Assessment of fixation for anterior cruciate ligament reconstruction using oversized suspensory devices on full-length femoral tunnels

摘要

Background: In ACL repair, full-length single-diameter tunnels facilitate anatomic femoral fixation with suspensory devices, especially with outside-in techniques, and are required after accidental cortical perforation. With tunnel diameters over 6 mm, fixation resistance using regular suspensory devices may not suffice. Oversized cortical footprint devices could be a solution to guarantee fixation performance in larger tunnel diameters. This study aims to assess the biomechanical properties of ACL femoral fixation provided by two enlarged suspensory devices of similar characteristics, a fixed loop (G-Lok (TM) with G-Lok-XL (TM)) and an adjustable loop (ProCinch (TM) with G-Lok-XL (TM)), resting on a full-length 9 mm diameter tunnel compared to the widely accepted regular fixed-loop device (G-Lok (TM)) on a socket tunnel.
