Knee injury and lower extremity deep venous thrombosis / 中华普通外科杂志

ABSTRACT

Objective To explore the relation between lower extremity deep venous thrombosis and knee injury.Methods 100 knee injury patients were operated on in our department.The difference of incidence rates of DVT,the thrombus location and incidence rates of DVT before and after operation in the two groups was compared.There were no fatal pulmonary embolism occurring in either group.Results The incidence rate of DVT in tibial plateau fracture group was 52％,that in patellar fracture was 30％ (P ＜ 0.05).DVT incidence rate of popliteal,pretibial,posterior tibial vein thrombosis in group of tibial plateau fracture was higher than that in group of patellar fracture (P ＜ 0.05),while there was no significant difference in postoperative thrombosis between the two groups(P ＞ 0.05).Conclusions There is a high incidence rate of DVT in knee joint injury.Which is closely related to the position of fracture and limb immobilization.
