The use of arthroscopic repair of rotator cuff tears continues to increase with improved surgical experience and instrumentation. However, it is widely accepted that the weakest aspect of the repair construct remains the tissue-suture interface [1, 2]. Critical to the repair is having high initial fixation strength to allow minimal gap formation and mechanical stability until healing occurs [3, 4]. This emphasizes the need to identify new suture techniques to improve the strength of repairs, open or arthroscopic, in an attempt to improve the rates of healing.
