Summary
Optimal anatomical tunnel can be achieved by our modified Trans-tibial Technique of ACL reconstruction with BTB graft.
Abstract
Background
The importance of creating an anatomic anterior cruciate ligament (ACL) reconstruction has been receiving significant attention. The best technique by which to achieve this anatomic reconstruction continues to be debated. The two most common methods are the transtibial (TT) and anteromedial (AM) techniques. In the transition from isometric to anatomical ACL reconstruction, transportal technique of ACL reconstruction has become the widely used method. In our clinical practice, we found that, anatomical femoral tunnel can be created in modified transtibial technique.
Questions/Purposes
In this prospective comparative study, we by accurately placing the tibial tunnel and by using a flexible reamer, guide wire for creating femoral tunnel. Against disadvantages of trnasportal technique like posterior wall breakage, short tunnel length, difficult visualisation in hyperflexion and revision rates. By adopting a modified transtibial approach for ACL reconstruction with BTB graft, the study intends to analyze the accuracy of the femoral tunnel with CT and Radiograph data.
Methods
30 patients who underwent single bundle ACL reconstruction with BTB graft using modified transtibial technique in single centre were chosen and CT and radiographs was taken for postoperative analysis. Femoral tunnel angulation was calculated with help of AP radiographs and centre of femoral tunnel with CT using quadrant method.
Results
Evaluation of the position of the femoral tunnel aperture by the quadrant method using CT. The coordinates of the standard area of the ACL femoral footprint center were 31+/- 5% of the distance parallel to the Blumensaat line measured from the posterior border and 40.9+/-5% of the distance perpendicular to the Blumensaat line measured from the Blumensaat line. Femoral tunnel measured approximately 52+/-5 degree on AP plain radiographs.
Conclusion
Optimal anatomical tunnel can be achieved by our modified Trans-tibial Technique of ACL reconstruction with BTB graft..
