RESUMEN
CASE: Nail-patella syndrome (NPS) is a genetic disorder causing anatomical abnormalities about the knee, including significant patellar hypoplasia. We present a case of a patient with NPS and severe knee osteoarthritis undergoing computer-assisted total knee arthroplasty (TKA). Several intraoperative anatomical challenges were appreciated. Postoperatively, the patient developed arthrofibrosis requiring manipulation; however, his final outcome was favorable. CONCLUSION: Computer assistance may improve precision in patients with NPS undergoing TKA, but surgeons must be aware of the associated anatomic abnormalities and potentially increased risk of arthrofibrosis. Patellar resurfacing is often not feasible because of lack of bone stock.

OBJECTIVES: To report the results of retrograde intramedullary nailing (RIMN) for the treatment of extremely proximal femur fractures. DESIGN: Retrospective cohort study. SETTING: Level I trauma center. PATIENTS/PARTICIPANTS: 63 patients with femoral shaft fractures involving the anatomic region within 10 centimeters of the inferior border of the lesser trochanter, which were treated with retrograde intramedullary nailing. INTERVENTION: Retrograde intramedullary femoral nail. MAIN OUTCOME MEASUREMENTS: Time to union, nonunion, malunion, and unplanned reoperation. RESULTS: Between 2009 and 2020, 63 fractures were followed up to fracture union, reoperation, or a minimum of 1 year clinically. The mean follow-up was 32 months, and 48 (76%) of the patients were followed up beyond 1 year clinically. The mean patient age was 34 years (range 18-84 years), and the mean BMI was 27 (range 14-45) kg/m 2 . Forty (64%) patients were polytraumatized. Clinical and radiographic union was achieved in 59 (94%) fractures after index operation at a mean time to union of 22 weeks (range 9-51 weeks). Delayed union requiring nail dynamization occurred in 1 (2%) instance. Malreduction was noted in 1 (2%) patient with a 12-degree flexion deformity that resulted in nonunion. In total, there were 3 (5%) nonunions requiring revision surgery, 1 treated with retrograde exchange nailing and 2 revised to cephalomedullary nails; all were united after revision. CONCLUSIONS: Retrograde intramedullary nailing can be an effective treatment strategy for extremely proximal femur fractures when necessary. Our series demonstrated a high rate of union and a low rate of malalignment and complications. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

PURPOSE: To identify the 50 most frequently cited publications related to hip arthroscopy. METHODS: The Clarivate Analytics Web of Knowledge database was used to search for publications relating to hip arthroscopy. The top 50 most cited articles that met the inclusion criteria were recorded and reviewed for various metrics. RESULTS: The top 50 publications were cited a total of 8,306 times, with an average of 437.2 total citations per year. Of the 50 articles identified, 44 had been published since 2000. Case series, expert opinion articles, and review articles were the most common study types. CONCLUSIONS: The majority of the most influential articles on hip arthroscopy are case series and expert opinions; however, as hip arthroscopy continues to become more widely performed, higher-level articles should supplant some of the articles included in this analysis. As indications for hip arthroscopy have expanded, so has its body of literature, with the vast majority of articles identified in our study having been published since 2000. Elucidating the 50 most cited articles in hip arthroscopy will allow practicing physicians a quick reference to the highest-yield articles and will allow residency programs to guide their education on the topic. CLINICAL RELEVANCE: The top 50 list provides residents, fellows, and researchers with a comprehensive list of the major academic contributions to hip arthroscopy.

Introduction and objectives: Acute abdominal pain (AAP) is one of the most common complaints in the emergency department (ED). Rapid diagnosis is essential and is often achieved through imaging. Computed tomography (CT) is widely considered an exemplary test in the diagnosis of AAP in adult patients. As previous studies show disparities in healthcare treatment based on insurance status, our objective was to assess the association between insurance status and frequency of CT ordered for adult patients presenting to the ED with AAP from 2005 to 2014. Methods: This study used the National Hospital and Ambulatory Medical Care Survey: Emergency Department Record (NHAMCS) database, which collects data over a randomly assigned 4 week period in the 50 states and DC, to perform an observational retrospective analysis of patients presenting to the ED with AAP. Patients with Medicaid, Medicare or no insurance were compared to patients with private insurance. The association between insurance status and frequency of CT ordered was measured by obtaining odds ratios along with 95% CIs adjusted for age, gender and race/ethnicity. Results: Individuals receiving Medicaid are 20% less likely to receive CT than those with private insurance (OR 0.8, CI 0.6-0.99, p = .046). Those on Medicare or who are uninsured have no difference in odds of obtaining a CT scan compared to patients with private insurance. Additional findings are that black patients are 42% less likely to receive a CT scan than white patients. Conclusions and implications: Patients on Medicaid are significantly less likely to receive a CT when presenting to the ED with AAP. Differences in diagnostic care may correlate to inferior health outcomes in patients without private insurance.
