Our objective was to compare outcomes (anesthesia time, total operative time, tourniquet time, duration of hospital stay, 90-day complication rate, and transfusion rates) of patients with total knee arthroplasty (TKA) who underwent bariatric surgery before or after TKA. One hundred twenty-five patients were included: TKA before bariatric surgery (group 1; n = 39), TKA within 2 years of bariatric surgery (group 2; n = 25), and TKA more than 2 years after bariatric surgery (group 3; n = 61). Patients with TKA more than 2 years after bariatric surgery had shorter anesthesia and total operative and tourniquet times than other groups; differences were significant between groups. Ninety-day complication and transfusion rates approached but did not meet statistical significance. Ninety-day complication rates and duration of hospital stay did not differ significantly between the 3 groups. The level of evidence was level II (cohort study).
我们的目的是比较接受过减重手术的全膝关节置换术（TKA）患者与未接受过减重手术的 TKA 患者的手术结局（麻醉时间、总手术时间、止血带时间、住院时间、90 天并发症发生率和输血率）。共纳入 125 例患者：TKA 前接受减重手术（组 1，n=39）、TKA 后 2 年内接受减重手术（组 2，n=25）和 TKA 后 2 年以上接受减重手术（组 3，n=61）。与其他两组相比，TKA 后 2 年以上接受减重手术的患者麻醉时间、总手术时间和止血带时间更短，组间差异具有统计学意义。90 天并发症发生率和输血率接近但未达到统计学意义。三组之间 90 天并发症发生率和住院时间无显著差异。证据水平为 II 级（队列研究）。
