While the novel Coronavirus 2019 disease’s (COVID-19) impact on the practice of orthopaedics has been readily apparent, the effects of COVID-19 on the orthopaedic literature has not been studied. The objective of this paper is to analyze the COVID-19 pandemic’s impact on peer-reviewed articles published in the orthopaedic surgery literature. Using the Journal Citation Reports, twenty orthopaedic surgery journals with the highest impact factor in 2019 were selected and articles within those journals were sorted by mention of COVID-19. The Altmetric Attention Score (AAS) and citation count were collected and compared for COVID-19 versus non-COVID-19 related articles using the Mann-Whitney U test. Furthermore, within COVID-19 related articles, AAS and citation count were compared using Kruskal-Wallis test between sub specialty of orthopaedics, type of article, study type, and quarter of publication. The average AAS of COVID-19 articles was significantly higher than non-COVID articles (15 vs. 6, p=0.019). Within COVID-19 articles, those pertaining to spine and trauma had a significantly lower AAS than those pertaining to orthopaedics as a whole (20 & 6 vs 51, p Orthopaedic articles related to COVID-19 demonstrated a greater influence, dissemination, and impact than articles not related to COVID-19 as demonstrated by AAS and citations accrued.

Total hip arthroplasty (THA) has been referred to as the operation of the century given its success and predictable improvement in quality of life. With the increase in number of THAs performed every year, there is a concomitant rise in the incidence of revision and re-revision surgeries. Failure of THA and revision hip arthroplasty may occur due to a variety of reasons, often in older patients with multiple comorbidities. Revision procedures in this setting are associated with worse outcomes as they are often complicated by limited bone stock and poor soft tissue and bone quality, making reconstruction more challenging. The purpose of this review is to discuss modern techniques for limb salvage following failed THA in the setting of significant bone loss. These include proximal femur replacement, total femur replacement, hip resection arthroplasty, and hip disarticulation.

Compressive neuropathies of the forearm are common and involve structures innervated by the median, ulnar, and radial nerves. A thorough patient history, occupational history, and physical examination can aid diagnosis. Electromyography, X-ray, and Magnetic Resonance Imaging may prove useful in select syndromes. Generally, first line therapy of all compressive neuropathies consists of activity modification, rest, splinting, and non-steroidal anti-inflammatory drugs. Many patients experience improvement with conservative measures. For those lacking adequate response, steroid injections may improve symptoms. Surgical release is the last line therapy and has varied outcomes depending on the compression. Carpal Tunnel syndrome (CTS) is the most common, followed by ulnar tunnel syndrome. Open and endoscopic CTS release appear to have similar outcomes. Endoscopic release appears to incur decreased cost baring a low rate of complications, although this is debated in the literature. Additional syndromes of median nerve compression include pronator syndrome (PS), anterior interosseous syndrome, and ligament of Struthers syndrome. Ulnar nerve compressive neuropathies include cubital tunnel syndrome and Guyon’s canal. Radial nerve compressive neuropathies include radial tunnel syndrome and Wartenberg’s syndrome. The goal of this review is to provide all clinicians with guidance on diagnosis and treatment of commonly encountered compressive neuropathies of the forearm.

Background: The novel coronavirus disease (COVID-19) has had a significant impact on orthopedic surgery practice, but there has been little investigation of the effects of COVID-19 on the orthopedic surgery literature. Additionally, because orthopedic research plays a vital role in physician education, changes to the characteristics and content of published literature can have lasting impacts on future teaching and learning. This paper represents the first known analysis of the COVID-19 pandemic's impact on peer-reviewed articles published in orthopedic surgery journals. Methods: The 20 orthopedic journals with the highest impact factors in 2019, according to the Journal Citation Reports, were included in this study. Using PubMed and COVID-19 related keywords as well as manual screening, a final count of 199 articles were assessed for this study and subsequently sorted by country of origin, orthopedic subspecialty, article type, and general theme. Kruskal Wallis and Pearson's Chi-squared tests were used to analyze continuous and categorical variables, respectively. Results: Fourteen journals published articles relating to COVID-19, representing 26 countries with the United States (37%) and United Kingdom (13%) publishing the greatest proportion of all COVID-19 articles. Sixty percent of publications discussed COVID-19's impact on the overall field of orthopedic surgery, with the remainder focusing on specific subspecialties. Forty-seven percent of publications were original research articles while 46% were editorials or commentaries. The median time to publication for all COVID-19 related articles was 24.5 days, compared to the 129 days reported for orthopedic journals prior to the COVID-19 pandemic (p

