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

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.

Inclusion criteria

  • diagnosis of anterior cruciate ligament rupture

Exclusion criteria

  • female
  • over 45 years old
  • the subjects who had ACL reconstruction with graft other than Achilles allograft
  • the subjects who had concomitant other ligament injuries on the same knee needing surgical treatment
  • revision ACL reconstruction
  • double bundle ACL reconstruction
  • concomitant full thickness cartilage injury needing cartilage repairing surgery

Treatment and study plan

transtibial technique

Procedure

Femoral tunnel was made via tibial tunnel in anterior cruciate ligament reconstruction.

Transportal technique

Procedure

Femoral tunnel was made via anteromedial portal in anterior cruciate ligament reconstruction.

Other names: anteromedial portal technique

anterior cruciate ligament reconstruction

Procedure

femoral and tibial tunneling graft fixation on the femoral side with endobutton and on the tibial side with post-tie and interference screw

Primary outcomes

  1. Lysholm score

    Time frame: at least two years after surgery

    Lysholm score was superior in transportal technique to transtibial technique.

  2. 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.
