Abstract (2. Language): 
The quadriceps femoris angle (Q angle) is used as a criterion for the diagnosis of knee disorders and analyzing the mechanical properties of knee joint. This study was designed to determine the normal values of Q angle and the relationships between Q angle and gender, age, sport age, sport branch training number per week movement and selected anatomical measurements. 41 students at School of Physical Education and Sports of Çukurova University (22 men, 19 women), who had no history of knee disorders, were participated in this study. The mean age was 20.5±1.91 SD. The Q angle was measured go-niometricaily. The femur lenght and true leg lenght were measured by the meter stick. The Q angle was measured twice for left and right leg in full extension and at 90 degrees of flexion of the knee joint. MANCOVA and multiple regression followed by nonparametric Spearman R were performed using Complete Statistical System (CSS) program. Significance was set at the p<0.05 level. The mean O angle for men was 9.99±1.50 S D degrees in extension and 9.06±1.56 SD degrees in flexion; for women the mean O angle was 14.49±1.34 SD degrees in extension and 10.96±0.97 degrees in flexion. MANCOVA indicated significant effects for gender (P=0.000041) for movement (p=0.0000) and for the interaction between gender and movement (p=0.000064). There was no significant difference between each subject's two sides (p>0.05). We found that the significant relationsihps between Q angle and the following parameters: a) Gender (r=0.82, Spearman R=0.83 andp=0.0000) b) True leg lenght (r=0.49, Spearman R=0.48 andp=0.001) c) Femur lenght (r=0.37, Spearman R=0.36 and p=0.02). Taken together, the results support the belief that women have larger Q angles than men. The changes of Q angle during extension and flexion of the knee joint may be due to the replacement of patella.

Quadriceps femoris açısı (Q açısı) diz hastalıklarının tanısında ve diz ekleminin mekaniğinin incelenmesinde kullanılan bir ölçüttür. Bu çalışmada normal Q açısı değerleri ve Q açısı ile cinsiyet, yaş, sporla uğraşma yılı, haftalık antrenman sayısı, spor dalı, hareket ve anatomik ölçümler arasındaki ilişki araştırılmıştır. Çalışmaya diz eklemi zedelenmesi bulunmayan, Çukurova Üniversitesi Beden Eğitimi ve Spor Bölümünde okuyan, yaş ortalaması 20.5±1.91 olan 22 erkek, 19 kız 41 öğrenci katılmıştır. Q açısı goniomètre, femur uzunluğu ve alt ekstremite uzunluğu ise mezura ile ölçülmüştür. Q açısı diz eklemi tam ekstensiyonda ve 90° fleksiyonda iken olmak üzere sağ ve sol ekstremiteden ikişer kez ölçülmüştür. İstatistiksel analizler için CSS programında MANCOVA, çoklu regresyon ve non-parametric Spearman R testi kullanılmıştır. Bütün testlerde anlamlılık düzeyi p<0.05 olarak kabul edilmiştir. Q açısı erkeklerde, ekstensiyonda 9.99±1.50, fleksiyonda 9.06±1.56; kızlarda, ekstensiyonda 14.49±1.34, fleksiyonda 10.96±0.97 derece olarak bulunmuştur. Kızlar ve erkekler arasında her iki harekette de istatistiksel olarak ileri derecede anlamlı fark bulunmuştur. (Cinsiyet için p=0.000041; hareket için p=0.00000, cinsiyet ve hareket etkileşimi için p=0.000064). Aynı bireyde sağ ve sol eks-tremitedeQ açısı bakımından anlamlı fark bulunmamıştır. (P>0.05).istatistiksel analizler sonucu Q açısı ile şu faktörler arasında anlamlı ilişki saptanmıştır: a) Cinsiyet (r=0.82, Spearman R=0.83 ve p=0.0000) b) Alt ekstremite uzunluğu (r=-0.49, Spearman R=0.48 ve p=0.001), c) Femur uzunluğu (r=0.37, Spearman R=0.36 ve p=0.02). Kızlarda Q açısının geniş olması pelvis bölgesinin genişliğine bağlanmaktadır. Fleksiyonda açının daha küçük olması ise, hareket sırasında patellanın yer değiştirmesinden kaynaklanmaktadır.
