Loosening of the glenoid component is a frequent cause of failure of total shoulder arthroplasty (TSA). The etiology of glenoid component loosening is multifactorial and includes aseptic osteolysis, rotator cuff insufficiency, soft tissue instability, and infection. A loose glenoid component is frequently associated with a substantial loss of glenoid bone, which necessitates additional procedur...

Background: Successful repair of a torn rotator cuff may prevent progression to rotator cuff arthropathy. However,previous studies have shown a substantial rate of failure after rotator cuff repair and characteristics of surgicallyrepaired rotator cuffs that go on to shoulder arthroplasty have not been fully elucidated. The purpose of this study wasto determine the patient cha...

The Comprehensive® Shoulder Solutions’ Modular Hybrid Glenoid from Biomet is a revolutionary design for replacement of the glenoid in total shoulder arthroplasty. It provides three outer pegs and three central peg options for surgical implantation. In vitro testing of the Modular Hybrid Glenoid resulted in mean axial pull-out peak loads ranging from 209 to 303 lbf, mean inferior/superior shear ...

Massive irreparable rotator cuff tears have been troublesome entities to treat, especially in younger patients. Few good options exist, leaving most patients in recent years receiving a reverse total shoulder arthroplasty. Reverse shoulder arthroplasty carries serious risks, a limited lifespan, and no other viable options should it fail. Recent biomechanical studies have shown that the superior...

Post-instability arthropathy may commonly develop in high-risk patients with a history of recurrent glenohumeral instability, both with and without surgical stabilization. Classically related to anterior shoulder instability, the incidence and rates of arthritic progression may vary widely. Radiographic arthritic changes may be present in up to two-thirds of patients after primary Bankart repai...

BACKGROUND Preoperative opioid use has been associated with worse clinical outcomes after orthopedic surgery. The purpose of this study was to evaluate the impact of preoperative opioid use on outcomes and patient satisfaction after anatomic total shoulder arthroplasty (TSA). METHODS We identified 224 TSAs performed for primary glenohumeral joint osteoarthritis with 2- to 5-year follow-up in ...

BACKGROUND Total shoulder arthroplasty is increasingly used in the treatment of arthritis. However, the effect of total shoulder arthroplasty on health-related quality of life has not been fully established. The goal of this systematic review and meta-analysis was to characterize the change in generic and shoulder-specific health-related quality-of-life measures resulting from total shoulder ar...
