Arthroscopic double-pulley remplissage technique for engaging Hill-Sachs lesions in anterior shoulder instability repairs.

We present a modified arthroscopic technique used to treat anterior shoulder instability associated with mild glenoid bone loss and a large Hill-Sachs lesion. The procedure aims to convert a bony intra-articular defect into an extra-articular defect by insetting the infraspinatus into the Hill-Sachs lesion. The arthroscopic procedure is performed with the patient in the lateral decubitus position, and the same portals used for anterior instability repair are used for this technique. The sequence of steps involves placing and passing the glenoid anchors and sutures and then waiting to tie the anterior sutures until after the humeral suture anchors have been placed. The subacromial bursa is cleared; then 2 transtendon suture anchors are placed in the Hill-Sachs lesion. Next, the previously placed Bankart repair sutures are tied, and finally, the remplissage sutures are tied in the subacromial space over the infraspinatus by use of the transtendon double-pulley technique. This technique uses the eyelets of the 2 suture anchors as pulleys and creates a double-mattress suture.
