Femoral Tunnel Position on Conventional MRI After Anterior Cruciate Ligament Reconstruction-Transtibial Technique Versus Transportal Technique

January 19, 2012 updated by: Jung Ho Noh, National Police Hospital
The position of the femoral tunnel in anterior cruciate ligament (ACL) reconstruction has been assessed on three dimensional CT (3D-CT) scan or in cadaveric study. However, these methods have some issues; 3D-CT scan has a concern on radiation exposure and cadaveric study is not easily available nor an in vivo test. The purpose of this study is to compare the position of the femoral tunnel aperture on conventional MRI and the outcomes after single bundle ACL reconstruction using free tendon Achilles allograft between transportal technique and transtibial technique in active young men.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: transtibial technique
In anterior cruciate ligament reconstruction, femoral tunnel was made via tibial tunnel.
Femoral tunnel was made via tibial tunnel in anterior cruciate ligament reconstruction.
femoral and tibial tunneling graft fixation on the femoral side with endobutton and on the tibial side with post-tie and interference screw
Active Comparator: Transportal technique
In anterior cruciate ligament reconstruction, femoral tunnel was made via anteromedial portal.
femoral and tibial tunneling graft fixation on the femoral side with endobutton and on the tibial side with post-tie and interference screw
Femoral tunnel was made via anteromedial portal in anterior cruciate ligament reconstruction.
Other Names:
  • anteromedial portal technique

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Lysholm score
Time Frame: at least two years after surgery
Lysholm score was superior in transportal technique to transtibial technique.
at least two years after surgery
Position of femoral tunnel aperture
Time Frame: within one week after surgery
The position of the femoral tunnel aperture with transportal technique was more posterior than that of transtibial technique.
within one week after surgery
