To characterize patients who underwent simultaneous bilateral total knee arthroplasty (simBTKA) and study the outcomes of surgery along with complication rates.
This is a retrospective study carried out at King Faisal Specialist Hospital and Research Center, Jeddah, Saudi Arabia. The study included patients who had undergone simultaneous bilateral total knee replacement from January 2010 until June 2021.
The median age of our patients was 64 (Q1-Q3: 59-70) years, 76 (13.2%) males and 393 (83.8%) were females. Hypertension was the most common associated comorbidity (56.29%) and primary osteoarthritis was the most common indication of surgery (96.8%). The median duration of surgery was 155 (140-175) minutes and the median duration of hospital stay was 9 (8-11) days. A total of 17 (3.62%) patients needed revision of surgery in a median duration of 265 (112-529) days. The composite endpoint of complications, intensive care unit admission, and blood transfusion occurred in 132 (28.14%) patients. Hospital stay was longer in males (coefficient: 0.11 [0.02-0.19]; =0.01) and in patients with cardiac (coefficient: 0.12 [0.02-0.21]; =0.02), and renal diseases (coefficient: 0.23 (0.06-0.39); =0.01). Cardiac disease was the only factor associated with the composite outcome (odds ratio: 2.25 [1.19-4.24]; =0.01).
Our results suggest simBTKA is a safe procedure with a low complication rate. However, male patients and those with cardiac and renal diseases are at increased risk of post-operative complications and prolonged hospital stay.
对同时行双侧全膝关节置换术（simBTKA）的患者进行特征描述，并研究手术结果及并发症发生率。
这是在沙特阿拉伯吉达的法伊萨尔国王专科医院和研究中心进行的回顾性研究。该研究纳入了 2010 年 1 月至 2021 年 6 月期间行同时双侧全膝关节置换术的患者。
患者的中位年龄为 64（Q1-Q3：59-70）岁，男性 76 例（13.2%），女性 393 例（83.8%）。高血压是最常见的合并症（56.29%），原发性骨关节炎是最常见的手术指征（96.8%）。手术中位时间为 155（140-175）分钟，中位住院时间为 9（8-11）天。共有 17 例（3.62%）患者在中位 265（112-529）天内行翻修手术。132 例（28.14%）患者发生并发症、入住重症监护病房和输血的复合终点事件。男性患者（系数：0.11[0.02-0.19]；=0.01）和患有心脏疾病（系数：0.12[0.02-0.21]；=0.02）及肾脏疾病（系数：0.23[0.06-0.39]；=0.01）的患者住院时间更长。心脏疾病是唯一与复合结果相关的因素（比值比：2.25[1.19-4.24]；=0.01）。
我们的结果表明，simBTKA 是一种安全的手术，并发症发生率低。然而，男性患者和患有心脏及肾脏疾病的患者术后并发症和住院时间延长的风险增加。
