Hip Range of Motion During Passive and 1-Leg Exercises Is Greater in Women: A Meta-analysis and Systematic Review.

PURPOSE: To summarize sex-related differences in hip range of motion (ROM), including flexion, extension, abduction, adduction, internal rotation, and external rotation. METHODS: We performed a systematic search of 3 databases (PubMed, CINAHL [Cumulative Index to Nursing and Allied Health Literature], and Embase). The search terms were as follows: hip, pelvis, range of motion, kinematic, men, and women. Included studies reported sex-specific data on hip ROM in healthy, uninjured adults. To generate hip ROM mean differences, a DerSimonian-Laird random-effects model was used. Effect sizes were pooled for each exercise. Subgroup analyses compared hip ROM by physical activity group: passive ROM, 1-leg hop or jump, 2-leg hop or jump, 2-leg drop or landing, 1-leg squat, 2-leg squat, walking, and jogging/running. Positive effect sizes represent greater ROM in women. RESULTS: Thirty-eight studies with 3,234 total subjects were included; of these subjects, 1,639 were women (50.1%). The mean age was 25.3 years. An effect difference was considered statistically significant if P < .05 and clinically significant if the mean difference was greater than 4.0°. Women showed statistically and clinically significantly greater hip flexion in passive ROM (mean difference, 6.4°) and during the 1-leg hop or jump exercise (mean difference, 6.5°). Women also showed statistically and clinically significantly greater hip adduction during the 1-leg hop or jump (mean difference, 4.5°) and 1-leg squat (mean difference, 4.4°) exercises, as well as statistically and clinically significantly greater hip internal rotation in passive ROM (mean difference, 8.2°). In contrast, men showed statistically and clinically significantly greater flexion during the 2-leg hop or jump exercise (mean difference, -9.1°). No clinically significant differences in extension, abduction, or external rotation were found between women and men. CONCLUSIONS: On average, women showed statistically and clinically significantly greater flexion, adduction, and internal rotation during passive and 1-leg exercises whereas men showed statistically and clinically significantly greater flexion during the 2-leg hop or jump exercise. LEVEL OF EVIDENCE: Level IV, meta-analysis and systematic review of Level II-IV studies.

Concomitant Tibial Tubercle Osteotomy Reduces the Risk of Revision Surgery After Medial Patellofemoral Ligament Reconstruction for the Treatment of Patellar Instability.

PURPOSE: To compare postoperative complication rates between patients who underwent medial patellofemoral ligament reconstruction (MPFLR) and those who underwent MPFLR with tibial tubercle osteotomy (TTO) in a large-scale study. A secondary goal was to investigate demographic associations with outcomes. METHODS: Patients who underwent MPFLR (n = 3,480) or MPFLR-TTO (n = 615) for patellar instability were identified in the PearlDiver database. Rates of surgery for infection, procedures for knee stiffness, patellar fracture, and revision MPFLR within 2 years postoperatively were compared using multivariable logistic regression. Demographic associations with outcomes were also investigated. RESULTS: The MPFLR-TTO cohort exhibited a significantly lower rate of revision surgery at 2 years (0.8% vs 1.9%; odds ratio [OR], 0.33; 95% confidence interval [CI], 0.10-0.80; P = .036) when compared with the MPFLR group. Independent of index procedure, patients younger than 21 years had significantly lower rates of requiring procedures for knee stiffness (OR, 0.35; 95% CI, 0.22-0.54; P < .001) and any complication at 2 years (OR, 0.59; 95% CI, 0.45-0.78; P < .001) when compared with older patients. Male patients displayed a significantly lower rate of requiring procedures for knee stiffness at 2 years than female patients (OR, 0.46; 95% CI, 0.25-0.78; P = .007). Tobacco use was associated with a significantly higher rate of postoperative infection at 2 years (OR, 2.35; 95% CI, 1.00-5.38; P = .046). CONCLUSIONS: The MPFLR cohort exhibited higher rates of revision surgery at 2 years compared with the MPFLR-TTO cohort. Patient age under 21 years was associated with lower rates of any complication and requiring procedures for knee stiffness, male sex was associated with a lower rate of requiring procedures for knee stiffness, and tobacco use was associated with a higher rate of surgery for postoperative infection. This information can assist surgeons when counseling patients before these procedures are performed. LEVEL OF EVIDENCE: Level III, retrospective, comparative prognostic trial.

