The Chinese Knot Stitch Technique Using a Footprint Ultrasuture Anchor for Rotator Cuff Repair

Management of the rotator cuff presents specific challenges to orthopaedic surgeons. Several locking suture methods have been reported but often fail for a number of reasons. We describe a different technique that is easy to perform and inspired by the Chinese knot, an arthroscopic double-locking suture using a footprint ultrasuture anchor. This technique is similar to the suture-bridge structure on the bursal side of the tendon in that it increases tissue grip and stabilizes initial tendon-to-bone fixation. This technique is especially suitable for the patients who have bursal-side partial-thickness or degenerative small- and medium-sized rotator cuff tears.
