인공 슬관절 전치환술에서 음압 배액법과 특수한 술기를 이용한 일반 배액법의 효과 비교

Abstract

The aim of this study is to compare the results (effectiveness) between the group used closed suction drainage and the group used conventional drainage with specific technique during 48 hours after total knee arthroplasty. We analyzed the thigh circumference, ecchymosis, wound infection, transfusion amount, knee score and range of motion in 100 cases (100 patients) underwent total knee replacement from October 2004 to April 2008 in retrospectively. Fifty cases of them (group I) were inserted hemo vac and the other group (group II) were inserted conventional drain (Penrose drain). The average thigh circumference in group I was 40.6 cm (preoperative), and 44.6 cm (postoperative), in group II was 40.3 cm (preoperative) and 44.8 cm (postoperative). Group I was more higher than Group II in incidence of ecchymosis (Group I:50% vs Group II:24%). However, the final result of knee score and range of motion of knee joint were not affected significantly by nonuse of closed suction drainage. There were no infection sign in both groups. This clinical comparision of closed suction drainage group and conventional drainage group after total knee arthroplasty was not significantly different in wound healing, clinical and rehabilitation course. The short term use of conventional drainage (Penrose drain) with specific technique can be one of useful method after primary total knee arthroplasty.