Mucopolysaccharidosis encompasses multiple lysosomal storage disorders that are relevant to the orthopedic surgeon as they lead to disruption in bone and cartilage development. These patients may present with early-onset joint pain, including end-stage hip arthritis warranting total hip replacement. The altered hip anatomy in this disorder is of specific importance to the arthroplasty surgeon as it presents challenges when reconstructing the proximal femur and acetabulum and informs implant choice. We present a 17-year-old patient with end-stage bilateral hip arthritis who underwent staged bilateral total hip arthroplasty. We discuss technical considerations in surgical technique and the consequences of acetabular and femoral deformity on implant selection.

Back pain may both decrease patient satisfaction after TKA and confound outcome assessment in satisfied patients. Our primary objective was to determine whether preoperative back pain is associated with differences in postoperative patient-reported outcome measures (PROMs). We retrospectively reviewed 234 primary TKA patients who completed PROMs preoperatively and 12 weeks postoperatively, which included a back pain questionnaire, the Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS JR) and the Forgotten Joint Score-12 (FJS-12). Cohorts were defined based on the severity of preoperative back pain (none, mild, moderate and severe) and compared. Demographics were compared using ANOVA and Chi-square analysis. Univariate ANCOVA analysis was utilized to compare PROMs while accounting for significant demographic differences. Both preoperative KOOS JR scores (none: 47.90, mild: 47.61, moderate: 44.61 and severe: 38.70; p = 0.013) and 12-week postoperative KOOS JR scores (none: 61.24, mild: 64.94, moderate: 57.48 and severe: 57.01; p = 0.012) had a statistically significant inverse relationship with regard to the intensity of preoperative back pain. Although FJS-12 scores at the 12-week postoperative period trended lower with increasing levels of preoperative back pain (p = 0.362), it did not reach statistical significance. Patients who reported severe back pain preoperatively achieved the largest delta improvement from baseline compared to those with lesser pain intensity (p = 0.003). Patients who had a 2-grade improvement in their back pain achieved significantly higher KOOS JR scores 12 weeks postoperatively compared to patients with either 1-grade or no improvement (63.53 vs. 55.98; p = 0.042). Both preoperative (47.99 vs. 41.11; p = 0.003) and 12-week postoperative (64.06 vs. 55.73; p

Objectives Residents receiving industry payments are not legally required to be reported on the Centers for Medicare & Medicaid Services (CMS) Open Payments Database. The purpose of this study is to review reporting of orthopedic surgery residents and identify the trends for which payments or transfers in value were received. Design The CMS Open Payments Database was used to search for all available orthopedic residents from 2014 to 2016. All data available on the CMS Open Payments Database was recorded. Setting/Participants This is a database study. Participants are residents reported in the CMS Open Payments Database. Results Over the 3-year period, 6832 resident “entities” were identified from 151 programs. A total of 3217 entities (47%) were reported as receiving payments from industry during this time period. This totaled $3,786,754 over the 3 year study period. The largest itemized categories for payment were education (32.5%) and grants (30.9%) totaling more than $2.4 million. Other areas of payment included travel (17.0%), food (16.0%), consultation fee (1.7%), research (0.8%), speaker fee (0.7%), gift (0.1%), honoraria (0.1%), and other (0.02%). Conclusion Overall, 47% of orthopedic resident entities were reported on the CMS Open Payments Database. The vast majority of payments were related to education and grants. Residents should become familiar with how to navigate the Open Payments Database and be educated on maintaining appropriate relationships with industry.

