To investigate the incidence of deep vein thrombosis (DVT) following total knee arthroplasty in an Asian population.
A prospective study of 149 consecutive cases of total knee arthroplasty done for osteoarthritis was conducted over a 5-year period. All patients underwent duplex ultrasonographic assessment of the lower limbs within the first postoperative week.
The incidence of proximal DVT was found to be 4.38% in this study. Symptomology was statistically significant in predicting the presence of proximal DVT in all cases. General anaesthesia was associated with a statistically significant-higher incidence of DVT as compared with regional anaesthesia. There was a significant association between a sedentary lifestyle and the development of DVT.
The incidence of proximal DVT in Asian patients after total knee arthroplasty is higher than that previously reported for this demographic group.
调查亚洲人群全膝关节置换术后深静脉血栓形成（DVT）的发生率。
对5年间连续进行的149例因骨关节炎行全膝关节置换术的病例进行前瞻性研究。所有患者在术后第一周内接受双功超声对下肢的评估。
本研究中近端DVT的发生率为4.38%。在所有病例中，症状学在预测近端DVT的存在方面具有统计学意义。与区域麻醉相比，全身麻醉与DVT发生率显著较高相关。久坐的生活方式与DVT的发生之间存在显著关联。
亚洲患者全膝关节置换术后近端DVT的发生率高于此前该人群组的报道。
