Prolongation of operation time due to registration and pin insertion has been reported with robotic-assisted total knee arthroplasty (RATKA), and there has been concern about an increase in the postoperative incidence of deep vein thrombosis (DVT). In this study, we compared the incidence of DVT after RATKA with that after conventional manual TKA (mTKA).
This consecutive retrospective series included 141 knees that underwent primary TKA using the Journey II system. The CORI robot was used. There were 60 RATKAs and 81 mTKAs. Doppler ultrasound was performed in all patients on postoperative day 7 to determine whether DVT was present.
The operation time was longer in the RATKA cohort (99.5 min vs 78.0 min, p < 0.001). The overall incidence of DTV was 43.9% (62/141 knees), all of which were asymptomatic. There was no significant difference in incidence of DVT between RATKA and mTKA (50.0% vs 39.5%, p = 0.23). Use of the robot did not affect the incidence of DVT following TKA (odds ratio 1.02, 95% confidence interval 0.40-2.60; p = 0.96).
The incidence of DVT was not significantly different between RA-TKA and mTKA. Multiple logistic regression indicated that RATKA is not associated with increased risk of postoperative DVT.

据报道，机器人辅助全膝关节置换术（RATKA）因注册和插入钢针导致手术时间延长，人们一直担心术后深静脉血栓形成（DVT）的发生率会增加。在本研究中，我们比较了RATKA术后与传统手动全膝关节置换术（mTKA）后DVT的发生率。
本连续回顾性系列研究纳入了141例使用Journey II系统进行初次全膝关节置换术的膝关节。使用了CORI机器人。其中有60例RATKA和81例mTKA。所有患者在术后第7天进行多普勒超声检查，以确定是否存在DVT。
RATKA队列的手术时间更长（99.5分钟对78.0分钟，p<0.001）。DVT的总体发生率为43.9%（62/141膝），均为无症状性。RATKA和mTKA之间DVT的发生率没有显著差异（50.0%对39.5%，p=0.23）。使用机器人并不影响全膝关节置换术后DVT的发生率（优势比1.02，95%置信区间0.40-2.60；p=0.96）。
RA-TKA和mTKA之间DVT的发生率没有显著差异。多元逻辑回归表明，RATKA与术后DVT风险增加无关。
