RESULTS Isokinetic quadriceps strength was consistently most difficult to pass, whereas the 6-meter timed hop and crossover hop tests were easiest. Graft type had the greatest influence on pass rates (isometric quadriceps and hamstring strength, hamstrings-to-quadriceps ratio), followed by time from surgery (6-meter timed hop and crossover hop), physical activity (IKDC), and meniscal procedure (6-meter timed hop). CONCLUSIONS Isokinetic quadriceps strength was the most difficult test to pass, and single-leg hop tests were the easiest. MDV3100 clinical trial Patient-specific factors including graft type, time from surgery, physical activity level, and meniscal procedure may influence the ability to meet return-to-activity criterion after ACLR.OBJECTIVE To evaluate whether a simple 4-factor model using self-reported data could be used to predict exercise-induced breast pain in elite female athletes. DESIGN Survey study. SETTING Online or hard-copy surveys completed at sporting competitions and training facilities around Australia. PARTICIPANTS Four hundred ninety female athletes competing nationally or internationally across 49 sports. INDEPENDENT VARIABLES A binomial logistic regression analysis was used to evaluate the strength of a predictive model that included 2 continuous independent variables (age and body mass index) and 2 binary independent variables (breast size and sports bra use). Odds ratios were also calculated to determine the likelihood of an athlete reporting exercise-induced breast pain in association with each of the 4 variables. MAIN OUTCOME MEASURES Exercise-induced breast pain was the binary dependent variable. RESULTS The model incorporating athlete age, breast size, body mass index, and sports bra use was found to be statistically significant, but weak, in its ability to predict exercise-induced breast pain in elite female athletes (correctly identified 66% of athletes). For every 1-year increase in age, a significant 2.6% increase in the likelihood of experiencing exercise-induced breast pain was observed. Athletes with medium-to-hypertrophic sized breasts were 5.5 times more likely to experience exercise-induced breast pain than athletes with small breasts. CONCLUSIONS Although the current model was not sensitive enough for use by clinicians and coaches, age and breast size were both identified as critical variables in the prediction of exercise-induced breast pain. Future research is encouraged to investigate whether incorporating additional variables such body fat percentage, bra fit, and other relevant factors can add strength to the model.OBJECTIVE To describe the preparticipation examination findings among American athletes by sex, participation level, and age. DESIGN Hypothesis-generating retrospective cohort study. SETTING Saint-Luke's Athletic Heart Center, Kansas City, Missouri. PARTICIPANTS A total of 2954 student athletes. INTERVENTIONS Athletes underwent preparticipation examination, which included history and physical, electrocardiogram, and 2-D transthoracic echocardiogram. MAIN OUTCOME MEASURES Differences noted on screening preparticipation examination by sex, participation level, and age. RESULTS Female athletes reported more symptoms than male athletes (odds ratio [OR] = 1.61; 95% confidence interval [CI], 1.32-1.97; P less then 0.0001) but had lower prevalence of abnormal electrocardiogram (OR 0.52; CI, 0.39-0.68; P less then 0.0001). College athletes reported fewer symptoms than novice athletes (OR 0.35; CI, 0.29-0.43; P less then 0.0001) with no difference in the prevalence of abnormal electrocardiography (ECG) (OR 0.96; CI, 0.73-1.26; P = 0.78). Older athletes reported fewer symptoms than younger athletes (OR 0.61; CI, 0.52-0.71; P less then 0.0001) with no difference in the prevalence of abnormal ECG (OR 1.00; CI, 0.81-1.23; P = 0.89). There were 43 athletes with clinically important findings with no difference in prevalence of these findings across sex, participation level, and age. CONCLUSIONS Among this American cohort of athletes, male athletes reported fewer symptoms and had higher prevalence of abnormal ECG findings compared with female athletes. College and older athletes reported fewer symptoms and had no difference in prevalence of abnormal ECG findings compared with novice and younger athletes, respectively. Despite these differences between groups, the prevalence of clinically important findings was comparable among groups.OBJECTIVE To investigate CrossFit-related injuries presenting to a pediatric sports medicine clinic. DESIGN Retrospective review of pediatric CrossFit-related injuries from between January 1, 2003, and June 31, 2016. SETTING Pediatric sports medicine clinic at a tertiary-level academic medical center. PATIENTS Patients with injury related to CrossFit participation. INDEPENDENT VARIABLES Sex, age, injury site, diagnosis, diagnostic imaging, and treatment. MAIN OUTCOME MEASURES Annual CrossFit-related injury proportion (%) over time. RESULTS One hundred fifteen medical identified (N = 55 female; mean age, 25.2 ± 10.4 years). Proportion of CrossFit-related injuries presenting to clinic relative to overall clinic volume consistently increased over time (Pearson r = 0.825; P = 0.022). Injury location included head (0.08%), trunk/spine (25.2%), upper extremity (27.0%), and lower extremity (47.0%). Common injured joints included knee (27%), spine (24.3%), and shoulder (16.5%). Nearly half of patients had a single diagnostic imaging (49.6%; 57 of 115). Most common diagnostics included magnetic resonance imaging (60.0%; 69 of 115), plain radiographs (51.3%; 59 of 115), ultrasound (10.4%; 12 of 115), and computerized tomographic scan (9.6%; 11 of 115). Most commonly prescribed treatments included physical/occupational therapy (38.3%; 44 of 115), activity modification (19.1%; 22 of 115), crutches/brace/splinting/compression sleeve (13.0%; 15 of 115), and non-steroidal anti-inflammatory medications (10.4%; 12 of 