Objective: Anatomic reconstruction of anterior cruciate ligament is becoming more important as the knee anatomy and biomechanics are being understood much more. In order to place femoral tunnel at its original point, it should be drilled from another porta which is more medial instead of from tibial tunnel. In this article we aimed to present clinical and radiologic results of ACL reconstructions that we placed femoral tunnel from a third anteromedial portal.
Material and methods: The study included 43 patients (four female, 39 males; mean age 29.3 years; range 18 to 42) with ACL injury. ACL reconstruction was performed to all of the patients with the three portal anatomic single bundle technique using hamstring autograft. Preoperative and postoperative clinical evaluation was done by Lysholm knee score, Tegner activity score, International Knee Documentation Committee (IKDC) score. Anteroposterior instability evaluation was done by anterior drawer and pivot shift tests.
Results: According to IKDC score, preoperatively 22 patients were D (51%) and 21 were C (49%) and postoperatively 33 were A (%76), 10 were B (%23) and 1 was C (%2). Preoperative mean Lysholm knee score was 54,87 (45-66) and increased to 89,86 (59-99) at the last control. Tegner activity score was 4,70 preoperatively and 5,22 postoperatively.
Conclusion: In ACL reconstruction, restoring knee biomechanics is possible by placing graft near normal anatomy. As defined for this purpose, three portal technique can place tibial and femoral tunnel as anatomic as possible. This technique is an applicable technique with good results.
