Non-operative Management of Acute Knee Injuries.

PURPOSE OF REVIEW: Acute knee injuries are commonly encountered in both the clinical and sideline setting and may be treated operatively or non-operatively. This article describes an evidence-based approach to non-operative acute knee injury. This includes history, physical exam, imaging, and initial management. In addition, the non-operative management of three such injuries-ligament injury, meniscus injury, and patellar dislocation injury-will be discussed via a case-based practical approach. RECENT FINDINGS: Aside from grade III ACL tears, most acute knee ligament injuries, especially in the absence of other concurrent injuries, can be treated non-operatively. There is new evidence that acute traumatic meniscus tears in those younger than 40 can be successfully treated non-operatively and can do equally, as well as those that undergo surgery, at 1 year out from injury. Based on the current literature, a short period of knee bracing in extension with progression to weightbearing to tolerance is recommended after initial patellar dislocation. Many of the most common acute knee injuries, including MCL tears, meniscus tears, and patellar dislocations, can be managed non-operatively. A detailed systemic approach to initial evaluation, including pertinent history, physical exam, and appropriate imaging, is essential and complementary to the subsequent non-operative treatment algorithm.

Medical Supervision of Illinois Public and Private High School Athletics.

BACKGROUND: High-school sports participation in the United States has increased over the years with a corresponding increase in the number of injuries. Leading medical and sports organizations nationwide advocate for an increase in proper medical supervision of athletes. OBJECTIVES: To analyze athletic medical coverage in Illinois high schools and compare differences between public and private Illinois high school. METHODS: A survey addressing various components of sports medical coverage was distributed in 2018 to all 810 Illinois High School Association (IHSA) high schools to be completed electronically. RESULTS: The response rate was 50% (407/810 schools). Of the responding schools, 14% were private high schools and 86% public high schools. An orthopedic surgeon, family doctor, pediatrician, or another type of physician were present on sidelines in 9.2% of private high schools and 8.5% of public high schools. Athletic trainers (ATs) were present on sidelines in 91% of private high schools and in 79% of public high schools. There was 68% of private high schools reporting coaches trained in CPR versus 85% in public high schools. Both private and public high schools had high rates of having written emergency action plans (89% vs 91%), AED on site (100% vs 99%), written concussion management protocols (96% vs 97%). CONCLUSION: Our study found similar rates of high school medical coverage as compared to national studies, with some significant differences found between private and public high schools. Most Illinois high schools had high rates of having written EAPs, concussion management protocols and AEDs on site. Overall, an increase of medical supervision and emergency preparedness is needed, which should come in the form of increasing AT and physician presence alongside community and school engagement for improved implementation of coverage.

Medical Supervision of High School Athletics in Chicago: A Follow-up Study.

BACKGROUND: High school sports participation in the United States has increased dramatically over the past 25 years. A corresponding increase in the number of injuries has been noted, particularly in contact sports such as football. This has led medical and sports organizations nationwide to advocate for proper medical supervision of athletes at games and practices. PURPOSE: To gather information from Chicago public high schools to gauge how medical supervision for high school sports has changed in 2017 compared with 2003. STUDY DESIGN: Cross-sectional study. METHODS: Survey questionnaires were sent to the athletic directors of all 99 Chicago public high schools to complete via email. The questionnaire survey contained the same questions as in a survey conducted in 2003 by Tonino and Bollier, with the addition of 4 novel questions relating to emergency action plans (EAPs), automated external defibrillators, concussion management policy, and tackling progression drills. RESULTS: The response rate was 66.67% (66/99 schools). Of the 66 responding schools, all with football programs, no school had a physician on the sideline at home games (decrease from 10.6% in 2003), 37.9% had an athletic trainer present (increase from 8.5% in 2003), and 63.6% had a paramedic available (decrease from 89.4% in 2003). In 2017, 65.6% of responding schools had a coach certified in cardiopulmonary resuscitation (CPR) available at practice to handle medical problems, compared with 89.4% in 2003 (P < .001). Regarding the 4 novel questions, 93.9% of the responding schools had proper tackling progression drills in place, followed by 89.1% who had appropriate EAPs and 93.9% with concussion management protocols, including return-to-play and return-to-learn protocols. CONCLUSION: Although significant improvement was found in athletic trainer coverage, especially at games, physician coverage was lacking and fewer coaches were certified in CPR in 2017 compared with 2003. EAPs and concussion management protocols were present in most Chicago public high schools. Overall, greater medical supervision is needed, which we believe should come in the form of increased athletic training and physician involvement and coverage, given that expert, expedited medical care saves lives.

