The safety of simultaneous bilateral total knee arthroplasty (SBTKA) remains controversial. This study aimed to compare the postoperative outcomes of SBTKA versus unilateral total knee arthroplasty (UTKA) performed by a single surgeon at a tertiary teaching hospital in Korea.
629 female patients with total knee arthroplasty (308 patients for SBTKA and 321 for UTKA) performed under combined spinal epidural anaesthesia (CSE) were selected, and their medical records during admission and follow-up visits for a duration of six months after discharge were reviewed.
Although significantly higher incidences of postoperative confusion and hypoxia during hospitalisation and a longer hospital stay were demonstrated in the SBTKA group, the rates of serious postoperative complications, such as myocardial infarction and deep venous thrombosis, were not different between the groups during the hospital stay and six months afterwards. No death associated with the surgery was encountered in both groups.
It was concluded that SBTKA under CSE may be considered to be relatively safe in Korean female patients.
同期双侧全膝关节置换术（SBTKA）的安全性仍存在争议。本研究旨在比较由同一位外科医生在韩国一家三级教学医院进行的 SBTKA 与单侧全膝关节置换术（UTKA）的术后结果。
选择 629 名接受全身麻醉下脊髓-硬膜外联合麻醉（CSE）的女性全膝关节置换术患者（SBTKA 组 308 例，UTKA 组 321 例），回顾其住院期间和出院后 6 个月随访期间的病历记录。
尽管 SBTKA 组术后住院期间出现意识模糊和缺氧的发生率明显更高，且住院时间更长，但两组在住院期间和出院后 6 个月内严重术后并发症（如心肌梗死和深静脉血栓形成）的发生率无差异。两组均未发生与手术相关的死亡。
认为 CSE 下的 SBTKA 对韩国女性患者可能相对安全。
