Arthroscopic Bankart repair in the beachchair position: a cannulaless method using an intra-articular suture relay technique.

In shoulder arthroscopy, cannulas with large diameters (7-9 mm) are commonly used both in the lateral decubitus and the beachchair position because they ensure the easy introduction of instruments into the intra-articular space and provide a clear arthroscopic view through the application of high intra-articular pressure. On the other hand, fluid extravasation and the resulting inconvenience due to the narrowing of the intra-articular working space are also obvious issues. Consequently, this makes arthroscopic stabilization surgery all the more challenging. To avoid these shortcomings of this procedure, we believe cannulas should be used only when necessary such as for knot tying and for transtendon portals. In this article, we report a unique and original method of arthroscopic Bankart repair in the beachchair position with limited use of cannulas of smaller diameter (5 mm) and its advantages over ordinary arthroscopic techniques using large-diameter cannulas in terms of preventing fluid extravasation and keeping a wide working space, which facilitates beneficial intra-articular techniques.
