Revision and Conversion to Arthroplasty Are Low Among Adolescents Undergoing Meniscal Allograft Transplantation Using the Bridge-In-Slot Technique at Midterm Follow-Up.

PURPOSE: To report midterm outcomes after primary medial and lateral meniscal allograft transplantation (MAT) with fresh-frozen allografts implanted with the bridge-in-slot technique in the adolescent patient population. METHODS: Adolescent patients less than 18 years old at the time of primary MAT from 1999 to 2016 were retrospectively identified. International Knee Documentation Committee (IKDC) subjective form, Lysholm, and Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales scores were collected before surgery and at 1-year, 2-year, and a minimum 5-year follow-up. Thresholds for achieving clinically significant outcomes were calculated, and the proportion of patients achieving minimal clinically important difference (MCID), patient-acceptable symptomatic state (PASS), and substantial clinical benefit (SCB) was determined. Meniscus reoperation (partial, subtotal, or total meniscectomy, repair, or failure) and failure (revision MAT or conversion to arthroplasty) rates were determined. RESULTS: Forty-four (female n = 33; male n = 11) of 62 identified patients met inclusion criteria and were followed for a mean of 9.5 ± 3.8 years (range, 5.0-17.7). Lateral MAT was performed in most patients (n = 35/44 [80%]). Isolated MAT was performed in 27 (61%) patients. Common concomitant procedures included osteochondral allograft transplantation (32%), autologous chondrocyte implantation (18%), and anterior cruciate ligament reconstruction (14%). MCID, PASS, and SCB were achieved by patients at a minimum 5-year follow-up for IKDC (62%; 76%; 31%), Lysholm (62%; 79%; 23%), and KOOS questionnaires (Pain [65%; 81%; 41%], Symptoms [58%; 81%; 47%], Activities of Daily Living [53%; 77%; 35%], Sport [86%; 75%; 50%], and Quality of Life [59%; 81%; 59%]), respectively. Fourteen patients (32%) underwent reoperation at an average of 5.0 ± 4.3 years (range, 0.8-14.0) after MAT. Three (7%) patients met criteria for failure, requiring revision MAT an average of 3.8 ± 1.1 years (range, 2.8-4.9) after transplantation. No patients underwent arthroplasty. Overall survival free from failure at 1, 2, 5, and 10 years was 100%, 100%, 93%, and 93%, respectively. At the time of final follow-up, 80% of patients reported satisfaction with their current physical status. CONCLUSIONS: Primary MAT in adolescent patients resulted in significant and durable functional improvements at mid- to long-term follow-up. At an average of 9.5 years after surgery, meniscal reoperation rate was 32% whereas graft survival free of revision MAT was 93%. Adolescents undergoing MAT demonstrated similar functional outcomes and graft survivability when compared to available adult MAT literature. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Indications and Technique: Rotator Cuff Repair Augmentation.

Rotator cuff repair (RCR) augmentation is often considered for patients with large-to-massive rotator cuff tears or chronic tears with poor tissue quality. Augmentation can provide mechanical stability and improved biology to improve the likelihood of a successful repair. This article discusses the indications, diagnosis, surgical techniques, and outcomes for RCR augmentation using an acellular dermal allograft, partially demineralized cancellous allograft, dermal xenograft, bone marrow aspirate concentrate, and platelet-rich plasma.

Accuracy of a Smartphone Software Application Compared With a Handheld Goniometer for Measuring Shoulder Range of Motion in Asymptomatic Adults.

