In this detailed surgical walkthrough, we explore the full technique behind single‑portal posterior labral repair using Knotless FiberTak® soft anchors. This method offers a streamlined and efficient approach for stabilizing posterior labrum tears, while improving anchor trajectory, suture control, and capsulolabral tensioning.
The surgeon begins by positioning the patient in a beach‑chair setup, ensuring optimal access to the posterior shoulder. A key point emphasized throughout the video is the importance of portal placement: a slightly more superior and lateral posterior portal creates an ideal working angle, often close to 45°, for accessing the posterior glenoid.
Once inside the joint, the displaced posterior labrum is identified and probed from the anterior portal. The enhanced working angle through the posterior cannula allows for accurate anchor trajectory and improved visualization. One of the most valuable pearls in this technique is the decision to pass the suture lasso first, which prevents suture tangling—one of the most common challenges during single‑portal shoulder arthroscopy. Using a 90° lasso, the surgeon passes beneath the capsulolabral junction at the articular margin. The lasso is then retrieved superiorly through the cannula, ensuring clean, untangled suture flow.
Next, anchor placement begins using either a straight or curved drill guide depending on orientation. With the improved superior‑lateral portal trajectory, the surgeon gains a perfect angle onto the posterior glenoid face. After the drill reaches its hard stop, the Knotless FiberTak® anchor is inserted, its sutures separated, and the anchor firmly seated. The repair stitch is shuttled through the previously placed lasso without twisting—another major benefit of the lasso‑first approach.
A key highlight of this procedure is its ability to tension the posterior band of the inferior glenohumeral ligament in a controlled, predictable manner. Because the anchors are placed 2 mm apart directly onto the glenoid face, the technique creates a strong, low‑profile posterior bumper that improves joint stability. The small‑diameter all‑suture anchors allow the surgeon to position multiple fixation points with minimal cartilage disruption. This results in a highly anatomical repair with improved tissue adaptation and restoration of the native capsulolabral contour.
The video concludes by demonstrating the final construct: five Knotless FiberTak® anchors precisely placed up the posterior glenoid, all passed using the lasso‑first technique to avoid tangling and ensure smooth tensioning. The final repair shows excellent bumper formation and a secure, anatomically restored labrum. Surgeons seeking a more efficient and predictable method for treating posterior shoulder instability will find this technique both accessible and reproducible.
