Third-generation autologous chondrocyte implantation (ACI) is an established method for treatment of full-thickness cartilage defects in the knee joint. Subchondral bone marrow edema (BME) is frequently observed after ACI, with unknown pathogenesis and clinical relevance. ⋯ Midterm clinical results of the matrix-based third-generation ACI showed a substantial amount of BME over a 36-month follow-up, but this did not correlate with worse clinical outcome. Patients with femoral cartilage defects were more often affected than were those with patellar cartilage defects.

The epidemiology of football-related concussions has been extensively examined. However, although football players experience more at-risk exposure time during practices than competitions, there is a dearth of literature examining the nature of the activities or equipment worn during practice. In particular, varying levels of equipment worn during practices may place players at varying levels of risk for concussion. ⋯ Practice concussion rates are highest during fully padded practices, preseason practices, and scrimmages, suggesting that the nature, focus, and intensity of football practices affect concussion risk. In addition, coaching staff should continue to closely monitor player safety during scrimmages. Meanwhile, future surveillance should examine whether removing scrimmages, particularly those that are not fully padded, will meaningfully reduce the incidence and rate of concussions.

Presentations at scientific meetings are often used to influence clinical practice, yet many presentations are not ultimately published in peer-reviewed journals. Previously reported publication rates for orthopaedic specialties have varied from 34% to 52%. In addition, the publication rate of accepted abstracts is a strong indicator of meeting quality, and it has a potential effect on clinical practice. To date, no studies have investigated publication rates in the field of sports medicine, and specifically for abstracts presented at American Orthopaedic Society for Sports Medicine (AOSSM) meetings. ⋯ The overall publication rate of abstracts presented at AOSSM annual meetings (67.1%) was much higher than that reported for other orthopaedic meetings (34%-52%), highlighting the overall educational value and information quality of AOSSM meetings. In addition, there was a significant difference in the overall publication rates for podium and poster presentations. These data suggest that the quality and type of poster and podium presentations may not be equal, and these potential differences should be kept in mind when considering changes in clinical practice according to type of meeting presentation. Furthermore, AOSSM annual meeting program planners should consider these results when investigating ways to further improve the quality of research presented.
