The mission of SMR is to objectively summarize and describe the clinical relevance of research articles related to basic science, translational research, and clinical research that may be relevant to students and professionals interested in sports medicine. Furthermore, SMR aims to provide a forum for clinicians, researchers, and students in sports medicine-related fields to discuss the clinical relevance of new research.
While young physically-active cadets experience biochemical changes that reflect cartilage turnover during a four-year period, a cadet with an ACL injury may have more pronounced changes. These changes may provide insight for detecting individuals at risk for OA and developing interventions to prevent this.... Read more »

Take Home Message: Elevated body mass index and percent body fat predict for the presence of several cardiovascular risk factors for metabolic syndrome in college and high school football players. Increased activity levels in these athletes does not necessarily protect against these risk factors.... Read more »

Take Home Message: Over half of the athletes recalled concussive events in this study but did not report their problem to their supervising adult. Additionally, both concussion knowledge and attitude may play a role in reporting concussive events.
Many athletes continue to practice and play games while experiencing concussion-related symptoms. Knowledge and attitude regarding concussions are changeable factors that may contribute to concussion-reporting and care-seeking behaviors; however, fe........ Read more »

Take Home Message: A vast majority of pediatricians who care for patients with concussions follow available treatment guidelines, use medications as part of their treatment plan, use neuropsychological testing, and desire additional training in the management of sports-related concussion....

A recreational female skier may be more likely to suffer an ACL injury in the pre-ovulatory phase than during the luteal phase of her menstrual cycle. This may provide more evidence that female hormone fluctuations should be considered when we try to reduce the risk of ACL tears among females.... Read more »

Take Home Message: Osteoarthritis prevention programs could focus on certain risk factors, such as joint injury, obesity, and occupational activities.
Osteoarthritis (OA), a degenerative joint disease, affects millions of adults worldwide. There are many potential risk factors for OA, including several of interest in sports medicine: obesity, repetitive tasks (physical or occupational activity), and joint injury. It is important to understand what modifiable risk factors may exist so that w........ Read more »

Take Home Message: Athletes with attention deficit hyperactivity disorder and/or learning disabilities have lower baseline ImPACT neurocognitive scores compared to athletes without attention deficit hyperactivity disorder and learning disabilities.
Developmental, behavioral, and learning disabilities affect approximately 1 in 6 children in the United States. Children with attention deficit hyperactivity disorder (ADHD) suffer more head injuries compared with those without the disorder. Unfort........ Read more »

Take Home Message: Novice runners with pronated feet may sustain fewer injuries than neutral feet, when they wear neutral running shoes.
Among runners foot pronation is believed to be a strong predictor for athletic injury. While certain athletic shoes are commonly prescribed for individuals with pronated and supinated feet, there has been conflicting evidence to support this. Therefore, Neilsen and colleagues completed a prospective cohort study “to investigate if running distance to f........ Read more »

Take Home Message: Heading was associated with abnormal white-matter microstructure and poorer neurocognitive performance. History of concussion was not associated with altered structure.
Long-term cognitive impairments following repeated sport-related head injury is a major concern. However, the role of subconcussive impacts from soccer heading as an additional mechanism of cumulative brain injury has not been well examined. If repetitive heading causes adverse effects on the brain there cou........ Read more »

Take Home Message: Joint line tenderness and McMurray's tests used together do not necessarily improve meniscal lesion diagnosis.
Clinical prediction rules, such as the Ottawa Ankle Rules, improve clinical care and reduce healthcare costs from unnecessary diagnostic imaging. Knee meniscal clinical tests may be coupled together to yield similar results; however, the accuracy of combining meniscal special tests remains unclear. Therefore, the authors investigated the accuracy of joint l........ Read more »

Take Home Message: Computer-based neurocognitive testing methods of deciphering if a patient has a concussion may lead to false-positives, thus a gold standard is still needed.
Baseline computer-based cognitive testing is commonplace in athletics; however, more information is needed regarding the validity of comparing post-injury results with baseline performance. Therefore, Roebuck-Spencer and colleagues completed a study of 8,002 military service members (91% male, ~27 years old) to examine........ Read more »

Take Home Message: Barbotage treatment enhances functional outcome measures and reabsorption of the calcific deposit in patients with rotator cuff calcific tendinitis.
Calcific tendinitis of the rotator cuff typically occurs in patients between 30 to 50 years of age and can cause significant pain. There are several treatment options involving injections or physical therapy; however, there is no consensus to a preferred treatment; nor have there been any randomized controlled trails to evalu........

Take Home Message: Over 30% of athletes reported a previously undiagnosed concussion and these athletes may be at risk for more severe symptoms after a future impact.
Many athletes fail to report their concussion signs and symptoms (Kauet, 2003 Labotz,2005; McCrea,2004; Williamson, 2006), which predisposes them to sustaining a second blow when the brain is still recovering from the first impact. However, we still don’t know how common undiagnosed concussions may be. Identifying under-re........ Read more »

Take Home Message: While both the Y-graft and C-graft effectively stabilized the patellofemoral joint, the patients who received the Y-graft had significantly better subjective outcome scores than the patients who received the C-graft.
Patients who endure a patellofemoral dislocation are often plagued with patellofemoral instability and frequent re-injury. While multiple methods of patellar fixation exist, a gold-standard does not. Therefore, Kang and colleagues performed a randomized trial t........ Read more »

Take Home Message: As the body fatigues there may be apparent compensatory strategies employed, however, lower extremity biomechanics deteriorate as fatigue becomes greater. This may have implications for injury prevention program implementation.
Lower extremity injuries (e.g., anterior cruciate ligament [ACL], ankle sprains) tend to occur later in games or practices when athletes may be fatigued; hence, fatigue may increase susceptibility to lower extremity injuries. However, there is only........ Read more »

Take Home Message: In the United States, traumatic brain injury laws reflect a uniform, but not scientifically proven consensus about return to play time, who makes the return to play decisions, and the best delivery method to distribute educational information. None of the laws target injury prevention.
Forty-four states and Washington DC passed legislation to reduce the overall impact of traumatic brain injuries. However, there are no studies comparing the content of the laws with the curre........ Read more »

Take Home Message: Among injury athletes, having a high level of support (emotional, esteem, informational, and tangible), particularly if the athlete perceives this support, is associated with less psychological stress.
It is widely accepted that strong social support can help alleviate psychological stress. This social support also shapes how athletes may cope with the psychological stresses that arise from injury, giving the athlete a social outlet so as to not feel isolated or alone. Mitc........ Read more »

Take Home Message: Objective measurements may provide added perspective to the rehabilitation of femoroacetabular impingement not otherwise measured by self-report surveys and clinical passive range of motion.
Femoroacetabular impingement (FAI) is very common in some sports and can affect not only athletic activity but also activities of daily living. Despite functional impairments, we often evaluate the success of a treatment for FAI not with functional assessments but with just patient-rep........ Read more »
