3. Size 2, Medial Pivot
Lateral Medial
• Tibial Cut 3.0° posterior slope
• Resection side:
2 mm from lowest side
• Insert AP orientation:
Medial Tubercle
• Medial resection: 4.4 mm
• Lateral resection: 2.0 mm
Femoral Alignment Method
• Distal cut is referenced to Mechanical Axis - 0 degree
• Femoral rotation set by the 3 degree external to posterior condyles
• Distal resection level set to 9.0 mm
• AP component position set by Anterior flange placed to prevent notch/overhang
• Femoral component flexed 3.0° from the Mechanical axis in order to obtain optimal
posterior resections
• Size 2R ADVANCE® Standard Femur
Tibial Alignment Method
• Proximal cut 3.0° posterior slope to Mechanical Axis - 0 degree
• Component rotation set by Medial Tubercle
• Resection level 2 mm from lowest side
• ADVANCE® Tibia Base Size 2
• Size 2 Right 10 mm Medial Pivot Insert

Engineer Comments
The patient's pre-operative alignment is 10.2° valgus, therefore special attention to ligament
balancing may be necessary. The tibial compartment points are inverted from normal anatomy -
the medial compartment point is higher than the lateral compartment point.
Recommended Implants
• Femoral component: KFTCNP2R
• Tibial base: KTCCNP20
• Insert: KIMP210R
• Part Number:
• Order Kit: K100KT80 and K100KT3R

Tibial alignment
Images below show the 1.3 degree varus adjustment to the tibia resection as requested
by the Surgeon. The adjustment to the Tibia is shown by the solid Cyan line; the dotted
Cyan line represents the Tibial Mechanical Axis according to Prophecy‘s ® protocol.
