To investigate the characteristics of shoulder and elbow fellowship directors (FDs).FDs for shoulder and elbow fellowship programs in the United States were identified. Demographic, educational, and professional background data were collected from available curricula vitarum, institutional biographies, and the Scopus database. Data collected included age, sex, race/ethnicity, training locations, graduation years, advanced degrees, current institutional information, and personal research H-index.Thirty current orthopaedic shoulder and elbow FDs were identified. The mean Scopus H-index was 25.5. The mean age of FDs was 52.1 years. In total, 29 FDs (96.7%) were male and 1 (3.3%) was female. In addition, 25 of the 30 (83.3%) were White (83.3%), 4 were Asian, and 1 (3.3%) was Hispanic. Two (6.7%) had a military affiliation. Mean time from fellowship training graduation to FD appointment was 13.5 years. Mean number of years as FD was 6.1 years, whereas the number of years tenure with an FD-affiliated institution was 13.0 years. Mean calendar years for completion of orthopaedic residency training and fellowship training were 1998 and 2000, respectively. The residencies that produced the most future FDs were Hospital of the University of Pennsylvania (n = 2) and University of Nebraska Medical Center/Creighton University Health Foundation (n = 2). The fellowship that produced the most future FDs was Columbia University (n = 6). Moderate correlation was found between age and Scopus H-index (r = 0.48;Women and minorities are under-represented in leadership positions in shoulder and elbow surgery. Shoulder and elbow FDs have the highest H-index of any subspecialty reported in the orthopaedic literature. Research productivity is an important qualification when considering the characteristics of shoulder and elbow FDs.Fellowship directors can have a profound influence on current and future orthopaedic surgeons. It is important to identify the traits that characterize current fellowship directors to have a better understanding of who we choose as leaders in our field.

Background The incidence of orthopedic disorders amongst patients with Prader–Willi Syndrome (PWS) is high when compared to the general pediatric population. The purpose of this retrospective study was to define the most commonly performed orthopedic procedures in pediatric patients with PWS and to characterize the peri-operative outcomes of these patients. Methods The Kids Inpatient Database (KID) was queried to collect data and identify all pediatric patients with PWS who underwent orthopedic procedures from 2001 to 2012. A total of 3684 patients with PWS were identified, 334 of who underwent an orthopedic procedure. Population demographics, comorbidities, and specific procedures undergone were defined. The incidences of postoperative complications and length of associated hospital stay were additionally evaluated. Results Mean age of patients in this sample was 10.33 years (SD 4.5). The most common comorbidities included obesity (18.1%), chronic pulmonary disease (14.1%), hypothyroidism (5.1%), hypertension (5.1%), and uncomplicated diabetes (4%). Common procedures were spinal fusion (165/334, 49%) and lower extremity procedures (50/334, 15%). Complications included acute blood loss anemia, device related complications, pneumonia, sepsis, and urinary tract infections. The overall complication rate was 35.6%. Average hospital lengths of stay for patients undergoing spinal fusion was 6.68 days (SD 4.13), lower extremity orthopedic procedure was 5.65 days (SD 7.4), and all other orthopedic procedures was 7.74 days (SD 16.3). Conclusions Orthopedic disorders are common in patients with PWS. Consequently, spinal fusions and lower extremity procedures are commonly performed in this patient population. Associated comorbid conditions may negatively impact surgical outcomes in these patients. This information should prove useful in the peri-operative management of patients with PWS undergoing orthopedic surgery and for shared decision making with families.

To use the National Collegiate Athletic Association Injury Surveillance Program (NCAA-ISP) from the 2009-2010 through the 2014-2015 seasons to report lumbar spine injury rates, characteristics, and time lost from sport in soccer players.Characteristics of lumbar spine injuries by season, competition/practice, and time lost from sport were determined using the NCAA-ISP database. Rates of injury were calculated as the number of injuries divided by the number of athlete exposures (AEs). AEs are any athlete participation in a competition or practice. Incidence rate ratios (IRRs) were calculated to compare rates between event types and time of season. Injury proportion ratios (IPRs) were used to evaluate differences in injury rates between men and women.The NCAA-ISP estimated 4,464 LSIs over 5 years. The rate of LSI in men was 2.1/10,000 AEs and 3.0/10,000 AEs in women. Women were 1.43 times more likely to suffer an LSI compared to men. Women were 2.15 times as likely to suffer an LSI in competition compared to in practice while men were 1.10 times as likely. Women were 2.15 times as likely to be injured in the preseason compared to the regular season, while men were 3.76 times as likely. Non-contact injuries were the most common cause of lumbar spine injuries (LSIs) in men (35%); however, contact injuries were more common in women (33%). Most athletes both male (57%) and female (59%) returned to play within 24 hours.This study provides information on the characteristics of LSIs in NCAA soccer. The overall injury rate to the lumbar spine is relatively low. Injury rates are highest in the preseason and in competition. Women suffer from more recurrent LSI's than men, and men acquired more injuries through non-contact mechanisms. More than one-half of athletes returned to sport within 24 hours.