Background: Typically, shoulder range of motion (ROM) measurements are performed in a clinic setting, where physicians, physical therapists (PTs), and occupational therapists make use of a goniometer. Purpose: To determine the accuracy of a smartphone-based ROM software application (app) in assessing active shoulder ROM and compare the measurements with traditional goniometry as measured by a PT. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: This prospective, nonblinded study was conducted at a single institution with adult asymptomatic participants with full active ROM of both shoulders. Participants were enrolled between June 1 and 15, 2021. Each participant self-assessed their active shoulder ROM using the PeerWell smartphone app. A single PT concurrently measured each participant's active shoulder ROM using a handheld universal goniometer. Bilateral shoulder ROM (forward flexion, abduction [AB], external rotation, internal rotation [IR], and extension) was measured 2 times for each participant. Interrater reliability between the smartphone app and PT measurements as well as intrarater reliability for each method of measurement were assessed using the intraclass correlation coefficient (ICC), and limits of agreement were analyzed for the difference in measurement methods. Results: Data were analyzed for 60 shoulders (30 right, 30 left) from 30 participants (mean age, 31.4 ± 11.7 years; 73% female). The interrater reliability between the 2 methods was excellent for all movements (ICCs, 0.90-0.96). For all movements except shoulder AB, the mean difference in the measurements between the 2 methods was <1.3°; the mean difference in AB ROM was 2.08°. For all movements except IR, both PTs and the app showed excellent intrarater reliability (ICCs >0.90); for IR, good intrarater reliability (ICC ≥0.75) was observed. Conclusion: The PeerWell smartphone app provided measurements comparable with manual measurements taken by a PT using a goniometer. These data provide evidence that the smartphone app is a reliable and valid tool for measuring shoulder ROM and show promise for measuring and monitoring patient ROM remotely.

Long-term outcomes after osteochondral allograft transplantation to the humeral head.

BACKGROUND: Long-term outcomes of osteochondral allograft (OCA) transplantation to the humeral head have been sparsely reported in the literature. PURPOSE: To evaluate outcomes and survivorship of OCA transplantation to the humeral head in patients with osteochondral defects at a minimum of 10 years of follow-up. METHODS: A registry of patients who underwent humeral head OCA transplantation between 2004 and 2012 was reviewed. Patients completed pre and postoperative surveys including the American Shoulder and Elbow Surgeons score, Simple Shoulder Test, Short Form 12 (SF-12), and the visual analog scale. Failure was defined by conversion to shoulder arthroplasty. RESULTS: Fifteen of 21 (71%) patients with a minimum of ten year of follow-up (mean: 14.2 ± 2.40) were identified. Mean patient age was 26.1 ± 8.8 years at the time of transplantation and eight (53%) patients were male. Surgery was performed on the dominant shoulder in 11 of the 15 (73%) cases. The use of local anesthetic delivered via an intra-articular pain pump was the most often reported underlying etiology of chondral injury (n = 9; 60%). Eight (53%) patients were treated with an allograft plug, while seven (47%) patients were treated with a mushroom cap allograft. At final follow-up, mean American Shoulder and Elbow Surgeons (49.9 to 81.1; P = .048) and Simple Shoulder Test (43.1 to 83.3; P = .010) significantly improved compared to baseline. Changes in mean SF-12 physical (41.4 to 48.1; P = .354), SF-12 mental (57.5 to 51.8; P = .354), and visual analog scale (4.0 to 2.8; P = .618) did not reach statistical significance. Eight (53%) patients required conversion to shoulder arthroplasty at an average of 4.8 ± 4.7 years (range: 0.6-13.2). Kaplan-Meier graft survival probabilities were 60% at 10 years and 41% at 15 years. CONCLUSION: OCA transplantation to the humeral head can result in acceptable long-term function for patients with osteochondral defects. While patient-reported outcomes metrics were generally improved compared to baseline, OCA graft survival probabilities diminished with time. The findings from this study can be used to counsel future patients with significant glenohumeral cartilage injuries and set expectations about the potential for further surgery.

Patients With Femoroacetabular Impingement Obtain Information From Low-Quality Sources Online and Are Most Interested in Conservative Treatment and Expected Recovery.

Purpose: To investigate the type of questions patients undergoing hip arthroscopy for femoroacetabular impingement (FAI) are searching online and determine the type and quality of the online sources from the top results to each query by the "people also ask" Google algorithm. Methods: Three search strings pertaining to FAI were carried out through Google. The webpage information was manually collected from the "People also ask" Google algorithm. Questions were categorized using Rothwell's classification method. Each website was assessed using Journal of the American Medical Association Benchmark Criteria for source quality. Results: A total of 286 unique questions were collected with their associated webpages. The most common questions included: "How do you treat femoroacetabular impingement and labral tears without surgery?" "What is the recovery process after hip arthroscopy and are there limitations after surgery?" and "How do you diagnose hip impingement and differentiate from other causes of hip pain?" The Rothwell Classification of questions were fact (43.4%), policy (34.3%), and value (20.6%). The most common webpage categories were Medical Practice (30.4%), Academic (25.8%), and Commercial (20.6%). The most common subcategories were Indications/Management (29.7%) and Pain (13.6%). Government websites had the highest average Journal of the American Medical Association score (3.42), whereas Single Surgeon Practice websites had the lowest (1.35). Conclusions: Commonly asked questions on Google regarding FAI and labral tears pertain to the indications and management of pathology as well as pain control and restrictions in activity. The majority of information is provided by medical practice, academic, and commercial sources, which have highly variable academic transparency. Clinical Relevance: By better understanding which questions patients ask online, surgeons can personalize patient education and enhance patient satisfaction and treatment outcomes after hip arthroscopy.

