In order to assess the existing literature evaluating the diagnosis and management of MLKIs, we performed a scoping review1 based on established methodology.2 3 This process established that the majority of the 417 articles identified

Collisions and physical contact with other athletes, or the playing environment, are fundamental aspects of many sports. These can result from intentional high-impact actions (eg, tackling in rugby and throws in judo), and/or incidental actions (e.g., contesting an aerial challenge in netball and blocking a ball in football). With the unprecedented growth and professionalisation of women’s sports that

Comparing apples to oranges is rational when comparing different fruits; comparing apples to beans is something else entirely. Likewise, injury prevention trials proposing warm-up interventions should strive to deliver reasonable comparisons. The contents and dosage of the intervention and control warm-ups may vary, especially in the context of pragmatic trials, but should be appropriately described

The summer of 2024 was dominated by spectacular sporting events, first and foremost by the Paris Olympic and Paralympic Games.
