[Evaluation of correlation between Q-angle and anterior knee pain]

ABSTRACT

Knee pain is one of common cause that patients refer to orthopedic clinics and has several reasons. One group is reversible and other is irreversible. Excessive Q-angle composes of 10% causes of knee pain reasons and is recovered [90%] by physical therapy. This study was conducted for evaluation of correlation of knee pain with excessive Q-angle and comparing both sexes and ages groups. 100 patients [50 men and 50 women] in a simple convenience study were enrolled in this research. Q-angle and pain scale [VSA] were measured and then Q-angle deviation in both sexes and ages groups analyzed using ANOVA, t-test. Spearman test with SPSS17 software. The correlation between severity of knee pain and Q-angle in general population and in both sex was significant using of Spearman's test. There was no significant correlation between different ages and Q-angle. There was significant relationship between Q-angle in men and women [P<0.05]. 10% of men, 18% of women and 14% of general population refered to orthopedic clinic had Q-angle greater than normal range. Higher level of Q-angle in females might be related to anatomical differences and high level of estrogen, multiparity, malnutrition, genetical differences and excessive activity, in females
