Three-Dimensional Imaging Validation of a Notch-Based Method for Assessing Mediolateral Tibial Tunnel Placement in Anterior Cruciate Ligament Reconstruction
To assess whether Notch-Referenced Mediolateral (NRML) verification accurately positions the tibial tunnel center relative to the patient-specific native ACL tibial footprint center.
Approach:
Design and participants: Single-institution retrospective cross-sectional study of adults undergoing primary ACL reconstruction with a standardized all-inside, single-bundle technique and NRML verification from January 2024 through December 2025.
Imaging comparison: Compared the tibial tunnel center on postoperative 3D CT with the native tibial footprint center measured on preoperative 3D MRI.
Sample size: The planned sample size was approximately 62, based on a one-sample precision calculation.
Key Findings:
The provided context describes the study rationale, objective, and methods but does not report participant numbers, measurement results, or statistical findings.
Interpretation:
The study was designed to validate an intraoperative notch-based visual reference for mediolateral tibial tunnel placement using patient-specific 3D imaging.
Limitations:
The supplied context ends during the surgical technique description and does not include study results or the full methods.
The study was retrospective, cross-sectional, and conducted at a single institution.
