AperFix System PCL
Surgical Technique
Note: A posteromedial portal is recommended
to fully debride the posterior tibia for tunnel
positioning, suture management, and graft
passage.
Step 10
Use a curette posteriorly to protect the neurovascular
structures and place the PCL guide parallel to the tibial
plateau. Pass the drill tipped guide wire through the
PCL guide to the posterior tibial cortex (Figure 5).
Note: Use fluoroscopic imaging to confirm proper
pin placement.
Step 11
Using the appropriate size tibial drill, carefully ream
the tibial tunnel.
Note: Fluoroscopic and direct visualization should
be used as guidance.
Graft Preparation
and Tunnel Placement
(cont.)
Step 8
Drill the femoral tunnel first to avoid fluid outflow
through the tibial tunnel.
• With the knee flexed between 90° and 120° (Figure
4), insert a guide wire through the lateral portal to
the center of the PCL footprint (approximately 6-8
mm posterior to the articular surface of the medial
femoral condyle). Create the femoral socket using
the sizing table below:
Femoral Implant Femoral Socket Length
AperFix AM 24 mm 25 mm minimum
AperFix 29 mm 30 mm minimum
Step 9
Flex the knee to 45° and place a transtibial PCL guide
through the medial portal to the PCL insertion location
(approximately 1.5 cm distal to the tibial articular
surface and slightly lateral to midline).
