Lateral Ankle Ligament Repair

!!
In a curvilinear fashion, carefully detach the anterior and distal ATFL and calcaneal fibular
ligament (CFL) directly from the distal fibula as a full thickness flap (A). Care must be taken to
not damage the peroneal tendons along the most distal portion of the fibula, as the CFL is the
“floor” of the peroneal tendon sheath. Avoid plunging with the scalpel blade as the talar
articular cartilage is immediately deep to dissection. Inspect the lateral talar dome for any
osteochondral pathology. Carefully peel the fibular periosteum off of the anterior and distal
fibula (B). Using a burr or rongeur, decorticate the anterior and inferior border of the distal
fibula to create a bleeding bone trough (C).

Using a 3.5 mm Drill Bit and Drill Guide (found in the Morphix Procedure Pack), drill two to
three tunnels on the anterior and inferior border of the distal fibula. Drill until the hard stop on
the Drill Bit reaches the back of the Drill Guide to achieve appropriate tunnel depth (A). Ensure
that the bone tunnels do not converge or enter the ankle joint (B).
