Despite advances in surgical technology, as well as generally good outcomes, repairs of full-thickness rotator cuff tears show a retear rate of 25% to 57% and may fail to provide full return of function. The repairs tend to fail at the suture-tendon junction, which is due to several factors, including tension at the repair site, quality of the tendon, and defective tissue repair. One strategy to augment repair of large to massive rotator cuff tears is the development of biological scaffold materials, composed of extracellular matrix (ECM). The goal is to strengthen and evenly distribute the mechanical load across the repair site, thus minimizing the rupture risk of the native tendon while providing the biological elements needed for healing. The promising results of ECM-derived materials and their commercial availability have increased their popularity among shoulder surgeons. In contrast to a traditional open or arthroscopically assisted mini-open approach, this completely arthroscopic technique offers the full advantages warranted by the use of a minimally invasive approach. This technical guide describes arthroscopic rotator cuff repair using an ECM graft technique.

Opioid Consumption Following Isolated and Recurrent Shoulder Dislocation and Reduction.

Background: Recurrent shoulder dislocations often lead to multiple encounters for reduction and eventual surgical stabilization, both of which involve exposure to opioids and potentially increase the risk of chronic opioid exposure. The purpose of our study was to characterize shoulder instability and compare pre- and post-reduction opioid usage in singular dislocators (SD) and recurrent dislocators (RD).
Methods: This retrospective study was performed at a single academic institution using a prospective database.
Background: There has been an increase in both primary anatomic (aTSA) and reverse total shoulder arthroplasty (rTSA) over the last decade, with rates peaking for patients aged 75 years and older. Despite aTSA being the mainstay of treatment for patients with glenohumeral arthritis in the absence of rotator cuff insufficiency, there has been an upward trend of rTSA utilization in the elderly due to concerns about rotator cuff integrity, regardless of deformity. The purpose of this study is to evaluate outcomes including pain, function, range of motion, satisfaction, and complications in patients 80 years or older following primary anatomic and reverse total shoulder arthroplasty for osteoarthritis without full thickness rotator cuff tears.
