We established a technique for femoral tunnel preparation through direct vision of the femoral footprint with maximum preservation to the native anterior cruciate ligament (ACL) remnant using a posterior trans-septal portal. Anterior arthroscopy is difficult for the proper tunnel placement without sacrificing the ACL remnant. Posterior arthroscopy could be helpful for viewing the posterior insertion of the ACL remnant that provides excellent femoral footprint exposure without sacrificing the native ACL remnant. Therefore, a posterolateral portal technique using a 70° arthroscope through a posterolateral portal is introduced. However, using the 70° arthroscope, an oblique view is displayed and distorted view could be seen. Therefore, to achieve the goal of posterior arthroscopy and avoid obstacles of the posterolateral view with the 70° arthroscope, we introduce this technique that uses the posterior trans-septal portal with a 30° arthroscope that provides an excellent viewing to the femoral footprint through a hole of the posterior septum.
