Fixation strength of biocomposite wedge interference screw in ACL reconstruction: effect of screw length and tunnel/screw ratio. A controlled laboratory study
BACKGROUND Primary stability of the graft is essential in anterior cruciate ligament surgery. An optimal method of fixation should be easy to insert and provide great resistance against pull-out forces.A controlled laboratory study was designed to test the primary stability of ACL tendinous grafts in the tibial tunnel. The correlation between resistance to traction forces and the cross-section ...
متن کاملComparison of Interference Screw and Transcondilar in the Acl Reconstruction
Objective: Femoral fixation in ACL reconstruction with flexor tendon grafts can vary greatly according to the provision of materials and the surgeon’s experience. But studies comparing fixation systems are most often performed on cadavers or animals, without evaluating the clinical results, which affects their comparison with live human patients. This article evaluates the clinical and subjecti...
متن کاملMechanical Aspects of an Interference Screw Placement in ACL Reconstruction
The physical status of an interference screw fixation in an anterior cruciate ligament (ACL) reconstructive surgery is a crucial factor of success. In this study, the insertion of the interference screw into a tibial bone tunnel, and the advancement of the screw between the tendon strands were investigated using both experimental and computer modeling. The mechanical behavior of the bone and so...
متن کاملBiceps tenodesis with interference screw fixation: a biomechanical comparison of screw length and diameter.
PURPOSE To evaluate the effect of screw length and diameter on the mechanical properties of biceps tenodesis (BT) with an interference screw in 2 different locations (proximal and distal). METHODS We randomized 42 fresh-frozen human cadaveric shoulders (mean age, 65 ± 8 years) into 6 groups (n = 7): arthroscopic proximal BT using 7 × 15-, 7 × 25-, 8 × 15-, or 8 × 25-mm interference screws or ...
متن کاملMetallic or bioabsorbable interference screw for graft fixation in anterior cruciate ligament (ACL) reconstruction?
BACKGROUND Approximately 100,000 anterior cruciate ligament (ACL) reconstructions are performed in the USA each year. Interference screw fixation is considered the standard for rigid fixation of the graft and provides higher fixation strength compared with other devices such as staples or buttons. The present study summarizes the latest evidence comparing the effectiveness of the available clas...
