjustment screws are located on the anterior body of the knee and can be adjusted with a 5mm wrench. Turning both screws clockwise decreases the 5th axis motion, reducing the stance flexion angle.

- Page 10 Attachment of Lanyard Handle Star Nut: The Star Nut needs to be laminated into the socket. Depending on the nut supplied, the hole should be burnished through, and then: If the Star Nut is not threaded, drill out with 3.3mm drill bit and tap with 4mm tap. If the Star Nut is threaded, chase threaded nut to clean thread with 4mm tap.
- Page 11 Apply Masking tape over the whole area to enable a smooth and relatively flat blended in surface – if the rivet sticks through the tape, that is ok. You want to be sure that the Star Nut is completely covered so it stays in place when the hole is either chased, or drilled and tapped.
- Page 12 For Unlocked gait Deviations GAIT DEVIATIONS AND ADJUSTMENTS: Excessive Heel Rise: During walking, first try adjusting the knee friction adjustment by turning it up to slow knee flexion initiation during swing. It might be necessary to very slightly increase knee extension assist spring tension by 1/8 turn increments. Increasing extension assist spring tension alone, will not reduce excessive heel rise tendencies.

9. Knee Maintenance 9.1 Changing Various bumpers: For the knee head leveling bumper, use 2mm wrench driver to loosen the bumper set screw by turning anti- clockwise. Note: Indicate position of the screw prior to removal of the bumper. Push out the bumper by turning the 5mm hex screw clockwise. - Page 14 9.2.2 Changing Stance Flexion Bumper Use 4mm driver to loosen the screws of fourth and fifth axes to take out the side bars of stance flexion unit. Please refer to the picture below – (1324 Knee used for reference only) Pull out opposite side bar along with fourth and fifth axes.
