CORR Insights^®: Does Anteromedial Portal Drilling Improve Footprint Placement in Anterior Cruciate Ligament Reconstruction?

Excerpt

The current study by Arno and colleagues compares the footprint coverage of anteromedial portal and modified transtibial ACL reconstruction, and its influence on validated outcomes scores and objective measurements of knee stability. The study confirms the current knowledge that transtibially drilled femoral tunnels are more vertical compared to both the native ACL and bone tunnels drilled through an anteromedial portal. Interestingly, the tibial bone tunnels are located posterior and medial to the native ACL in both groups. This finding is consistent with previous studies for the transtibial group [2, 5], but not for independently drilled tunnels. However, at short-term followup, the study groups were comparable in terms of knee stability and patient-reported outcomes. …
