Background: Nowadays many young active females are diagnosed with anterior knee pain or patellofemoral pain disorder. Q angle is an essential parameter to check the alignment of the patella within the quadriceps muscle. Higher Q angle may cause patellofemoral pain which may lead to patellar subluxation. Previous studies supports that there is a decrement in Q angle during maximal isometric quadriceps contraction. Thus, the purpose of this study is to evaluate Q angle value among young females in both supine and standing. Method: 66 subjects participated in this study who have no significant history of any knee pathology. The Q angle was measured in relaxed state of quadriceps and during isometric contraction with knee in full extension on right and left side in both supine and standing. The Q angle was measured using universal goniometer. Data was collected from each subject and analyzed using SPSS software 28.00. Results: The result of this study shows that there was a significant decrease in q angle values during relaxed state and isometric contraction ofquadriceps in both supine and standing positions. While there was no significant difference in Q angle values when both the positions were compared. Conclusion: The study concludes that the Q angle decreases with isometric quadriceps contraction on both the sides in supine and standing positions but there was no difference in q angle values in both body positions.
