Background: A ruptured Achilles tendon (AT) can sideline a player for 6 to 12 months and reduce their power rankings by more than 50%. Previous research has compared AT rupture rates in different game conditions.
Purpose: To determine environmental and physiological risk factors for AT tears, given the minimal amount of research on AT ruptures in the National Football League (NFL).
Study Design: Case series; Level of evidence, 4.
Methods: NFL players with a diagnosed AT tear between 2009 and 2016 were selected as the study population for this retrospective analysis. Data on NFL injury were collected from an established database composed of publicly available information. Player profiles were employed to determine position, team, and game statistics at the time of injury. The proportion of NFL rookies was approximated by summing the number of draft picks and the number of signed, undrafted free agents and measured against the number of roster spots before the season.
Results: Between 2009 and 2016, there were 101 documented AT tears. Of these, 64% (65/101) occurred before the official season, including preseason games. Of the 36 tears that occurred in-season, 34 were during games. Overall, 29% (19/65) of the preseason tears occurred in rookies and 100% (36/36) of the in-season tears affected nonrookies. Of the rookies with AT ruptures, 42.11% returned to play in the NFL, while 62.20% of the nonrookies came back to partake in future seasons. Despite an average age of 26.7 years, the tear distribution was bimodal with players aged 24 and 36 years exhibiting the highest rates of tear.
Conclusion: In our review of AT tears in NFL athletes, a large percentage of the tears occurred in rookie players, especially during the preseason. We also found that tears during the season occurred in only nonrookies, suggesting that the preseason is when rookies experience the greatest risk for injury.

Orthopedic Surgery, University of Alabama at Birmingham School of Medicine, Birmingham, USA.
Introduction A subject of ongoing debate within the National Football League (NFL) community revolves around the comparative risk of anterior cruciate ligament (ACL) injuries on natural versus artificial turf field surfaces. There have been mixed results as to whether there is a difference in injury rates depending on the playing surface and what factors might play a role in affecting these rates. Methods This study aims to compare the incidence of in-game knee ligament tears in the NFL during the 2020-2023 seasons.

Background: The underlying shoulder pathology in radiographic superior escape of the humeral head and association between acromiohumeral interval (AHI) on radiographs and magnetic resonance imaging (MRI) are poorly understood.
Methods: A retrospective review of shoulder radiographs and MRI scans was undertaken. AHI was measured using both modalities.
The Influence of Initial Surface Roughness on the Current-Carrying Friction Process of Elastic Pairs.

National United Engineering Laboratory for Advanced Bearing Tribology, Henan University of Science and Technology, Luoyang 471023, China.
To investigate the effect of the initial surface roughness on the performance at the initial stage of the current-carrying friction of an elastic friction pair, experiments were conducted using a self-made current-carrying friction and wear tester. The results indicate that under the experimental conditions, the lifespan of the friction pair decreases as the surface roughness and load decrease. When the surface roughness is Ra 0.

Popliteal cysts (PCs) are occasionally accompanied by knee osteoarthritis (OA) and varus malalignment. However, whether concomitant arthroscopic excision of PCs with medial open-wedge high tibial osteotomy (MOWHTO) improves the osteoarthritic environment remains unclear. Therefore, this study assessed serial changes in C-size, medial meniscus extrusion (MME), and cartilage status for up to 2 years following an MOWHTO.

Purpose: To describe and evaluate the efficacy and safety of lacrimal sac to conjunctiva reconstructive ostomy for proximal lacrimal system reconstruction.
Methods: This retrospective study included 41 patients (32 cancer and 9 trauma; 36 primary and 5 secondary) who underwent lacrimal sac to conjunctiva reconstructive ostomy. The technique involves creating a direct connection between a surgical opening in the lacrimal sac, which maintains its bony attachments to prevent ostomy occlusion, and the medial conjunctiva (medial fornix, bulbar, and palpebral).
