ABSTRACT Objective: To identify the 100 top-cited articles published in orthodontics journals and to analyze their characteristics to investigate the achievement and development of orthodontics research in past decades. Methods and Materials: The Institute for Scientific Information Web of Knowledge Database and the 2011 Journal Citation Report Science Editions were used to retrieve the 100 top-cited articles published in orthodontics journals since 1975. Some basic information was collected by the Analyze Tool on the Web of Science, including citation time, publication title, journal name, publication year, and country and institution of origin. A further study was then performed to determine authorship, article type, field of study, study design, and level of evidence. Results: The 100 target articles were retrieved from three journals: American Journal of Orthodontics and Dentofacial Orthopedics (n  =  74), The Angle Orthodontist (n = 15), and European Journal of Orthodontics (n  =  11). Since 1975, the articles cited 89 to 545 times mainly originated from the United States, and the overwhelming majority of articles were clinical. The most common study design was case series; 40 articles were classified as level IV and 12 as level V evidence. Conclusions: The 100 top-cited articles in orthodontics are generally old articles, rarely possessing high-level evidence.

Background: Osteoarthritis is a degenerative disease that commonly occurs in middle-aged and elderly people. High-quality articles in the field of osteoarthritis rehabilitation have not been studied in detail. Objective: To identify and conduct a qualitative and quantitative analysis of the 50 most-cited articles on osteoarthritis rehabilitation and provide valuable scientific information for researchers. Methods: Fifty articles related to the rehabilitation of individuals with osteoarthritis were retrieved from the Web of Science Core Collection. Basic information, such as the authors, title, number of citations, year of publication, journal, country/territory, and research type, was extracted. CiteSpace was used to visualize the keywords. Results: The average number of citations per article was 244.54. The top 50 articles were published in 27 journals and published by 262 authors. Most of the top 50 articles were published in the United States. The top 50 articles included 23 randomized controlled trials, 21 cohort studies, 2 case series, and 4 expert opinion articles. The most commonly studied topics in osteoarthritis rehabilitation included rehabilitation for pain, gait abnormalities, muscle strength deficiencies, and other functional impairments caused by osteoarthritis in elderly people. Conclusions: The top articles in the field of osteoarthritis rehabilitation have a high level of evidence. Collaboration between authors was high for highly-cited articles. Moreover, the eminent articles can provide important information for the education of doctors and therapists specializing in osteoarthritis rehabilitation.

Study Designs

Background: Observational studies are the most commonly employed study designs in the pediatric orthopaedic literature. The differences between observational study designs are important but not widely understood, leading to potential discrepancies between the reported and actual study design. Study design misclassification is associated with a potential for misreporting level of evidence (LOE). Purpose: To determine the degree of study design and LOE misclassification in the pediatric orthopaedic literature. Methods: The Institute for Scientific Information (ISI) Web of Science was queried to identify all pediatric orthopaedic observational studies published from 2014-2017. Reported study design and LOE were recorded for each study. The actual study design and LOE were determined based on established clinical epidemiological criteria by reviewers with advanced epidemiological training. Studies with a discrepancy between reported and actual study design and LOE were identified. The following covariates were recorded for each study: subspecialty, inclusion of a statistician coauthor, sample size, journal, and journal impact factor. Chi-square analysis was used to identify factors associated with study design and LOE misreporting. Results: One thousand articles were screened, yielding 647 observational studies. Three hundred thirty-five publications (52%) did not clearly report a study design in either the abstract or manuscript text. Of those that did, 59/312 (19%) reported the incorrect study design (Figure 1). The largest discrepancy was in the 109 studies that were reported to be case series, among which 30 (27.5%) were actually retrospective cohort studies. Three hundred thirteen publications (48%) did not report a LOE. Of those that did, 95/334 (28%) reported the incorrect LOE (Figure 2). Thirty-three studies (19%) reported a LOE that was higher than the actual LOE and 62 (35%) under-reported the LOE. Conclusion: The majority of observational pediatric orthopaedic studies either did not report a study design or reported the wrong study design. Similarly, the majority of studies did not report or misreported their LOE. Greater epidemiological rigor in classifying and evaluating observational studies is required on the part of investigators, reviewers, and journal editors. [Figure: see text][Figure: see text]