WITHDRAWN:Persistent Lack of Female Orthopaedic Sports Medicine Fellows

PURPOSE: The purpose of this study was to evaluate the gender composition of fellows, faculty, and leaders within orthopaedic sports medicine fellowship programs to provide a more complete analysis of gender diversity within this subspecialty. METHODS: Official program websites of orthopaedic sports medicine fellowships listed on the Arthroscopy Association of North America (AANA) fellowship directory were examined. Data collected for analysis included the gender of program directors, fellowship faculty, orthopaedic surgery department faculty, current sports medicine fellows, and fellows who graduated within the last five years. RESULTS: Of the 132 orthopaedic sports medicine fellows in training in the United States in the 2021-2022 academic year, 113 (85.6%) were men and 19 (14.4%) were women (p<0.001). Within the past five years, 419 fellows were listed as completing a sports medicine fellowship, with 375 (89.5%) being men, and 44 (10.5%) being women (p<0.001). There was no significant difference in the gender composition of current fellows compared to the composition of fellows within the last 5 years (p=0.74). When examining gender trends in sports medicine faculty, 639 (86.6%) were men and 99 (13.4%) were women (p<0.001). There were 14 women (14.4%) orthopaedic sports medicine faculty in leadership positions (i.e., program director or assistant program director) compared to 83 men in such positions (85.6%) (p<0.001) CONCLUSIONS: Orthopaedic sports medicine fellowships remain heavily male-dominated on all levels, including fellows, faculty, and leadership. There were no differences in the gender composition of current fellows when compared to those who graduated in the last five years, suggesting persistent gender disparity and the need for novel initiatives to enhance gender diversity in sports medicine.

Evaluating Risk Factors for Biceps Tendon Injuries in Softball Players: A Systematic Review.

OBJECTIVE: Softball players commonly suffer overuse injuries due to the demands of repetitive throwing. The biceps tendon plays an important role in stabilizing the shoulder during the windmill pitch. The purpose of this study was to evaluate the measures used to identify and study biceps tendon pathology in softball players. DESIGN: This was a systematic review. SETTING: PubMed MEDLINE, Ovid MEDLINE, and EMBASE were searched. PARTICIPANTS: Studies that investigated biceps tendon injuries in softball players. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Range of motion (ROM), strength, and visual analog scale data were collected. RESULTS: Of 152 search results, 18 were included. A total of 536 of 705 athletes (76%) were softball players (average age 14-25 years). Five of 18 articles (27.7%) studied changes in external rotation with the shoulder at 90 degrees of abduction, and 4 of 18 (22.2%) studied internal rotation. Two of 18 studies (11.1%) examined ROM or strength changes in forward flexion. CONCLUSIONS: While researchers agree that the windmill pitch places significant stress on the biceps tendon, our study finds that the metrics used to evaluate shoulder pathology in these players primarily evaluate the rotator cuff without isolating the biceps tendon. Future studies should include clinical tests and biomechanical metrics more specific to identifying biceps and labral pathology (eg, strength, fatigue, and ROM in glenohumeral forward flexion, elbow flexion, and forearm supination) and attempt to clarify differences in pathology between pitchers and position players to better characterize the frequency and severity of biceps tendon pathology in softball players.

Diversity in Orthopaedic Sports Medicine Societies.

