Abstract:
PURPOSE: To compare the efficacy and availability of foot pump and active ankle exercise for preventing deep vein thrombosis after total knee arthroplasty with hemodynamic evaluation using a color doppler duplex ultrasonography. MATERIALS AND METHODS: Thirty-six patients who underwent total knee arthroplasty between Oct. 2005 and Apr. 2006 were enrolled in this study. Retrospective analysis of 36 patients(Group 1 - foot pump after TKA, 18; Group 2-passive ankle exercise, 18) was conducted and all patients underwent color doppler duplex ultrasonography preoperatively and postoperative 7 to 14 days at femoral, popliteal and calf vein and the hemodynamic status was assessed. RESULTS: The mean baseline velocity was decreased postoperatively in both group, at all veins, but the mean peak velocity was increased only in Group. In Group 1, mean flow ratio was increased, but in Group 2, mean flow ratio was decreased except femoral vein. There were significant differences between Group 1 and Group 2(p<0.05). CONCLUSION: This study demonstrated that foot pump may be more effective than active ankle exercise in preventing postoperative deep vein thrombosis due to more increased venous flow rate and foot pump may be more compliable than active ankle exercise due to less painful, more convenient, so foot pump can be one of the available method for preventing DVT after total knee arthroplasty.