Category: Ankle Arthritis Introduction/Purpose: Total ankle arthroplasty (TAA) is gaining popularity as an alternative to ankle arthrodesis in the setting of end-stage ankle arthritis. However, compared to hip and knee arthroplasty, there is a relative dearth of evidence to support its use. This study assesses the quality of literature surrounding modern TAA designs. Methods: A search of all peer-reviewed, English-language journals was conducted to identify publications involving TAA. The initial search identified 444 articles published during 2006-2016. Of these, 182 were excluded because they were not clinical outcomes studies, 46 because the TAA implant was no longer available, and 15 because the primary outcome of the study was not related to TAA, leaving 201 articles for analysis. Results: No Level I studies were identified. Seventeen (8%) studies were Level II, 48 (24%) Level III, 128 (64%) Level IV, and 8 (4%) Level V. One hundred forty-three studies (71%) were retrospective in nature. Stratification by study design revealed 128 (64%) case series, 33 (16%) experimental cohort studies, 19 (10%) case-control studies, 13 (6%) observational cohort studies, and 8 (4%) case reports. The number of studies published each year steadily increased from 2006 to 2016. A total of 51% of TAA research was published in only two journals: Foot and Ankle International and the Journal of Bone and Joint Surgery. Publications from the United States accounted for 36% of total publications. The most published implant was the Scandinavian Total Ankle Replacement (Figure 1). Conclusion: While the number of TAA studies published each year has steadily increased since 2006, the quality of this research as measured by level of evidence remains suboptimal. This analysis highlights the need for continued improvement in methodology and development of robust prospective registries to advance our knowledge of TAA as a treatment for end-stage ankle arthritis.

AbstractHip resection arthroplasty (HRA) is a relatively uncommon, yet viable surgical procedure originally developed by Girdlestone for osteomyelitis of the proximal femur. Currently, HRA is primarily indicated as a salvage procedure after a failed total hip arthroplasty. Despite a continuous rise in the rates of primary and revision hip arthroplasty, there is a lack of published evidence regarding the extent of HRA's current use and its recent trends. We sought to provide an epidemiological description of the recent utilization patterns of HRA in the United States. A level of evidence IV, retrospective case series review of the entire Medicare files between 2005 and 2012 was conducted through the use of current procedural terminology codes and International Classification of Disease ninth edition codes. Linear regressions and chi-square tests were used for analysis. Subgroup analysis was performed by patient age. The total number of HRAs performed between 2005 and 2012 significantly decreased from 4,248 to 3,872 (p = 0.025). There was a significant increase in the annual incidence of HRA among patients younger than 65 years (p = 0.027; 9% increase) and patients 65 to 69 years old (p = 0.007; 22% increase), constituting 43% of the total patients. There was a significant decrease in HRA incidence among patients 80 to 84 years old (p = 0.001; 32% decrease) and patients 85 years old and over (p = 0.002; 24% decrease). Geographic analysis demonstrated the most HRA procedures were performed in the South, whereas gender focused analysis demonstrated a statistically significant decrease in HRA incidence for females (p = 0.003; 6% decrease) and a significant increase in incidence for males (p = 0.003; 7% increase). The overall annual incidence of HRA performed in the Medicare patient population has significantly decreased in recent years. However, this conceals an increased incidence among the relatively younger patient population. Potential causes for these opposing trends include changes in rates of revision surgery, alternative indications for surgery, advances in hardware, and surgeon expertise. This was a level of evidence IV, retrospective case series study.

