Women are more prone to anterior cruciate ligament (ACL) injury during cutting sports than men. The purpose of this study was to examine knee kinematic and ground reaction forces (GRF) differences between genders during cutting. Male and female athletes performed cutting trials while force platform and video data were recorded (180 Hz). Differences (p ≤ .05) were observed between groups for knee flexion at contact and GRF at maximum knee flexion. Women averaged 5.8° less flexion at contact and 1.0 N· (kg·m·s −1 ) −1 greater GRF at maximum flexion. Knee range of motion and peak GRF variables were not significantly different, but women had greater values. Women exhibited technique characteristics believed to increase ACL injury risk, but men exhibiting similar characteristics were also observed and could also be at risk.
Keywordsanterior cruciate ligament; cutting; female athletes; knee injury Female athletes are at greater risk of noncontact anterior cruciate ligament (ACL) injuries than male athletes in sports involving sudden deceleration, landing, and cutting (Arendt & Dick, 1995;Dehaven & Lintner, 1986;Gray et al., 1985;Moeller & Lamb, 1997;Zelisko, Noble, & Porter, 1982). Numerous studies have investigated the nature of ACL injuries and possible explanations for the differences in injury rates between genders. Several causes have been suggested, including anatomical, physiological, and biomechanical characteristics, such as differences in intercondylar notch configuration (Anderson, Lipscomb, Liudahl, & Addlestone, 1987;LaPrade & Burnett, 1994;Souryal & Freeman, 1993), inherent joint looseness and ligament laxity (Weesner, Albohin, & Ritter, 1986), lower limb alignment (e.g., Qangle, tibial Please address all correspondence concerning this article to C.

Movement technique is a complex factor, as it not only reflects many of the other preceding anatomical, physiological, and internal biomechanical characteristics, but it is also a function of volitional control and perceptual influences. It is probable that the injury differences among individuals are a result of a multifactorial interaction among several characteristics that might or might not be gender related, and differences in many of these characteristics manifest themselves as dif...
