This is a local, prospective, multicenter, non-interventional, observational study. Primary objective is to describe how in "real life" thromboprophylaxis is carried out after the discharge from a hospital in the patients who undergo elective knee and hip replacement and who receive Xarelto during hospitalization.

Inclusion Criteria:

• Male and female patients ≥ 18 years old
• Elective hip or knee replacement
• Planned VTE prevention with Xarelto
• Written informed consent
• The decision for treatment type and duration is taken by the investigator and is made before inclusion into the study.

Exclusion Criteria:

• Contraindications for the use of Xarelto in accordance with the effective instruction
• Any reasons of medical and non-medical character, which in the opinion of the physician can hamper participation of the patient in NIS, including a potentially low compliance, impossibility of making the final visit due to distant place of residence of the patient.

The patients will be treated according to the routine practice. All the patients meeting the criteria of inclusion and exclusion to whom administration of Xarelto is indicated are fit for participation in this non-interventional study.
