THE PREVALENCE OF PATELLOFEMORAL JOINT DYSFUNCTION IN FEMALE STUDENTS WITH 18-25 Y/O.

Background & Aim: Patellofemoral joint dysfunction syndrome (PFD) or chondromalacia is a non-traumatic disorder in knee joint. This syndrome is one of the most common disorders in the young adults and can cause knee osteoarthritis in old age. This study was done to determine the prevalence of PFD sx in the female students. Materials & Methods: A simple sampling was done on the 131 female students with mean ages of 21.5y/o. The data were collected by a questionnaire and four clincial tests. If Clarkeʹs sign in extension position of knee joint was positive, PFD had been determined. Analyse was done by chi-square and t-test and pearson correlation coefficient. Results: The results revealed that the prevalence of PFD sx was 24.4%. Also no significant correlation was found between PFD sx and quadriceps angle. Conclusion: The prevalence of PFD sx in young age is high. Therefore in order to decrease the osteoarthritis of knee joint in old age prevention of PFD sx must be considered in adolescence with proper teaching and treatment.
