Biomechanical characteristics of the knee joint in female athletes during tasks associated with anterior cruciate ligament injury

Comparison of Drop Jumps and Sport-Specific Sidestep Cutting

“…3,4,14,15 In sidestep cutting the athletes had lower 169 knee flexion angles and higher knee valgus and internal rotation angles at IC and at maximum. The 170 knee joint moments were higher in all three planes for the sidestepping movement.…”

“…The main 74 differences found between drop jumps and sidestep cutting are lower knee flexion angles and higher 75 knee valgus angles and knee abduction moments in sidestep cutting. 3,4,14 One study has done a 76 factor analysis of drop jumps and sidestep cutting. 15 They found poor correlation between frontal 77 plane measures in drop jumps and unanticipated cutting.…”

Knee kinematics and kinetics during shuttle run cutting: Comparison of the assessments performed with and without the point cluster technique

“…The knee joint kinematics during high-risk movements associated with non-contact ACL injuries (i.e., landing and cutting) have been examined using PCT (Ishii et al, 2009;Nagano et al, 2007Nagano et al, , 2009. Although knee joint kinetic analysis is useful for studying the mechanisms of non-contact ACL injuries, few studies (Ishii et al, 2009) have used PCT to determine the knee joint kinetics during high-risk movements.…”

The Effect of Foot Landing Type on Lower-extremity Kinematics, Kinetics, and Energy Absorption during Single-leg Landing

“…However, over 70% of ACL injuries occur during single-leg landing or change-of-direction movements (Boden et al, 2009;Nagano, Ida, Akai & Fukubayashi, 2009). Even though single-leg landing presents a higher risk of injury than double-leg landing (Nagano et al, 2009), there have not yet been any studies on the effects of landing type on biomechanical characteristics during single-leg landing.…”

“…However, over 70% of ACL injuries occur during single-leg landing or change-of-direction movements (Boden et al, 2009;Nagano, Ida, Akai & Fukubayashi, 2009). Even though single-leg landing presents a higher risk of injury than double-leg landing (Nagano et al, 2009), there have not yet been any studies on the effects of landing type on biomechanical characteristics during single-leg landing. Hence, the present study compared lower-extremity kinematics, kinetics, and joint work during single-leg landing across different landing types, with the aim of examining differences in the biomechanical characteristics of the lower-extremity joints between forefoot and rearfoot landing.…”
