Quadrupled Semitendinosus ACL Reconstruction Combining Cortical Button in Femur and Interference Screw in Tibia

摘要

Anterior cruciate ligament (ACL) reconstruction with hamstring tendons has gained popularity in the past and is the most used type of graft in several national registries. It usually involves the harvest of both gracilis and semitendinosus tendons from the ipsilateral knee. More recently, the use of only 1 of the tendons (semitendinosus) in a tripled or quadrupled arrangement has been described, especially in an all-inside type of reconstruction. Having a thicker tendon with a quadrupled semitendinosus (ST), instead of double gracilis and ST enables to a have a graft with enough diameter to resemble more closely the native ACL and decreases the risk of graft rerupture. This Technical Note aims to present a way of reconstructing the ACL using a quadrupled ST graft, with suspensory cortical button in femur and interference screw in tibia, as an alternative to the all-inside technique.