ABSTRACT Introduction The squat is an exercise that is widely used for the development of strength in sports. However, considering that not all sports gestures are vertical, it is important to investigate the effectiveness of propulsive force stimuli applied in different planes. Objective The main purpose of this study was to determine the influence of maximum isometric force (MIF) exerted on starting blocks over performance in 5, 10 and 20-meter sprints. Methods Seven high-level male sprinters (mean age ± SD = 28 ± 5.77 years) participated in this study. The variables were: a) MIF in squats and on starting blocks (measured using a functional electromechanical dynamometer [FEMD]), b) time in 5, 10 and 20-m sprints and c) jump height (measured by the squat jump test). For data analysis, a Pearson correlation was performed between the different variables. The criteria for interpreting the strength of the r coefficients were as follows: trivial (<0.1), small (0.1−0.3), moderate (0.3−0.5), high (0.5−0.7), very high (0.7−0.9), or practically perfect (>0.9). The level of significance was p < 0.05. Results There was very high correlation between MIF exerted on starting blocks and performance in the first meters of the sprint (5-m: r = -0.84, p = 0.01). However, there was small correlation between MIF in squats and performance in the first meters of the sprint (5-m: r = -0.22, p < 0.62). Conclusion The MIF applied on starting blocks correlates very high with time in the first meters of the sprint in high-level athletes. In addition, the use of the FEMD provides a wide range of possibilities for evaluation and development of strength with a controlled natural movement.

The Impact

Background: Cheerleading is a specialized athletic activity that can lead to catastrophic injuries. Cheerleading rules are in place to maximize safety of participants. The purpose of this study was to describe catastrophic cheerleading injuries among high school and collegiate-level participants in the United States and to explore whether the 2006-2007 basket toss rule change was effective at reducing the number of catastrophic injuries. Hypothesis: The 2006-2007 basket toss rule change contributed to a reduction in the number of catastrophic injuries among high school and collegiate cheerleaders. Study Design: Case series. Level of Evidence: Level 4. Methods: Data on catastrophic cheerleading injuries were collected by the National Center for Catastrophic Sport Injury Research from July 2002 to June 2017. Information collected included cheerleader, event, and injury characteristics. The impact of the 2006-2007 rule change banning the basket toss on any hard surfaces was assessed by comparing injury rates and 95% CIs before and after the rule change. Results: There were 54 catastrophic cheerleading injuries, or 3.6 injuries per year. From July 2002 through June 2017, the injury rate was 2.12 per 1,000,000 cheerleaders (95% CI, 1.56-2.69). Most cheerleaders sustained serious injuries (n = 27; 50%) during practice (n = 37; 69%) to the head (n = 28; 52%) and cervical spine (n = 17; 32%). From July 2002 through June 2017, basket tosses were the stunt that accounted for the highest proportion of injuries (n = 19; 35%). The basket toss injury rate decreased from 1.55 to 0.40 per 1,000,000 cheerleaders among both high school and collegiate cheerleaders after the rule change. Conclusion: Catastrophic injury rates in cheerleading decreased dramatically after the 2006-2007 rule change banning basket tosses from being performed on any hard surfaces. In particular, there was a nearly 4-fold reduction in the rate of catastrophic basket toss injuries.

