Summary
This study examined how different tunnel angles and depths in the lateral femoral condyle affect tunnel collision risk during combined ACL and posterolateral corner reconstruction. Results showed that deeper (30 mm) tunnels and larger axial or coronal angles significantly increased collision frequency. Maintaining a neutral coronal alignment, limiting tunnel depth to ≤25 mm, and angling the tunnel anteriorly up to 40° minimized collision risk. These findings provide practical guidelines for safer tunnel placement in ACL reconstruction.