Competitive Diving Principles and Injuries.

Competitive diving is a sport that has evolved over time to become an admired present-day aquatic sport, especially in the Olympic setting. Despite its popularity, sparse research has been written as it applies to our understanding of competitive diving injuries. This article attempts to discuss common principles of competitive diving as they relate to the sport, especially as it relates to the extreme physical forces encountered by the diver and also the repetitive nature of diving. Next, these principles will be applied in the context of musculoskeletal and medical diving specific injuries.

A practical radiographic visual estimation technique for the prediction of developmental narrowing of cervical spinal canal.

OBJECTIVES: To determine if visual spinal canal percentage of facet overlap could be used as a rapid visual pre-screening test to detect developmental bony spinal canal narrowing on lateral cervical radiographs. METHODS: Lateral cervical spine radiographs with radiology report documenting developmental narrowing of the spine canal were retrospectively identified. Cohort was supplemented with additional images without such documentation. Utilizing a radiology work station, one reader (Orthopaedics) calculated the Torg ratio at C3-C6. Two readers (Radiology, Primary Care Sports Medicine) visually estimated percentage (≥80, ≥90, 100%) of spinal canal overlaid by facet articulations C3-C6 for all cases independently. Statistical analysis included accuracy tests and kappa test for comparing the gold standard and inter-, intra-observer reliability, respectively. RESULTS: 96 lateral images were included; 25 had abnormal radiology reports. High specificity (range, 91-93%) and true negative predictive values (range, 88-93%) achieved consistent statistical significance for relationship between facet/canal overlap and Torg ratio for both combined and individual data points. Sensitivity values (range, 59-75%) showed a trend toward association, with statistical significance for only the C3 level at 80% overlap. Interobserver agreement was substantial. Intra-observer reliability was moderate to perfect. CONCLUSION: Visual estimation of percentage of facet overlap of the spinal canal is a valid tool to identify individuals with potential developmental narrowing of the spinal canal as a screening prompt to select which patients may need formal calculation utilizing accepted metrics. Advances in knowledge Visual estimation of percentage of facet overlap from lateral radiographs can predict developmental narrowing of cervical spinal canal.

Update: soccer injury and prevention, concussion, and chronic groin pain.

Soccer, or football, as it is known in much of the world, is one of the most popular sports in the world. The purpose of this article was to provide a concise update on select soccer-specific medical issues published in the last year as they relate to soccer injury and prevention, concussions, and chronic groin pain. Both the Fédération Internationale de Football Association and the Union of European Football Associations published data from their longstanding injury tracking systems, providing foundation for further research. Concussion research continues to drive much interest, especially as it relates to heading and the controversy of subconcussive trauma. Lastly, our understanding of chronic groin pain continues to be refined as we try to understand the complexity of its pathophysiology and attempt to standardize a multispecialty approach of diagnosis and treatment.

Effect of education and language on baseline concussion screening tests in professional baseball players.

OBJECTIVE: The purpose of the present study was to investigate the possible effects of sociocultural influences, specifically pertaining to language and education, on baseline neuropsychological concussion testing as obtained via immediate postconcussion assessment and cognitive testing (ImPACT) of players from a professional baseball team. DESIGN: A retrospective chart review. SETTING: Baseline testing of a professional baseball organization. PARTICIPANTS: Four hundred five professional baseball players. INDEPENDENT VARIABLES: Age, languages spoken, hometown country location (United States/Canada vs overseas), and years of education. MAIN OUTCOME MEASURES: The 5 ImPACT composite scores (verbal memory, visual memory, visual motor speed, reaction time, impulse control) and ImPACT total symptom score from the initial baseline testing. RESULTS: The result of t tests revealed significant differences (P < 0.05) when comparing native English to native Spanish speakers in many scores. Even when corrected for education, the significant differences (P < 0.05) remained in some scores. CONCLUSIONS: Sociocultural differences may result in differences in computer-based neuropsychological testing scores.
