Secure on Femur • Expose knee. • Place knee in flexion and seat microblock on femur

in approximately neutral varus/valgus and flexion/extension position.

• Insert headed pin in center hole of microblock slider and drive it into most distal point of sulcus of trochlea, directing it toward center of femoral head.

TIP: A typical IM drill placement approximates this point. Do not bias medially or laterally.

• Rotate microblock to approximately line up with Whiteside’s line.

• Slide microblock in anterior/posterior direction as necessary to achieve three-point contact to femur. Pin medial and lateral feet of instrument against condyles, using headed pins provided in instrument tray.


Hardened, stainless steel headed pins provided in instrument tray should be used.

Do not impact or hammer system components.

TIP: Verify that there is approximately 10 mm of clearance between femoral cutting block and anterior condyles.

Input A/p Offset • Read anterior/posterior offset position of center pin

on microblock slider scale. • Enter offset value into navigation unit by pressing

right button until correct number is displayed on bottom right corner of screen.

TIPs for Maneuver: Maneuver must be completed before beeping stops

and as rapidly as possible.

TIP: Maneuver leg using two hands, grasping behind knee and ankle. Do not hold navigation unit or femoral jig.

Rotate knee between 10° and 45° subtended during registration maneuver.

For accurate results, it is important that hip is kept stationary during registration. Knee must be returned to start position (within ± 2 cm and ± 5° rotation).

TIP: Following maneuver completion, during hip point calculation, navigation unit screen will provide user with feedback on speed of maneuver in medial-lateral (M/L) and anterior-posterior (A/P) planes. Green bars displayed for a given plane indicate that speed of the maneuver is sufficient in that plane. Red bars displayed for a given plane indicate that speed in that plane is insufficient.

TIP: In the event maneuver is too slow in a given plane, or otherwise insufficient, navigation unit screen will provide instructions to repeat maneuver.

maneuver Leg • Hold femur stationary until green light appears

on navigation unit screen and unit starts to beep continuously. As soon as navigation unit starts beeping, maneuver femur rapidly as follows while keeping the pelvis stationary:

• First, move knee in medial-lateral arc by internally and/or externally rotating hip while keeping heel on table, and maintaining knee in flexion.

• Next, move knee in sagittal plane by flexing and extending hip.

Flex/Extend hip Return gently to Start Position, hold Still

Femur

Set resection plane • Set desired varus/valgus and flexion/extension angles

using ball driver to adjust microblock’s navigation screws. • Press center button when completed.

TIP: Navigation unit must be oriented within its operating range in order for unit to display resection angles.

TIP: Varus/valgus and flexion/extension angles are measured relative to mechanical axis of femur.

Do not attempt to adjust cutting block orientation by applying force to jig. Angles must be adjusted using ball driver to adjust screws prior to pinning the cutting block.

Applying excessive torque to adjustment screws at limit of travel will cause damage to microblock.

If bone interferes with cutting block while setting resection angle, microblock has been pinned in too much flexion. Two alternatives may be considered:1. Use sagittal saw to trim interfering bone to provide

additional travel for cutting block. Care should be taken not to remove too much bone, which could cause notching or interfere with subsequent sizing.

2. Unpin microblock and re-pin closer to neutral flexion angle, repeating Femur–Steps 1-4.

Set resection Depth • Remove navigation unit/bracket assembly, and sensor

from microblock. a Attach distal guide to microblock guide rod by

squeezing pushbutton (b), and slide distal guide to desired resection depth (c).

d Press gold latch on side of microblock to unlock guide rod/cutting block assembly from its maximum anterior position. Position distal guide paddles flush against condyles, and slide cutting block posteriorly to contact femur.

e Pin distal femoral cutting block to anterior femur using most proximal holes using headless pins provided in instrument tray.

f Remove pins from microblock by pulling in distal direction, while securely holding cutting block in place. Fix cutting block with oblique pin if desired.

g Resect distal femur. • Press center button when completed.

Set resection Depth (cont.)

TIP: Resection depth is indicated by scale on anterior face of guide rod, viewed at top of distal guide. Shoulder on guide rod stops distal guide at 9 mm resection depth. Resection depth can be increased in 1 mm increments by squeezing pushbutton and pulling distal guide up.

Resection depth measurement should be set according to implant manufacturer’s recommendations.

Resection depth scale is relative to position of distal guide. Ensure that distal guide paddles remain flush on highest point of condyle being referenced.

TIP: When pinning the cutting block, take care to avoid applying excessive force that could alter intended varus/valgus and flexion/extension angles.

To prevent potential interference of oblique pin with microblock pins, do not insert oblique pin until microblock has been removed. Use angel wing stylus to verify resection level prior to resection.

TIP: If more bone needs to be resected, move cutting block proximally on parallel pins (+2mm, +4mm). Required saw blade thickness is 1.27 mm (or 0.050 in).