Rotator cuff repair: what questions are patients asking online and where are they getting their answers?

BACKGROUND: This study analyzed questions searched by rotator cuff patients and determined types and quality of websites providing information. METHODS: Three strings related to rotator cuff repair were explored by Google Search. Result pages were collected under the "People also ask" function for frequent questions and associated webpages. Questions were categorized using Rothwell classification and topical subcategorization. Webpages were evaluated by Journal of the American Medical Association (JAMA) benchmark criteria for source quality. RESULTS: One hundred twenty "People also ask" questions were collected with associated webpages. Using the Rothwell classification of questions, queries were organized into fact (41.7%), value (31.7%), and policy (26.7%). The most common webpage categories were academic (28.3%) and medical practice (27.5%). The most common question subcategories were timeline of recovery (21.7%), indications/ management (21.7%), and pain (18.3%). Average JAMA score for all 120 webpages was 1.50. Journal articles had the highest average JAMA score (3.77), while commercial websites had the lowest JAMA score (0.91). The most commonly suggested question for rotator cuff repair/ surgery was, "Is rotator cuff surgery worth having?," while the most commonly suggested question for rotator cuff repair pain was, "What happens if a rotator cuff is not repaired?" CONCLUSIONS: The most commonly asked questions pertaining to rotator cuff repair evaluate management options and relate to timeline of recovery and pain management. Most information is provided by medical practice, academic, and medical information websites, which have highly variable reliability. By understanding questions their patients search online, surgeons can tailor preoperative education to patient concerns and improve postoperative outcomes.

Internet search analytics for shoulder arthroplasty: what questions are patients asking?

BACKGROUND: Common questions about shoulder arthroplasty (SA) searched online by patients and the quality of this content are unknown. The purpose of this study is to uncover questions SA patients search online and determine types and quality of webpages encountered. METHODS: The "People also ask" section of Google Search was queried to return 900 questions and associated webpages for general, anatomic, and reverse SA. Questions and webpages were categorized using the Rothwell classification of questions and assessed for quality using the Journal of the American Medical Association (JAMA) benchmark criteria. RESULTS: According to Rothwell classification, the composition of questions was fact (54.0%), value (24.7%), and policy (21.3%). The most common webpage categories were medical practice (24.6%), academic (23.2%), and medical information sites (14.4%). Journal articles represented 8.9% of results. The average JAMA score for all webpages was 1.69. Journals had the highest average JAMA score (3.91), while medical practice sites had the lowest (0.89). The most common question was, "How long does it take to recover from shoulder replacement?" CONCLUSIONS: The most common questions SA patients ask online involve specific postoperative activities and the timeline of recovery. Most information is from low-quality, non-peer-reviewed websites, highlighting the need for improvement in online resources. By understanding the questions patients are asking online, surgeons can tailor preoperative education to common patient concerns and improve postoperative outcomes.

Repair of a Horizontal Cleavage Tear of the Lateral Meniscus with Circumferential Compression Stitches and Marrow Venting Augmentation.

Horizontal cleavage tears (HCTs) are challenging meniscal tear patterns, as they split the meniscus into inferior and superior leaflets, while also involving the central, less vascular portions of the meniscus. Circumferential compression sutures using an all-inside self-retrieving suture passing device like the Novostitch Pro (Smith & Nephew, Andover, MA) have demonstrated the ability to create stable repair constructs with uniform compression across both leaflets in the setting of HCTs. Additionally, biological augmentation of meniscal repairs using a marrow venting procedure (MVP) has demonstrated superior clinical outcomes relative to isolated meniscal repairs. Thus, the purpose of this technical note is to outline our procedure for implementing circumferential compression sutures and biologic augmentation using an MVP for repairing an HCT of the lateral meniscus.

Humeral Head Resurfacing for Isolated Primary Humeral Osteoarthritis With a Large Chondral Defect.