Purpose: The purpose of this study was to report demographic trends in terms of ethnicity/race and gender among the membership and leadership positions of the Arthroscopy Association of North America (AANA) and the American Orthopaedic Society of Sports Medicine (AOSSM). Over the years both AANA and AOSSM will increase in diversity through their committee membership and leadership positions. Methods: AANA and AOSSM membership and leadership were reviewed for the years 2010, 2015, and 2020. Race/ethnicity was divided into Caucasian, Asian, African American (AA), Hispanic/Latin/South American (HLSA), and Middle Eastern (ME). Gender was limited to male or female, based on name and photographic depiction. Results: Diversity in AANA and AOSSM committee and leadership positions is summarized in Table 1 and Table 2, respectively. In 2010, 166/191 (87%) AANA committee members were Caucasian, as compared with 125/186 (67%) in 2020. Asian committee members were similar in 2010 (13/191, 7%) and 2015 (13/216, 6%) but increased to 17/186 (10%) in 2020. HLSA committee members increased from 5/191 (3%) 2010 to 11/186 (6%) in 2020. AA committee membership increased from 2/191 (1%) in 2010 to 5/186 (3%) in 2020. The diversity of AANA Board of Director leadership positions increased, with Caucasian representation decreasing from 14/14 (100%) 2010 to 11/12 (92%) in 2020 and Asian representation increasing from 0% in 2010 to 1/12 (8%) in 2020, with HLSA, AA and ME remaining the same with 0/12 (0%). In AANA, men comprised 181/191 (95%) committee members in 2010 and 166/186 (89%) in 2020. The percentage of female committee members increased from 10/191 (5%) in 2010 to 20/186 (11%) in 2020. In 2010, 73/79 (92%) AOSSM committee members were Caucasian compared to 62/81 (77%) in 2020 with AA having the largest increase in committee members from 0% in 2010 to 6/81 (7%) in 2020 (Table 2). Within AOSSM, men comprised 73/79 (92%) committee members in 2010 and 70/81 (86%) in 2020. The percentage of female committee members in AOSSM increased from 6/79 (8%) in 2010 to 11/81 (14%) in 2020. Conclusion: There has been a progressive trend toward increasing diversity in both committee membership and leadership positions in AANA and AOSSM from 2010 to 2020. Within AANA, there has been a decrease in the Caucasian representation from 87% in 2010 to 67% in 2020 and an increase in the female representation from 5% in 2010 to 11% in 2020. AOSSM demonstrated a similar trend, with Caucasian representation decreasing from 92% in 2010 to 77% in 2020, in addition to female percentage increasing from 8% in 2010 to 14% in 2020. Although there has been an increase in representation of minority and female orthopaedic surgeons within both societies, there is still room for more diversity and inclusion within committee membership and leadership. It is important to progress toward the understanding of the changes that need to be made and work to implement opening the field of orthopaedic sports medicine.

Females Are More Likely Than Males to Fill an Opioid Prescription in the Year After Anterior Cruciate Ligament Reconstruction.

Purpose: To report rates of preoperative and postoperative opioid use between male and female patients and to identify risk factors for extended opioid use following anterior cruciate ligament reconstruction (ACLR). Methods: Patients undergoing ACLR between 2011 and 2018 were identified from the PearlDiver database. The opioid refill rates for males vs females were compared at monthly intervals for 1 year after ACLR. Patients who filled an opioid prescription <3 months before surgery were classified as opioid users, while those who had never filled one were classified as nonopioid users. Results: Of 106,995 ACLR patients, 37,890 (35.4%) were opioid users <3 months before surgery, and 37,554 (35.1%) had never filled an opioid prescription. Of the preoperative opioid users, 20,413 (53.9%) were female and 17,477 (46.1%) were male (P < .001). Postoperatively, females were at higher risk of filling an opioid prescription at each monthly interval, except for the first month after surgery. The refill rate for opioid users was also higher than that for nonopioid users at each monthly interval after ACLR. In addition to patient sex, a preoperative diagnosis of anxiety/depression, low back pain, myalgia, a history of drug dependence, alcohol abuse, and tobacco use increased a patient's risk of filling an opioid prescription postoperatively. Conclusions: This study demonstrated that females are significantly more likely to be opioid users than males prior to ACLR and are more likely to continue to refill an opioid prescription in the year following surgery. Multiple risk factors were associated with prolonged postoperative opioid utilization, including female sex, anxiety/depression, low back pain, myalgia, a history of drug dependence, alcohol abuse, and tobacco use. Level of Evidence: Level III, retrospective cohort study.

Doximity Orthopaedic Surgery Program Rankings Are Associated with Academic Productivity.

