Reconstruction of the anterior cruciate ligament using the double bundle technique provides better covering of the anatomic insertion site areas and fiber length change behavior. Biomechanical studies and intraoperative measurements with computer navigation systems document increased stability in particular due to rotational stability. To date the impact of the posterolateral bundle is questioned and clinical studies have reported divergent outcomes. ⋯ The sacrifice of hardware ensures easy revisions. The disadvantages are the peripheral tibial fixation, the preparation of the tendons needs tendon length and the creation of tendon knots providing high stability requires practice. The two femoral bone tunnels have proved to be safe regarding the stability of the lateral femoral condyle.
