Purpose To quantify and analyze public interest trends in platelet‐rich plasma (PRP) therapy for shoulder pathology between 2011 and 2020 using Google Trends data. Methods Google Trends data were queried for online search data ranging from January 2011 to December 2020. Various combinations of terms related to PRP and shoulder pathology were queried. Terms related to corticosteroid therapy in association with shoulder pathology were also generated for comparative analysis. Analyses were performed regarding trends in online search volumes. Results Linear models were generated to evaluated trends in the volume of online searches for PRP and corticosteroid therapy for shoulder pathology. For both the PRP and steroid groups, linear models showed a statistically significant increase in search volume for the period studied ( P < .001). The PRP group showed a significantly greater growth rate than the steroid group ( P < .001). There were no statistically significant differences in online search volume when compared between different geographic and socioeconomic locations. Conclusions This study indicates consistently increasing public interest in PRP injections in the shoulder. The rate of online search volume growth of PRP is significantly greater than that of corticosteroid injections for the period studied. Clinical Relevance Awareness of patient perceptions has value in informing shared decision making, aligning patient expectations, and guiding areas of future research. Each of these has an impact on patient care. Being aware of patient interest and expectations is particularly important in areas with controversial or emerging research.

Background: The increased focus on patient satisfaction has led to growth in the use of physician rating websites. Purpose: To analyze the factors associated with online 5-star patient reviews for orthopaedic sports medicine surgeons. Study Design: Cross-sectional study. Methods: A total of 70 orthopaedic sports medicine surgeons were randomly selected from the AOSSM website. A search was performed for these surgeons on Yelp.com. All reviews other than 5 stars (of a possible 5 stars) were excluded from the study. Each review was categorized as referring to a surgical or nonsurgical aspect of care, and each comment within the review was categorized as being clinically or nonclinically related. Comments were further subcategorized by specific features such as bedside manner, clinical outcomes, and patient education. Categorical variables were analyzed using the chi-square test. Results: Overall, 400 five-star reviews were included in the study, comprising 1225 total positive comments. Of the 400 five-star reviews, 200 (50%) were from surgically treated patients, and 200 (50%) were from nonsurgically treated patients. Of the 1225 positive comments, 505 (41%) were clinically related, and 720 (59%) were nonclinical. The most common positive clinical comments were for clear treatment plans (191 reviews [48%]), good outcomes (173 reviews [43%]), and providing alternative treatment plans (55 reviews [14%]). The most common positive nonclinical comments were for good physician bedside manner (287 reviews [72%]), friendly/professional staff (194 reviews [49%]), and ease of scheduling (68 reviews [17%]). Conclusion: The majority of 5-star patient reviews left positive comments regarding nonclinical aspects of care such as physician bedside manner and friendly staff. The most common positive comments regarding clinical aspects concerned good outcomes and clear treatment plans. The overall most common positive comment, in both surgically and nonsurgically treated patients, referred to good bedside manner.

Background: There is a wide range of literature on patellar tendon injury, making it increasingly difficult to stay informed on the most influential studies in this field. It is essential to be familiar with the foundational articles of patellar tendon injury research to understand the current state of the literature and deliver high quality care. Purpose: To objectively identify the 50 most influential articles relating to patellar tendon injury and conduct a bibliometric analysis to identify key features of these articles. Study Design: Cross-sectional study. Methods: The Clarivate Analytics Web of Knowledge database was utilized to gather metrics on the 50 most cited articles on patellar tendon injury on June 27, 2022. The information extracted from each article included publication year, number of citations, author information, article type, level of evidence, country of origin, journal name, study focus, and industry influence. Results: The top 50 studies were cited a total of 8543 times and published between 1977 and 2015. The majority of articles were published after 2003, and the majority of citations were accrued after 2011. The most prevalent article types were cohort studies (n = 23), and the majority of studies were of evidence level 2 (n = 14) or 4 (n = 13). Australia and the United States (US) each published the most studies (n = 11). Only 4 (8%) studies focused on patellar tendon rupture, and 12 (24%) of the top 50 studies were associated with industry. Conclusion: The majority of the top 50 most influential articles in patellar tendon injury were published and accumulated citations in the past 10 to 20 years. Non-US countries, institutions, and journals published many of the top 50 studies, reflecting a global interest and commitment to research in this field. Patellar tendon rupture and surgical repair represents a minority of research in the top 50 studies and could be a point of growth in the future.

