Biomechanical Comparison of Interference Screws and Combination Screw and Sheath Devices for Soft Tissue Anterior Cruciate Ligament Reconstruction on the Tibial Side
The tibial fixation site has been reported to be the weakest point in anterior cruciate ligament (ACL) reconstructions. Numerous interference screws and combination screw and sheath devices are available for soft tissue fixation, and a biomechanical comparison of these devices is necessary. This study hypothesiszed that combined screw and sheath devices would provide superior soft tissue fixation properties compared with interference screws in a porcine model.

has specialized skills and expertise in diagnosing and treating complicated knee injuries. He has treated athletes at all levels, including Olympic, professional and intercollegiate athletes, and has returned numerous athletes back to full participation after surgeries. Recognized globally for his outstanding and efficient surgical skills and dedication to sports medicine, he has received many research awards, including the OREF Clinic Research Award considered by many a Nobel Prize in orthopedics. Dr. LaPrade is one of the most published investigators
in his field, and many of the surgeries that he has developed are now performed worldwide and recognized as the “gold standard” for the treatment of complex knee injuries.
