Description
Augustin and colleagues present in 2026, as conference poster 74, a cadaver anatomy study of three stabilizing structures on the outer knee. It is meant to guide where surgeons drill graft tunnels in lateral knee reconstruction. Fixation placed wrong for how a ligament behaves in bending will fail.
Dissected knees were digitized at six flexion angles from straight to ninety degrees. The fibular collateral ligament's thigh attachment sat more forward and lower than the anterolateral ligament's, and the two ligaments anchor at clearly different spots below the joint as well. Both ligaments shortened significantly as the knee bent. The collateral shortened by about seven and a half millimeters and the anterolateral by about six and a half across the arc. The iliotibial band fibers, by contrast, barely changed length, a difference the authors say should individualize tunnel placement.
