The normal anterior cruciate ligament (ACL) can be divided into two bundles, anteromedial (AM) and posterolateral (PL). Each bundle appears to function at different angles of flexion of the knee. Together, they are responsible for the stability of the joint. Reconstruction of the ACL, using multistranded hamstring tendons, has concentrated mainly on replacement of the AM bundle (single-bundle reconstruction). Recent progress in the technique and instrumentation of arthroscopic knee surgery has allowed reconstruction of the two bundles separately to mimic more closely the normal structure of the ACL using hamstring tendons. Although some authors have reported good results using a double-bundle technique, few have investigated whether both reconstructed bundles have functional partial responsibility for the stability of the joint at different angles of flexion of the knee. Due to the relative novelty of this subject matter, the anatomical and biomechanical aspects of the ACL, as well as the arthroscopic DB techniques shall be reviewed, the study has to review all available literature for comparison parameters. Comparison parameters will include the International Knee Documentation Committee (IKDC) evaluation, Lysholm test, KT1000 arthrometer differences, anterior translation, Lachmann test, and anterior drawer test. Additional parameters will include knee motion, muscle torque, the pivot shift examination and KT-2000 results. The comparison will also include all available data on proprioception measurement. Thigh muscle strength analysis data will also be reviewed for both techniques, as well as joint rotatory stability will be compared when possible.
