The DMD Knot: A New Locking, Flip Knot

To perform an arthroscopic rotator cuff or labral tear, surgeons need to know how to tie athroscopic knots. The ideal knot should be able to withstand large biomechanical loads while being easy to tie. With numerous knot configuration options available to surgeons, many recent studies have assessed the biomechanical characteristics of some of the more commonly used knots. Different studies have referred to the flip knot used by the senior author (DMD) as the ‘‘Dines knot,’’ and in many of these studies, it has exhibited the best loop security, resistance to sliding, distance to failure, knot security, knot weight, and resistance to reverse slippage. To date, there is no published technique note on how to tie the Dines knot, which is referred to in this note as the ‘‘DMD knot.’’ (Journal of Surgical Orthopaedic  Advances 17(2):115–118, 2008)
