Abstract

Background and Aim: Changes in lower extremity alignment are considered as a risk factor for the injuries in this area together with Q angle. The purpose of the present study was to examine the relationship and affecting anatomical factors of lower extremity alignment on the Q angle.
Materials and Methods: A total of 120 male students from Tehran University participated in the study and their lower extremity alignments were investigated in these factors: hip anteversion, internal and external rotation of the hip, valgus and varus of knee, hyperextension of the knee, tibia rotation, tibiavara, and arch index.
Results: The results showed that the variables of plantar arch index, varus and valgus of knee, hip anteversion, and tibial torsion had maximum effect on the predicted value of the Q angle (p≤0/05) and the most influence was found to be respectively related to plantar arch index, anteversion of hip, tibial torsion, and varus and valgus of knee.
Conclusion: The results showed that the changes in the lower extremity anatomical alignment can affect the amount of Q angle. Among the variables studied, the plantar arch index was noted to have the greatest impact due to the influence of the three-point constituent of this angle. Changes in this angle can put the person at the risk of various injuries in the segments of the lower limb.