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.

Purpose To determine the most frequently cited articles relating to ice hockey since 2000 and conduct a bibliometric analysis of these publications. Methods The Clarivate Web of Knowledge database was used to gather data and generate a list of publications relating to “ice hockey” on June 20, 2022. Articles were filtered by the total number of citations accrued and were included or excluded on the basis of relevance to ice hockey; no date of publication, language, or journal restrictions. After the 50 most highly cited articles were identified, articles published before the year 2000 were excluded to avoid bias. The information analyzed from each article included author name (first and last), publication year, country of origin, institutional affiliation (of the first and last author), journal name, research design, main research topic, competition level, and the level of evidence. Results Ultimately, 46 studies were included in this analysis. The total number of citations was 8,267 times with an average of 179.7 citations per article. The most cited article was cited 926 times. The articles came from 5 different countries, with the United States and Canada comprising 27 and 13 articles, respectively. All articles were published in English. The American Journal of Sports Medicine published the greatest number of articles. The most studied topic was concussion/traumatic brain injury (n = 26). Professional hockey was the most studied level of competition (n = 15), while college followed (n = 13). Three institutions, University of Calgary, Dartmouth School of Medicine, and University of North Carolina at Chapel Hill were responsible for 32.6% of the top articles (n = 15). Conclusions The majority of the most cited articles relating to ice hockey are cohort studies, review articles, and epidemiological studies originating from the United States or Canada. The majority of publications included in the analysis focused on concussion and traumatic brain injury prevalence, identification, diagnosis, outcomes, and prevention, as well as the most studied level of competition was professional, but the greatest number of participants arose from the youth and high school level.

Background: Medicare reimbursement is rapidly declining in many specialties. An in-depth analysis of Medicare reimbursement for routinely performed diagnostic imaging procedures in the United States is warranted. Purpose/Hypothesis: The purpose of this study was to evaluate Medicare reimbursement trends for the 20 most common lower extremity imaging procedures performed between 2005 and 2020, including radiographs, computed tomography (CT), and magnetic resonance imaging (MRI). We hypothesized that Medicare reimbursement for imaging procedures would decline substantially over the studied period. Study Design: Cohort study. Methods: The Physician Fee Schedule Look-up Tool from the Centers for Medicare and Medicaid Services was analyzed for reimbursement rates and relative value units associated with the top 20 most utilized Current Procedural Terminology (CPT) codes in lower extremity imaging from 2005 to 2020. Reimbursement rates were adjusted for inflation and listed in 2020 US dollars using the US Consumer Price Index. To compare year-to-year changes, the percentage change per year and compound annual growth rate were calculated. A 2-tailed t test was used to compare the unadjusted and adjusted percentage change over the 15-year period. Results: After adjusting for inflation, mean reimbursement for all procedures decreased by 32.41% ( P = .013). The mean adjusted percentage change per year was –2.82%, and the mean compound annual growth rate was –1.03%. Compensation for the professional and technical components for all CPT codes decreased by 33.02% and 85.78%, respectively. Mean compensation for the professional component decreased by 36.46% for radiography, 37.02% for CT, and 24.73% for MRI. Mean compensation for the technical component decreased by 7.76% for radiography, 127.66% for CT, and 207.88% for MRI. Mean total relative value units decreased by 38.7%. The commonly billed imaging procedure CPT 73720 (MRI lower extremity, other than joint, with and without contrast) had the greatest adjusted decrease of 69.89%. Conclusion: Medicare reimbursement for the most billed lower extremity imaging studies decreased by 32.41% between 2005 and 2020. The greatest decreases were noted in the technical component. Of the modalities, MRI had the largest decrease, followed by CT and then radiography.

