We hypothesised that the higher ATT, lower hamstring\u2010to\u2010quadriceps (HQ) ratio, and higher flexion peak torque influenced by semimembranosus would be associated with ramp lesions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>One hundred and twenty\u2010one patients who underwent anterior cruciate ligament (ACL) reconstruction were retrospectively evaluated. Clinical evaluation included ATT of the contralateral uninjured limb measured using a KT\u20101000 arthrometer, the knee flexor and extensor muscle strength of the contralateral uninjured limb at 60\u00b0\/s and 180\u00b0\/s of an angular velocity measured using an isokinetic dynamometer, and HQ ratio at 60\u00b0\/s and 180\u00b0\/s during the preoperative state. Binary stepwise logistic regression analysis was performed to evaluate the risk factors of ramp lesions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Ramp lesions were found in 27 cases of ACL injuries (27\/121, 22.3%). Male sex (odds ratio [OR], 2.913; 95% confidence interval [CI], 1.090\u20137.787; P\u2009=\u20090.033), longer time between injury to surgery (OR, 2.225; 95% CI, 1.074\u20134.608; P\u2009=\u20090.031), and higher ATT in the contralateral uninjured limb (OR, 1.502; 95% CI, 1.046\u20132.159; P\u2009=\u20090.028) were indicated as the independent risk factors of the presence of ramp lesion associated with an ACL injury.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Male sex, longer period from injury to surgery, and higher ATT in the contralateral uninjured limb were significantly associated with ramp lesion. These findings are advantageous for identifying patients with a greater risk of developing a ramp lesion with an ACL injury in the clinical setting.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