Primary, isolated humeral head arthritis or focal chondral defects are uncommon and difficult to diagnose preoperatively. While these lesions have traditionally been treated with total shoulder arthroplasty, shoulder hemiarthroplasty is a viable option for patients with isolated humeral head disease and minimal degenerative changes in the glenoid. This approach can be performed in a minimally invasive fashion, which preserves bone stock and native biomechanics, and can be beneficial if conversion to total shoulder arthroplasty is required in the future and avoids risk of glenoid loosening or failure in younger and more active individuals. In this Technical Note and accompanying video, we describe our technique of humeral head resurfacing in a patient with isolated primary humeral osteoarthritis with a large focal chondral defect in the humeral head.

Meniscal Extrusion: A Critical Analysis Review.

➢: Pathologic meniscal extrusion can compromise meniscal function, leading to increased contact forces in the tibiofemoral compartment and the acceleration of osteoarthritic changes. ➢: Extrusion is typically defined as radial displacement of ≥3 mm outside the tibial border and is best diagnosed via magnetic resonance imaging, although ultrasonography has also demonstrated encouraging diagnostic utility. ➢: Surgical management of meniscal extrusion is based on the underlying etiology, the patient's symptom profile, the preexisting health of the articular surface, and the risk of future chondral injury and osteoarthritis.

Rotator Cuff Repair in the Pediatric Population Displays Favorable Outcomes: A Systematic Review.

Purpose: To systematically review the literature to determine the injury mechanisms, presentation, and timing of diagnosis for pediatric patients with intratendinous rotator cuff tears and to determine the efficacy of surgical intervention for affected patients. Methods: PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus were searched. Studies were included if they involved only pediatric patients, soft-tissue rotator cuff injuries managed surgically, and reported outcomes. Patient characteristics, injury mechanisms, physical examination and imaging findings, time to diagnosis, surgical technique, and treatment outcomes were extracted. Findings were descriptively analyzed with weighted means and proportions. Results: Twenty-one studies comprising 78 patients were included. The age range was 8 to 17 years and 57 were male. The supraspinatus (n = 56) was the most injured tendon. American football was the most reported sport played at the time of injury. Most patients were diagnosed within 6 months of injury via magnetic resonance imaging. Arthroscopic management was undertaken in 68 patients. Forty-six of 51 patients for whom data were available returned to sports at a range of 2.5 to 12 months postoperatively. Repair failure occurred in three patients. Conclusions: The extant literature regarding rotator cuff tears in pediatric patients is limited to reports of low methodological quality. Qualitative synthesis of this low-level literature reveals that rotator cuff tears are mostly reported in male collision sport athletes but may also occur in female athletes and/or throwing athletes. These injuries are often successfully managed via arthroscopic repair, and patients and their families can be reassured that the majority of patients return to sports following surgery. Level of Evidence: Level IV, systematic review of level IV studies.

Editorial Commentary: Intraoperative Platelet-Rich Plasma Injections for Open-Wedge High Tibial Osteotomies Effectively Improve Clinical Outcomes and Minimal Medial Joint Space Width: An Orthobiologic Application.

Osteoarthritis is a significant cause of morbidity and mortality involving the knee joint, and high tibial osteotomy is becoming more commonly used to treat severe knee osteoarthritis. In addition, the best management and therapies to mitigate osteoarthritis symptoms and progression may include biologic injections, as we focus on more than just structural abnormalities but also on the inflammatory environment in the joint. These therapies include platelet-rich plasma, bone marrow aspirate concentrate, cell-based therapies, adipose-derived stromal cells, and amniotic suspension allografts. Recent research supports a promising therapy: combined high tibial osteotomy and intraoperative, intraarticular platelet-rich plasma injection.

The impact of social media presence, age, and patient reported wait times on physician review websites for sports medicine surgeons.

