Key result
Preoperative hemoglobin ≥14 g/L (OR 2.4; 95% CI 1.2-4.6) and bilateral procedures (OR 7.2; 95% CI 1.3-39.6) were significant risk factors for symptomatic pulmonary embolism after total knee arthroplasty.

Preoperative hemoglobin ≥14 g/L and bilateral procedures are significant risk factors for symptomatic pulmonary embolism after total knee arthroplasty despite warfarin prophylaxis.

Are preoperative hemoglobin levels and bilateral procedures associated with an increased risk of symptomatic pulmonary embolism in patients undergoing total knee arthroplasty?
Odds Ratio: 2.4 (95% CI 1.2–4.6)
Preoperative hemoglobin ≥14 g/L and bilateral procedures are significant risk factors for symptomatic pulmonary embolism after total knee arthroplasty despite warfarin prophylaxis.
Michael Messieh (1999) conducted a case-control in Osteoarthritis (n=124). Preoperative hemoglobin ≥14 g/L vs. Preoperative hemoglobin <14 g/L was evaluated on Symptomatic pulmonary embolism (OR 2.4, 95% CI 1.2-4.6). Preoperative hemoglobin ≥14 g/L (OR 2.4; 95% CI 1.2-4.6) and bilateral procedures (OR 7.2; 95% CI 1.3-39.6) were significant risk factors for symptomatic pulmonary embolism after total knee arthroplasty.
