Double tibial tunnels 'supra' over-the-top anterior cruciate ligament reconstruction with lower initial graft tension achieves comparable anterior stability to single-tunnel: A cadaveric study using a robotic simulator.

ABSTRACT:

Purpose

To compare the anterior tibial translation (ATT) between single-bundle (SB) and double-bundle (DB) 'supra'-over-the-top anterior cruciate ligament reconstruction (s-OTT ACLR) during the anterior drawer test in a cadaveric model.

Methods

This was a controlled laboratory study. Seven fresh-frozen cadaveric knee specimens and a robotic testing system were used. Initially, the same testing procedure (100 N anterior drawer load applied at 0°, 15°, 30°, 60° and 90° of knee flexion) was applied to the following four different knee conditions: intact, anterior cruciate ligament (ACL)-sectioned, SB s-OTT ACLR and DB s-OTT ACLR knees. Subsequently, a combined load of 5 Nm internal tibial torque and 10 Nm valgus torque was applied at 15° and 30° of knee flexion as a simulated p
