The purpose of this study was to evaluate the relative risk of anterior cruciate ligament injury in female versus male midshipmen at the United States Naval Academy. From 1991 to 1997, we recorded the incidence of anterior cruciate ligament injury during intercollegiate athletics, intramural athletics, and military training. The subjects were male and female varsity athletes, coed intramural athletes, and participants in military training consisting of the obstacle course and instructional wrestling. All patient data were collected at the time of injury. Records filed at the intramural sports office, along with a questionnaire completed by coaches and trainers, were used to estimate midshipmen exposures. Results showed that in intercollegiate soccer, basketball, and rugby, women had a relative injury risk of 3.96 compared with men. In coed soccer, basketball, softball, and volleyball, the women's relative injury risk was 1.40 compared with men. In military training, women had a relative injury risk of 9.74 compared with men. In comparing overall annual anterior cruciate ligament injury rates among midshipmen, we found that women had a relative injury risk of 2.44 compared with men. We concluded that female midshipmen have an increased relative risk of anterior cruciate ligament injury as compared with men in intercollegiate athletics, basic military training, and throughout their service academy career. This increase was not statistically significant at the intramural level of athletics.
In this young, active population, postoperative bracing does not appear to change the clinical outcomes after anterior cruciate ligament reconstruction.
The results of treatment after closed reduction of elbow dislocation vary. Twenty consecutive patients with closed posterior elbow dislocations were treated prospectively on a rapid motion, nonimmobilized functional regimen. This treatment protocol emphasizes immediate active range of motion under close supervision. No slings or splints were employed. Final range of motion averaged -4 degrees to 139 degrees. All patients attained final extension within 5 degrees of the contralateral side. Each patient achieved his final range of motion within an average of 19 days after reduction of the dislocation. Arm circumference returned to normal at an average of 6.5 days. There was one redislocation. After treatment, all patients met qualification for graduation from the U.S. Naval Academy and were able to pursue unrestricted athletic and career options. Our findings suggest that an aggressive immediate motion rehabilitation allows nearly full final elbow motion and an excellent functional outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
