Purpose To determine the objective characteristics of orthopaedic foot and ankle fellowship directors (FDs) by concentrating on the demographic characteristics, academic background, institutional history, research experience, and professional affiliations of these leaders. Methods Data for each FD were collected by searching institutional biographies, personal websites, or publicly available curricula vitae. Data collection included the following variables: age, sex, race/ethnicity, previous training institutions, residency and fellowship graduation years, advanced degrees, military affiliation, institutional loyalty, year hired, FD career timeline, total number of publications, total number of citations, and h ‐index. Results Of the 47 FDs, 44 (93.6%) were men and 3 (6.4%) were women. The mean age was 50.8 ± 9.4 years. Most orthopaedic foot and ankle FDs were white (n = 42, 89.4%), followed by Asian (n = 4, 8.5%) and black or African American (n = 1, 2.1%). The mean Scopus h ‐index, total number of publications, and total number of citations for all foot and ankle FDs were 13.3 ± 9.5, 47.5 ± 45.8, and 898.1 ± 1,040.3, respectively. Among all foot and ankle FDs, the mean tenure in the FD position was 5.8 ± 4.6 years. Conclusions Orthopaedic foot and ankle FDs are primarily white men in their 50s, with minimal female and minority representations. These FDs are distinguished by their high level of research productivity. Additionally, orthopaedic foot and ankle training backgrounds seem to play an important role, given that most of the appointed FDs trained in only a few select programs. Clinical Relevance This study outlines some of the most important characteristics among foot and ankle FDs and identifies important disparities within this population of leaders that may have detrimental effects on the field.

Purpose To analyze the top‐100 cited articles on sports‐related concussions together with a bibliometric analysis to determine citations by year, level of evidence, study design, and several other factors related to the top referenced articles in sports concussions. Methods The Clarivate Analytics Web of Knowledge database was used to gather data using Boolean queries to capture all possible iterations of sports‐related concussion research. Articles were organized in descending order based on the number of citations and included or excluded based on relevance to concussion. Collected information included author name, publication year, country of origin, journal name, article type, study focus, and the level of evidence . Results The top‐100 articles were cited 31,197 times with an average of 312.0 citations per publication. More than one half were published in 2006 or later (52). Cohort studies and descriptive articles were the most prevalent study types (22 each). Studies with Level V evidence were the most common (33). The most common areas of study were symptomatology (short term, long term) with 17 articles, followed by epidemiology/demographics with 16 articles. The least common area of study was concussion prevention (2 articles), followed by management/treatment, diagnostics (labs, imaging) with 4 articles each. Conclusions We identified the most influential studies in sports‐related concussion based on number of citations and citation density. A majority of these articles were published in the United States after 2006 and are most commonly cohort studies (Level IV evidence) and descriptive articles (Level V evidence). Current research focuses most heavily on the symptomatology and epidemiology/demographics of sports concussion. Clinical Relevance This study serves to identify the most influential articles in sports‐related concussion and identify research topics with general deficiencies within the field of sports‐related concussion research.

Purpose To examine and characterize extremely negative Yelp reviews of orthopedic sports surgeons in the United States. Methods A search for reviews was performed using the keywords “Orthopedic Sports Medicine” on Yelp.com for 8 major metropolitan areas. Single‐star reviews were isolated for analysis, and individual complaints were then categorized as clinical or nonclinical. The reviews were classified as surgical or nonsurgical. Results A total of 11,033 reviews were surveyed. Of these, 1,045 (9.5%) were identified as 1‐star, and 289 were ultimately included in the study. These reviews encompassed 566 total complaints, 133 (23%) of which were clinical, and 433 (77%) of which were nonclinical in nature. The most common clinical complaints concerned complications (32 complaints; 6%), misdiagnosis (29 complaints; 5%), and uncontrolled pain (21 complaints; 4%). The most common nonclinical complaints concerned physicians’ bedside manner (120 complaints; 21%), unprofessional staff (98 complaints; 17%), and finances (78 complaints; 14%). Patients who had undergone surgery wrote 47 reviews that resulted in 114 complaints (20.5% of total complaints), whereas nonsurgical patients were responsible for 242 reviews and a total of 452 complaints (81.3% of total complaints). The difference in the number of complaints by patients after surgery and patients without surgery was statistically significant ( P < 0.05) for all categories except for uncontrolled pain, delay in care, bedside manner of midlevel staff, and facilities. Conclusion Our study of extremely negative Yelp reviews found that 77% of negative complaints were nonclinical in nature. The most common clinical complaints were complications, misdiagnoses and uncontrolled pain. Only 16% of 1‐star reviews were from surgical patients. Clinical Relevance Patients use online review platforms when choosing surgeons. A comprehensive understanding of factors affecting patient satisfaction and dissatisfaction is needed. The results of our study could be used to guide future quality‐improvement measures and to assist surgeons in maintaining favorable online reputations.

