Operating room disinfection: operator-driven ultraviolet 'C' vs. chemical treatment.

Background: In operating room (OR) surfaces, Nosocomial pathogens can persist on inanimate surfaces for long intervals and are highly resistant to traditional surface cleaning.

Aim: This study compares traditional chemical operating room terminal disinfection to a unique operator-driven device that emits germicidal UV light at short distance onto vertical and horizontal surfaces.

Methods: A randomized crossover analogous protocol assigned 40 end-of-day operating rooms into either group A (chemical then UVC treatments) or group B (UVC then chemical treatments).

A Short-Term Multicenter Analysis of Radiolucent Lines in a Single Uncemented Rotating Platform Implant for Total Knee Arthroplasty.

Background: Uncemented total knee arthroplasty is increasing as a potential solution for aseptic loosening via biologic fixation and to increase operative efficiency. However, postoperative radiolucent lines (RLLs) remain a concern for some clinicians. We report on a multicenter analysis of these RLLs over a 2-year period to identify their incidence, progression, and clinical significance.

Third-Generation Medium Cross-Linked Polyethylene Demonstrates Very Low Wear in Total Hip Arthroplasty.

Background: Cross-linked polyethylene (XLPE) liners have shown lower wear rates than conventional polyethylene liners in total hip arthroplasty. The primary aim of our study was to report our most recent analysis of wear rates and clinical outcomes of a third-generation XLPE liner. Secondary aims were to investigate the rate of adverse events related to mechanical failure or oxidation of this liner.
