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 hip replacement surgery and to learn how apixaban compares to enoxaparin (Lovenox®) for preventing these clots. The safety of apixaban will also be studied
