Abstract：
UNASSIGNED: The purpose of this study was to assess if subcutaneous fat (SCF) or BMI is a predictor of surgical complications and patient reported outcomes in patients undergoing robotic-assisted total hip arthroplasty (THA).
UNASSIGNED: Patients who underwent robotic-assisted primary THAs at one institution between 2018 and 2020 were included in this retrospective cohort study. Prior to surgery, computed tomography (CT) was used to measure SCF in the posterolateral quadrant of the hip. SCF was measured 3 centimeters (cm) proximal to the greater trochanter (PGT) and 3 cm inferior to the distal tip of the greater trochanter (DGT).Measurements were normalized to the size of the patient\'s bony anatomy by dividing the subcutaneous fat area measurement by the transverse diameter of the femur 10 cm inferior to the tip of the greater trochanter. Patients were divided into quintiles determined by SCF distribution around the mean (groups 1-5) and BMI (BMI<25, BMI 25-29.9, BMI 30-34.9, BMI 35-39.9, and >40). Ninety day outcomes and PROMIS (Patient Reported Outcome Measures Information System) scores were acquired from the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) database preoperatively, at 14-112 days post-operative and at the latest follow up.
UNASSIGNED: There were 175 patients identified with a mean age of 63.83 years (range 27-89) and a mean BMI of 30.73kg/m2 (range 18.2-48.4). Interclass correlation coefficient was greater than 0.9 in all PGT, DGT, and GT measurements. Analysis of Variance (ANOVA) found there was a significantly shorter time from incision to closure in quintiles 1 and 3 when compared to the SCF quintile 5 (p<0.05) and that there was a significantly shorter time from incision to closure in BMI categories 1, 2, and 3 when compared to BMI category 5 (BMI > 40). There were no differences between SCF and BMI as predictive of length of stay, transfusion status, infection, or PROMIS scores.
UNASSIGNED: It can be concluded that hip SCF on axial CT images can reliably measure SCF and is predictive of time from incision to closure, but it does not show a significant difference in predicting the length of stay, infection, or PROMIS scores when compared to BMI.

摘要：
■本研究的目的是评估接受机器人辅助全髋关节置换术（THA）的患者中，皮下脂肪（SCF）或BMI是否是手术并发症和患者报告结果的预测指标。
■在2018年至2020年期间在一个机构接受机器人辅助初级THA的患者被纳入这项回顾性队列研究。手术前,计算机断层扫描(CT)用于测量髋关节后外侧象限的SCF.SCF在大转子（PGT）近端3厘米（cm）和大转子（DGT）远端3厘米以下。通过将皮下脂肪面积测量值除以大转子尖端下方10cm的股骨横向直径，将测量值标准化为患者骨解剖结构的大小。根据SCF分布在平均值（第1-5组）和BMI（BMI<25，BMI25-29.9，BMI30-34.9，BMI35-39.9和>40）确定患者分为五分位数。90天的结果和PROMIS（患者报告的结果测量信息系统）评分从密歇根关节成形术注册协作质量倡议（MARCQI）数据库术前获得，术后14-112天及最新随访。
■有175名患者，平均年龄为63.83岁（范围27-89），平均BMI为30.73kg/m2（范围18.2-48.4）。所有PGT的类间相关系数均大于0.9，DGT,和GT测量。方差分析（ANOVA）发现，与SCF五分位数5相比，五分位数1和3从切口到闭合的时间明显较短（p<0.05），并且与BMI类别5（BMI>40）相比，BMI类别1、2和3从切口到闭合的时间明显较短。SCF和BMI对住院时间的预测没有差异，输血状态,感染,或PROMIS分数。
■可以得出结论，轴向CT图像上的髋关节SCF可以可靠地测量SCF，并且可以预测从切口到闭合的时间，但是在预测住院时间上没有显着差异，感染,或与BMI相比的PROMIS评分。