Background: The development of Achilles tendon treatment modalities has been rapid, and it is increasingly difficult for clinicians to stay up to date with the most influential studies in this field. In order to fully understand the current state of the literature regarding Achilles tendon injury, it is invaluable to be familiar with the foundational articles and studies upon which the field is built. Purpose: To objectively determine the 50 most frequently cited studies in Achilles tendon pathology and to conduct a bibliometric analysis. Study Design: Cross-sectional study. Methods: The Clarivate Analytics Web of Knowledge database was used to gather data and metrics of Achilles tendon research. The 50 most cited articles were selected for analysis from an initial 17,244 identified articles. The information extracted for each article included author name, publication year, country of origin, journal name, study type, and level of evidence. Results: For these 50 studies, the total number of citations was calculated to be 13,159, with a mean of 263.2 citations per paper. The most cited article collected 657 citations. The publication dates of the 50 studies included in this analysis spanned 41 years (1972-2013). The largest number of articles were published by Swedish authors (n = 14); however, many other countries were represented, including Canada and Finland (n = 6 articles each). The most prevalent study designs were cohort studies (n = 13) with level 4 evidence studies being the most common (n = 14). Conclusion: Among the 50 most influential articles in Achilles tendon pathology, the study designs most commonly used were cohort studies and review articles. Sweden was the country of origin for the most studies included on this list, which reflects this country’s interest and commitment to researching Achilles tendon injuries and treatments.

The purpose of this study was to compare the 5-year clinical and functional outcomes of the soft tissue quadriceps tendon (QT) to those of the hamstring tendon (HT) autograft METHODS: A retrospective review of patients undergoing ACL reconstruction using either soft tissue QT or double tendon HT autograft with at least 5 years of follow up was conducted. Surgical technique included anteromedial portal creation for the femoral tunnel and transtibial technique for the tibia. Graft fixation was achieved with interference composite screws for the QT and combination of interference composite screw and suture button for the HT cohort. The two groups were compared for differences in outcomes including International Knee Documentation Committee (IKDC) score, Lysholm score, return to sport, and complications.A total of 37 patients with QT autograft and 46 HT autografts were included in the study with a mean follow up of 69.9 months and 70.9 months, respectively. The QT group demonstrated a larger graft size on average (9.64mm vs. 7.90mm, p0.001). The IKDC and Lysholm scores were similar between the two groups at 2-years postoperatively. At 5-years postoperatively, the QT group demonstrated significantly greater IKDC (p 0.018) and Lysholm (p 0.007) scores. The cohorts demonstrated similar rates of achieving minimal clinically important difference (MCID) thresholds at both 2 and 5 years postoperatively. The two groups also demonstrated comparable rates of return to sport, time to return, and postoperative complications.Although the QT autograft demonstrated increased patient reported outcome scores when compared to the HT at 5-years postoperatively, there was no clinically significant difference between the cohorts at 2 or 5 years postoperatively. The QT autograft is an effective alternative to HT autograft with non-inferior results to the hamstring autograft at mid-term follow up.Retrospective Comparison Study; Level of Evidence III LEVEL OF EVIDENCE: III, retrospective cohort study.

The purpose of this study was to determine the objective characteristics of orthopaedic musculoskeletal oncology fellowship directors (FDs) by concentrating on the demographics, academic background, institutional history, research experience, and professional affiliations of these leaders.Data were collected for each FD through institutional biographies or publicly available curriculum vitae. The data collected for each FD included demographic, professional, and research information.Of the 19 FDs, 15 (78.9%) were male, and 4 (21.1%) were female. The mean age for all FDs was 49.2 ± 9.1 years. Most FDs were White (n = 16; 84.2%). The mean Scopus H-index, total number of citations, and total number of publications among all 19 FDs were 21.6 ± 13.8, 2,290.6 ± 2,709.0, and 84.0 ± 54.7, respectively. The mean number of years serving in the FD role was 7.1 ± 9.1 years, and the mean number of years that the FD was employed at his/her current institution was 11.1 ± 8.1 years.This study shows that orthopaedic musculoskeletal oncology FDs were mainly White (84.2%), male (78.9%), and in their late 40s; have filled their role as FD for an average of 7.1 years; and are very productive in research.

