Clinical Outcome After Lateral Ulnar Collateral Ligament Reconstruction in an Adolescent Baseball Player: A Case Report
We report a 17-year-old right-handed pitcher with symptomatic PLRI after an injury to his LUCL during a baseball game. Having failed 8 months of conservative treatment, a LUCL reconstruction using the modified O'Driscoll technique was performed with the contralateral gracilis autograft. At 5-year follow-up, an excellent patient-reported outcome was achieved and the patient continued to play baseball at the recreational level. This type of injury is rarely reported in adolescent baseball players, and improving our knowledge of the long-term outcomes is crucial to assist clinicians in counseling patients about expectations a...

Epidemiology of Competition Injuries in Elite European Judo Athletes: A Prospective Cohort Study
Conclusions: Weight division (middle) and fight outcome (losing) are significant risk factors for injury. The IIR in elite adult judo competition is lower than that in taekwondo and karate. Future research is encouraged to investigate the actual severity of judo injuries, and to investigate potentially modifiable risk factors to mitigate the risk of injury in judo.

Patient, Injury, Assessment, and Treatment Characteristics and Return-to-Play Timelines After Sport-Related Concussion: An Investigation from the Athletic Training Practice-Based Research Network
Conclusions: Most concussion cases documented in this study were not on-field emergencies, as indicated by their normal clinical examinations and the lack of immediate referral to an emergency department. However, certain aspects of the clinical examination were often not assessed during the initial evaluation. These findings describe concussion assessment and recovery in adolescents and reinforce the need for a standardized approach to concussion assessment and appropriate documentation.

Athletic Remodeling in Female College Athletes: The “Morganroth Hypothesis” Revisited
Background: There is limited data regarding ventricular remodeling in college female athletes, especially when appropriate scaling of cardiac dimensions to lean body mass (LBM) is considered. Moreover, it is not well established whether cardiac remodeling in female athletes is a balanced process with proportional increase in left ventricular (LV) mass and volume or the right and LV size. Methods: During the preparticipation competitive screening, 72 female college athletes volunteered to undergo dual energy x-ray absorptiometry scan for quantification of LBM and comprehensive 2D echocardiography including assessment o...

American Medical Society for Sports Medicine Position Statement on Concussion in Sport
Abstract: Sport-related concussion (SRC) is a common injury in recreational and organized sport. Over the past 30 years, there has been significant progress in our scientific understanding of SRC, which in turn has driven the development of clinical guidelines for diagnosis, assessment, and management of SRC. In addition to a growing need for knowledgeable health care professionals to provide evidence-based care for athletes with SRC, media attention and legislation have created awareness and, in some cases, fear about many issues and unknowns surrounding SRC. The American Medical Society for Sports Medicine formed a wri...

An Autologous Leukocyte-Reduced Platelet-Rich Plasma Therapy for Chronic Injury of the Medial Collateral Ligament in the Knee: A Report of 3 Successful Cases
We report on successful treatment of chronically symptomatic MCL injuries in 3 patients using autologous leukocyte-reduced platelet-rich plasma (PRP) injections. There were 3 men with a mean age of 39.3 years and a mean disease duration of 10 months. Magnetic resonance imaging showed discontinuities of superficial layers and thickness of deep layers in the proximal MCL. After PRP injections, all cases returned to their sport activities at a previous level as without symptoms, and complete healing of proximal ligaments was identified on magnetic resonance images. The outcomes indicated that PRP injections led to successful ...

Proximal Radial Head Fractures in Young Gymnasts: A Case Series of Newly Described Overuse Injuries
We report a case series of unilateral Salter-Harris IV fractures of the proximal radial heads in young female gymnasts. To date, there are no previous reports of such injuries in gymnastics. In all 3 athletes, no significant injury preceded presentation or diagnosis. Radiographs and magnetic resonance imaging showed fractures and associated bone marrow edema of the proximal radial head, respectively. All but 1 was treated nonoperatively with success. Given the lack of acute trauma, lack of large effusion, and good range of motion at presentation, these injuries are believed to be chronic in nature and related to overuse. T...

Sensitivity of the Cogstate Test Battery for Detecting Prolonged Cognitive Alterations Stemming From Sport-Related Concussions
Conclusions: These results suggest that using the raw scores over clinical variables increases the sensitivity of the test battery. Moreover, these results add another piece of evidence suggesting that concussive injuries are associated with subtle long-term alterations in aspects of higher cognition. Importantly, these deficits would have gone unobserved if we had relied solely on automated clinical variables. The current results further our scientific understanding of concussion and may be used to advance clinical practices. (Source: Clinical Journal of Sport Medicine)
