Arthroscopic Repair of Labrum Using the Inverted V-Shape Double-Strand Vertical Mattress Suture Technique in Hip Joint.

Abstract

The labral suture is essential in the arthroscopic treatment of hip acetabular labral injuries and maintains its suction sealing effect. The traditional single-strand loop fixation, with its loop around the labrum tissue, may cause labral eversion and disrupt the sealing effect. Traditional single-strand vertical mattress suture technique has the advantage of preserving the free edge of the labrum and restoring its suction sealing function. However, for the large labrum tear, the strength of the single-strand suture may be insufficient for stability. At the same time, more anchors will be needed for the procedure, which is one of the key consumables in arthroscopic surgery. Here, we describe an inverted V-shape double-strand vertical mattress suture technique, which preserves the labrum sealing effect by using vertical mattress suture and reduces the number of anchors needed by utilizing a double-strand anchor and the V-shape suture.
