The prevalence of medial and lateral meniscal tears was 32.0% (266\u00a0knees) and 26.5% (220\u00a0knees), respectively. Significant factors that influenced the prevalence of medial meniscal injuries were age [odds ratio (OR) 1.03; <jats:italic>P<\/jats:italic>\u2009=\u20090.000], side\u2010to\u2010side differences in instrumented anterior knee laxity before surgery (OR 1.12; <jats:italic>P<\/jats:italic>\u2009=\u20090.002), duration between injury and surgery (\u2265\u200912\u00a0months) (OR 1.86; <jats:italic>P<\/jats:italic>\u2009=\u20090.023), and pivot shift test grade (OR 1.36; <jats:italic>P<\/jats:italic>\u2009=\u20090.014). Significant factors of lateral meniscal injury were side\u2010to\u2010side differences in anterior knee laxity before surgery (OR 1.12; <jats:italic>P<\/jats:italic>\u2009=\u20090.003) and the male sex (OR 1.50; <jats:italic>P<\/jats:italic>\u2009=\u20090.027).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Greater anterior knee laxity, age, a longer duration between injury and surgery, and a higher pivot shift test grade predicted medial meniscal injury.

In patients with ACL injuries, the importance of side\u2010to\u2010side differences in anterior knee laxity should be rediscovered from the viewpoint of meniscal
