knee dislocation

Background

Multi-ligament knee injury (MLKI)

- 2 or more ligaments disrupted

Knee dislocation

- ACL + PCL + one of collaterals

High energy (MVA)

Low energy (sport)

- low energy has 5% arterial injury

Avoiding convergence of ACL tunnel and femoral tunnels of popliteus / LCL

- drill LCL and popliteus femoral tunnels anterior to avoid more posterior ACL tunnel

- avoid drilling LCL femoral tunnel proximal, to avoid more proximal ACL tunnel

Moatshe et al. Am J Sports Med 2017

- avoiding tunnel convergence

- aim LCL and popliteus tunnel anteriorly 35^o
