Objectives:
This study aims to determine the relationship between the quadriceps angle (Q-angle) and tibiofemoral angle (TF-angle) among adolescents. We also compared the angles between both the lower limbs with respect to dominancy, measured the difference between athletic and non-athletic angles, and explored the variations of these features in different sports.
Methods:
We recruited 150 adolescents aged between 12 and 18 years and classified them into two groups; group A (athletic group), including four subgroups of players of different sports, and group B (non-athletic group). We measured the Q-angle and TF-angle via computerized photogrammetry.
Results:
This study showed a strong and statistically significant relationship between Q-angle and TF-angle (p < 0.05). Similarly, we found a statistically significant difference in the Q-angle and TF-angle between both the lower limbs concerning dominance. Lastly, we identified a significant difference between the athletic and non-athletic groups. However, there was no difference among players of different sports (p > 0.05).
Conclusion:
Our study showed a strong relationship between the Q-angle and the TF-angle. The Q-angle and the TF-angle should be measured bilaterally and the nature of sports should also be considered.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
