My fondest orthopedic memory as a naive third year medical student was walking by the operating suite and seeing the resident and the attending on a total knee replacement suit up in full body suits with ventilation. "Oh," I thought in wonderment, "what commitment to a sterile environment!" Then a couple months later I was the student on service suiting up and I understood the truth: they're aerosolizing bone dust with those shrieking saws when they're implanting the new joint. The room was actually foggy with the stuff. The suits were to protect us! It's a gritty specialty.
