Anatomic factors associated with degeneration and fraying of the coracoacromial ligament Open
Background: The coracoacromial ligament (CAL) is frequently observed to be damaged during arthroscopy and it is unclear how demographic, anatomic, and radiographic factors are related to CAL degeneration in full-thickness rotator cuff tear…

Photodynamic therapy for <i>Cutibacterium acnes</i> decolonization of the shoulder dermis Open
Introduction Cutibacterium acnes (C. acnes) is a common source of infection in shoulder surgery. 5-Aminolevulinic acid (5-ALA) is a naturally occurring metabolite of C. acnes that creates an exothermic reaction when activated by blue light…

Profibrotic behavior of fibroblasts derived from patients that develop posttraumatic shoulder stiffness Open
Background and Aims Arthrofibrosis is a severe scarring condition characterized by joint stiffness and pain. Fundamental to developing arthrofibrotic scars is the accelerated production of procollagen I, a precursor of collagen I molecules…

Post-operative Urinary Dysfunction Following Shoulder Surgery: Rates and Risk Factors. Open
Worsening of urinary function following shoulder surgery is common. The AUA score may be used to identify at-risk patients and to track changes in urinary function post-operatively. Men with a diagnosis of BPH are at particularly high risk…

Periprosthetic joint infections of the shoulder: A 10-year retrospective analysis outlining the heterogeneity among these patients Open
Background Diagnosis and treatment of shoulder periprosthetic joint infection is a difficult problem. The purpose of this study was to utilize the 2018 International Consensus Meeting definition of shoulder periprosthetic joint infection t…

Is D-dimer a Reliable Serum Marker for Shoulder Periprosthetic Joint Infection? Open
Background The diagnosis of periprosthetic shoulder infection continues to be difficult to make with confidence. Serum D-dimer has proven to be effective as a screening tool for periprosthetic joint infection in other major joints; however…

Postoperative stiffness after reverse total shoulder arthroplasty Open
Purpose The purpose of this study was to evaluate the rate and risk factors for stiffness after reverse shoulder arthroplasty and the ramifications on the patient-reported outcomes. Method A consecutive series of patients who underwent rev…

<i>Cutibacterium acnes</i> is Isolated from Air Swabs: Time to Doubt the Value of Traditional Cultures in Shoulder Surgery? Open
We demonstrate that the two most commonly cultured organisms (C. acnes and CNS) during revision shoulder arthroplasty are also the two most commonly cultured organisms from negative control specimens. Contamination can come from air…
View article: <i>Cutibacterium acnes</i> is less commonly identified by next-generation sequencing than culture in primary shoulder surgery
<i>Cutibacterium acnes</i> is less commonly identified by next-generation sequencing than culture in primary shoulder surgery Open
Introduction High rates of positive Cutibacterium acnes cultures from primary shoulder surgery make positive cultures in the revision surgery setting difficult to interpret. Our goal was to determine concordance between culture and next-ge…

Failure of Anatomic Total Shoulder Arthroplasty with Revision to another Anatomic Total Shoulder Arthroplasty. Open
Results of revision aTSA to aTSA were unpredictable and the revision rate was high. The cases that do not undergo revision had satisfactory, but inconsistent functional results. Reverse arthroplasty may be more reliable in this patient pop…
