Conditions

Anterior Cruciate Ligament Rupture

Brief summary

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.

Interventions

PROCEDUREtranstibial technique

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

PROCEDURETransportal technique

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

PROCEDUREanterior 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

Design outcomes

Primary

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