Background Isolated greater tuberosity fractures account for up to a fifth of all proximal humeral fractures. There have been several retrospective cohort studies and case series reporting outcomes after treatment of this pathology. This study aims to report on the clinical outcomes of surgically treated isolated greater tuberosity fractures, as well as diagnostic workup and complications associated with fracture fixation. Methods A systematic review was performed under PRISMA guidelines to identify studies that reported the results or clinical outcomes of isolated greater tuberosity fracture. The searches were performed using MEDLINE through PubMed, the Elsevier Embase database, and the Cochrane Database of Systematic Reviews. Results Sixteen studies met inclusion criteria comprising 345 patients and 345 shoulders. The mean age was 52.9 years and mean follow-up was 3.4 months. The mean postoperative American Shoulder and Elbow Surgeon Score, the most frequently utilized patient reported outcome measure across studies, was 90.1% of ideal maximum. All studies used standard shoulder radiographs in their initial workup and most commonly referred to a minimum of 5 mm displacement as an indication for surgery. Fifty five percent of patients were treated using open fixation and 35.9 with arthroscopic fixation. Ninety three percent of patients were able to return to work. A total of fifty-two (15.1%) complications were reported in the included studies. Conclusions The current literature describes overall satisfactory functional outcomes and minimal occupational morbidity following either open or arthroscopic fixation of isolated greater tuberosity fractures despite a notable rate of complications. Level of Evidence IV, systematic review.

BACKGROUND The Sunshine Act aims to increase the transparency of physicians receiving compensation from pharmaceutical and medical device companies. Nine states have supplementary legislation in addition to the Federal Sunshine Act. The purpose of this study is to assess the characteristics of financial compensation to orthopaedic residents on the Centers for Medicare and Medicaid Services (CMS) Open Payments Database in states with more restrictive regulations compared with those without additional restrictions. METHODS A complete list of accredited orthopaedic residency programs in the United States was compiled using the Accreditation Council for Graduate Medical Education and American Osteopathic Academy of Orthopedics websites. The website of each orthopaedic residency program was searched to compile a list of residents who attended their program from 2014 to 2016. The CMS Open Payments Database was used to search the residents identified for the corresponding years. All data available on the CMS Open Payments Database were recorded. RESULTS Over the 3-year period, 3,622 residents were identified from 151 programs. A total of 41% of the residents were reported as receiving compensation from the industry. The percent of residents reported from programs in less restrictive states was 45% versus 28% in more restrictive states (P < 0.001). Residents had a mean of 5.3 transactions per year in less restrictive states and 2.4 transactions per year in more restrictive states (P < 0.001). The mean compensation per resident reported was $2,730 for less restrictive sates versus $1,937 for more restrictive states (P < 0.001). DISCUSSION Overall, 41% of orthopaedic residents were reported on the CMS Open Payments Database with fewer transactions and less compensation going to residents in states with more restrictive legislature. Potential implications on resident education remain unknown.

Although tourniquet use in primary total knee arthroplasty (TKA) has been widely studied, the outcomes associated with tourniquet use in revision TKA (rTKA) remains relatively unexplored. This study investigates surgical outcomes and patient satisfaction in association with tourniquet use during aseptic rTKA.We retrospectively reviewed all patients who underwent rTKA for aseptic causes at our institution from 2011 to 2020. Patients were separated into 2 cohorts based on tourniquet inflation during the procedure. Outcomes of interest included estimated blood loss, change in hemoglobin, surgical time, length of stay, reoperation rate, and Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR) scores.Of the 1212 patients included, 1007 (83%) underwent aseptic rTKA with the use of a tourniquet and 205 (17%) without the use of a tourniquet. The mean tourniquet inflation time was 93.0 minutes (standard deviation 33.3 minutes). Blood loss was significantly less for patients in the tourniquet cohort as measured through estimated blood loss (224.1 vs 325.1 mL, P.001) and change in preoperative to postoperative hemoglobin (1.75 vs 2.04 g/dL, P.001). There were no statistical differences in surgical time (P = .267) and length of stay (P = .206) between the 2 groups. The reoperation rate was significantly greater for patients who did not have a tourniquet utilized (20.5% vs 15.0%, P = .038). Delta improvement in KOOS, JR scores from baseline to 3 months postoperatively did not statistically differ between the 2 cohorts (P = .560).Although delta improvements in KOOS, JR scores were similar for both cohorts, patients who did not have a tourniquet inflated during aseptic rTKA had increased blood loss and were more likely to undergo subsequent reoperation compared to patients who did.Retrospective Cohort Study.

