Multicentre RCT across 19 hospitals randomizing over 8000 total hip and knee replacements between conventional ventilation and ultraclean-air OR systems. Asks whether reducing airborne bacterial contamination reduces confirmed deep joint sepsis requiring reoperation. Some centers also tested whole-body exhaust-ventilated suits and evaluated antibiotic prophylaxis as an independent variable.
Before this paper, sepsis rates after joint replacement reached 10% at some centers, and debate persisted for over a century about whether OR air quality actually mattered clinically. This trial settled that question: both ultraclean air and antibiotic prophylaxis independently reduce deep joint infection, and each layer of protection adds to the last.
When you scrub in for a primary THA or TKA, the laminar flow overhead, the prophylactic cefazolin you ordered preoperatively, and the surgical attire your team wears are all traceable to the framework this paper established — each cuts infection risk, and together they multiply the benefit.
The outcome data carry a practical warning: septic failures result in prosthesis reimplantation less than half the time, compared to over 90% for aseptic failures. Getting infection prevention right the first time is not just about avoiding morbidity. It is about preserving reconstructive options.
