The Relationship Between Acl Injuris of Elite Athletic Females and Their Body Mechanic

Women who participate in high-risk sports showed 2-8 times more ACL injury than males athletes. The purpose of this research was to study the relationship between postural malalignment and ACL injury in certain skeletal landmarks. Twenty ACL - injured females (age 24.90±5.75 yr, height 167.05±6.58 cm, mass 60.88±5.58 and athletic experience 7.70±4.41) and 20 non-injured females (age 24.80±5.59 yr, height 166.15±6.39 cm, mass 60.20±6.08 and athletic experience 7.00 ±3.69) were matched by age, sport and involved limb participated in this study. Subjects were assessed for navicular drop, dorsiflextion, tibial torsion, Q angle, anteversion, knee recurvatum; hip internal and external rotation rang of motion, true and apparent leg length discrepancies and general joint laxity. Data were analyzed using by and logistic regression tests (p<.05). Results showed significant relationship between ACL injury with navicular drop, knee recurvatum and tibial torsion. Also general joint laxity and navicular drop were found to be statistically significant predictive of ACL injury history. Based on the results of this retrospective study the identifying and correcting of such these biomechanical and ana-tomical factors which predispose the ACL to injury are necessary.