Purpose: To describe and compare the epidemiology of lumbar spine injuries (LSIs) in women’s and men’s ice hockey during the 2009-2010 to 2013-2014 academic years and to investigate sex-specific differences, using data from the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP) database. Methods: The incidence and characteristics of LSIs were identified utilizing the NCAA ISP. Rates of injury were calculated as number of injuries divided by total number of athlete exposures (AEs). AEs were defined as any student participation in one NCAA-sanctioned practice or competition. Incidence rate ratios (IRRs) were calculated to compare rates of injury between season, event type, mechanism, injury recurrence, and time lost from sport, and injury proportion ratios (IPRs) were calculated to examine the differences in injury rates between men and women. Results: There were a total of 165 LSIs from an average of 10 and 19 women’s and men’s teams, respectively, calculated to 1,254 LSIs nationally. Women were 2.48 times more likely to suffer a noncontact injury than men (95% CI: 1.33-4.61), whereas men were more likely than women to suffer contact LSIs (IPR: .51 [95% CI: .28-.92]). In Divisions II and III, women were 6.64 (95% CI: 4.14-10.64) and 1.28 (95% CI: 1.12-1.46) times more likely to suffer LSIs than men, respectively. Conclusions: Women and men were similarly likely to suffer an LSI, but sex-specific differences existed in a mechanism of injury and likelihood of injury within NCAA Divisions.

Background:In patients with femoroacetabular impingement, preoperative diagnostic injections are commonly used to establish a diagnosis of intra-articular pathology. In some cases, intra-articular steroid injections are also used for therapeutic purposes.Purpose/Hypothesis:The purpose of this study was to determine if a positive response to intra-articular steroid injection was predictive of superior outcomes after hip arthroscopy to determine if the response to intra-articular steroid injection was predictive of outcomes after hip arthroscopy. It was hypothesized that a positive response to a preoperative hip injection would be predictive of improved short- to midterm outcomes after hip arthroscopy.Study Design:Cohort study; Level of evidence, 3.Methods:This was a retrospective study of 208 patients who elected to have ultrasound-guided intra-articular steroid injection before they underwent hip arthroscopy between January 2016 and December 2016. Patients were divided into 2 groups: those who showed improvement in pain after the injection (steroid responder group) and those who showed no response (nonresponder group). The authors compared the preoperative and 2-year postoperative patient-reported outcomes (modified Harris Hip Score [mHHS] and Hip Outcome Score–Activities of Daily Living [HOS-ADL]) and radiographic findings between groups. Clinical endpoints, including rates of revision and conversion to total hip arthroplasty, were also reviewed.Results:There were 88 patients in the nonresponder group and 120 patients in the responder group, with no significant between-group differences in preoperative descriptive variables. The responder group had significantly higher 2-year mHHS and HOS-ADL, pre- to postoperative change in mHHS and HOS-ADL, percentage of patients achieving the patient acceptable symptomatic state (PASS) on the mHHS, and percentage of patients reaching the minimum clinically important difference and the PASS on the HOS-ADL. There was no difference in Tönnis grade, acetabular labrum articular disruption grade, revision rate, or conversion to total hip arthroplasty between the 2 groups.Conclusion:The response to preoperative intra-articular injection did aid in predicting 2-year patient-reported outcomes of hip arthroscopy for femoroacetabular impingement. Overall, the result of a preoperative intra-articular injection can be a helpful clinical tool for surgical decision-making and counseling patients on expected outcomes after hip arthroscopy.

Background: Bibliometric citation analyses have been widely used in medicine to help researchers gain foundational knowledge about a topic and identify subtopics of popular interest for further investigations. There is a lack of similar research in collegiate athletics. Purpose: To identify the 100 most-cited research publications related to collegiate athletics. Study Design: Cross-sectional study. Methods: The Clarivate Analytics Web of Knowledge database was used to generate a list of articles relating to collegiate athletics on January 24, 2022. Articles were filtered by the total number of citations, and the 100 most-cited articles were selected. For each article, we identified and analyzed the following: author name, publication year, country of origin, journal name, article type, main research topic area, competitive level, sex of study population, and level of evidence. Results: Of the top 100 most-cited articles, 63 were related to medicine. In total, 96% of articles were published in the United States, and 80% were published in the year 2000 or later. Of the top 100 articles, 85 were observational; only 5 were experimental. The sport most represented was soccer, followed by football, baseball, and basketball. Of the top 100 articles, 21 were published in a single journal, the American Journal of Sports Medicine. Ten authors published ≥5 of the top 100 most-cited studies. Conclusion: The majority of top 100 articles were published in the United States after 1999 and primarily focused on medicine-related topics. Soccer was studied by more articles than football, baseball, and basketball. An author’s prestige may have influenced the likelihood of citation. The top 100 most-cited studies provide researchers, medical students, residents, and fellows with a foundational list of the most important and influential academic contributions to the literature on collegiate athletics.
