Patient Satisfaction with Postoperative Telemedicine Versus In-Office Visits Following Primary Hip Arthroscopy: A Prospective Observational Study Before and During the COVID-19 Pandemic.

The purpose of this study was to compare satisfaction with postoperative telemedicine visits versus in-office visits among patients undergoing primary hip arthroscopy. A prospective cohort study was conducted involving subjects ≥18 years old undergoing primary hip arthroscopy at a single center from January 2020 to February 2021. Subjects chose between a telemedicine or in-office visit for 6-week follow-up.

Anterior Shoulder Instability Evolution of Principles and Surgical Treatment.

Anterior shoulder instability has been a common shoulder problem since the earliest of human civilizations. Over the course of thousands of years, our understanding regarding shoulder instability and treatment options have evolved tremendously. Specifically, over the past several decades we have seen a gradual but substantial development in our understanding of the natural history of anterior shoulder instability with and without surgical treatment.

Bone Marrow-Derived Mesenchymal Stromal Cells Enhanced by Platelet-Rich Plasma Maintain Adhesion to Scaffolds in Arthroscopic Simulation.

Purpose: To assess the response of bone marrow-derived mesenchymal stromal cells (bMSCs) enhanced by platelet-rich plasma (PRP) in the setting of a normal human tendon (NHT), a demineralized bone matrix (DBM), and a fibrin scaffold (FS) with simulated arthroscopic mechanical washout stress.

Methods: Bone marrow was aspirated from the humeral head and concentrated. BMSCs were counted, plated, and grown to confluence.

The Influence of Trocar Fenestration and Volume on Connective Tissue Progenitor Cells (Stem Cells) in Arthroscopic Bone Marrow Aspiration From the Proximal Humerus.

Purpose: To evaluate the number of connective tissue progenitor cells (CTPs) and nucleated cells obtained during bone marrow aspiration (BMA) from the proximal humerus using either a fenestrated or a nonfenestrated trocar and determine differences in varying amounts of aspiration volume. The first hypothesis was that the number of CTPs extracted with the fenestrated trocar would be greater due to its potential to extract more cells through its fenestrations. The second hypothesis was that using consecutive aspirations with either trocar would provide a consistent number of CTPs and nucleated cells throughout the aspiration with no significant decrease of cells at the end.
