Posterior Labral Injury and Glenohumeral Instability in Overhead Athletes: Current Concepts for Diagnosis and Management.

J Am Acad Orthop Surg 2020 May 13. Epub 2020 May 13.

From the Department of Orthopaedic Surgery, San Antonio Military Medical Center, San Antonio, TX (Dr. Sheean); Lexington Clinic Orthopaedics, Sports Medicine Center, Lexington, KY (Dr. Kibler); Orthopaedic Specialty Associates, Fort Worth, TX (Dr. Conway); and the Department of Orthopaedic Surgery (Dr. Bradley), University of Pittsburgh, Pittsburgh, PA.

Posterior glenohumeral instability in overhead athletes presents a unique set of challenges for both diagnosis and treatment. Although a great deal of attention has been focused on the management of injuries to the biceps-labrum complex and rotator cuff in throwers, comparatively less has been written about posterior glenohumeral instability within this unique cohort. Historically, posterior instability has been observed secondary to either acute trauma or repetitive microtrauma, usually among collision athletes, weight lifters, and rowers. Read More

Complete Repair of Massive, Retracted, and "Non-Repairable" Tears of the Rotator Cuff: The Anatomic Vector Repair.

Authors:
Graeme P Whyte

Arthrosc Tech 2020 Mar 14;9(3):e357-e365. Epub 2020 Feb 14.

Cornell University, Weill Medical College; New York Presbyterian Hospital/Queens; and New York University School of Medicine, NYU Langone Orthopedic Hospital, New York, NY, U.S.A.

Massive and retracted tears of the supraspinatus and infraspinatus tendons of the rotator cuff are associated with great pain and disability and may be considered "non-repairable," depending on the extent of injury and the experience of the treating clinician. The technique of anatomic vector repair of the rotator cuff is a surgical treatment method that enables the surgeon to accurately characterize the injury pattern and successfully repair many of these debilitating injuries anatomically in a stepwise manner, often in cases that would have otherwise been treated with a less preferable surgical procedure that does not restore native anatomy.

Authors:
Kenneth J Hunt

Arthroscopy 2020 03;36(3):714-715

University of Colorado School of Medicine.

The viscoelastic properties of suture may impact how soft tissue (such as the shoulder rotator cuff tendons) heals to bone and therefore may impact patient outcomes. Thus, it is logical to use suture material less likely to creep and elongate. Suture tape, in particular, may show superior biomechanical properties compared with standard sutures. Read More

Authors:
Erik Hohmann

Arthroscopy 2020 03;36(3):687-688

Superior capsular reconstruction remains a controversial procedure, and long-term results still need to be established. Graft thickness seems crucial and fascia lata appears superior to dermal allograft. Using a subacromial spacer by suturing dermal allograft to the subacromial bone "increases graft thickness" and reduces superior humeral head migration but increases subacromial pressures in a static laboratory cadaver model.

Editorial Commentary: Platelet-Rich Plasma in the Treatment of Rotator Cuff Tears-From Hero to Zero?

Arthroscopy 2020 03;36(3):658-659

Charité-University Medicine Berlin.

As failure rates after arthroscopic rotator cuff remain high, platelet-rich plasma (PRP) has gained interest as a potential biological augmentation to enhance bone-tendon healing. Recent research shows that delayed PRP application fails to significantly improve clinical results or decrease retear rates but may result in less fatty-infiltration of the repaired rotator cuff muscles. In combination with a lower trend toward retear, this may hint that we should not bid farewell to PRP in rotator cuff repair just yet, and whether our current enthusiasm for emerging biological strategies in rotator cuff repair is justified remains subject to additional investigation.

New Paradigms in the Throwing Shoulder: Labral Injury, Surgery, and Rehabilitation.

Instr Course Lect 2019 ;68:499-512

Knowledge regarding the importance of the superior labrum in shoulder function is evolving as biomechanical and clinical studies define the roles of the labrum in shoulder function and dysfunction. The diagnosis of the clinically significant labral injury, the alteration in labral anatomy that is associated with the production of clinical symptoms and dysfunction and requires management, is based on specific history and clinical examination findings that point to the loss of labral roles. Surgical management should address all aspects of the altered labral anatomy and repair the labral structure to allow normal labral roles without excessive biceps tension. Read More

Navigating the Research in Rotator Cuff Disease: An Evidence-Based Approach to Improved Patient Outcomes.

Instr Course Lect 2019 ;68:53-64

Rotator cuff tears are prevalent injuries, yet their management and identifying patients who will benefit from surgical intervention are controversial topics. Population studies demonstrate high rates of asymptomatic tears that, with time, show a general progression of the pathologic state. However, not all tears are or will become symptomatic or require surgical intervention. Read More

Arthroscopic Rotator Cuff Repair: A General Instructional Course Lecture.

Instr Course Lect 2020 ;69:525-550

Rotator cuff pathology is one of the most common reasons for patients to seek orthopaedic consultation. Although in many cases these issues can be resolved with proper conservative management, many of these patients benefit from surgical treatment. The goal of this instructional course lecture is to identify factors that can potentially lead to worse outcomes following repair, describe the history and techniques behind transosseous anchorless repairs, discuss subscapularis tears and their management, and to analyze the most current data regarding double-row rotator cuff repairs.

Editorial Commentary: Off the Hip or Off the Shelf? An Analysis of Autograft and Allograft as a Graft Source for Shoulder Superior Capsular Reconstruction.

Arthroscopy 2020 02;36(2):592-593

Superior capsular reconstruction can effectively relieve pain and improve function in the rotator cuff-deficient shoulder, but the optimal graft has not been determined. Multiple authors have demonstrated the effectiveness of the procedure, but bias and heterogeneity between studies do not allow valid comparative analysis of graft type. Until we can adequately compare outcomes, complications, or survival, graft availability and cost may be the greatest determinants of graft selection. Read More

Editorial Commentary: Taking a "PEEK" at Suture Anchor Composition following Arthroscopic Rotator Cuff Repair: Is Bio Really Better?

Arthroscopy 2020 02;36(2):397-399

Wake Forest Baptist Health.

The advent of modern suture anchor technology has not only revolutionized arthroscopic treatment options for management of complex shoulder pathology, but also engendered a materials science quest to identify the ultimate composition and design. What began as an open procedure with transosseous suture fixation has evolved dramatically with the widespread adoption of an arthroscopic, anchor-based technique for rotator cuff repair. Currently, a litany of commercially available "hard" and "soft" anchors are flooding the market, with limited qualitative comparisons to suggest superiority of one type. Read More

Thay Q Lee

Arthroscopy 2020 02;36(2):365-366

Pasadena, California.

One of the treatment options for a massive irreparable rotator cuff tear is superior capsule reconstruction (SCR). Biomechanically, SCR depresses and centers the humeral head on the glenoid so that the remaining rotator cuff muscles and the deltoid can provide function. Therefore, in SCR, graft characteristics such as graft type, graft thickness, and graft tension are the critical parameters contributing to the biomechanical effectiveness. Read More