BACKGROUND: When choosing physicians, patients often review options online via physician review websites, which may influence decisions on providers. PURPOSE: The purpose of this study is to investigate the impacts of social media usage, age, and patient reported wait times on online ratings for three popular review websites. STUDY DESIGN: Cross-sectional study. METHODS: The American Orthopaedic Society for Sports Medicine database was used to extract demographic information for all listed sports medicine surgeons in Florida. Overall ratings, number of ratings and comments, and patient reported wait-times were recorded from three leading review websites (Healthgrades.com, Vitals.com, Google.com). Professionally focused SM accounts were searched for each physician on Facebook.com, Twitter.com, Instagram, and LinkedIn.com. RESULTS: 102 orthopaedic sports medicine surgeons were included. At least one form of social media was used by 62.4% of our cohort. Those with social media had higher overall online physician ratings out of 5.00 across all review websites (Google:4.65vs4.44, p = 0.05; Healthgrades:4.41vs4.15, p = 0.03; Vitals:4.43vs4.14, p = 0.01). In bivariate analysis, older age was associated with lower ratings on Health Grades (Absolute difference (AD) -0.26, p < 0.0001), and social media was linked to higher ratings (Google: AD 0.21, p = 0.05; Healthgrades: AD 0.26, p = 0.03; Vitals: AD 0.29, p = 0.008). Longer wait times were associated with lower ratings in a dose-dependent manner in both bivariate and multivariable analysis. CONCLUSIONS: Social media use among sports medicine surgeons correlated with higher overall physician ratings. Potentially, younger surgeons increase social media use because of a heightened concern for online image, whereas older surgeons may have less value in using online platforms to capitalize on an online presence. Older age and increased patient reported wait times in office had a negative correlation with online reviews, which highlights that factors beyond the surgeon's skill sets can influence overall ratings.

Social media use by shoulder and elbow surgeons increases the number of ratings on physician review websites.

BACKGROUND: The use of physician review websites by patients is increasingly frequent. One potential way for shoulder and elbow surgeons to enhance their online reputation and attract patients is via social media, yet its impact is unknown. This study sought to analyze the effect of social media use on the number of online ratings and overall rating of shoulder and elbow surgeons. We secondarily studied variables affecting social media use. METHODS: The American Shoulder and Elbow Surgeons directory was probed to identify practicing surgeons. Surgeon evaluation data, including ratings, comments, and reviews, were compiled from 3 physician review websites (Google, Healthgrades, and Vitals). Google was queried to assess for a professional Facebook, Twitter, or Instagram account, as well as obtain information on surgeon training, practice location, and other demographic variables. RESULTS: A total of 646 surgeons met the inclusion criteria (93.8% male and 6.2% female surgeons). Overall, 37% had a professional social media account (Facebook, 23.1%; Twitter, 24.1%; and Instagram, 9.4%). Linear regression analysis showed that Facebook use correlated with an average increase of 48.6 in the number of ratings. No social media platform correlated with physician rating. The surgeons more likely to use social media were those who graduated residency in 2000 or later (40.8% vs. 29.2%), those who practiced in cities with higher populations (mean, 1188.9 vs. 708.4 [per 1000]), and those with more surgeons practicing in the same city (mean, 7.0 vs. 5.0). CONCLUSION: The majority of shoulder and elbow surgeons do not have a professional social media account. Those using this platform are younger and located in more populous cities with more competition. Having a professional social media profile was not correlated with ratings, but there was a positive association with the number of online ratings, and Facebook had the strongest association. Surgeon ratings are overwhelmingly positive with minimal variability; therefore, a high number of ratings confirms a surgeon's exceptional reputation. The residency graduation year, city population, and number of nearby surgeons affected ratings, although the absolute differences were minimal. For shoulder and elbow surgeons, a professional social media account correlates with an increase in the number of online physician ratings. Recent graduates practicing in competitive locations may feel increased pressure to leverage this in an attempt to build their practices.

The 50 Most-Cited Papers on Bankart Lesions.

PURPOSE: To analyze the 50 most-cited articles pertaining to "Bankart lesions," also known as anteroinferior labral tears, by means of citation analysis as well as to provide analysis and summary of the origins and trends of research on Bankart lesions. METHODS: Scopus was used to query the literature on Bankart lesions. Included articles were related to Bankart lesions and the indications, risk factors, techniques, and outcomes of arthroscopic and open Bankart repair. The 50 most-cited articles were analyzed in the following areas: year of publication, citations in the most recent year, total citation count, contributing authors, institutions, countries, and journals, article classifications, and level of evidence. RESULTS: Years of publication ranged from 1938 to 2013. There were 608 total citations in the most recent year. Total citation count was 12,441. Regarding country, journal, and authorship, United States, R. A. Arciero, and Arthroscopy were the highest respective contributors. Rush University had the greatest number of publications. The most common article classification was clinical outcomes. Of 49 clinical articles, the most frequent Level of Evidence was IV. The majority of the top 50 Bankart literature consisted of case series and retrospective studies performed in the United States. CONCLUSIONS: Our findings are consistent with the hypothesis that the 50 most-cited articles about Bankart lesions are predominantly U.S.-based, produced by academic orthopaedic groups, clinical outcomes articles, and of Level IV and V evidence. This list of articles should serve as a reference tool for any orthopaedist looking to review Bankart literature.

