چکیده

Non-contact anterior cruciate ligament (ACL) injury rates are 3-8 times greater for female athletes when compared to their male counterparts. To better understand the biomechanical and neuromuscular risk factors associated with ACL injuries in females, numerous studies have examined sex differences in lower extremity biomechanics during athletic tasks. Studies in this area consistently have reported that females perform athletic maneuvers with decreased knee and hip flexion, increased knee extensor moments and quadriceps activation and greater knee valgus moments when compared to males. Taken together, this biomechanical profile is thought to put females at an increased risk for ACL injury.

The effect of isolated valgus moments on ACL strain during single-leg landing: a simulation study.

Valgus moments on the knee joint during single-leg landing have been suggested as a risk factor for anterior cruciate ligament (ACL) injury. The purpose of this study was to test the influence of isolated valgus moment on ACL strain during single-leg landing. Physiologic levels of valgus moments from an in vivo study of single-leg landing were applied to a three-dimensional dynamic knee model, ...

Influence of sex and maturation on knee mechanics during side-step cutting.

INTRODUCTION Females have been reported to have a three to five times greater incidence of noncontact anterior cruciate ligament injury when compared with their male counterparts. Previous research suggests that physical maturation is one factor that is associated with the development of potentially injurious lower extremity biomechanics in female athletes. PURPOSE The study's purpose was to ...

Sidestep cutting technique and knee abduction loading: implications for ACL prevention exercises.

BACKGROUND Sidestep cutting technique is essential in programmes to prevent anterior cruciate ligament (ACL) injury. A better understanding of how technique affects potentially harmful joint loading may improve prevention programmes. The purpose of this study was to investigate the effect of sidestep cutting technique on maximum knee abduction moments. METHODS Cross-sectional study. Whole-bod...

Background: Women and men significantly differ in the extent of anterior cruciate ligament injury. Based on the evidence, gender especially contributes in non-contact mechanism of anterior cruciate ligament (ACL) injury. The purpose of this study was to compare the movement patterns of the ACL injury risk between men and women during cutting maneuver. Methods: 13 men and 13 women of national...
