High asymptomatic DVT rates without prophylaxis after TKA may inform risk assessment; leaves open optimal contemporary prophylaxis strategies for randomized evaluation.
What is the prevalence of deep-vein thrombosis detected by routine venography after total hip and knee replacement without prophylaxis?
In patients undergoing total joint arthroplasty without prophylaxis, routine venography reveals a high prevalence of asymptomatic DVT, particularly after knee replacement (66%).
Clarke et al. (1997) studied this question.
