Project description:Isolated posterior instability is well described but relatively uncommon, accounting for less than 10% of all shoulder instability cases. When nonoperative management fails, surgical outcomes demonstrate improved patient-reported outcomes with a high level of return to sport. Knotless suture anchor and "all-suture" suture anchor technology are now available and used for instability procedures in the shoulder. This technical description describes knotless "all-suture" suture anchor fixation for isolated posterior labral tears.
Project description:Extensive glenoid labral tears, whether the result of repetitive instability or first-time dislocation, compromise the mechanical stability of the glenohumeral joint due to disruption of the anterior, inferior, posterior, and/or superior portions of the labrum. These lesions often result in recurrent multiplanar instability and pain that is nonresponsive to conservative management and difficult to diagnose due to variability in clinical presentation and advanced imaging findings. Arthroscopic repair techniques to address symptomatic shoulder instability have showed positive patient-reported outcomes, low failure rates, and high return-to-sport rates. The evolution of knotless suture anchors offers a fixation method that has proven to be functionally equivalent to knotted suture anchors while avoiding the risks of knotted anchors (knot loosening, knot migration, articular abrasion) and allowing easier placement and decreased operative time. The purpose of this technique is to describe our preferred method to treat a 270° labral tear through arthroscopic knotless anchor repair and demonstrate the expanded application of this technique for extensive glenoid labral pathology.
Project description:In the management of multidirectional type of shoulder instability (MDI), arthroscopic surgical stabilization is a preferred treatment option after failed conservative therapy regimens because of the ability to easily access all aspects of the capsule with one surgical procedure. As arthroscopic techniques have evolved, factors critical to postoperative success have been elucidated. Currently, optimal arthroscopic treatment of MDI involves circumferentially restoring labral integrity, a tailored, patient-specific surgical reduction of capsular volume, and adequately managing potential lesions of the biceps anchor. The purpose of this article and accompanying video is to present our technique for arthroscopic circumferential labral repair and pancapsular shift using knotless all-suture anchors in the setting of MDI with a concurrent type II SLAP lesion.
Project description:Posterior instability, although an uncommon shoulder pathology, is reported most frequently in the athletic population. Arthroscopic repair has emerged as the main surgical treatment modality for posterior instability. However, when compared with arthroscopic repair for anterior instability, the results of this procedure remain suboptimal. The creation of iatrogenic defects in the capsule, due to cannula placement, is a possible culprit. Because these defects typically do not heal satisfactorily, they become stress risers within the capsule itself, which may lead to recurrent instability or an otherwise compromised repair construct. Therefore, we find that routine intraoperative repair of these defects after repair can reduce the risk of injury and possibly improve long-term outcomes. In this article, we illustrate the repair of a posterior segmental tear using all-suture knotless implants with closure of the posterior and posterior-inferior portals after stabilization.
Project description:Biomechanical stability is the primary function of the acetabular labrum. It provides a hip suction seal and optimal joint function. Labral tears are a common reason for hip arthroscopy, to improve patient function and to prevent long-term degenerative arthropathy. Arthroscopic labral repair has shown significantly better outcomes in return to premorbid activity levels when compared with labral debridement. Injury to the acetabular labrum is a challenge and can lead to long-term complications. In this scenario, arthroscopic labral reconstruction has shown good results regarding patient subjective and objective outcomes. We describe a technique for complete arthroscopic labral reconstruction using tensor fascia lata allograft.
Project description:The Bennett lesion is an extra-articular ossification at the posteroinferior glenoid rim that is common among overhead-throwing athletes. While the majority of these exostoses are asymptomatic, some may cause posterior shoulder pain during throwing motion and frequently have concomitant posterior labral tears. Multiple approaches to Bennett lesion resection have been described, and there is debate regarding the need for capsulotomy, posterior labral repair, and capsular repair. The purpose of this article is to describe our preferred surgical technique for arthroscopic Bennett lesion resection and posterior labral repair using knotless all-suture anchors.
