The use of a closed-suction drain in total knee arthroplasty: a prospective, randomized study / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To determine the value of using a closed-suction drain in cemented knee arthroplasty.</p><p><b>METHODS</b>One hundred patients were prospectively randomized into two groups, one group underwent cemented total knee replacement with a single deep closed-suction drain, and the other group (n = 50) no drain.</p><p><b>RESULTS</b>The total blood loss was significantly greater in those with a drain although those without lost more blood into the dressings. There was no statistical difference in the postoperative swelling or pain score, ecchymosis, deep vein thromboses (DVT), time at which flexion was regained or the incidence of infection at a minimum of two years after surgery in the two groups.</p><p><b>CONCLUSION</b>There is no evidence to support the use of a closed-suction drain in cemented knee arthroplasty.</p>