115). CONCLUSIONS CrossFit-related injury proportion presenting to a pediatric sports medicine clinic increased over time. A notable proportion of injuries occurred to the trunk and spine. Advanced imaging was obtained in approximately half of these youth athletes. link2 Further research in youth CrossFit athletes is required surrounding mechanism of injury to prevent future injury in this mode of training for youth athletes.INTRODUCTION Recent studies in general surgery and internal medicine have shown that female physicians may have improved morbidity and mortality compared with their male counterparts. In the field of orthopaedic surgery, little is known about the influence of surgeon gender on patient complications. This study investigates patient complications after hip and knee arthroplasty based on the gender of the treating surgeon. METHODS Using a risk-adjusted outcomes database of 100% Medicare data from a third party, an analysis of outcomes after primary hip and knee arthroplasty based on surgeon gender was performed. This data set, which provided risk-adjusted complication rates for each surgeon performing at least 20 primary knee or hip arthroplasties from 2009 to 2013, was matched with publically available Medicare data sets to determine surgeon gender, year of graduation, area of practice, and surgical volume. link3 Confounding variables were controlled for in multivariate analysis. RESULTS Of the 8,965 surgeons with idgion. LEVEL OF EVIDENCE Level III-prognostic retrospective case-control study.Hallux valgus deformity is a progressive forefoot deformity consisting of a prominence derived from a medially deviated first metatarsal and laterally displaced great toe, with or without pronation. Although there is agreement that the deformity is likely caused by multifactorial intrinsic and extrinsic factors, the best method of operative management is debated despite the creation of basic algorithms. Our understanding of the deformity and the development of newer techniques is continuously evolving. Here, we review the general orthopaedic principles of operative decision-making and management of hallux valgus deformity.INTRODUCTION Analysis of the Fundamentals of Arthroscopy Surgery Training (FAST) workstation regarding increased proficiency and retention of basic arthroscopy skills in novice subjects. METHODS First-year medical students from a single allopathic medical school performed weekly standardized FAST workstation modules for a consecutive 6 weeks. Primary outcomes evaluated were time to task completion and error rate on specific modules. Scores were analyzed using a one-way repeated measures analysis of variance design for overall trends in time and errors over the 6-week study. Psychomotor retention was analyzed after a 12-week and 24-week interlude. RESULTS Across the initial 6-week study, the average time to complete all modules at the workstation decreased significantly (P less then 0.001) with a mean reduction in the total workstation time of 21.9 minutes (s = 8.12 minutes). Weekly comparisons showed the most significant improvement from week 1 to week 2 for the total workstation time (P less then 0.001). Results after a 12-week and 24-week interval of inactivity demonstrated no significant difference in the mean workstation time or errors when compared with the original 6-week study. DISCUSSION The FAST workstation significantly improved the task performance of novice participants over a 6-week period with no significant deterioration in task performance after 12 and 24 weeks of inactivity.Overuse of the nonparetic upper extremity can lead to entrapment neuropathies in chronic stroke patients. However, little is known about the effects of cane use in subacute stage of stroke. The aim of this study was to investigate the short-term effects of cane use on the upper extremity nerves in subacute stroke patients recovering from a bedridden state. Thirty subacute hemiparetic stroke patients who were initially bedridden participated when they were able to walk with a cane. Symptoms and signs related to the median or ulnar nerves were checked, and nerve conduction studies were performed. The largest cross-sectional area (CSA) of these nerves from the wrist to elbow was measured with ultrasound. After 3 weeks of cane use, electrophysiologic and ultrasonographic reevaluation was performed. Nerve conduction studies and CSA of the nerves at the nonparetic upper extremity showed significant changes, whereas those of the hemiparetic upper extremity did not. Walking with a cane for a short period can induce the enlargement of the median and ulnar nerves at the nonparetic extremity of subacute hemiparetic stroke patients. Attention should be placed on correct cane usage from the beginning of rehabilitation.Translating and implementing research exercise programs that fit into the context of community service provisions could become part of the effort to reduce late-life disability. The purpose of this study was to examine the feasibility of a staff-led 3-Step Workout for Life program by applying a logic model in a local senior living community. The academic investigator and community fitness staff worked together to modify and implement the program protocol following the logic model. The community staff recruited residents and delivered the program. Residents were eligible if they were sedentary, showed muscle weakness, and experienced difficulty in performing activities of daily living. Feasibility was evaluated with program completion and attendance rates, adverse events, physical performance, and activities of daily living. Seventeen residents (mean age = 80 years) enrolled and 13 completed the program with an average attendance rate of 95%. No severe adverse events were reported. After program completion, participants' muscle strength and gross motor coordination of the upper extremity, as well as performance and satisfaction of activities of daily living were improved.
