Purpose

The objectives of the study are:

o Objective ultrasound: Determine the presence or absence of subclinical DVT in practicing ultrasound-Doppler Day7 and Day35, patients who underwent TKA or THA

o Clinical objective To evaluate the efficacy and tolerability clinical Enox ® in these patients compared with the original drug Lovenox ®.

Primary Outcome Measures:

Presence or absence of ultrasound findings in favor of asymptomatic DVT [ Time Frame: Day 7 and 35 ]
After orthopedic surgery, patients are put under LMWH thromboprophylaxis based but some patients may be carrying an asymptomatic DVT. so we'll try the distal venous thrombosis rate in these patients using Doppler ultrasound.

Secondary Outcome Measures:

To evaluate the efficacy and tolerability clinical Enox ® in these patients. [ Time Frame: 3 months ]
Criteria for evaluating the effectiveness of Enox ®:
- Onset or without clinical signs of deep vein thrombosis in clinical postoperative
- Onset or without clinical signs of pulmonary embolism after surgery
