Abstract

Background: Patellofemoral pain syndrome is the most common problem in young and sporting population. Both the Q angle and the condylar distance tend to affect each other and may be used to predict the Patellofemoral pain syndrome. Q angle reflects pathomechanics and biomechanics of the patellofemoral joint. Aim of this research was to give normative data of Q angle and Intercondylar distance in Indian population and observe if any undertaken body parameters have any relation with patellofemoral pain syndrome. Here, we also aim to know which parameter (Intercondylar distance / Quadriceps angle) is the better predictor for Patellofemoral pain syndrome in young Indian populat Subjects and methods: This study was composed of 60 healthy individuals (sedentary). Here, 60 individuals were also included who were diagnosed with Patellofemoral pain syndrome. Q angle (goniometric method) and Intercondylar distance (manual caliper) of each participants were calculated. Comparison of body parameters was done by independent t-test. The association between the parameters and the Q angle was investigated using Pearson’s correlation coefficient. Cohen’s Kappa coefficient of the two parameters; Intercondylar distance & Quadriceps angle was calculated, to know which parameter can better predict the Patellofemoral pain syndrome in Indian young population. Results: Females had higher value of Q angle than their counterpart (p<0.05). On calculating the Pearson Coefficient correlation between Q angle and Intercondylar distance, we observed negative correlation between Q angle and Intercondylar distance (p<0.05) in sedentary. This revealed a significant discovery regarding the Indian population i.e. with the increase in value of Intercondylar distance, there is a decrease in Q angle. In this study, we also calculated Cohen’s kappa coefficient and on calculation, we found that the Q angle was better indicator for Patellofemoral pain syndrome than Intercondylar distance. Conclusion: Quadriceps femoris angle should be used to assess the bio-mechanical function of knee joint and as an indicator to predict Patellofemoral pain syndrome. Females had higher Q angle in comparison to males, making them more susceptible to the disorders of patellofemoral joint. Q angle has far greater significance to sportspersons, especially females who involve in different competitive sports and physical activities. Thus, it’s the high time to not only carry out the periodic screening for Q angle in susceptible population but also use it in clinical practice and the prognosis of affected individual after treatment.