Doximity residency rankings are used to compare training programs. Reputation is a component of Doximity rankings and is based on physician surveys. Outcomes-based measures allow for objective program comparison and may be more appropriate when assessing programs. This study evaluated how Doximity rankings of orthopaedic surgery residency programs compare with an outcomes-based ranking of programs based on academic productivity. This study also evaluated whether program size and type were associated with academic productivity. Methods: Orthopaedic program rankings, size, type, and research productivity were recorded from Doximity. An academic productivity score was calculated by averaging the mean percentage of alumni clinical trials and alumni publications. Analysis of variance and post hoc analyses were performed to determine whether academic productivity was associated with program reputation, size, and type. Results: One hundred seventy-five orthopaedic residency programs were included. Program rankings, size, and type had a statistically significant association with academic productivity (p < 0.0001). The 44 orthopaedic programs in the top quartile had an academic productivity score of 79.1 ± 13 in comparison with programs in the bottom quartile, who had a score of 38.3 ± 12.1 (p < 0.0001). Of the programs in the top quartile of reputation rankings, 32 (73%) were also in the top quartile for academic productivity. Programs with more residents demonstrated greater academic productivity than smaller programs. Twenty-three programs (13%) had more than 30 residents and a mean academic productivity of 76.2 ± 14.8. In comparison, 13 programs (7.5%) had 10 or fewer residents with an academic productivity score of 40.6 ± 16.3 (p < 0.0001). An academic productivity score differed significantly based on program type: university (63.9 ± 14.8), military (54.7 ± 16.9), university/community (46.3 ± 15.6), and community (38.7 ± 15) (p < 0.0001). Conclusions: Academic productivity among orthopaedic residency programs is associated with Doximity ranking, program size, and type. This information can be used by medical students, residents, and physicians to understand the Doximity rankings and how they correlate with this objective measure. Level of Evidence: III.

Mentoring on Orthopedic Surgery Clinical Rotations: A Survey of Mentor Effectiveness on Student Mentees Compared to an Unmentored Control Group.

INTRODUCTION: Mentorship is an important aspect of medical education in providing students guidance and connections to new opportunities, ultimately leading to increased productivity and career satisfaction. The purpose of this study was to design and implement a formal mentoring program between medical students participating in their orthopedic surgery rotation and orthopedic residents to determine if this relationship improved students' experiences during their rotation compared to students who were not mentored. DESIGN: Third- and fourth-year medical students rotating in orthopedic surgery and PGY2-PGY5 orthopedic residents at one institution were eligible to participate in a voluntary mentoring program between the months of July and February during 2016 to 2019. Students were either randomly paired with a resident mentor (experimental group) or not (unmentored control group). Anonymous surveys were distributed to participants at weeks 1 and 4 of their rotation. There were no minimum number of meetings required between mentors and mentees. RESULTS: Twenty-seven students (18 mentored, 9 unmentored) and 12 residents completed surveys during week 1. Fifteen students (11 mentored, 4 unmentored) and 8 residents completed surveys during week 4. While both mentored and unmentored students experienced an increase in enjoyment, satisfaction, and level of comfort at week 4 compared to week 1, the unmentored group demonstrated a greater overall increase. However, from the perspective of the residents, excitement for the mentoring program and the perceived value of mentoring decreased and 1 (12.5%) resident felt that it detracted from their clinical responsibilities. CONCLUSION: While formal mentoring enhanced the experience of medical students on orthopedic surgery rotations, it did not substantially improve medical student perceptions when compared to students who did not receive formal mentoring. The greater satisfaction and enjoyment observed in the unmentored group may be explained by informal mentoring that naturally occurs among students and residents with similar interests and goals.

Persistent Lack of Female Orthopaedic Sports Medicine Fellows.

Purpose: To evaluate the gender composition of fellows, faculty, and leaders within orthopaedic sports medicine fellowship programs to provide a more complete description of gender diversity within this subspecialty. Methods: Official program websites of orthopaedic sports medicine fellowships listed on the Arthroscopy Association of North America fellowship directory were examined. Data collected for analysis included the gender of program directors, fellowship faculty, orthopaedic surgery department faculty, current sports medicine fellows, and fellows who graduated within the last 5 years. Results: Of the 132 orthopaedic sports medicine fellows in training in the United States in the 2021 to 2022 academic year, 113 (85.6%) were men and 19 (14.4%) were women (P < .001). Within the past 5 years, 419 fellows were listed as completing a sports medicine fellowship, with 375 (89.5%) being men, and 44 (10.5%) being women (P < .001). There was no significant difference in the gender composition of current fellows compared with the composition of fellows within the last 5 years (P = .74). When we examined gender trends in sports medicine faculty, 639 (86.6%) were men and 99 (13.4%) were women (P < .001). There were 14 women (14.4%) orthopaedic sports medicine faculty in leadership positions (i.e., program director or assistant program director) compared with 83 men in such positions (85.6%) (P < .001). Conclusions: Orthopaedic sports medicine fellowships remain heavily male-dominated on all levels, including fellows, faculty, and leadership. There were no differences in the gender composition of current fellows when compared with those who graduated in the last 5 years, suggesting persistent gender disparity and the need for novel initiatives to enhance gender diversity in sports medicine. Level of Evidence: IV, descriptive study.

