About

1. Purpose :To compare of femoral tunnel placement, tunnel geometry and clinical outcome using two anterior cruciate ligament reconstruction techniques ; transportal technique with flexible reamer and single bundle outside in technique with remnant preservation.

2. Subjects: anterior cruciate ligament (ACL) injury 66 patients

   • Double bundle transportal technique with flexible reamer: 33
   • Single bundle outside in technique with remnant preservation: 33

Full description

Anterior cruciate ligament (ACL) injury patients : Total 66

1. Double bundle transportal technique with flexible reamer: 33

   • Advantage: more normal ACL reconstruction than single bundle technique
   • Disadvantage: to make the two bone tunnel must remove all the residual tissue.

2. Single bundle outside in technique with remnant preservation: 33

   • Advantage: good for being synovium and revascularization. Remained proprioception function helps to functional recovery.
   • Disadvantage: difficult to ensure of visibility and tunnel drilling in the correct position because of remnant tissue.

Enrollment: 67 patients