Midline probe should not be impacted into tibial plateau.

During pinning, ensure that midline probe is not pulling away from main tibial jig body. If it has, push probe down to reseat.

After pinning, fixation arm should be inspected to verify it has not pulled away from main tibial jig body and that it is seated fully within notch in jig body. If fixation arm has disengaged from jig body, push jig towards tibia to fully reseat fixation arm in jig body.

TIP: Hardened, stainless steel pins provided in instrument tray should be used for pinning KneeAlign® 2 instrumentation.

TIP: If jig appears in extension relative to tibia, remove shin spacer. This may be the case for very obese legs.

Hold knee steady before beginning maneuver.

Hip point registration maneuver performed too slowly in either, or both anterior/posterior (A/P) or medial-lateral (M/L) planes. Press center button to repeat maneuver at higher speed sufficient to obtain green color bars for both A/P and M/L speeds.

Hip point registration maneuver not finished prior to end of navigation unit beeping stream. Press center button to repeat maneuver, finishing maneuver and returning knee to starting position prior to end of unit beeping stream.

Knee was not returned to starting position at end of maneuver. Press center button to repeat maneuver, returning knee to within ± 2 cm and ± 5° rotation of starting position prior to end of unit beeping stream.

During hip point registration, software conducts a check for consistency of data throughout the maneuver. Inconsistent data triggers a rejection of registration. This can be caused by movement of pelvis, inadequate fixation of microblock to femur or excessive deceleration when heel is repositioned at the end of maneuver. If maneuver was conducted without these errors, press right button to proceed. Press center button to repeat maneuver if desired, ensuring the following:• Use three headed pins (provided with KneeAlign® 2 System) to mount the microblock

to femur. Ensure microblock is secured with firm, three-point contact to femur.• At end of hip point maneuver, place heel down gently.• Stabilize pelvis during maneuver and ensure femur is free to move through full range

of motion.

DescriptionAppropriate placement and fixation of the femoral jig is necessary for system function. Placing the jig either in too much flexion or in too much extension can result in subsequent interference between the instruments and the femur.

Instructions • Prior to pinning the microblock, adjust it to be in a neutral position

as shown in set-up step 7 of the technique. • When pinning the microblock, orient the middle pin so that it is pointing

toward the head of the femur. • Prior to inserting the medial and lateral fixation pins, ensure A/P offset scale

is at least 3, unless the A/P size of the distal femur is exceptionally small. • Verify that there is approximately 10mm clearance between the femoral

cutting block and the anterior aspect of the femur (Figure 1). • If the femur interferes with the cutting block while setting the resection

angle (Figure 2), a sagittal saw may be used to trim the interfering bone to provide additional travel for the cutting block. Care should be taken not to remove too much bone, which could cause notching or interfere with subsequent sizing.– Alternatively, the microblock may be re-pinned in a more favorable position. In this case registration and

resection angle adjustment steps must be repeated. • If the distal guide contacts the condyles or other instrumentation before reaching the desired resection depth

(Figure 3), the guide may be set at a depth 2 mm or 4 mm greater than the target depth. Pin the cutting block using the +2 mm or +4 mm holes, and shift the cutting block distally after removing the Microblock.– Alternatively, the microblock may be re-pinned in a more favorable position. In this case registration and

resection angle adjustment steps must be repeated.

TeCHnICAL BuLLeTIn

DescriptionDuring hip point registration the software requires that the user maintain a minimum average angular speed in both the A/P and M/L directions. If either speed falls below the allowed limit the registration will be rejected. The display on the navigation unit will indicate the maneuver speeds for each direction (A/P and M/L). More bars indicate higher speed. Green bars indicate sufficient maneuver speed, while red bars indicate insufficient speed.

Instructions • Prior to surgery, practice maneuver on sawbones to develop a feel for a suitable maneuver speed. • If a “Maneuver Too Slow” message is received, increase the speed of the maneuver in the direction

indicated by red bars on the navigation unit display. • A common tendency is to exaggerate the A/P motion when increasing maneuver speed. If only

the M/L direction needs to be accelerated, do not unnecessarily exaggerate the A/P motion. • Take care not to move the pelvis by exaggerating the size of the maneuver when increasing

maneuver speed.

DescriptionDuring hip point registration, the software conducts a check for consistency of the data throughout the maneuver. Inconsistent data triggers a rejection of the registration. This can be caused by movement of the pelvis, inadequate fixation of the microblock to the femur or excessive deceleration when the heel is repositioned at the end of the maneuver.

Instructions • Use at least three headed pins to mount the Microblock to the femur. Ensure the Microblock is

secured with firm, three-point contact to the femur.

• At the end of the hip point maneuver, place the heel down gently.

• Stabilize the pelvis during the maneuver and ensure that the femur is free to move through the full range of motion.

• Remove any retractors or other instruments that could hit the sensor during the hip point maneuver.
