Comparison of clinical results, second look arthroscopic findings, and magnetic resonance imaging findings, between the transportal and outside-in techniques after double bundle anatomic anterior cruciate ligament reconstruction: A prospective randomized controlled trial with a minimum 2-year follow-up

Although image analysis has shown that the outside-in (OI) technique is associated with different femoral tunnel geometry than the transportal (TP) technique in anatomic anterior cruciate ligament (ACL) reconstruction, it is not known whether clinical results differ between the two techniques. We aimed to compare clinical results, second-look arthroscopic findings, and magnetic resonance imaging (MRI) findings between the TP and OI techniques in anatomic double-bundle (DB) ACL reconstruction.
