Severe Acute Respiratory Syndrome Coronavirus 2 Reinfection: A Case Series From a 12-Month Longitudinal Occupational Cohort

Findings are described in 7 patients with severe acute respiratory syndrome coronavirus 2 reinfection from the National Basketball Association 2020-2021 occupational testing cohort, including clinical details, antibody test results, genomic sequencing, and longitudinal reverse-transcription polymerase chain reaction results. Reinfections were infrequent and varied in clinical presentation, viral dynamics, and immune response

Acetabular Labral Tears With Underlying Chondromalacia: A Possible Association With High-Level Running

Purpose: The use of hip arthroscopy has helped delineate intra-articular pathology and has enabled clinicians to further elucidate the factors responsible for injuries, such as running. The subtle development of degenerative changes may be a result of repetitive impact loading associated with this sport. This study presents a population of runners with common pathologic acetabular changes. Type of Study: Case series. Methods: Eight high-level runners with an average age of 36 years (range, 19 to 45 years) were seen for complaints of increasing hip pain with running without any history of macrotrauma. All of the patients had either run several marathons (4), were triathletes (1), Olympic middle distance runners (1), or had run more than 10 miles per week for longer than 5 years (2). Plain radiographic analysis revealed no degenerative changes and an average center-edge (CE) angle of 36.7°(range, 28°to 44°). Results: All patients underwent hip arthroscopy with labral debridement. In 6 patients (75%), a chondral injury of the acetabular cartilage underlying the labral tear was noted. In addition, 3 patients had ligamentum teres disruptions. Conclusions: It is possible that the development of these tears is the result of subtle instability, which may be exacerbated by running, eventually leading to labral tearing and possible ligamentum teres disruption. While perhaps concurrently, subtle acetabular dysplasia may play a role. Although this study does not confirm an association between running and the development of labral tears or chondral lesions in the hip, it certainly questions whether there is an injury pattern common to this population, a "runner's hip." Level of Evidence: Level IV

Seven tips for developing and maintaining a high performance sports medicine team

What should a highly effective sports medicine team look like? In 1989, Stephen Covey published his highly acclaimed book ‘The 7 Habits of Highly Effective People’. This book, with sales exceeding 25 million copies,describes how individuals contribute to successful organisations, in part by fostering interdependence among staff. The multidisciplinary and interdependent nature of high-performance sporting teams have been highlighted in BJSM editorials. Central in these commentaries has been the importance of collective decision-making and shared responsibilities. With sports medicine teams growing rapidly, sport has become somewhat of an ‘arms race’, with team owners often convinced that the secret to developing a winning franchise lies in the quality of the backroom staff. When assembling a sports medicine team to support the coaches and athletes, what should owners be looking for? What are the characteristics of a highly effective sports medicine team? Here, we provide a perspective from 12 different high-performance organisations based in four countries
