The Longitude-Latitude-Loop Used for Complex Bankart Lesion Repair: An All-Arthroscopic Technique

ABSTRACT: The most frequent operation for anterior shoulder instability is the arthroscopic Bankart repair, which has a positive outcome and a low rate of complications. A variety of restoration procedures have been reported to reconstruct labral height and reproduce a dynamic concavity–compression reaction. The longitude–latitude loop is a knotless high-strength suture method that simultaneously tightens the joint capsule in the warp and weft direction and resists tearing. The suture method is safe and reproducible. This study aimed to present a longitude–latitude loop suture for joint capsule labral complex repair during Bankart arthroscopy surgery. Technique Video Video 1 The longitude–latitude loop used for complex Bankart lesion repair. This is a right shoulder and the visualization starts in the posterior portal. Properly investigate the pathologic Bankart lesion. Thoroughly freshen the cartilage of the articular glenoid rim and the lateral bone bed of the articular glenoid. The area of injury is completely released to the medial subscapularis muscle belly with the rasp, and the glenoid labrum is loosened and floated off the articular surface. A lark’s head knot is constructed on the capsule–labrum complex tendon with a No. 2 FiberWire suture. One suture strand exits through the tissue where the labrum and glenoid tear. Create the longitude–latitude loop at 5:20-4:30, 4:20-3:30, and 3:20-2:20 o’clock and use different-colored FiberWire threads to separate multiple loops. According to the location of the longitude–latitude loop, drill a 2.9-mm hole 1 mm inside the 5:30-o’clock joint margin. FiberWire strands of the longitude–latitude loop are passed through the PushLock 2.9-mm anchors while the other FiberWires of each group are placed outside the anterior portal and the glenoid labrum of the joint capsule is lifted and repositioned. Tighten the upper end and the lower end in turn and tighten the screws, pushing up the glenoid labrum tissue to form the Bump. Fix all the longitude–latitude loops with 2.9-mm anchors, then cut off the residual suture, and a novel, self-locking, and high-resistant loop configuration is constructed.