Examining the Healthcare and Economic Burden of Gun Violence in a Major US Metropolitan City.

INTRODUCTION: The highest rates of fatal and nonfatal injury due to firearms occur in the Southern United States. This study examined the epidemiology of gunshot wound (GSW) injuries and the association of injury severity with mortality. METHODS: This is a retrospective cross-sectional analysis of 2016 to 2019 data from a mandatory reporting system for all licensed hospitals in Louisiana. Patients aged 18 years and older at the time of hospitalization for GSW were included. Injury severity was measured by the New Injury Severity Score (NISS). Primary outcomes assessed included mortality, length of stay, and total hospital charges. RESULTS: There were 1,709 firearm injuries identified. The patient sample was 83.2% Black and 87.4% male, with a mean age of 34 years. Orthopaedics was the most frequently consulted surgical service. Total hospital visit charges for all GSW-associated care were $262.4 million. The multivariable adjusted odds ratio and 95% confidence interval for mortality associated with a high NISS was 16.32 (8.96, 29.72). CONCLUSION: This study demonstrated the utility of NISS as a predictor of total hospital charges and length of stay, in addition to its well-established role as a predictor of mortality. Epidemiologic trends in GSW pathologies and associated procedures at a major urban trauma center were also reported. LEVEL OF EVIDENCE: Level III, prognostic study.

Bullying in Orthopaedic Surgery: A Survey of US Orthopaedic Trainees and Attending Surgeons.

INTRODUCTION: Bullying is a notable problem in surgery, creating a hostile environment for surgeons and trainees, and may negatively affect patient care. However, specific details regarding bullying in orthopaedic surgery are lacking. The primary aim of this study was to determine the prevalence and nature of bullying within orthopaedic surgery in the United States. METHODS: A deidentified survey was developed using the survey created by the Royal College of Australasian Surgeons and the validated Negative Acts Questionnaire-Revised survey tool. This survey was distributed to orthopaedic trainees and attending surgeons in April 2021. RESULTS: Of the 105 survey respondents, 60 (60.6%) were trainees and 39 (39.4%) were attending surgeons. Although 21 respondents (24.7%) stated they had been bullied, 16 victims (28.1%) did not seek to address this behavior. Perpetrators of bullying were most commonly male (49/71, 67.2%) and the victims' superior (36/82, 43.9%). Five bullying victims (8.8%) reported the behavior, despite 46 respondents (92.0%) stating that their institution has a specific policy against bullying. CONCLUSION: Bullying behavior occurs in orthopaedic surgery, with perpetrators being most commonly male and the victims' superiors. Despite the fact that an overwhelming majority of institutions have policies against bullying, the reporting of such behavior is lacking.

YouTube Videos Lack Efficacy as a Patient Education Tool for Rehabilitation and Return to Play Following Medial Patellofemoral Ligament Reconstruction.

