Access to robot-assisted total knee arthroplasty varies significantly by race/ethnicity.

Background: Racial/ethnic disparities in access to total knee arthroplasty (TKA) have been extensively demonstrated. Over the past several years, there has been a rapid increase in the utilization of robot-assisted TKA (RA-TKA). Therefore, this study sought to determine whether previously established racial/ethnic disparities extend to access to RA-TKA relative to conventional TKA.

Leaving the Patella Unresurfaced Does Not Increase the Risk of Short-Term Revision Following Total Knee Arthroplasty: An Analysis from the American Joint Replacement Registry.

The benefit of patellar resurfacing in total knee arthroplasty (TKA) remains uncertain, with conflicting evidence regarding associated revision rates and clinical outcomes. Although initial studies have reported higher revision rates associated with unresurfaced patellae, recent evidence questions the necessity of routine patellar resurfacing. This study aimed to evaluate the risk of revision following TKA performed with and without patellar resurfacing using data from the American Joint Replacement Registry (AJRR).

Comparison of estimated glomerular filtration rate using five equations to predict acute kidney injury following hip fracture surgery.

Background: Decreased estimated glomerular filtration rate (eGFR) is associated with acute kidney injury (AKI) following hip fracture surgery. Delaying surgery for preoperative treatment of comorbidities is controversial in this patient population. The purpose of this study was 1) to assess differences in demographics and comorbidities between AKI and non-AKI groups, 2) to analyze equations used in calculating eGFR, and 3) to identify the equation which best predicts the development of AKI following hip fracture surgery.

Routine Prescription of Proton Pump Inhibitors in the Perioperative Period is Associated With Decreased Rates of 2-Year Revision Surgery After Total Hip and Knee Arthroplasty.

Background: Proton pump inhibitors (PPIs) are often prescribed in conjunction with nonsteroidal anti-inflammatory drugs after total hip arthroplasty (THA) and total knee arthroplasty (TKA) due to their gastroprotective effects. In animal studies, it has been suggested that PPIs have immunosuppressive effects and impair fracture healing; however, the association between PPI use and adverse events following THA and TKA has not been well-studied.

Methods: An administrative claims database was queried for patients who underwent elective THA from 2010 to 2019.
