The aim of this retrospective cohort study was to investigate the effect of BMI on 1-year functional outcome, quality of life (QoL) and rate of postoperative complications after shoulder arthroplasty. We included 121 patients (59 men and 62 women) with primary osteoarthritis (OA) who underwent anatomical or reverse total shoulder arthroplasty (TSA or rTSA) between 2011 and 2016. Age, sex, preoperative BMI, preoperative medical status using American score of anesthesiologists (ASA) class, type of prosthesis, preoperative and 1-year postoperative functional outcome using the Constant score and quality of life (QoL) using the EQ-5D as well as postoperative complication rate were documented. Patients were divided into three groups based on their BMI, group 1 (normal weight, BMI <25), group 2 (overweight, BMI 25-30) and group 3 (obese, >BMI 30). All three groups were comparable regarding age, sex and ASA class, preoperative Constant score EQ-5D. We found significant improvement of the Constant score and EQ- 5D at 1-year postoperative follow-up, regardless of BMI (p<0.05). Comparing the three groups, we found no significant differences among them in 1-year Constant score, EQ-5D or postoperative rate of complications. This study showed that BMI did not affect functional outcome, QoL and postoperative complication rate in TSA. These results can help physicians and patients to make reasonable perioperative expectations and planning.
这项回顾性队列研究的目的是调查体重指数（BMI）对肩关节置换术后1年功能结局、生活质量（QoL）和术后并发症发生率的影响。我们纳入了121例原发性骨关节炎（OA）患者（59例男性和62例女性），他们在2011年至2016年间接受了解剖型或反式全肩关节置换术（TSA或rTSA）。记录了患者的年龄、性别、术前BMI、使用美国麻醉医师评分（ASA）分级的术前医疗状况、假体类型、使用Constant评分的术前和术后1年功能结局以及使用EQ-5D的生活质量（QoL）以及术后并发症发生率。根据BMI将患者分为三组，第1组（正常体重，BMI<25），第2组（超重，BMI 25-30）和第3组（肥胖，BMI>30）。所有三组在年龄、性别和ASA分级、术前Constant评分、EQ-5D方面具有可比性。我们发现在术后1年随访时，无论BMI如何，Constant评分和EQ-5D均有显著改善（p<0.05）。比较三组，我们发现它们在术后1年的Constant评分、EQ-5D或并发症发生率方面没有显著差异。这项研究表明，BMI不影响TSA的功能结局、QoL和术后并发症发生率。这些结果可以帮助医生和患者做出合理的围手术期预期和规划。