Background: Limited intermediate and no real long-term follow-up data have been published for total ankle arthroplasty (TAA) in the United States. This is a report of clinical follow-up data of a prospective, consecutive cohort of patients who underwent TAA by a single surgeon from 1999 to 2013 with the Scandinavian Total Ankle Replacement (STAR) prosthesis. Methods: Patients undergoing TAA at a single US institution were enrolled into a prospective study. These patients were followed at regular intervals with history, physical examination, and radiographs; American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Scale scores were obtained and recorded. Primary outcomes included implant survivability and functional outcomes scores. Secondary outcomes included perioperative complications such as periprosthetic or polyethylene fracture. Between 1999 and 2013, a total of 138 STAR TAAs were performed in 131 patients; 81 patients were female. The mean age at surgery was 61.5 ± 12.3 years (range, 30-88 years). The mean duration of follow-up for living patients who retained both initial components at final follow-up was 8.8±4.3 years (range 2-16.9 years). Results: The mean change in AOFAS Ankle-Hindfoot scores from preoperative to final follow-up was 36.0 ± 16.8 ( P < .0001). There were 21 (15.2%) implant failures that occurred at a mean 4.9 ± 4.5 years postoperation. Ten polyethylene components in 9 TAAs (6.5%) required replacement for fracture at an average 8.9 ± 3.3 years postoperatively. Fourteen patients died with their initial implants in place. Conclusion: This cohort of patients with true intermediate follow-up after TAA with the STAR prosthesis had acceptable implant survival, maintenance of improved patient-reported outcome scores, and low major complication rates. Level of Evidence: Level IV, case series.

Number Of Citations

AbstractThe number of times an article has been cited is thought to correspond with its level of academic influence. Within the orthopaedic literature, several citation analyses have been performed, including a recent investigation on the most commonly cited articles on femoroacetabular impingement (FAI); however, no study has determined the most cited investigations on extracapsular hip pathologies, including osteitis pubis, athletic pubalgia, and muscle strains. Such pathologies constitute a significant proportion of lower extremity injuries among athletes. The purpose of this study was to determine the 50 most cited investigations on extra-articular hip injuries by performing a systematic query of the Institute for Scientific Information (ISI) Web of Science (Thomson Reuters, Philadelphia, PA). The following characteristics were determined for each article: number of citations, citation density, journal and publication year, country of origin, language, article type, article subtype, and level of evidence. The number of citations ranged from 46 to 202 (mean 84.4), and the citation densities ranged from 1.7 to 28.4 citations per year (mean: 7.9). Sixty-eight percent of the selected articles involved hamstring strains. The majority of articles were published in the American Journal of Sports Medicine (58%), followed by the Journal of Orthopaedic and Sports Physical Therapy (12%). Most articles were published during the 2000s, originated from the United States, and 100% were written in English. Eighty percent were clinical studies; the majority of which had Level IV evidence. This collection of academic investigations on athletic extra-articular hip injuries can aid in the establishment of a reading curriculum for trainees participating in orthopaedic training programs.

Background: The aim of this study was to determine the early outcomes and complications following the implantation of a hydrogel synthetic cartilage implant (SCI, Cartiva) for the treatment of hallux rigidus by a single surgeon. Methods: A retrospective chart review was performed of consecutive patients who underwent treatment for hallux rigidus with an SCI between August 2016 and April 2018 by a single surgeon. Demographic information, radiographic assessment, and concomitant operative procedures performed were evaluated for all patients. Postoperatively, PROMIS physical function (PF) and pain interference (PI) scores, patient satisfaction, reoperation, conversion to arthrodesis, and need for further clinical treatment were collected. Sixty-four SCIs were implanted in 60 patients. Follow-up averaged 18.5 months (range 12-30 months). Results: 14% (9/64) of patients were very satisfied, 28% (18/64) satisfied, 20% (13/64) neutral, 11% (7/64) unsatisfied, and 27% (17/64) very unsatisfied with their outcome. In addition, 45% of patients underwent additional procedures at the time of SCI, and 23% had a history of surgery on the hallux before implantation. PROMIS PF scores averaged 42 and PROMIS PI scores averaged 60. Overall, 63% completed PROMIS PI, 66% completed PROMIS PF, and 100% completed a satisfaction survey. In addition, 30% (19/64) underwent magnetic resonance imaging (MRI) postoperatively due to pain. There was a 20% reoperation rate, which included an 8% rate of conversion to arthrodesis. Conclusion: Synthetic cartilage implantation yielded neutral patient satisfaction, mild pain, and physical dysfunction at early follow-up. We believe patient selection and counseling regarding early postoperative limitations are important before proceeding with SCI. Level of Evidence: Level IV, case series.