Trends in leadership at orthopaedic surgery sports medicine fellowships.

BACKGROUND: Fellowship directors (FDs) in sports medicine influence the future of trainees in the field of orthopaedics. Understanding the characteristics these leaders share must be brought into focus. For all current sports medicine FDs, our group analyzed their demographic background, institutional training, and academic experience. AIM: To serve as a framework for those aspiring to achieve this position in orthopaedics and also identify opportunities to improve the position. METHODS: Fellowship programs were identified using both the American Orthopaedic Society for Sports Medicine and the Arthroscopy Association of North America Sports Medicine Fellowship Directories. The demographic and educational background data for each FD was gathered via author review of current curriculum vitae (CVs). Any information that was unavailable on CV review was gathered from institutional biographies, Scopus Web of Science, and emailed questionnaires. To ensure the collection of as many data points as possible, fellowship program coordinators, orthopaedic department offices and FDs were directly contacted via phone if there was no response via email. Demographic information of interest included: Age, gender, ethnicity, residency/fellowship training, residency/fellowship graduation year, year hired by current institution, time since training completion until FD appointment, length in FD role, status as a team physician and H-index. RESULTS: Information was gathered for 82 FDs. Of these, 97.5% (n = 80) of the leadership were male; 84.15% (n = 69) were Caucasian, 7.32% (n = 6) were Asian-American, 2.44% (n = 2) were Hispanic and 2.44% (n = 2) were African American, and 3.66% (n = 3) were of another race or ethnicity. The mean age of current FDs was 56 years old (± 9.00 years), and the mean Scopus H-index was 23.49 (± 16.57). The mean calendar years for completion of residency and fellowship training were 1996 (± 15 years) and 1997 (± 9.51 years), respectively. The time since fellowship training completion until FD appointment was 9.77 years. 17.07% (n = 14) of FDs currently work at the same institution where they completed residency training; 21.95% (n = 18) of FDs work at the same institution where they completed fellowship training; and 6.10% (n = 5) work at the same institution where they completed both residency and fellowship training. Additionally, 69.5% (n = 57) are also team physicians at the professional and/or collegiate level. Of those that were found to currently serve as team physicians, 56.14% (n = 32) of them worked with professional sports teams, 29.82% (n = 17) with collegiate sports teams, and 14.04% (n = 8) with both professional and collegiate sports teams. Seven residency programs produced the greatest number of future FDs, included programs produced at least three future FDs. Seven fellowship programs produced the greatest number of future FDs, included programs produced at least four future FDs. Eight FDs (9.75%) completed two fellowships and three FDs (3.66%) finished three fellowships. Three FDs (3.66%) did not graduate from any fellowship training program. The Scopus H-indices for FDs are displayed as ranges that include 1 to 15 (31.71%, n = 26), 15 to 30 (34.15%, n = 28), 30 to 45 (20.73%, n = 17), 45 to 60 (6.10%, n = 5) and 60 to 80 (3.66%, n = 3). Specifically, the most impactful FD in research currently has a Scopus H-index value of 79. By comparison, the tenth most impactful FD in research had a Scopus H-index value of 43 (accessed December 1, 2019). CONCLUSION: This study provides an overview of current sports medicine FDs within the United States and functions as a guide to direct initiatives to achieve diversity equality.

The 50 Most Cited Articles in Meniscal Injury Research.