Abstract Purpose To determine the objective characteristics of fellowship directors (FDs) in orthopaedic sports medicine by focusing on the demographics, academic background, institutional history, research experience, and professional affiliations of FDs in this field. Methods Data was collected for each FD via institutional biographies or publicly available curriculum vitae (CV). The data collected for each FD included age, gender, race/ethnicity, previous training institutions, residency and fellowship graduation years, additional advanced degrees, military affiliation, institutional loyalty, year hired by current institution, career timeline, Scopus H‐index, number of publications, and total number of citations. Results Of the 88 FDs, 87 (98.9%) were male and 1 (1.1%) was female. The mean age for all FDs was 54.7 years (± 9.1 standard deviation). The majority of FDs were White (n = 80; 90.9%). The mean Scopus H‐index, total number of publications, and total number of citations were 22.5 ± 16.6, 90.0 ± 91.6, and 2773.9 ± 3962.9, respectively. On average, it took 9.5 ± 7.3 years from fellowship graduation until FD appointment. Additionally, the mean number of years of employment or affiliation with the current institution was 17.2 ± 9.4, and the mean number of years in an FD role was 10.9 ± 9.3. Conclusion Orthopaedic sports medicine fellowship directors are largely distinguished by their high level of research productivity and accomplishment. Additionally, orthopaedic training pedigree seems to play a role in FD role attainment, with a handful of orthopaedic residency and sports medicine fellowship programs producing a large percentage of current FDs. Finally, FDs are overwhelmingly white males with little female or minority representation. Clinical Relevance This study outlines some of the most important characteristics among orthopaedic sports medicine fellowship directors and identifies racial and gender disparities within this population of leaders that may have detrimental effects on the field as a whole.

AbstractThe National Football League Scouting Combine is an annual event held to evaluate football players. The results of the combine are used to identify talent and player potential. Our study aims to examine the relationship between combine drill performance (e.g., speed, power, agility, explosiveness) and career longevity. We performed a retrospective review of The National Football League combine test results for all defensive players from 2005–2015 to determine the association of each player’s combine test results with career longevity. The position that had the most significant associations for 1-year status was linebackers, with weight, 10-yard dash, 20-yard dash, 40-yard dash, broad jump, 3-cone drill, and shuttle being significantly associated with 1-year roster status. The position that had the most significant associations for 5-year status was cornerbacks, with weight, 10-yard dash, 20-yard dash, 40-yard dash, 3-cone drill, and shuttle being significantly associated with 1-year roster status. The least number of significant associations was found for safeties, with no drill being associated with 1-year roster status and only height and shuttle time significantly associated with 5-year career longevity. Our study demonstrates the utility of the combine results to help estimate the career longevity of NFL defensive players.

