Venous thromboembolism after lower limb arthroplasty: is chemical prophylaxis still needed?

Background: Venous thromboembolism (VTE) is a significant complication of lower limb arthroplasty. The National Institute for Health and Care Excellence recommends routine use of chemical and mechanical prophylaxis to prevent VTE. Our high-volume, elective, arthroplasty unit adopted this guidance in 2008.

Bilateral sleeve fracture of the inferior poles of the patella in a healthy child: case report and review of the literature.
