Editorial Commentary: The Value of Retensioning and Knot Tying

Abstract

This basic science study evaluated the effects of retensioning and knot tying on the biomechanical properties of an adjustable-loop anterior cruciate ligament reconstruction device compared with a closed-loop device. The authors of a study in this issue compared various loading conditions to reveal that retensioning and knot tying combine to make both the closed-loop device and the newer adjustable-loop device clinically equal with regard to cyclic elongation.
