"New research shows that rule changes can spare high school ice hockey players from serious injury without altering the game’s competitive nature. The results point to new and effective ways of safeguarding countless student-athletes who play full-contact sports. Ice hockey is one of the most physical collision sports. Of the nearly 45,000 players who play at the high school level in the U.S., about 12,000 seek care in emergency departments for injuries suffered on the ice. Despite strategies to curb malicious play, the potential for serious head, neck, and spinal injury remains high, as players are still allowed to body check opponents. One promising tactic is to set a penalty-minute threshold for players who incur excessive penalties. This so-called “Fair Play” approach has been shown to reduce hockey player injuries without compromising competitive play—though only at the scale of a single tournament..."

"Can athletes’ ACLs be “trained” to resist injury? A new study published in The American Journal of Sports Medicine suggests that it’s possible. Studies on animals have shown that exercise during growth periods like puberty can “bulk up” the ACL, increasing its size and improving its mechanical properties. However, evidence of so-called “ACL hypertrophy” in human athletes is scarce. To address this gap, researchers examined the knees of 52 athletes who had been skating or diving since before puberty or since puberty onset. These types of athletes always land or jump up using the same leg, which the researchers labeled as the “dominant leg,” and thus habitually load one knee more than the other while training for their sport. Specifically, the team compared ACL and patellar tendon dimensions and knee strength between the left and right knees. They also examined how differences in ACL dimensions between knees correlated with age at training onset and with the number of years of training..."

"Tears of the anterior cruciate ligament, or ACL, are a common knee injury in American football. They also require a lengthy treatment process that includes surgical reconstruction followed by 9 to 12 months of recovery. Despite their significance, however, the circumstances that most often lead to these injuries aren’t clear. To identify these contributing factors, a US-based research team has retrospectively reviewed what players were doing and how their bodies were positioned when their ligaments tore. Surprisingly, although football is a collision sport, their study shows that ACL tears aren’t usually a contact injury. The team reached this conclusion by looking at ACL injuries occurring over three consecutive National Football League seasons. To accomplish this, they compiled live video footage from 148 events..."
