Background: While surgical stabilization is typically recommended for patients with recurrent shoulder instability, the management of first-time shoulder dislocation (FTSD) presents a unique challenge for health care providers.

Purpose: To assess the efficacy of arthroscopic Bankart repair (ABR) compared with nonoperative management for FTSDs.

Study Design: Review.

Background: The National Hockey League (NHL) saw an unprecedented disruption to the competitive calendar due to the COVID-19 pandemic in March of 2020. Returning to play following an abrupt cessation of activity is a known risk factor for athletes.

Purpose: To analyze the occurrence and severity of events (injury and illness) in the NHL and to understand any differences in occurrence and severity between pre-pandemic seasons and seasons that immediately followed.

Collagenase digestion (d) and cellular outgrowth (og) are the current modalities of meniscus fibrochondrocytes (MFC) isolation for bioengineering and mechanobiology-related studies. However, the impact of these modalities on study outcomes is unknown. Here, we show that og- and d-isolated MFC have distinct proliferative capacities, transcriptomic profiles via RNA sequencing (RNAseq), extracellular matrix (ECM)-forming, and migratory capacities.

Background: Mechanical unloading of the knee articular cartilage results in cartilage matrix atrophy, signifying the osteoarthritic-inductive potential of mechanical unloading. In contrast, mechanical loading stimulates cartilage matrix production. However, little is known about the response of meniscal fibrocartilage, a major mechanical load-bearing tissue of the knee joint, and its functional matrix-forming fibrochondrocytes to mechanical unloading events.
