Arthroscopic Repair of Type II SLAP Tears Using Suture Anchor Technique.

ABSTRACT: Arthroscopic SLAP tear repair has become an increasingly used treatment for patients presenting with symptomatic SLAP tears after failed nonoperative management. Debridement, SLAP repair, and open or arthroscopic biceps tenodesis or tenotomy have been used for the treatment of SLAP tears. Various techniques for repair have been described, and furthermore, there is a high incidence of concomitant pathology of the shoulder. Repair remains an excellent option in isolated SLAP tears amenable to repair, with excellent outcomes in well-indicated patients. We present a method for repairing a SLAP tear using standard suture anchor fixation, anterior and posterior portals, and an accessory portal of Wilmington. Adequate labral repair can be achieved with this technique in patients with no concomitant biceps pathology. This report highlights this technique for SLAP repair in patients with isolated symptomatic SLAP tears that have failed conservative management.

Project description:Meniscus root tears are increasingly being recognized and treated because of improved awareness and diagnostics. These injuries commonly occur in combination with knee ligament injuries. Untreated posterior meniscus root teats have been demonstrated to increase contact pressure and decrease contact area, ultimately leading to unfavorable joint loading and development of early osteoarthritis. Posterior lateral meniscus root tears (PLMRTs) also have been reported to increase anterior tibial translation and pivot shift in anterior cruciate ligament–deficient knees. Therefore, it is crucial to repair meniscal root tears when possible to restore knee joint loading and kinematics. Several techniques for repair of the PLMRT have been described. In this Technical Note, we describe our preferred technique for repair of PLMRT using an all-suture anchor. This technique is reproducible, does not need a tunnel, mitigates bungee effect of transtibial technique, and the anchor can easily be inserted on the footprint without a need for a guide. Technique Video Video 1 We present our arthroscopic repair of posterior root tears of the lateral meniscus with all-suture anchor. The surgical procedure is performed with the patient under epidural anesthesia in the supine position. A padded, nonsterile tourniquet is placed high on the operative thigh, and the patient is positioned with lateral support at the level of the tourniquet and a foot post to allow the knee to be maintained at 90° of flexion when required. The operative leg is prepared and draped in standard fashion. Standard anterolateral and anteromedial portals are created for routine diagnostic arthroscopy. The torn meniscal root should be probed to assess for severity and tear pattern. First with a burr and then with a curved curette, the tibial attachment site of the torn lateral meniscus root is debrided of soft tissues and overlying cartilage down to a bleeding bone bed to improve healing of the repair. Appropriate knee flexion is key to achieve a correct anchor placement. Therefore, an accessory high anteromedial portal is created with the knee hyperflexed. A curved guide is inserted through the high anteromedial portal and the guide is placed at the prepared insertion site of the footprint. A pilot hole is created at an appropriate angle using a 1.8-mm flexible drill. Afterwards, a 1.8 mm all-suture anchor loaded with a FiberWire no. 2 is placed. We recommend to set the anchor and test its stability by pulling on the sutures. The leg is then brought into the figure-of-4 position. The sutures are retrieved through the standard anteromedial portal. A direct suture passer and retriever is loaded into the bottom jaw, and it is then introduced through the standard anteromedial portal. Once the suture passer and retriever has been positioned at the desired location on the meniscus, the top jaw is closed and the back trigger is squeezed to advance suture through the tissue bottom up. With the suture captured in the top jaw, the Knee Scorpion is retracted from the tissue. The same procedure is then repeated in the posterior part of the meniscus with the second, free-end of the suture. A simple arthroscopic knot is then tightened under direct arthroscopic visualization aiming for the correct amount of tension. Finally, with a FiberTape Cutter, the FiberWire is cut and the strength of the suture fixation is tested with a probe.

Project description:For overhead athletes and, in particular, baseball pitchers, the rates of success and return to play for those who have undergone arthroscopic repair of type II SLAP lesions are poor, ranging from 7% to 62%. The reasons for the poor results and high failure rates in overhead athletes with type II SLAP repairs are multifactorial and are a combination of many factors. These factors include the failure to establish the diagnosis and treat these athletes preoperatively; the inability of the operating surgeon to differentiate normal anatomic variants from pathologic SLAP lesions at the time of surgery; the surgical technique, which may violate the rotator cuff; or the placement of suture anchors, which restricts external rotation and alters overhead throwing mechanics. The proper diagnosis of SLAP lesions can be difficult because SLAP tears rarely occur in isolation and are often associated with other shoulder pathology. A proper history detailing the onset of symptoms and whether there was an acute episode of trauma or a history of repetitive use is critical. It is important to remember that no single physical examination finding is pathognomonic for SLAP tears. When seen in isolation, SLAP tears may mimic impingement syndrome (52%) or even anterior instability (39%). Surgical treatment of type II SLAP lesions should not be undertaken lightly in overhead athletes. If a 3-month rehabilitation period followed by a return to sports over the following 3 months does not allow the athlete to return to his or her preinjury level, diagnostic arthroscopy with SLAP repair is a reasonable option and can yield excellent results using the proper techniques. The technique described in detail in this article and our video can be technically demanding, but with the key points outlined, it can be reproduced and provide excellent results for overhead athletes undergoing SLAP repair. By not violating the rotator cuff, using a mattress configuration and keeping the suture knot away from the articular surface, and by not going anterior to the biceps tendon for repair, external rotation and strength can be preserved, leading to an excellent result with a predictable return to play for overhead athletes.