Purpose: To investigate the efficacy of YouTube videos as a patient education resource related to rehabilitation and return to play following medial patellofemoral ligament (MPFL) reconstruction. Methods: YouTube was queried using 6 predetermined search terms. Videos were included if they met the following criteria: (1) written in the English language; and (2) within the first 100 videos for each search term. Videos were excluded if they met any of the following criteria: (1) not written in the English language; (2) did not include medial patellofemoral ligament/MPFL in the title; (3) duplicate videos; (4) part of a multivideo series such a vlogs; (5) advertisements; and (6) videos <1 minute. The remaining videos were evaluated by 2 independent viewers and scored using 4 distinct scoring systems: Global Quality Scale, The Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT), MPFL Rehabilitation and Return to Play Score, and the Journal of the American Medical Association benchmark criteria. The data was analyzed with IBM SPSS Statistics, version 27). The Kruskal-Wallis test was used to compare quality scores and video analytics to their assigned categories. Results where P < .05 were considered statistically significant and pairwise comparison analysis was completed to determine the video categories with statistically significant differences. Correlation of categorical variables with video analytics (views, video power index, duration, and days since publication) and quality scores was determined using the Pearson Correlation coefficient. Results: Of the initial 600 videos, 58 met inclusion criteria, which were subsequently reviewed and scored. Most videos scored on the low-end of the possible scoring ranges with a mean Global Quality Scale score of 1.61 (standard deviation [SD] 0.81), PEMAT Understandability score of 59.40 (SD 17.54), PEMAT Actionability score of 18.20 (SD 29.92), MPFL Rehabilitation and Return to Play Score of 1.64 (SD 2.13), and Journal of the American Medical Association benchmark score of 2.08 (SD 0.75). Conclusions: The videos in YouTube's library received low scores in quality, reliability, understandability and actionability. Therefore, YouTube is currently a poor source of information for patients regarding postoperative rehabilitation and return to play following MPFL reconstruction. Clinical Relevance: Patients increasingly view medical information online. YouTube is second only to Google as the most used search engine. It is important to understand the quality of information patients receive on YouTube following MPFL reconstruction so orthopaedic surgeons know to guide patients to higher-quality alternatives.

Orthopaedic Sports Medicine Podcasts Should Tailor Characteristics Such as Episode Length and Social Media Utilization for Best Audience Engagement.

Purpose: To describe the growth and characteristics of active orthopaedic sports medicine podcasts. Methods: Three common podcasting platforms (Apple, Google, and Spotify) were queried July 24, 2021 using the search term "sports medicine." For each unique active podcast hosted by an orthopaedic surgeon, data were collected on year of the first episode, number of episodes, frequency of episodes, types of guests, topics discussed, episode length, and social media presence. Descriptive characteristics were then calculated. Results: 15 podcasts met inclusion criteria. Seven (46.7%) of these podcasts were started within 12 months of July 24, 2021. The most common episode release schedule was weekly, and podcast lengths averaged 21 minutes, 47 seconds (SD 17:17, range: 11:02-1:49:13). All podcasts featured guests, most often from a variety of sports medicine backgrounds. Social media platforms were commonly used by podcast hosts, with social media account follower numbers as high as over 100,000, and consistent engagement across three major social media platforms for most podcasts. Conclusions: This study found that episodes are typically released weekly and average 21 minutes, 47 seconds long, with most covering a wide array of topics in sports medicine. The Facebook accounts of these podcasts displayed higher numbers of followers compared to other social media platforms; however, Instagram was superior for engagement. Clinical Relevance: Orthopaedic sports medicine podcasts have an increasing presence and can be used to increase trainee engagement and public exposure via tailoring of podcast episode lengths and selection of social media platforms with high audience interaction.

Acute Quadriceps Tendon Rupture: Presentation, Diagnosis, and Management.

¼: The incidence of quadriceps tendon rupture is estimated to be 1.37 cases per 100,000 people/year, with a predilection for these injuries in patients who are ≥40 years of age. ¼: Quadriceps tendon ruptures are more likely to occur in the presence of preexisting comorbidities such as rheumatoid arthritis, systemic lupus erythematosus, gout, chronic kidney disease, secondary hyperparathyroidism, diabetes mellitus, and peripheral vascular disease. The most common mechanism of injury is a simple fall. ¼: Magnetic resonance imaging is the gold-standard test for diagnosing quadriceps tendon ruptures, with a reported sensitivity, specificity, and positive predictive value of 1.0. ¼: Complete tears require prompt surgical intervention; the most common technique is transosseous sutures passed through longitudinal patellar drill holes. Suture anchors have been proposed as an alternative method; they have shown superior biomechanical results in cadaveric models. ¼: Early functional mobilization with full weight-bearing and progressive range-of-motion exercises is recommended for rehabilitation following injury.

Patient Education Materials Found via Google Search for Shoulder Arthroscopy Are Written at Too-High of a Reading Level.