The direct anterior approach (DAA) to the hip was initially described in the nineteenth century and has been used sporadically for total hip arthroplasty (THA). However, recent increased interest in tissue-sparing and small incision arthroplasty has given rise to a sharp increase in the utilization of the DAA. Although some previous studies claimed that this approach results in less muscle damage and pain as well as rapid recovery, a paucity in the literature exists to conclusively support these claims. While the DAA may be comparable to other THA approaches, no evidence to date shows improved long-term outcomes for patients compared to other surgical approaches for THA. However, the advent of new surgical instruments and tables designed specifically for use with the DAA has made the approach more feasible for surgeons. In addition, the capacity to utilize fluoroscopy intraoperatively for component positioning is a valuable asset to the approach and can be of particular benefit for surgeons during their learning curve. An understanding of its limitations and challenges is vital for the safe employment of this technique. This review summarizes the pearls and pitfalls of the DAA for THA in order to improve the understanding of this surgical technique for hip replacement surgeons.

Leiomyomas are benign tumors of smooth muscle origin. They are most commonly found in the uterus, but cutaneous leiomyomas may be occasionally present in the extremities and cause pain secondary to mass effect. Few studies have reported leiomyoma of the foot, and leiomyoma of the heel is particularly rare. We present a case of a 41-year-old female who presented to our clinic for a tender nodule on the posterior aspect of her right heel. The tumor was surgically excised and biopsied revealing cutaneous leiomyoma.

Total hip arthroplasty (THA) alleviates hip pain and improves joint function. Current implant design permits long-term survivorship of THAs, but certain metal-on-metal (MoM) articulations can portend catastrophic failure due to adverse local tissue reactions (ALTR). Here, we identified biological and molecular differences between periacetabular synovial tissues of patients with MoM THA failure undergoing revision THA compared to patients undergoing primary THA for routine osteoarthritis (OA). Analysis of tissue biopsies by RNA-sequencing (RNA-seq) revealed that MoM patient samples exhibit significantly increased expression of immune response genes but decreased expression of genes related to extracellular matrix (ECM) remodeling. Thus, interplay between local tissue inflammation and ECM degradation may account for the pathology and compromised clinical outcomes in select patients with MoM implants. We conclude that adverse responses of host tissues to implant materials result in transcriptomic modifications in patients with MoM implants that permit consideration of strategies that could mitigate ECM damage.

Background: Medial sesamoidectomy has been reported to be a safe and effective means of treating a range of pathologies including chronic sesamoiditis and fracture nonunion. The purpose of this case series is to determine common clinical indications for medial sesamoidectomy and to evaluate the postoperative clinical course and outcomes. Methods: A retrospective chart review was conducted on patients who had isolated medial sesamoidectomy from 2009 to 2018. Demographics, comorbidities, physical exam variables, operative findings, radiographic measurements including hallux valgus angle (HVA) and intermetatarsal angle (IMA), and clinical outcomes including visual analog score (VAS), Foot Function Index (FFI), and complications were gathered. Results: Twenty-six patients (13 males and 13 females) were identified to have undergone tibial sesamoidectomy with a mean age of 49.8±18.5 years. VAS improved significantly (5.27±2.41 to 0.91±1.14, P Conclusions: Isolated tibial sesamoidectomy, when utilized judiciously and with the right indications can improve pain and ulcer healing.
