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.

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

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