Abstract
A retrospective review of 299 total knee arthroplasties performed between 1973 and 1983 revealed 170 knees in which postoperative suction drainage was used and 129 knees in which drains were not used. Comparison between these two groups revealed no statistically significant difference in wound problems, postoperative temperatures, or resulting range of motion. However, blood transfusions were given more than twice as often to the patients whose knees were drained (39% compared to 16%, p <.01). The drained group also had a greater decrease in hemoglobin than the nondrained group (3.1 gm compared to 2.6 gm, p <.01). In a review of these patients, no advantage was found for the use of postoperative suction drainage in the uncomplicated total knee arthroplasty.
