Peri-prosthetic joint infection is a serious and expensive complication of joint arthroplasty. Theatre discipline has infection prevention at its core with multiple studies correlating increased door opening with surgical site infection. The WHO, NICE and Philadelphia Consensus all advocate minimal theatre traffic. The Dutch Health Inspectorate consider >5 door openings per procedure excessive. This prospective observational study over five weeks observed theatre door traffic during hip and knee arthroplasty within the eight laminar flow theatres at our institution. Two students attached to the department collected data. Half way through the study notices reminding people not to enter during arthroplasty were placed on the theatre doors.Aim
Method
The majority of peri-prosthetic joint infection occurring within 1 year of surgery is due to introduction of microbes at the time of surgery. Lavage of total knee replacement leaves a pool of fluid on the surgical drapes. This fluid could be a direct source of wound contamination via suction catheter tip, gloves or instruments. Twenty patients undergoing total knee arthroplasty had a sample of drape fluid sent, after prosthesis implantation, for standard and enrichment culture. The surgery took place in a laminar low theatre with scrub teams in togasAim
