Simultaneous bilateral total knee arthroplasty (simBTKA) remains controversial, especially in obese patients. Therefore, this retrospective study compared six month perioperative complications in 313 simBTKA patients. Comparison groups included 139 non-obese patients (BMI < 30), 61 obese patients (BMI = 30-35) and 48 severely obese patients (BMI > 35). Increased BMI was associated with longer tourniquet and surgical times (p < 0.001). However, no differences were found for transfusion (p = 0.288), deep infection (p = 0.971), pulmonary embolism (p = 0.454), or deep vein thrombosis (p = 0.670). Increased BMI was, therefore, not associated with greater post-operative complications and should not necessarily contraindicate simBTKA.
同期双侧全膝关节置换术（simBTKA）仍存在争议，尤其是在肥胖患者中。因此，这项回顾性研究比较了313例simBTKA患者的围手术期六个月并发症情况。比较组包括139例非肥胖患者（BMI < 30）、61例肥胖患者（BMI = 30 - 35）和48例重度肥胖患者（BMI > 35）。BMI的增加与止血带使用时间和手术时间延长相关（p < 0.001）。然而，在输血（p = 0.288）、深部感染（p = 0.971）、肺栓塞（p = 0.454）或深静脉血栓形成（p = 0.670）方面未发现差异。因此，BMI增加与术后并发症增加无关，不一定是simBTKA的禁忌证。
