Background Citation analysis is commonly used to evaluate the impact of academic publications within an area of study. The purpose of this study is to review the publications with the highest Altmetric scores related to total hip arthroplasty (THA) and total knee arthroplasty (TKA) and assess the correlation with traditional bibliometrics. Methods Altmetric scores were obtained for the top articles relating to THA and TKA and organized from highest to lowest scores. The Clarivate Analytics Web of Knowledge database was used to search the top articles by Altmetric score. Articles meeting inclusion criteria were reviewed for various metrics, including number of citations, journal impact factor at the time of publication, and study type and design. Results The top THA and TKA publications were cited 3042 times and 7523 times, respectively. The former were published in journals with an average impact factor of 17.861, and the latter in journals with an average impact factor of 15.564. For THA, Altmetric score demonstrated a significant, weakly positive correlation with the number of citations ( P = .008). For TKA, Altmetric score was found to have a significant, weakly positive correlation with impact factor of journal ( P = .04); however, it was nonsignificant for citation count ( P = .11). When one outlier is removed, the correlation with citation count is statistically significant ( P = .009). Conclusion While alternative metrics cannot replace traditional bibliometrics, they may serve a complimentary role in describing the influence of research. Thus, the Altmetric score represents an additional tool to identify the most influential articles to guide learning and evidence-based practice.

Background: Osgood-Schlatter disease (OSD) and tibial tubercle fractures are pathologies that affect the tibial tubercle apophysis in preadolescents and adolescents. Anatomic alignment of the proximal tibia may explain why some children develop OSD or sustain tibial tubercle fractures and some do not. Recent data has shown an association between posterior tibial slope angle (PTSA) and both OSD and proximal tibia physeal fractures. In this study, we compare radiographic parameters between patients with non-OSD knee pain, knees with OSD, and knees with tibial tubercle fracture to elucidate a difference between these groups. Methods: Patients treated for OSD, tibial tubercle fractures, and knee pain, from 2012 to 2018, were retrospectively reviewed. Radiographic parameters for each study group included PTSA, anatomic lateral distal femoral angle, anatomic medial proximal tibial angle, patellar articular height, and the distance from the inferior aspect of the patellar articular surface. Caton-Deschamps index was then calculated. Demographic data was collected including age, sex, and body mass index. Demographic and radiographic data was compared using analysis of variance tests, χ 2 tests, 2-sample t tests, and multiple linear regression. Results: Two hundred fifty-one knees in 229 patients met inclusion criteria for the study. In all, 76% were male and the average age of the overall cohort was 14 years old. In patients with tibial tubercle fractures, the majority of fractures were Ogden type 3b (65%). After controlling for demographic variability, average PTSA in the fracture cohort was significantly greater than that in the control cohort (β = 3.49, P < 0.001). The OSD cohort had a significantly greater posterior slope (β = 3.14) than the control cohort (P < 0.001). There was no statistically significant difference between the fracture and OSD cohorts. There was also no difference in Caton-Deschamps index between the 2 study groups when compared with the control group. Conclusion:This study demonstrates that patients with tibial tubercle fractures and patients with OSD have an increased PTSA when compared with the control group. This information adds to the body of evidence that increased tibial slope places the proximal tibial physis under abnormal stress which may contribute to the development of pathologic conditions of proximal tibia such as OSD and tibial tubercle fractures.

Update This article was updated on January 13, 2023, because of a previous error. On page 3, in the section entitled “Atypical Anatomy,” the sentence that had read “An intraforaminal anomaly, also known as VA tortuosity, refers to medial migration of the VA to <15 mm lateral to the uncovertebral joint of the vertebral body18.” now reads “An intraforaminal anomaly, also known as VA tortuosity, refers to medial migration of the VA to <1.5 mm lateral to the uncovertebral joint of the vertebral body18.” An erratum has been published: JBJS Rev. 2023;11(1):e20.00118ER. » Although rare, injury to the vertebral artery (VA) can occur after blunt trauma or iatrogenically during surgery. Clinicians should be aware of the anatomic variants of the VA, the presence of which may increase the risk of iatrogenic VA injury (VAI).» If VAI is suspected following blunt trauma, rapid identification via advanced imaging modalities, such as computed tomography angiography, can help clarify the site of injury and guide management.» VAI can be classified according to the Denver grading scale for blunt cerebrovascular injury, ranging from grade I to grade V, which includes intimal narrowing, pseudoaneurysm formation, complete occlusion, and arterial transection.» Treatment modalities remain controversial and include anticoagulation, endovascular interventions, surgical tamponade, ligation, and microvascular repair. The choice of treatment is influenced by the setting of the injury (iatrogenic injury in the operating room versus blunt trauma in the field) and the laterality of the dominant VA with respect to brain perfusion.

Aims Corticosteroid injections are often used to manage glenohumeral arthritis in patients who may be candidates for future total shoulder arthroplasty (TSA) or reverse shoulder arthroplasty (rTSA). In the conservative management of these patients, corticosteroid injections are often provided for symptomatic relief. The purpose of this study was to determine if the timing of corticosteroid injections prior to TSA or rTSA is associated with changes in rates of revision and periprosthetic joint infection (PJI) following these procedures. Methods Data were collected from a national insurance database from January 2006 to December 2017. Patients who underwent shoulder corticosteroid injection within one year prior to ipsilateral TSA or rTSA were identified and stratified into the following cohorts: < three months, three to six months, six to nine months, and nine to 12 months from time of corticosteroid injection to TSA or rTSA. A control cohort with no corticosteroid injection within one year prior to TSA or rTSA was used for comparison. Univariate and multivariate analyses were conducted to determine the association between specific time intervals and outcomes. Results In total, 4,252 patients were included in this study. Among those, 1,632 patients (38.4%) received corticosteroid injection(s) within one year prior to TSA or rTSA and 2,620 patients (61.6%) did not. On multivariate analysis, patients who received corticosteroid injection < three months prior to TSA or rTSA were at significantly increased risk for revision (odds ratio (OR) 2.61 (95% confidence interval (CI) 1.77 to 3.28); p < 0.001) when compared with the control cohort. However, there was no significant increase in revision risk for all other timing interval cohorts. Notably, Charlson Comorbidity Index ≥ 3 was a significant independent risk factor for all-cause revision (OR 4.00 (95% CI 1.40 to 8.92); p = 0.036). Conclusion There is a time-dependent relationship between the preoperative timing of corticosteroid injection and the incidence of all-cause revision surgery following TSA or rTSA. This analysis suggests that an interval of at least three months should be maintained between corticosteroid injection and TSA or rTSA to minimize risks of subsequent revision surgery.
