Low-molecular-weight heparin versus compression stockings for thromboprophylaxis after knee arthroscopy: a randomized trial.

Camporese et al. (2008) conducted an RCT in Knee arthroscopy (n=1,761). Low-molecular-weight heparin (LMWH) vs. Full-length graduated compression stockings was evaluated on Combined incidence of asymptomatic proximal deep venous thrombosis, symptomatic venous thromboembolism, and all-cause mortality (absolute difference 2.3 percentage points, 95% CI 0.7 to 4.0 percentage points, p=0.005). Prophylactic low-molecular-weight heparin for 1 week reduced deep venous thrombosis, thromboembolism, or death compared with compression stockings (0.9% vs 3.2%; P=0.005).