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. Purpose: To identify the 50 most cited research publications related to American football. Study Design: Cross-sectional study. Methods: The Clarivate Analytics Web of Science database was used to generate a list of publications relating to football. Articles were filtered by the total number of citations, and the top 50 most cited articles studying the sport of football were selected for this analysis. Articles were analyzed by author, publication year, country of origin, institution affiliation, journal, article type, main research topic area, competitive level, and the level of evidence. A total of 247 articles were reviewed to reach the top 50 articles. Results: The most studied topic within the top 50 articles was concussion/chronic traumatic encephalopathy (n = 40). Collegiate football was the most studied level of competition (n = 25). The journal publishing the greatest number of top articles was Neurosurgery. Two institutions, the University of North Carolina at Chapel Hill and Boston University School of Medicine, produced over one-third of top 50 articles (n = 18). Conclusion: Our analysis indicated that most of the top 50 publications related to the sport of football focused on concussion and CTE, were observational, and were published during or after 2000. The most studied level of competition was collegiate football.

Background. Physician review websites (PRWs) are increasing in usage and popularity. Our purpose is to characterize one-star reviews of orthopedic oncology surgeons to understand factors in healthcare that contribute to patient satisfaction. Methods. Orthopedic oncology surgeons were randomly selected from the Musculoskeletal Tumor Society. A search for one-star reviews was performed on Google Reviews, Healthgrades, and Vitals.com. Reviews were classified as clinical or nonclinical. Statistical analyses were performed regarding the frequency of reviews and complaints for each category. Results. Of the 7,733 reviews discovered, 908 (11.7%) were identified as one-star reviews. Of 907 usable complaints, 362 (40.8%) were clinical and 545 (59.2%) were nonclinical. The most common nonclinical complaints included bedside manner (65%) and limited time with providers (19%). The most common clinical complaints included complications (26%) and disagreements with the treatment plan (26%). There were 120 surgical and 221 nonsurgical reviews. Surgical patients had a higher rate of clinical complaints. Nonsurgical patients had a higher rate of total complaints. Conclusion. To the best of our knowledge, this is the first study examining PRWs regarding orthopedic oncology surgeons. Most one-star reviews were due to nonclinical complaints from nonsurgical patients. The most common factors are bedside manner, limited time with provider, phone communication issues, and rude/unprofessional conduct.

Purpose To compare the 5‐year clinical and functional outcomes of the soft‐tissue quadriceps tendon (QT) with those of the hamstring tendon (HT) autograft. Methods A retrospective review of patients undergoing anterior cruciate ligament 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 2 groups were compared for differences in outcomes, including International Knee Documentation Committee (IKDC) score, Lysholm score, return to sport, and complications. Results 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 (9.64 mm vs 7.90 mm, P < .001). The IKDC and Lysholm scores were similar between the 2 groups at 2‐years’ postoperatively. At 5 years’ postoperatively, the QT group demonstrated significantly greater IKDC ( P = .018) and Lysholm ( P = .007) scores. The cohorts demonstrated similar rates of achieving minimal clinically important difference thresholds at both 2 and 5 years’ postoperatively. The 2 groups also demonstrated comparable rates of return to sport, time to return, and postoperative complications. Conclusions Although the QT autograft demonstrated increased patient‐reported outcome scores when compared with 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 noninferior results to the HT autograft at mid‐term follow‐up. Level of Evidence III, retrospective comparison study.

Purpose To investigate the characteristics of shoulder and elbow fellowship directors (FDs). Methods 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. Results 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; P = .04) and years as FD and Scopus H‐index (r = 0.42; P = .03). Conclusions 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. Clinical Relevance 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.
