Prospective cohort study of 517 patients undergoing 638 total knee replacements at HSS (1974–1979), using routine postoperative venography and perfusion lung scanning to determine DVT incidence, identify risk factors, and compare prophylactic regimens.
When performing TKA — unilateral or bilateral. Assume your patient is at high DVT risk regardless of their comorbidity profile, because no individual risk factor predicts thrombosis in this population; routine prophylaxis is warranted for all.
Don't rely on clinical exam to exclude DVT: with a >90% false-negative rate, a symptom-free leg means nothing.