Background: While anemia has been associated with poor surgical outcomes in total knee arthroplasty and total hip arthroplasty, the effects of anemia on total ankle arthroplasty remain unknown. This study examines how preoperative anemia affects postoperative outcomes in total ankle arthroplasty. Methods: A retrospective analysis was performed using the American College of Surgeons National Surgery Quality Improvement Project database from 2011 to 2018 for total ankle arthroplasty procedures. Hematocrit (HCT) levels were used to determine preoperative anemia. Results: Of the 1028 patients included in this study, 114 patients were found to be anemic. Univariate analysis demonstrated anemia was significantly associated with an increased average hospital length of stay (2.2 vs 1.8 days, P < .008), increased rate of 30-day readmission (3.5% vs 1.1%, P = .036), increased 30-day reoperation (2.6% vs 0.4%, P = .007), extended length of stay (64% vs 49.9%, P = .004), wound complication (1.75% vs 0.11%, P = .002), and surgical site infection (2.6% vs 0.6%, P = .017). Multivariate logistic regression analysis found anemia to be significantly associated with extended hospital length of stay (odds ratio [OR], 1.62; 95% CI, 1.07-2.45; P = .023) and increased reoperation rates (OR, 5.47; 95% CI, 1.15-26.00; P = .033). Anemia was not found to be a predictor of increased readmission rates (OR, 3.13; 95% CI, 0.93-10.56; P = .066) or postoperative complications (OR, 1.27; 95% CI, 0.35-4.56; P = .71). Conclusion: This study found increasing severity of anemia to be associated with extended hospital length of stay and increased reoperation rates. Providers and patients should be aware of the increased risks of total ankle arthroplasty with preoperative anemia. Level of Evidence: Level III, retrospective comparative study.

Abstract Objective . Bioimpedance devices are commonly used to assess health parameters and track changes in body composition. However, the cross-sectional agreement between different devices has not been conclusively established. Thus, the objective of this investigation was to examine the agreement between raw bioelectrical variables (resistance, reactance, and phase angle at the 50 kHz frequency) obtained from three bioimpedance analyzers. Approach . Healthy male ( n = 76, mean ± SD; 33.8 ± 14.5 years; 83.9 ± 15.1 kg; 179.4 ± 6.9 cm) and female ( n = 103, mean ± SD; 33.4 ± 15.9 years; 65.6 ± 12.1 kg; 164.9 ± 6.4 cm) participants completed assessments using three bioimpedance devices: supine bioimpedance spectroscopy (BIS), supine single-frequency bioelectrical impedance analysis (SFBIA), and standing multi-frequency bioelectrical impedance analysis (MFBIA). Differences in raw bioelectrical variables between the devices were quantified via one-way analysis of variance for the total sample and for each sex. Equivalence testing was used to determine equivalence between methods. Main results . Significant differences in all bioelectrical variables were observed between the three devices when examining the total sample and males only. The devices appeared to exhibit slightly better agreement when analyzing female participants only. Equivalence testing using the total sample as well as males and females separately revealed that resistance and phase angle were equivalent between the supine devices (BIS, SFBIA), but not with the standing analyzer (MFBIA). Significance . The present study demonstrated disagreement between different bioimpedance analyzers for quantifying raw bioelectrical variables, with the poorest agreement between devices that employed different body positions during testing. These results suggest that researchers and clinicians should employ device-specific reference values to classify participants based on raw bioelectrical variables, such as phase angle. If reference values are needed but are unavailable for a particular bioimpedance analyzer, the set of reference values produced using the most similar analyzer and reference population should be selected.

Purpose To determine the 50 most frequently cited studies in the orthopaedic shoulder arthroscopy literature and to conduct a bibliometric analysis of these studies. Methods The Clarivate Analytics Web of Knowledge database was used to gather data and metrics using Boolean queries to capture all possible iterations of shoulder arthroscopy research. The search list was sorted so that articles were organized in descending order based on the number of citations and included or excluded based on relevance to shoulder arthroscopy. The information extracted for each article included author name, publication year, country of origin, journal name, article type, and the level of evidence. Results For these 50 studies, the total number of citations was calculated to be 13,910, with an average of 278.2 citations per paper. The most‐cited article was cited 1134 times, whereas the second‐ and third‐most cited articles were cited 920 and 745 times, respectively. All 50 articles were published in English and came from 7 different orthopaedic journals. The United States was responsible for most of the included articles (31), followed by France (9) and Japan (3). Conclusions The majority of the most‐cited articles in shoulder arthroscopy are case series and descriptive studies originating from the United States. In addition, more than one half of the top 50 most‐cited studies were published after 2004, which suggests that article age may be less important in the accumulation of citations for a rapidly growing field like shoulder arthroscopy. Clinical Relevance The top 50 most‐cited studies list will provide researchers, medical students, residents, and fellows with a foundational list of the most important and influential academic contributions to shoulder arthroscopy.
