AperFix System PCL
Surgical Technique
Step 2
Whip stitch approximately 20 mm of the graft ends
with a sturdy suture (#2 non-absorbable) in the
standard fashion.
• It is recommended to use two different colored
sutures to distinguish between the graft bundles.
Step 3
Double the graft over at its mid length, then pull
the graft bundles through the Graft Sizing Block to
determine the diameter of the implant to be used.
Select a diameter which the graft bundle passes tightly
through. Please refer to the sizing table above.
Step 4
Pass the prepared soft tissue grafts through the
eyelets of the AperFix Femoral Implant (AperFix 29
mm shown) (Figure 1).
Note: Taper graft ends for easier graft loading
through the implant.
Posterior Cruciate Ligament Review
Primary restraint to posterior tibial translation:
• Larger anterolateral (AL) bundle tight in 90° flexion
• Posteromedial (PM) bundle tight in extension
Origin:
• Femur: 8-10 mm posterior to the anterior articular
surface of the medial femoral condyle
• Tibia: 15 mm distal to the posterior tibial plateau
Graft Preparation
and Tunnel Placement
Step 1
The recommended graft choice is an anterior or
posterior allograft tendon at least 240 mm in length
(when doubled over, graft should ideally fit an 11 mm
implant to maximally fill the PCL footprint). Split the
graft longitudinally to half of its length (pant leg).
Note: Autograft hamstring tendon may also be
used.
