The pullout strength and use of tibial interference screws during endoscopic ACL reconstruction surgery.

This article retrospectively reviews the last 89 ACL reconstructions done over the past 24 months by the senior author and also investigates the pullout strength of a 15-mm long interference screw in cadaveric knees. Results revealed that interference screw fixation at the tibial tunnel during endoscopic ACL reconstruction should almost always be possible by ensuring a tibial tunnel with adequate length, taking additional bone on the graft from the proximal tibia, twisting the graft, and possibly using a 15-mm interference screw.
