Perioperative acute kidney injury (AKI) can be associated with lower limb arthroplasty and increases morbidity, length of stay, and mortality. AKI is more prevalent in some antibiotic regimes compared with others. The aim of the present study is to assess the impact of cefuroxime (CEF), with or without gentamicin (±G), on AKI rates. ⋯ C ± G yields low rates of infection and AKI compared with high-dose penicillin-based regimes. It is a safe and effective choice for lower limb arthroplasty.

Multiple-Dose Intravenous Tranexamic Acid Further Reduces Hidden Blood Loss After Total Hip Arthroplasty: A Randomized Controlled Trial.
The most appropriate dose of tranexamic acid in total hip arthroplasty (THA) has not been decided. This study was conducted to evaluate the clinical effects of multiple-dose intravenous tranexamic acid (IV-TXA) in THA. ⋯ The 5-dose IV-TXA regimen can further diminish HBL, decrease maximum Hb drop, provide additional fibrinolysis control, and ameliorate postoperative inflammatory response following THA.

The traditional goal of the gap-balancing method in total knee arthroplasty is to create equal and symmetric knee laxity throughout the arc of flexion. The purpose of this study was to (1) quantify the laxity in the native and the replaced knee throughout the range of flexion in gap-balancing total knee arthroplasty (TKA) and (2) quantify the precision in achieving a targeted gap profile throughout flexion using a robotic-assisted technique with active ligament tensioning. ⋯ Aiming for equal gaps at 0° and 90° of flexion produced equal gaps in extension and flexion with larger gaps in midflexion. Consistent soft-tissue balance to a planned gap profile could be achieved by using controlled ligament tensioning in robotic-assisted TKA.

One potential benefit of the direct anterior approach (DAA) for total hip arthroplasty is the ability to use intraoperative fluoroscopy for acetabular cup positioning and limb-length evaluation. Previous studies comparing the use of fluoroscopy with an anterior approach to a posterior approach have reported conflicting results. To our knowledge, no prior study has compared acetabular cup position and limb-length discrepancy (LLD) using a DAA with and without fluoroscopy. ⋯ This study found no clinically or statistically significant difference in acetabular inclination, anteversion, or LLD between the fluoroscopy and nonfluoroscopy groups. Both surgeons achieved a similar mean acetabular cup position and an equivalent mean LLD.

Bundled payments are meant to reduce costs and improve quality of care. Without adequate risk adjustment, bundling may be inequitable to providers and restrict access for certain patients. This study examines patient factors that could improve risk stratification for the Comprehensive Care for Joint Replacement (CJR) bundled-payment program. ⋯ Large database analysis; Level III.
