WEDNESDAY, April 5, 2017 (HealthDay News) -- Hip or knee replacement patients who smoke are at increased risk for infections requiring repeat surgery, researchers report.

They analyzed data from more than 15,000 patients who underwent either total hip or knee replacements between 2000 and 2014. The investigators found that the overall risk of repeat surgery for infections within 90 days was only 0.71 percent.

However, the risk was 1.2 percent for current smokers, compared with 0.56 percent for nonsmokers. After adjusting for other factors, the researchers concluded that current smokers' risk was 80 percent higher than nonsmokers and former smokers.
