Preoperative Planning
• Assess bone stock and potential ligament instability and
the anatomical axis with 36" long standing A/P X-rays.
• Measure valgus angle (angle between anatomic and
mechanical axis) to assure the distal femoral cut is
perpendicular to the mechanical axis (Figure 1).
• Estimate femoral component size using lateral
view X-ray.
Note: Confirmation of the appropriate size component
intraoperatively is critical for normal kinematics.
Incision
• The Vanguard XP Total Knee Instrumentation is
designed for a standard surgical technique (Figure 2).
• Release the patella tendon to create space on the
lateral side of the tibia. Ensure that the patella tendon
tibia interface is released so the patella can easily sit in
the lateral gutter of the knee.
Note: If multiple scars from previous surgeries exist,
evaluate skin incision placement and elements of
scarring which may decrease soft tissue mobility.
