A comparison of 2 drilling techniques on the femoral tunnel for anterior cruciate ligament reconstruction.

Purpose: This cadaveric study was undertaken to characterize the femoral tunnel geometry resulting from commonly used drilling techniques in anterior cruciate ligament reconstruction.

Methods: We randomized 10 matched-pair cadaveric knees (20 knees) into 2 groups with right and left matched pairs from each cadaver. Of the knees, 10 underwent transtibial femoral tunnel drilling from a far-medial starting point on the tibia (group 1) and 10 had the femoral tunnel drilled from a medial arthroscopic portal (group 2).

A biomechanical comparison of the endobutton cl using transtibial drilling and endobutton direct using anteromedial arthroscopic drilling.

Purpose: To compare the biomechanical properties of the EndoButton Direct (Smith & Nephew, Andover, MA) with the EndoButton CL (Smith & Nephew) using 2 different drilling techniques. Only the femoral side (and not the tibial side) of the graft fixation complex (bone-fixation device-anterior cruciate ligament [ACL] graft) was examined in this study.

Methods: ACL reconstructions were performed on 20 cadaveric knees (10 matched pairs), with an age range from 73 to 89 years, by use of a doubled semitendinosus and gracilis tendon graft.

The effects of extra-articular starting point and transtibial femoral drilling on the intra-articular aperture of the tibial tunnel in ACL reconstruction.

Background: The recent emphasis on more horizontal femoral tunnel placement for single-bundle anterior cruciate ligament (ACL) reconstructions requires placing a femoral tunnel lower on the lateral wall of the notch. Some surgeons have advocated moving the starting point of the tibial tunnel farther medial to achieve this more horizontal tunnel.

Purpose: To compare tibial tunnel aperture changes with transtibial femoral tunnel drilling.