BACKGROUND: Meniscal injuries are among the most common orthopaedic injuries, with a significant volume of published literature. PURPOSE: To perform a comprehensive bibliometric analysis that appropriately evaluates the 50 most cited articles in meniscal research. STUDY DESIGN: Cross-sectional study. METHODS: We performed a keyword search of the ISI Web of Knowledge database and then pared the results down to the 50 most cited articles using specific inclusion and exclusion criteria. Data extracted included title, first author, citation count, year of publication, topic, journal, article type, country of origin, and level of evidence. Correlation coefficients were calculated between publication date and citation density and between publication date and raw citation count. RESULTS: The 50 most cited articles were published from 1975 to 2013. The mean number of citations was 258.24 (range, 163-926; median, 225). The majority of articles were published in The American Journal of Sports Medicine (19%), the Journal of Bone and Joint Surgery (12%), and Arthritis & Rheumatology (14%). Most articles focused on either the anatomy and biomechanics of meniscal injury or on prevention and physical rehabilitation (12 papers each). CONCLUSION: The most popular fields of meniscal research involved anatomy/biomechanics and prevention/rehabilitation, and both are areas that will likely increase the probability of an article's being highly cited in the future. This study provided a quality selection of the most cited articles on meniscal injury and may provide a foundation for both beginner and senior clinician readers for further discussion and research.

The Effect of Thursday Night Games on In-Game Injury Rates in the National Football League.

BACKGROUND: Although claims of increased injury rates with Thursday night National Football League (NFL) games exist, a paucity of data exist substantiating these claims. PURPOSE: To evaluate the effect of rest between games on in-game injury rates as it pertains to overall injury incidence, location, and player position. STUDY DESIGN: Descriptive epidemiologic study. METHODS: Data were obtained from official NFL game books for regular season games from all 32 teams for the 2013-2016 seasons. All in-game injuries recorded in official game books were included. Rest periods between games were classified as short (4 days), regular (6-8 days), or long (≥10 days). Overall observed injury rates per team-game were analyzed in relation to different rest periods using negative binomial regression. For results with significant overall findings, pairwise comparisons were tested using the Wald chi-square test. Exploratory secondary analyses were performed in a similar fashion to assess differences in injury rates for the different rest periods when stratified by anatomic location and player position. RESULTS: A total of 2846 injuries were identified throughout the 4 seasons. There was an overall significant difference in injuries per team-game between short, regular, and long rest (P = .01). With short rest, an observed mean of 1.26 injuries per game (95% CI, 1.06-1.49) was significantly different from the 1.53 observed injuries per game with regular rest (95% CI, 1.46-1.60; P = .03), but not compared with the 1.34 observed injuries per game with long rest (P = .56). For player position, only the tight end, linebacker, and fullback group demonstrated significant differences between the injury rates for different rest categories. Quarterback was the only position with more injuries during games played on Thursday compared with both regular and long rest. This specific analysis was underpowered and the difference was not significant (P = .08). No differences were found regarding injury rates in correlation with differences in rest periods with different injury locations. CONCLUSION: A short rest period between games is not associated with increased rates of observed injuries reported in NFL game books; rather, our data suggest there are significantly fewer injuries for Thursday night games compared with games played on regular rest. Future research correlating rest and quarterback injury rates is warranted.

Mycobacterium bolletii Osteomyelitis of the Metaphyseal Distal Radius Treated With Amikacin Antibiotic Beads.

Mycobacterium bollettii, a subset of the group M. abscessus, is a slow-growing, nontuberculous mycobacterium that was first characterized in the early 2000s. We report a case of M. bollettii infection in an otherwise healthy 49-year-old man who sustained an open fracture of the right distal radius. After his initial surgery, the patient presented 1 month later with wound drainage requiring hardware removal and was treated with intravenous antibiotics. However, there was a persistent infection. We treated his osteomyelitis with debridement and placement of amikacin antibiotic beads. We selected this particularly uncommon antibiotic cement specifically to address the nontuberculous mycobacterium. The purpose of this report is to alert treating providers to the possibility of nontuberculous mycobacterium infections when an inflammatory process persists and to provide guidelines for the use of amikacin solution to produce antibiotic beads.

Achilles tendon complex: The anatomy of its insertional footprint on the calcaneus and clinical implications.

The Achilles tendon is the largest, and most commonly torn tendon in the body. The Achilles is usually torn at a region of relative hypo-vascularity proximal to its insertion. However, partial thickness tears and other pathologies often occur at its insertion on the calcaneus. Anatomically, the insertion is a confluence of the gastrocnemius and soleus muscles that fuse to form a myotendinous unit on the posterosuperior aspect of the calcaneus. This review aims to reveal the insertional footprint as individual fascicular components attaching to facets of calcaneal tuberosity. Understanding this anatomy is essential for interpreting tear patterns and surgical implications.
