Abstract
Background: Quadriceps angle (Q-angle) and Tibiofemoral angle (TF-angle) are both considered in assessing the proper alignment of the knee joint when assessed from frontal plane. Both are used for assessment of knock-knees and bow-leg deformities. Objectives: To investigate the interrelationship among Quadriceps angle and Tibiofemoral angle, compare the effects of dominancy on both angles, find the difference in q-angle/tf-angle with respect to dominance, sports’ practice and dominance. Design: An observational design (cross-sectional study). Settings: The assessment procedures were conducted at the Faculty of Physical Therapy, Cairo University. Participants: One-hundred and fifty adolescent, age ranged from 12 to 18 years represented two groups; group A (Athletic group) included four subgroups of different sport activities, and group B (Non-athletic group). Outcome measures: Both Quadriceps angle and Tibiofemoral angle were measured through computerized photogrammetry. Results: This study showed a statistically significant strong relationship between Quadriceps angle and Tibiofemoral angle (r= 0.73, P<0.05), also a statistically significant difference regarding dominance, sports practice and gender (P-value<0.05). Conclusion: there is a strong direct relation between q-angle and tf-angle which means that the greater one of them the greater the other and vice-versa
