Comparison of tunnel orientation between transtibial and anteromedial portal techniques for anatomic double-bundle anterior cruciate ligament reconstruction using 3-dimensional computed tomography
Arthroscopy. 2013 Feb;29(2):195-204. doi: 10.1016/j.arthro.2012.08.020. Epub 2012 Dec 2450 patients, undergoing anatomic double-bundle anterior cruciate ligament (ACL) reconstruction, were randomized to have the femoral tunnel created using either the transtibial or anteromedial portal technique. Accuracies of the tunnel placement, angle, and length were measured 7 days following reconstruction. The results displayed that the femoral tunnels were positioned deeper, lower, and nearer to the femoral footprint and that the tunnel length was shorter when using the anteromedial portal technique compared to the transtibial technique.
