Randomized Controlled Trial
Is early passive motion exercise necessary after arthroscopic rotator cuff repair?
Early passive motion exercise has been the standard rehabilitation protocol after rotator cuff repair for preventing postoperative stiffness. However, recent approaches show that longer immobilization may enhance tendon healing and quality. ⋯ Early passive motion exercise after arthroscopic cuff repair did not guarantee early gain of ROM or pain relief but also did not negatively affect cuff healing. We suggest that early passive motion exercise is not mandatory after arthroscopic repair of small to medium-sized full-thickness rotator cuff tears, and postoperative rehabilitation can be modified to ensure patient compliance.

The administration of amide-type local anesthetics to cartilaginous tissues has revealed potential chondrotoxicity. ⋯ Single-dose injections of 1% lidocaine may be significantly chondrotoxic, and further investigation regarding in vivo chondrotoxicity appears warranted.

Knowledge of injury mechanisms and game situations associated with head injuries in girls' high school lacrosse is necessary to target prevention efforts. ⋯ Comprehensive video analysis suggests that play near the goal at the varsity high school level is associated with head injuries. Absence of penalty calls on most of these plays suggests an area for exploration, such as the extent to which current rules are enforced and the effectiveness of existing rules for the prevention of head injury.

In the United States (US), an estimated 300,000 sports-related concussions occur annually. Among individuals 15 to 24 years of age, sports are second only to motor vehicle crashes as the leading cause of concussions. ⋯ Although interest in sports-related concussions is usually focused on full-contact sports like football and ice hockey, concussions occur across a wide variety of high school sports. Concussion rates vary by sport, gender, and type of exposure. An understanding of concussion rates, patterns of injury, and risk factors can drive targeted preventive measures and help reduce the risk for concussion among high school athletes in all sports.

Comparative Study
Snowboarding injuries: trends over time and comparisons with alpine skiing injuries.
Participation in snowboarding as a winter sport is comparable to alpine skiing concerning the demographics of the participants, risk of injury, and variation in types of injuries sustained. ⋯ Injury rates in snowboarders have fluctuated over time but currently remain higher than in skiers. Wrist, shoulder, and ankle injuries are more common among snowboarders, while knee ligament injuries are more common in skiers. Injured snowboarders were significantly younger, less experienced, and more likely to be female than injured skiers or snowboard control participants. We did not find any evidence that those who spend time in terrain parks are overrepresented in the injury population.
