A simple program is cutting surgical site infections by a dramatic percentage, according to orthopaedic traumatologist and joint reconstruction doctor Brian Tonne, M.D., at the University of Tennessee Medical Center. Before undergoing a hip or knee replacement patients take an infection-prevention class called “project joints.”
Extra Washing Cuts Surgical Site Infections

Patients’ noses are swabbed to check for the presence of staph bacteria and three days before their surgery doctors instruct prospective patients to wash with a special anti-bacterial, anti-septic soap. They tell them to spend three minutes scrubbing their affected limb. As an added precaution, doctors use clippers at the surgical site instead of razors.
The University of Tennessee Medical Center’s infection rate for knee and hip replacements was almost 2% before project joints. Now, “it has dropped to approximately 0.5%, ” Tonne said.
The “project joints” procedure is currently in use in hospitals in eight states and is expanding to facilities in five more, according to Tonne.
He indicated that the program is only being used for patients getting hip and knee replacements, but he believes it should be used in conjunction with other joint replacements and orthopedic procedures. He notes that every year 300, 000 Americans get surgical site infections—the most common healthcare associated infection in the U.S.

Discussion
This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
