Arthroscopic transosseous rotator cuff repair: the eight-shape technique.

All-arthroscopic anchorless transosseous suture techniques combine the advantages of the open transosseous repair with the benefits of arthroscopic technique. However, all the techniques described until now are very complex, difficult to reproduce and associated with an increased surgical time. The authors developed a novel all-arthroscopic anchorless transosseous suture technique easy to perform and to reproduce. This procedure maximizes the tendon-footprint contact area obtaining both medial and lateral fixation without using any device, employing only 1 suture tape so to avoiding the risk of suture twist. The preparation of two transosseous tunnels is very easily and safely performed thanks to a dedicated instrument. The procedure is described in details. Moreover, the preliminary favorable results after a minimum follow-up of 12 months are reported.
