DANESHMANDI, H.; AZHDARI, F.; SAKI, F.; DANESHMANDI, M. S. The study of lower extremity alignment in athletes with and without acl reconstruction. Brazilian Journal of Biomotricity. v. 5, n. 4, p. 248-254, 2011. The purpose of this research was to examine the difference of lower extremity alignment between subjects with and without ACL reconstruction. 20 ACL–injured males (age: 26.5±3.36 yr; height: 178.07±5.43 cm; weight: 77.5±7.72 kg; athletic experience: 7.70±4.41 yr) and 20 non-injured males (age 25.7±2.84 yr, height 178.05±4.47 cm, weight 73.65±8.73 and athletic experience: 7.00 ±3.69 yr) were matched by age, sport and involved limb participated in this study. Subjects were assessed for navicular drop, T-F angle, Q angle, anteversion, knee recurvatum, hip internal and external rotation range of motion, true and apparent leg length. The results showed significant difference between pronation, T-F angle, Q angle, anteversion and hip external rotation in the two groups (p≤0.05).Based on results of this retrospective study, identifying such biomechanical and anatomical factors, which predispose the ACL to injury, are necessary.
