Summary
Brief summary
The purpose of this study is to learn if apixaban can prevent blood clots in the leg (deep
vein Thrombosis [DVT]) and lung (pulmonary embolism [PE]) that sometimes occur after knee
replacement surgery and to learn how apixaban compares to enoxaparin (Lovenox®) for
preventing these clots. The safety of apixaban will also be studied.
