title: Graded compression stockings for prevention of deep-vein thrombosis after hip and knee replacement.
abstract: We performed a prospective, randomised controlled trial in 177 patients who were having either total hip or knee replacement, to evaluate the use of both above- and below-knee graded compression stockings in the prevention of deep-vein thrombosis (DVT). With above-knee stockings, we found no significant reduction of the overall, proximal or major calf (> 5 cm) DVT rates. With below-knee stockings, the overall thrombosis rate was similar to that of the control group but the stockings appeared to have altered the pattern of thrombosis. Patients who had total hip replacement and wore below-knee stockings had a significantly higher rate of proximal or major calf DVT (p = 0.03). This pattern was reversed in patients with total knee replacement who developed a significantly lower rate of proximal or major calf DVT with below-knee stockings (p < 0.05). Our results showed that, with the exception of below-knee stockings in knee replacement patients, graded compression stockings were ineffective in preventing DVT after hip or knee replacement surgery.
