A biomechanical comparison of initial soft tissue tibial fixation devices: the Intrafix versus a tapered 35-mm bioabsorbable interference screw.


BACKGROUND Biomechanical testing of the Intrafix device has not been performed using human tibiae. HYPOTHESIS The Intrafix device would provide comparable or superior tibial fixation of a quadrupled hamstring tendon graft to a 35-mm-long bioabsorbable interference screw. STUDY DESIGN In vitro, biomechanical study. METHODS Eight paired human tibiae and… (More)
