Abstract：
UNASSIGNED: As the volume of technology-assisted total hip arthroplasty (THA) increases, there is a need to characterise the outcomes of robotic-assisted (RA) and computer-navigated (CN) THA. The goal of this study was to assess outcomes and opioid consumption following CN-THA and RA-THA compared to conventionally-instrumented (CON) THA.
UNASSIGNED: The Premier Database was queried for all patients who underwent primary, elective THA from 2015-2020. Patients were divided into 3 groups: CN, RA, or CON-THA. Yearly usage trends were assessed. Univariate and multivariate analyses were performed to assess the 90-day risk of postoperative complications. Opioid consumption was reported in morphine milligram equivalents (MME) for postoperative days (POD) 0 and 1.
UNASSIGNED: Overall, 474,707 elective THAs were identified (95.7% CON, 2.1% CN, 2.2% RA. After accounting for confounders, CN-THA patients were at decreased risk for periprosthetic joint infection (PJI) (aOR: 0.55, p < 0.001) and dislocation (aOR 0.45, p < 0.001), but increased risk for blood transfusion (aOR 1.97, <0.001) compared to CON-THA. RA-THA patients were at decreased risk of dislocation (aOR:0.66, p < 0.001) but increased risk for transfusion (aOR 1.20, p < 0.001), prosthesis breakage (aOR 3.88, p < 0.001), and periprosthetic fracture (aOR 1.72, p < 0.001). Opioid consumption for CN-THA patients was lower on POD1 and lower for RA-THA patients POD0 and 2 compared to CON-THA.
UNASSIGNED: CN-THA was associated with reduced rates of PJI and dislocation, but increased rates of blood transfusion while RA-THA was associated with decreased rates of dislocation, but increased rates of blood transfusion, prosthesis complications, and periprosthetic fracture compared to CON-THA. Technology-assisted THA was associated with lower postoperative opioid consumption.

摘要：
■随着技术辅助的全髋关节置换术（THA）体积的增加，需要对机器人辅助（RA）和计算机导航（CN）THA的结果进行表征。这项研究的目的是评估与常规仪器（CON）THA相比，CN-THA和RA-THA后的结果和阿片类药物消耗。
■查询了Premier数据库中所有接受初治的患者，2015-2020年选修THA。患者分为3组：CN，RA,或CON-THA.评估了年度使用趋势。进行单变量和多变量分析以评估术后并发症的90天风险。据报道，术后第0天和第1天（POD）的阿片类药物消耗量为吗啡毫克当量（MME）。
■总的来说，确定了474,707个选修THA（95.7%CON，2.1%CN,2.2%RA。在考虑了混杂因素之后，CN-THA患者假体周围感染（PJI）（aOR：0.55，p<0.001）和脱位（aOR0.45，p<0.001）的风险降低，但与CON-THA相比，输血风险增加（aOR1.97，<0.001）。RA-THA患者脱位风险降低（aOR：0.66，p<0.001），但输血风险增加（aOR1.20，p<0.001），假体断裂(AOR3.88，p<0.001)，和假体周围骨折（aOR1.72，p<0.001）。与CON-THA相比，CN-THA患者的阿片类药物消耗在POD1上较低，RA-THA患者的POD0和2较低。
■CN-THA与PJI和位错率降低有关，但输血率增加而RA-THA与脱位率降低有关，但是输血率增加，假体并发症,与CON-THA相比，假体周围骨折。技术辅助的THA与术后阿片类药物消耗较低相关。
