[Prevention of deep vein thrombosis in total knee replacement--current status of therapy in orthopedie and trauma departments in Germany]. / Thromboseprophylaxe in der Knieendoprothetik. Stand der Therapie an deutschen orthopädisch-traumatologischen Kliniken.

ABSTRACT

INTRODUCTION: Symptomatic deep vein thrombosis is a serious complication after total knee arthroplasty, with a risk of about 4-5% despite prevention with herparin. Aim of the current study was to find out about the actual status of thrombosis prophylaxis in Germany after total knee replacement. MATERIAL AND METHODS: In a countrywide survey 470 German trauma and orthopaedic surgery departments were asked about their prophylactic procedures addressing deep vein thrombosis after total knee replacement. RESULTS: 98% perform prevention of thrombosis with low-molecular-weight heparin, 2% use unfractioned heparin. Low-molecular-weight heparin is applicated in standard doses in 48% and in 44% according to patient's weight. In 82% the prophylaxis is begun the night before surgery. The therapy is carried out for 4.7 weeks in mean. 96% use graduated compressions stocking as additional therapeutic option. CONCLUSION: Our survey shows that most of the surgeons perform prevention of deep vein thrombosis according to the official guidelines.
