Answer: 2
The JBJS article quoted is a meta analysis looking at studies that compared patients managed with closed-suction drainage systems and those managed without a drain following elective hip and knee arthroplasty. There was no significant difference between drain and no drain with respect to wound infection, wound hematoma, reoperations for wound complications, limb-swelling, venous thrombosis, or hospital stay. A drained wound was associated with a significantly greater need for transfusion. So choice 2 is the correct answer.
