Anterior cruciate ligament reconstruction creating the femoral tunnel through the anteromedial portal. Surgical technique

The anterior cruciate ligament reconstruction is a common procedure that improves stability and function of the knee. The surgical technique continues to evolve and many issues are still under debate. These mainly include: (1) graft selection (patellar tendon, hamstring, quadriceps tendon, or allografts), (2) surgical technique (double versus single bundle), and (3) femoral tunnel drilling. Currently, the most controversial one is the femoral tunnel drilling (transtibial vs. anteromedial portal drilling). Common opinion is that drilling the femoral tunnel through the anteromedial (AM) allows a more anatomic placement of the graft and a better rotational stability; therefore, this technique is gaining in popularity compared with the transtibial drilling despite a greater difficulty and the risk of medial condyle damage, tunnel back wall blowout, and inadequate socket length. The aim of this article is to describe the surgical technique of the anterior cruciate ligament reconstruction (single and double bundle), drilling the femoral tunnel through the AM portal.
