Periprosthetic joint infection (PJI) The most important measure against joint infections after total knee endoprostheses and total hip endoprostheses is the consistent compliance with the highest hygiene standards when implanting artificial hip or knee joints. In order to minimize the intraoperative transmission of germs, laminar airflow ceilings are used in many hospitals to minimize the presence of bacteria during surgery. In the vast majority of operating theaters, however, the existing laminar air flow ceilings are too small to cover both the preparation of instruments as well as the operating field. The laminar air flow ceilings do only protect the area below the ceiling but not outside where the instrument preparation takes place! Several studies demonstrated that the instruments prepared outside the laminar air flow zone are already contaminated before the surgery starts. Laminar air flow ceiling 3 Downflow The instruments are often prepared outside the laminar air flow ceiling and are already contaminated before the start of the operation! The longer the operation lasts, the higher the contamination of the instruments and thus the risk of infection Conventional operating theater Mixed ventilation with circular units In an conventional operating room there is no protection zone, neither for the instruments nor for the operating field. The instruments are already contaminated before the start of the operation! The longer the operation lasts, the higher the contamination of the instruments and thus the risk of infection.. Would you dare to open the knee arthroplasty or knee joint at the beginning of an operation? Of course not! Every surgeon knows that the artificial implant has to be opened at the very last minute to preserve the sterility but how long have the instruments being exposed in the operating room with whom the implant will be inserted?

Prevention of Periprosthetic joint infection (PJI) Periprosthetic joint infection (PJI) is a serious complication occurring in 1% to 2% of primary arthroplasties, which is associated with high morbidity and need for complex interdisciplinary treatment strategies. The challenge in the management of PJI is the persistence of micro-organisms on the implant surface in the form of biofilm. With a steadily increasing number of implantations, the number of PJI cases also rises continuously. Around two thirds of PJI cases are caused through intra-operative inoculation of micro-organisms.(Zimmerli...

Prevention of Periprosthetic joint infection (PJI) Many people in the general public think of ORs as ultra clean, even sterile, environments. For anyone working in ORs, it is clear that this view is far from the truth. Although modern ORs have strict measures to reduce contamination, the OR environment becomes contaminated with every person entering the operating room. The more people are present in an operating room the higher is the contamination with pathogens that cause infections including SSIs. Especially implant surgery need a very aseptic environment as already a few pathogens can...

Technical specifications The devices are extremely small and handy and can also be used in very small spaces. The removable instrument table by Operio is available in various lengths of 45 cm (for the smallest operations), 60 cm (for normal operations) and 75 cm (for operations that require a lot of instruments). The electrical height adjustment can be carried out by the sterile OR staff (using a sterile covered display) as well as by the other OR staff using a separate display. There is no need to purchase a separate instrument table for storing the instruments. The constant cleaning of...