Purpose: To evaluate the quality and correlation of readability on actionability and understandability of shoulder arthroscopy-related patient education materials (PEMs) found via a routine Google search. Methods: Two independent authors performed an online Google search with the term "shoulder arthroscopy." The first 5 pages of search results were then screened for PEMs. Journal articles, news articles, nontext materials, and unrelated websites were excluded. The readability of included resources was calculated using objective metrics: Flesch-Kincaid Grade Score, Simple Measure of Gobbledygook index, Coleman-Liau Index, and the Gunning Fog Index. Patient Education Material Assessment Tool for Printed Materials assessed for understandability and actionability. Associations between readability and actionability and understandability were determined using Spearman correlation and linear regression. Results: The searches returned 53 websites related to shoulder arthroscopy. A total of 34 (64%) met inclusion criteria. A high school reading level or greater was required to read the average PEM according to all scales used. The average PEM received a Patient Education Material Assessment Tool for Printed Materials score of 61.33 in understandability (range 18.75-89.47) and 55.59 points in actionability (range 16.67-83.33). An easily understood or actionable article would score at least 70 points. A moderate correlation was observed between readability and actionability on three of the scales used (r = 0.5, r = 0.59, r = 0.61). Conclusions: Most shoulder arthroscopy PEMs identified on Google are not written at a level that the average patient can read, understand, or act on (actionability). Clinical Relevance: Orthopaedic surgeons should be aware of the resources that patients use to obtain medical information. More accessible PEMs should be developed for patients undergoing shoulder arthroscopy to enhance comprehension of their condition and improve shared decision-making.

Positive Association Between Online Attention and the Bibliometric Impact of Shoulder Instability Publications.

Purpose: To obtain a quantifiable measure of the frequency with which a shoulder instability article is discussed online and the association with its corresponding bibliometric impact, based on the Scopus Cite Score (SCS) or Web of Science Impact Factor (WSIF). Methods: The top 100 most-mentioned articles on shoulder instability based on Altmetric Attention Score (AAS) were extracted from the Altmetric Database. Mentions within blogs, news articles and outlets, public policy, and social media platforms, such as Twitter and Facebook, were included. Study impact was assessed using SCS or WSIF. The degree of association between AAS and impact was determined using Spearman correlation, logarithmic regression, and multivariate regression. Results: The most common study designs were "Clinical Trial," with 52 articles (49.5%), "Systematic Review" with 16 articles (15.2%), and "Review" with 10 articles (9.5%). Twitter provided more online mentions than other platforms, with the average article being discussed 27.7 times (range 0-220 times). A significant positive effect (estimate = 2.616, P = .0075) was observed between the AAS and WSIF, based on the logarithmic regression. Multivariate regression revealed that blogs help raise both WSIF and SCS (estimate = 7.272, P < .05). Conclusions: Social media and other online platforms are a strong way to disseminate information to patients. A positive association was observed between overall online attention and the bibliometric impact of an article related to shoulder instability. Clinical trials related to shoulder instability that receive online mentions, especially discussion in blogs, are more likely to be cited in the future than their counterparts. Clinical Relevance: The results of our study can guide authors as they aim to disseminate their articles. Twitter may be used as a tool to reach patients who may not venture into academic journals with current peer-reviewed articles. Further, blogs may be used to reach academic audiences and raise bibliometric impact broadly.

The Top 50 Articles on Knee Posterolateral Corner Injuries.

Purpose: To identify and characterize the most cited publications in orthopaedic research related to posterolateral corner (PLC) injuries of the knee. Methods: The Science Citation Index Expanded was queried for PLC injury articles. The 50 most-cited studies from 1976 to 2021 were selected. Article characteristics, including number of citations, citation density, year of publication, source journal, country of origin, article type, article subtype, and level of evidence, were analyzed. Results: The number of citations for individual articles ranged from 47 to 205. The 50 most cited articles were published in 16 journals. Eleven of the 50 articles (22%) were published in Arthroscopy-The Journal of Arthroscopic and Related Surgery. The largest proportion of the articles (n = 22, 44%) were classified as clinical, with the rest classified as reviews (n = 15, 30%), and basic science research (n = 13, 26%). The most common level of evidence for clinical articles was IV (14/22, 63.6%). Nine countries contributed to the top 50 articles, with the majority published in the United States (n = 35, 70%). Conclusions: In the last 20 years, papers published on the diagnosis and surgical management of PLC injuries have a high citation frequency. Future high-quality research is needed to establish best-practice guidelines for the management of PLC injuries due to the low overall level of evidence of existing clinical studies. Clinical Relevance: This research provides a comprehensive list for practitioners and may help educators identify articles to include in the curriculum for residents and fellows.
