Reducing injury risk from body checking in boys' youth ice hockey.

Ice hockey is an increasingly popular sport that allows intentional collision in the form of body checking for males but not for females. There is a two- to threefold increased risk of all injury, severe injury, and concussion related to body checking at all levels of boys' youth ice hockey. The American Academy of Pediatrics reinforces the importance of stringent enforcement of rules to protect player safety as well as educational interventions to decrease unsafe tactics.

Does cryotherapy affect intraarticular temperature after knee arthroscopy?

Cryotherapy is a common modality used after arthroscopic procedures. The current authors investigated whether regions deeper than the lateral gutter experience similar temperature reductions with cryotherapy, supporting a more global temperature effect on the synovium. Thermocouple probes were arthroscopically placed intraarticularly in the medial gutter and suprapatellar pouch after routine knee arthroscopy.
