To evaluate the effectiveness of closed wound drainage in shoulder sur
gery, 300 patients were enrolled in a prospective randomized study. Th
ree operations were studied: rotator cuff repair, anterior reconstruct
ion For instability, and arthroplasty. One hundred patients were inclu
ded in each group. All patients were evaluated For wound hematoma, inf
ection, variation in postoperative rehabilitation caused by wound prob
lems, and length of hospital stay. No statistical difference was Found
between the patients whose wounds were drained and those whose wounds
were not drained. This finding existed within each category. Our data
do not support the routine use of closed wound drainage in elective s
houlder surgery.
