A biomechanical evaluation of the iliotibial tract screw tenodesis.

Abstract

Biomechanical testing of the iliotibial tract screw tenodesis was performed in 10 cadaveric knees under forces approximating in vivo conditions. Force versus displacement curves at various flexion angles were generated with the anterior cruciate ligament intact, with the anterior cruciate ligament sectioned, and after the iliotibial tract screw tenodesis had been performed. Displacement force was measured to 5, 10, and 15 mm. The iliotibial tract screw tenodesis was ineffective in reducing anterior translation of the tibia in the anterior cruciate ligament-deficient knee at forces approximating in vivo conditions.