Project description:Medial meniscus posterior root tears can lead to rapid progression of knee arthritis because of loss of the stress distribution function of the meniscus. Medial meniscus root repair can restore stress distribution and improve clinical outcome. In cases of medial meniscus root tears with meniscal extrusion, centralization may help reduce extrusion and protect the root repair. Presented here is a technique for transtibial medial meniscus root repair with centralization using knotless suture anchors, building on previously developed techniques.
Project description:Posterior shoulder instability, although relatively rare in the general population, is more commonly seen in athletes, especially those in contact sports. Although nonoperative treatment has been associated with satisfactory results in the setting of posterior shoulder instability, conservative management may ultimately fail and lead to recurrence particularly in young, male patients. Both arthroscopic and open repair techniques to address posterior instability have been described, with each showing positive patient-reported outcomes, low risk of recurrence, and considerably high return-to-sport rates. In particular, arthroscopic treatment includes the following: capsular plication and knotted and/or knotless suture anchor fixation. The purpose of this technique is to describe our preferred technique to treat recurrent posterior shoulder instability through arthroscopic labral repair using knotless suture anchor fixation.
Project description:PurposeThe purposes of this study were to determine the incidence of anterior shoulder pain in young athletes undergoing arthroscopic posterior labral repair for symptomatic unidirectional posterior shoulder instability and in patients with preoperative anterior shoulder pain treated without biceps tenodesis at the time of arthroscopic posterior labral repair who underwent a revision biceps tenodesis procedure at short-term follow up.MethodsA retrospective review was performed at a single institution over a 24-month period. The study included young patients who underwent an arthroscopic posterior labral repair for symptomatic unidirectional posterior shoulder instability. The electronic medical record, magnetic resonance arthrograms, and arthroscopic images were reviewed to exclude patients with posterior labral tears with anterior labral tear or SLAP (superior labrum anterior-to-posterior) tear extension on advanced imaging and arthroscopic examination. Data collected included the presence of preoperative tenderness to palpation of the biceps tendon in the groove, the results of a preoperative Speed test, postoperative Subjective Shoulder Value, the presence of postoperative anterior shoulder pain, and the need for a secondary biceps tenodesis.ResultsWe identified 65 patients who underwent arthroscopic labral repair for posterior shoulder instability. From this cohort, 26 patients with symptomatic unidirectional posterior shoulder instability underwent an arthroscopic posterior labral repair. The incidence of preoperative anterior shoulder pain with Zone 2 biceps groove tenderness and a positive Speed test was identified in 20 of 26 patients (76.9%). Of 26 patients, 5 (19%) had concomitant biceps tenodesis. The median postoperative Subjective Shoulder Value was 80 (interquartile range, 60-90) at median follow-up of 2.1 years. Of the 20 patients with preoperative anterior shoulder pain, 8 of 20 (40%) reported persistent anterior pain. One patient (4.7%) underwent a secondary biceps tenodesis.ConclusionsThere is a high incidence of anterior shoulder pain and Zone 2 biceps groove tenderness in patients undergoing isolated arthroscopic posterior labral repair for unidirectional posterior shoulder instability. At short-term follow-up, few patients required a secondary biceps tenodesis procedure; however, 30% of patients had persistent anterior shoulder pain.Level of evidenceLevel IV, retrospective diagnostic case series.
Project description:Posterior shoulder instability (PSI) is a relatively less common form of instability that frequently affects young overhead or contact athletes. The etiology of PSI may be traumatic or atraumatic, with establishment of the diagnosis being more difficult in cases of atraumatic instability. Surgical management of PSI has evolved from open techniques to arthroscopic techniques. Posterior stabilization has commonly been performed with 2 posterior working portals with the patient in the lateral decubitus position. The objective of this Technical Note is to describe a technique for posterior labral repair using all-suture anchors with the patient in the beach-chair position via 1 working portal with capsular closure.
