Abstract：
BACKGROUND: Robot-assisted total joint arthroplasty (robotic-TJA) has become more widespread over the last 20 years due to higher patient satisfaction and reduced complications. However, robotic TJA may have longer operative times and increased operating room traffic, which are known risk factors for contamination events. Contamination of surgical instruments may be contact- or airborne-related with documented scalpel blade contamination rates up to 9%. The robot arm is a novel instrument that comes in and out of the surgical field, so our objective was to assess whether the robot arm is a source of contamination when used in robotic TJA compared to other surgical instruments.
METHODS: This was a prospective, single-institution, single-surgeon pilot study involving 103 robotic TJAs. The robot arm was swabbed prior to incision and after closure. Pre- and postoperative control swabs were also collected from the suction tip and scalpel blade. Swabs were incubated for 24 hours on tryptic soy agar followed by inspection for growth of any contaminating bacteria.
RESULTS: A contamination event was detected in 10 cases (10%). The scalpel blade was the most common site of contamination (8%) followed by the robot arm (2%) and suction tip (0%).
CONCLUSIONS: Robotic TJA is contaminated with bacteria at a rate around 10%. Although the robot arm is an additional source of potential contamination, the robot arm accrues bacterial contamination infrequently compared to the scalpel blade.
CONCLUSIONS: Contamination of the robot arm during robotic TJA is minimal when compared to contamination of the scalpel blade.

摘要：
背景：由于更高的患者满意度和减少的并发症，机器人辅助的全关节置换术（机器人-TJA）在过去20年中变得越来越普遍。然而,机器人TJA可能有更长的手术时间和增加的手术室流量，这是已知的污染事件的危险因素。手术器械的污染可能与接触或空气传播有关，记录在案的手术刀刀片污染率高达9％。机器人手臂是一种进出手术领域的新型仪器，因此,我们的目的是评估与其他手术器械相比,机器人臂在机器人TJA中使用时是否是污染源.
方法：这是一个前瞻性的，单一机构，单外科医生试点研究，涉及103个机器人TJA。在切口之前和闭合之后擦拭机器人臂。还从抽吸尖端和手术刀刀片收集术前和术后对照拭子。将拭子在胰蛋白酶大豆琼脂上孵育24小时,然后检查任何污染细菌的生长。
结果：发现10例（10%）污染事件。手术刀刀片是最常见的污染部位（8％），其次是机器人手臂（2％）和抽吸尖端（0％）。
结论：与手术刀刀片的污染相比，机器人手臂在机器人TJA期间的污染最小。
