Following major joint surgery with short-term LMWH prophylaxis, the overall incidence of confirmed clinical pulmonary embolism was 1.3%, with the risk remaining high for up to 2-3 months after hip surgery.

The incidence of clinical pulmonary embolism remains elevated for weeks to months after major joint surgery despite standard in-hospital LMWH prophylaxis, highlighting the potential need for extended, procedure-specific thromboprophylaxis.
Dahl et al. (2003) conducted a cohort in Major joint surgery (total hip replacement, total knee replacement, or nailed hip fracture) (n=3,954). Major joint surgery with short-term LMWH prophylaxis was evaluated on Incidence of radiologically-confirmed, clinical pulmonary embolism (95% CI 0.9-1.6). Following major joint surgery with short-term LMWH prophylaxis, the overall incidence of confirmed clinical pulmonary embolism was 1.3%, with the risk remaining high for up to 2-3 months after hip surgery.
