Comparative Study of the Inclination Angle and Complications of Eccentric Grafts Position in ACL Reconstruction and Normal ACL: Retrospective Cohort

Not Applicable

Completed

• Conditions: Anterior Cruciate Ligament Injuries
• Interventions: Procedure: Interference screw

• Registration Number: NCT04188704
• Lead Sponsor: Ramathibodi Hospital

Brief Summary

The anatomic ACL reconstruction aims at functional restoration of the ACL to its native dimensions, collagen orientation and insertion sites. Even if the anatomic foot prints are correctly chosen for the tibial and femoral tunnels does the position of interference screw in the tibial tunnel alter the ACL orientation? The study hypothesized that the position of interference screw in the tibial tunnel would alter the graft orientation in anatomic ACL reconstruction. The purpose of this study was to compare graft orientation and inclination angle with posterolateral and anteromedial interference screw position in tibial tunnel in aperture fixation techniques.
