    Nonanatomic tunnel placement is reported in as many as 77% of anterior cruciate ligament reconstruction revision cases.

  • 2

    Mediolateral tibial tunnel placement is difficult because the lateral edge of the native ACL tibial footprint lacks a discrete, consistently identifiable bony landmark.

  • 3

    The study developed Notch-Referenced Mediolateral Verification, using the intercondylar notch as a visual reference to assess and adjust guide-pin position in full knee extension.

  • 4

    This single-institution retrospective study evaluated adults undergoing primary ACL reconstruction with a standardized all-inside, single-bundle technique incorporating NRML verification.

  • 5

    The study compared the tibial tunnel center on postoperative 3D CT with the native tibial footprint center on preoperative 3D MRI to assess mediolateral placement accuracy.
