ABSTRACT
OBJECTIVE: The goal was to evaluate institutional inequities in the US Military Health System in knee arthroplasty receipt within three years of knee osteoarthritis diagnosis when accounting for other treatments received (eg, physical therapy, medications). METHODS: In this retrospective observational cohort study, medical record data of patients (n = 29,734) who received a primary osteoarthritis diagnosis in the US Military Health System between January 2016 and January 2020 were analyzed. Data included receipt of physical therapy one year before diagnosis and up to three years after diagnosis, prediagnosis opioid and nonopioid prescription receipt, health-related factors associated with levels of racism, and the primary outcome, knee arthroplasty receipt within three years after diagnosis. RESULTS: In a generalized additive model with time-varying covariates, Asian and Pacific Islander (incidence rate ratio [IRR] 0.58, 95% confidence interval [CI] 0.45-0.74), Black (IRR 0.52, 95%CI 0.46-0.59), and Latine (IRR 0.66, 95%CI 0.52-0.85) patients experienced racialized inequities in knee arthroplasty receipt, relative to white patients (all P < 0.001). CONCLUSIONS: In the present sample, Asian and Pacific Islander, Black, and Latine patients were significantly less likely to receive a knee arthroplasty, relative to white patients. Taken together, system-level resources are needed to identify and address mechanisms underlying institutional inequities in knee arthroplasty receipt, such as factors related to systemic and structural, institutional, and personally mediated racism.

During a cesarean hysterectomy for placenta percreta, transesophageal echocardiography was used to monitor volume status and guide resuscitation. After delivery of the neonate but before massive surgical hemorrhage, a thrombus appeared in the inferior vena cava. Roughly 3 hours later, the patient had hemodynamic changes consistent with an intraoperative pulmonary embolism. Boluses of epinephrine stabilized the patient. An inferior vena cava filter was placed via an in situ internal jugular central venous cannula to prevent further embolic events. We believe transesophageal echocardiography is a useful monitor during surgery for placenta percreta.
